The directory is generated on every build and deployed from CI, so it does not belong in version control. Files remain on disk; only tracking is removed. --- site/404.html | 1008 --- site/CNAME | 1 - site/DZ Mainnet-beta Connection/index.html | 1417 ---- site/DZ Testnet Connection/index.html | 1448 ----

Validator Mainnet-Beta Connection in IBRL Mode

-
-

By connecting to DoubleZero I agree to the DoubleZero Terms of Service

-
-

Connecting to Mainnet-Beta in IBRL Mode

-
-

Note

-

IBRL mode does not require restarting validator clients, because it uses your existing public IP address.

-
-

Solana Mainnet Validators will complete connection to DoubleZero Mainnet-beta, which is detailed on this page.

-

Each Solana validator has its own identity keypair; from this, extract the public key known as the node ID. This is the validator's unique fingerprint on the Solana network.

-

With the DoubleZeroID and node ID identified, you will prove ownership of your machine. This is done by creating a message which includes the DoubleZeroID signed with the validator's identity key. The resulting cryptographic signature serves as verifiable proof that you control the validator.

-

Finally, you will submit a connection request to DoubleZero. This request communicates: "Here is my identity, here is proof of ownership, and here is how I intend to connect." DoubleZero validates this information, accepts the proof, and provisions network access for the validator on DoubleZero.

-

This guide allows for 1 Primary Validator to register itself, and up to 3 backup/failover machines at the same time.

-

Prerequisites

-
    -
  • Solana CLI installed and on $PATH
    • -
  • For validators: Permission to access to the validator identity keypair file (e.g., validator-keypair.json) under the sol user
    • -
  • For validators: Verify the Identity key of Solana validator being connected has at least 1 SOL on it
    • -
  • Firewall rules permit outbound connections for DoubleZero and Solana RPC as needed including - GRE (ip proto 47) and BGP (169.254.0.0/16 on tcp/179)
    • -
-
-

Info

-

The Validator ID will be checked against Solana gossip to determine the target IP. The target IP, and the DoubleZero ID will then be used when opening a GRE tunnel between your machine and the target DoubleZero Device.

-

Consider: In the case where you have a junk ID and Primary ID on at the same IP, only the Primary ID will be used in registration of the machine. This is because the junk ID will not appear in gossip, and therefore cannot be used to verify the IP of the target machine.

-
-

1. Environment Configuration

-

Please follow the setup instructions before proceeding.

-

The last step in setup was to disconnect from the network. This is to ensure that only one tunnel is open on your machine to DoubleZero, and that tunnel is on the correct network.

-
-

To configure the DoubleZero Client CLI (doublezero) and daemon (doublezerod) to connect to DoubleZero mainnet-beta: -

DESIRED_DOUBLEZERO_ENV=mainnet-beta \
-    && sudo mkdir -p /etc/systemd/system/doublezerod.service.d \
-    && echo -e "[Service]\nExecStart=\nExecStart=/usr/bin/doublezerod -sock-file /run/doublezerod/doublezerod.sock -env $DESIRED_DOUBLEZERO_ENV" | sudo tee /etc/systemd/system/doublezerod.service.d/override.conf > /dev/null \
-    && sudo systemctl daemon-reload \
-    && sudo systemctl restart doublezerod \
-    && doublezero config set --env $DESIRED_DOUBLEZERO_ENV  > /dev/null \
-    && echo "✅ doublezerod configured for environment $DESIRED_DOUBLEZERO_ENV"
-

-

You should see the following output: -✅ doublezerod configured for environment mainnet-beta

-

After about 30 seconds you will see the DoubleZero devices available:

2. Open port 44880

-

Users need to open port 44880 to utilize some routing features.

-

To open port 44880 you could update IP tables such as:

-
-
sudo iptables -A INPUT -i doublezero0 -p udp --dport 44880 -j ACCEPT
-sudo iptables -A OUTPUT -o doublezero0 -p udp --dport 44880 -j ACCEPT
-
-
-

note the -i doublezero0, -o doublezero0 flags which restrict this rule to only the DoubleZero interface

-

Or UFW such as:

-
-
sudo ufw allow in on doublezero0 to any port 44880 proto udp
-sudo ufw allow out on doublezero0 to any port 44880 proto udp
-
-
-

note the in on doublezero0, out on doublezero0 flags which restrict this rule to only the DoubleZero interface

-

3. Attest Validator Ownership

-
-

With your DoubleZero Environment set, it is now time to attest to your Validator Ownership.

-

The DoubleZero ID you created in the setup of your primary validator must be used on all backup machines.

-

The ID on your primary machine can be found with doublezero address The same ID must be in ~/.config/doublezero/id.json on all machines in the cluster.

-

In order to accomplish this you will first verify the machine you are running the commands from is your Primary Validator with:

-
doublezero-solana passport find-validator -u mainnet-beta
-
-

This verifies that the validator is registered in gossip and appears in the leader schedule.

-

Expected output:

-
Connected to Solana: mainnet
-
-DoubleZero ID: YourDoubleZeroAddress11111111111111111111111111111
-Detected public IP: 11.11.11.111
-Validator ID: ValidatorIdentity111111111111111111111111111
-Gossip IP: 11.11.11.111
-In Leader scheduler
-✅ This validator can connect as a primary in DoubleZero 🖥️  💎. It is a leader scheduled validator.
-
-
-

Info

-

The same workflow is used for one, or many machines. -To register one machine exclude the arguments "--backup-validator-ids" or "backup_ids=" from any commands on this page.

-
-

Now, on all backup machines you intend to run your Primary Validator on execute the following: -

doublezero-solana passport find-validator -u mainnet-beta
-

-

Expected output:

-

Connected to Solana: mainnet
-
-DoubleZero ID: YourDoubleZeroAddress11111111111111111111111111111
-Detected public IP: 22.22.22.222
-Validator ID: ValidatorIdentity222222222222222222222222222
-Gossip IP: 22.22.22.222
-In Not in Leader scheduler
- ✅ This validator can only connect as a backup in DoubleZero 🖥️  🛟. It is not leader scheduled and cannot act as a primary validator.
-
-This output is expected. The backup node cannot be in the leader schedule at time of pass creation.

-

You will now run this command on all backup machines you plan to use your Primary Validator vote account, and identity on.

-
-
-

Prepare the Connection

-

Run the following command on the Primary Validator machine. This is the machine you have active stake on, that is in the leader schedule with your primary validator ID in solana gossip on the machine you are running the command from:

-
doublezero-solana passport prepare-validator-access -u mainnet-beta \
-  --doublezero-address YourDoubleZeroAddress11111111111111111111111111111 \
-  --primary-validator-id ValidatorIdentity111111111111111111111111111 \
-  --backup-validator-ids ValidatorIdentity222222222222222222222222222,ValidatorIdentity33333333333333333333333333,ValidatorIdentity444444444444444444444444444>
-
-

Example output:

-

DoubleZero Passport - Prepare Validator Access Request
-Connected to Solana: mainnet-beta
-
-Primary validator 🖥️  💎:
-  ID: ValidatorIdentity111111111111111111111111111

-  Leader scheduler: ✅ OK (Stake: 1,050,000.00 SOL)
-
-Backup validator 🖥️ 🛡️:
-  ID: ValidatorIdentity222222222222222222222222222
-  Gossip: ✅ OK (22.22.22.222)
-  Leader scheduler:  ✅ OK (not a leader scheduled validator)
-
-
-Backup validator 🖥️ 🛡️:
-  ID: ValidatorIdentity333333333333333333333333333
-  Gossip: ✅ OK (33.33.33.333)

-  Gossip: ✅ OK (33.33.33.333)
-  Leader scheduler:  ✅ OK (not a leader scheduled validator)
-
-  To request access, sign the following message with your validator's identity key:
-
-  solana sign-offchain-message \
-     service_key=YourDoubleZeroAddress11111111111111111111111111111,backup_ids=ValidatorIdentity222222222222222222222222222,ValidatorIdentity33333333333333333333333333,ValidatorIdentity444444444444444444444444444 \
-     -k <identity-keypair-file.json>
-
-Note the output at the end of this command. It is the structure for the next step.

-
-

4. Generate Signature

-
-

At the end of the last step, we received a pre-formatted output for solana sign-offchain-message

-

From the above output we will run this command on the Primary Validator machine.

5. Initiate a Connection Request in DoubleZero

-
-

Use the request-validator-access command to create an account on Solana for the connection request. The DoubleZero Sentinel agent detects the new account, validates its identity and signature, and creates the access pass in DoubleZero so the server can establish a connection.

-

Use the node ID, DoubleZeroID, and signature.

-
-

Note

-

In this example we use -k /home/user/.config/solana/id.json to find the validator Identity. Use the appropriate location for your local deployment.

-
-
doublezero-solana passport request-validator-access -k <path to keypair> -u mainnet-beta \
---primary-validator-id ValidatorIdentity111111111111111111111111111 \

-
-

Output:

-

This output can be used to see the transaction on a Solana explorer. Be sure to change the explorer to mainnet. This verification is optional.

-
-

If successful, DoubleZero will register the primary with its backups. You may now failover between the IPs registered in the access pass. DoubleZero will maintain connectivity automatically when switching to backup nodes registered in this way.

-
-

6. Connect in IBRL Mode

-
-

On the server, with the user which will connect to DoubleZero, run the connect command to establish the connection to DoubleZero.

-
doublezero connect ibrl
-
-

You should see output indicating provisioning, such as:

-

DoubleZero Service Provisioning
-🔗  Start Provisioning User...
-Public IP detected: 137.184.101.183 - If you want to use a different IP, you can specify it with `--client-ip x.x.x.x`

Connecting to Testnet in IBRL Mode

-
-

Note

-

IBRL mode does not require restarting validator clients, because it uses your existing public IP address.

-
-

Solana Testnet Validators will complete connection to DoubleZero Testnet, which is detailed on this page.

-

Each Solana validator has its own identity keypair; from this, extract the public key known as the node ID. This is the validator's unique fingerprint on the Solana network.

-

With the DoubleZeroID and node ID identified, you will prove ownership of your machine. This is done by creating a message which includes the DoubleZeroID signed with the validator's identity key. The resulting cryptographic signature serves as verifiable proof that you control the validator.

-

Finally, you will submit a connection request to DoubleZero. This request communicates: "Here is my identity, here is proof of ownership, and here is how I intend to connect." DoubleZero validates this information, accepts the proof, and provisions network access for the validator on DoubleZero.

-

This guide allows for 1 Primary Validator to register itself, and up to 3 backup/failover machines at the same time.

-

Prerequisites

-
    -
  • Solana CLI installed and on $PATH
    • -
  • For validators: Permission to access to the validator identity keypair file (e.g., validator-keypair.json) under the sol user
    • -
  • For validators: Verify the Identity key of Solana validator being connected has at least 1 SOL on it
    • -
  • Firewall rules permit outbound connections for DoubleZero and Solana RPC as needed including - GRE (ip proto 47) and BGP (169.254.0.0/16 on tcp/179)
    • -
-
-

Info

-

The Validator ID will be checked against Solana gossip to determine the target IP. The target IP, and the DoubleZero ID will then be used when opening a GRE tunnel between your machine and the target DoubleZero Device.

-

Consider: In the case where you have a junk ID and Primary ID on at the same IP, only the Primary ID will be used in registration of the machine. This is because the junk ID will not appear in gossip, and therefore cannot be used to verify the IP of the target machine.

-
-

1. Environment Configuration

-

Please follow the setup instructions before proceeding.

-

The last step in setup was to disconnect from the network. This is to ensure that only one tunnel is open on your machine to DoubleZero, and that tunnel is on the correct network.

-
-

To configure the DoubleZero Client CLI (doublezero) and daemon (doublezerod) to connect to DoubleZero testnet: -

DESIRED_DOUBLEZERO_ENV=testnet \
-    && sudo mkdir -p /etc/systemd/system/doublezerod.service.d \
-    && echo -e "[Service]\nExecStart=\nExecStart=/usr/bin/doublezerod -sock-file /run/doublezerod/doublezerod.sock -env $DESIRED_DOUBLEZERO_ENV" | sudo tee /etc/systemd/system/doublezerod.service.d/override.conf > /dev/null \
-    && sudo systemctl daemon-reload \
-    && sudo systemctl restart doublezerod \
-    && doublezero config set --env $DESIRED_DOUBLEZERO_ENV  > /dev/null \
-    && echo "✅ doublezerod configured for environment $DESIRED_DOUBLEZERO_ENV"
-
-You should see the following output: -
✅ doublezerod configured for environment testnet
-

-

After about 30 seconds you will see the DoubleZero devices available:

-

-

-
-

Mainnet output will be identical in structure, but with many more available devices. -

-

2. Open port 44880

-

Users need to open port 44880 to utilize some routing features.

-

To open port 44880 you could update IP tables such as:

-
-
sudo iptables -A INPUT -i doublezero0 -p udp --dport 44880 -j ACCEPT
-sudo iptables -A OUTPUT -o doublezero0 -p udp --dport 44880 -j ACCEPT
-
-
-

note the -i doublezero0, -o doublezero0 flags which restrict this rule to only the DoubleZero interface

-

Or UFW such as:

-
-
sudo ufw allow in on doublezero0 to any port 44880 proto udp
-sudo ufw allow out on doublezero0 to any port 44880 proto udp
-
-
-

note the in on doublezero0, out on doublezero0 flags which restrict this rule to only the DoubleZero interface

-

3. Attest Validator Ownership

-
-

With your DoubleZero Environment set, it is now time to attest to your Validator Ownership.

-

The DoubleZero ID you created in the setup of your primary validator must be used on all backup machines.

-

The ID on your primary machine can be found with doublezero address The same ID must be in ~/.config/doublezero/id.json on all machines in the cluster.

-

In order to accomplish this you will first verify the machine you are running the commands from is your Primary Validator with:

-
doublezero-solana passport find-validator -ut
-
-

This verifies that the validator is registered in gossip and appears in the leader schedule.

-

Expected output:

-
Connected to Solana: testnet
-
-DoubleZero ID: YourDoubleZeroAddress11111111111111111111111111111
-Detected public IP: 11.11.11.111
-Validator ID: ValidatorIdentity111111111111111111111111111
-Gossip IP: 11.11.11.111
-In Leader scheduler
-✅ This validator can connect as a primary in DoubleZero 🖥️  💎. It is a leader scheduled validator.
-
-
-

Info

-

The same workflow is used for one, or many machines. -To register one machine exclude the arguments "--backup-validator-ids" or "backup_ids=" from any commands on this page.

-
-

Now, on all backup machines you intend to run your Primary Validator on execute the following:

-
doublezero-solana passport find-validator -ut
-
-

Expected output:

-

Connected to Solana: testnet
-
-DoubleZero ID: YourDoubleZeroAddress11111111111111111111111111111
-Detected public IP: 22.22.22.222
-Validator ID: ValidatorIdentity222222222222222222222222222
-Gossip IP: 22.22.22.222
-In Not in Leader scheduler
- ✅ This validator can only connect as a backup in DoubleZero 🖥️  🛟. It is not leader scheduled and cannot act as a primary validator.
-
-This output is expected. The backup node cannot be in the leader schedule at time of pass creation.

-

You will now run this command on all backup machines you plan to use your Primary Validator vote account, and identity on.

-
-
-

Prepare the Connection

-

Run the following command on the Primary Validator machine. This is the machine you have active stake on, that is in the leader schedule with your primary validator ID in solana gossip on the machine you are running the command from:

-
doublezero-solana passport prepare-validator-access -ut \
-  --doublezero-address YourDoubleZeroAddress11111111111111111111111111111 \
-  --primary-validator-id ValidatorIdentity111111111111111111111111111 \
-  --backup-validator-ids ValidatorIdentity222222222222222222222222222,ValidatorIdentity33333333333333333333333333,ValidatorIdentity444444444444444444444444444>
-
-

Example output:

-

-  Gossip: ✅ OK (33.33.33.333)
-  Leader scheduler:  ✅ OK (not a leader scheduled validator)
-
-  To request access, sign the following message with your validator's identity key:
-
-  solana sign-offchain-message \
-     service_key=YourDoubleZeroAddress11111111111111111111111111111,backup_ids=ValidatorIdentity222222222222222222222222222,ValidatorIdentity33333333333333333333333333,ValidatorIdentity444444444444444444444444444 \
-     -k <identity-keypair-file.json>
-
-Note the output at the end of this command. It is the structure for the next step.

-
-

4. Generate Signature

-
-

At the end of the last step, we received a pre-formatted output for solana sign-offchain-message

-

From the above output we will run this command on the Primary Validator machine.

5. Initiate a Connection Request in DoubleZero

-
-

Use the request-validator-access command to create an account on Solana for the connection request. The DoubleZero Sentinel agent detects the new account, validates its identity and signature, and creates the access pass in DoubleZero so the server can establish a connection.

-

Use the node ID, DoubleZeroID, and signature.

-
-

Note

-

In this example we use -k /home/user/.config/solana/id.json to find the validator Identity. Use the appropriate location for your local deployment.

-
-
doublezero-solana passport request-validator-access -k <path to keypair> -ut \
---primary-validator-id ValidatorIdentity111111111111111111111111111 \

-
-

Output:

-

This output can be used to see the transaction on a Solana explorer. Be sure to change the explorer to testnet. This verification is optional.

-

-
-

If successful, DoubleZero will register the primary with its backups. You may now failover between the IPs registered in the access pass. DoubleZero will maintain connectivity automatically when switching to backup nodes registered in this way.

-
-

6. Connect in IBRL Mode

-
-

On the server, with the user which will connect to DoubleZero, run the connect command to establish the connection to DoubleZero.

-
doublezero connect ibrl
-
-

You should see output indicating provisioning, such as:

-

Connecting to Mainnet-Beta and Testnet in IBRL Mode

-
-

Note

-

IBRL mode does not require restarting validator clients, because it uses your existing public IP address.

-
-

Permissioned Users will complete connection to DoubleZero Mainnet-beta, which is detailed on this page.

-

1. Environment Configuration

-

Please follow the setup instructions before proceeding.

-

The last step in setup was to disconnect from the network. This is to ensure that only one tunnel is open on your machine to DoubleZero, and that tunnel is on the correct network.

-

To configure the DoubleZero Client CLI (doublezero) and daemon (doublezerod) to connect to DoubleZero testnet: -

DESIRED_DOUBLEZERO_ENV=testnet \
-    && sudo mkdir -p /etc/systemd/system/doublezerod.service.d \
-    && echo -e "[Service]\nExecStart=\nExecStart=/usr/bin/doublezerod -sock-file /run/doublezerod/doublezerod.sock -env $DESIRED_DOUBLEZERO_ENV" | sudo tee /etc/systemd/system/doublezerod.service.d/override.conf > /dev/null \
-    && sudo systemctl daemon-reload \
-    && sudo systemctl restart doublezerod \
-    && doublezero config set --env $DESIRED_DOUBLEZERO_ENV  > /dev/null \
-    && echo "✅ doublezerod configured for environment $DESIRED_DOUBLEZERO_ENV"
-
-To configure the DoubleZero Client CLI (doublezero) and daemon (doublezerod) to connect to DoubleZero mainnet-beta: -
DESIRED_DOUBLEZERO_ENV=mainnet-beta \
-    && sudo mkdir -p /etc/systemd/system/doublezerod.service.d \
-    && echo -e "[Service]\nExecStart=\nExecStart=/usr/bin/doublezerod -sock-file /run/doublezerod/doublezerod.sock -env $DESIRED_DOUBLEZERO_ENV" | sudo tee /etc/systemd/system/doublezerod.service.d/override.conf > /dev/null \
-    && sudo systemctl daemon-reload \
-    && sudo systemctl restart doublezerod \
-    && doublezero config set --env $DESIRED_DOUBLEZERO_ENV  > /dev/null \
-    && echo "✅ doublezerod configured for environment $DESIRED_DOUBLEZERO_ENV"
-

-

You should see the following output: -

✅ doublezerod configured for environment mainnet-beta
-
-You should see the following output: -✅ doublezerod configured for environment testnet

-

After about 30 seconds you will see the DoubleZero devices available:

The DoubleZero protocol collects SOL-denominated revenue from its validator users but distributes 2Z-denominated rewards to contributors. Thus, it must convert SOL into 2Z.

-

To do so, eligible participants can trade against a DoubleZero swap contract, purchasing SOL from the contract and selling it 2Z. Pricing is based on Pyth price feeds with a programmatic discount mechanism.

-

This short guide explains how to use the program.

-

Review the Disclaimer at the end of this document before accessing or using the code or any related materials.

-
-

Program Design

-

The swap program is effectively a one-sided liquidity pool that sells SOL in a fixed batch size of 1 SOL per trade. Any eligible participant can withdraw SOL from the program by depositing 2Z, at a price that is determined by an oracle price from Pyth and a dynamic discount. Over time, this executes the program’s goal of turning native tokens into 2Z.

-

To utilize, a trader must provide two recent Pyth prices (SOL/USD and 2Z/USD) and a quantity of 2Z. The program then calculates the 2Z needed to purchase that 1 SOL based on the implied SOL/2Z price. It then takes a few additional steps:

-
    -
  • It checks that the Pyth prices are sufficiently fresh, i.e. they are no more than 5 seconds stale.
    • -
  • It checks that the confidence intervals of the two prices are sufficiently small. That is, the sum of two Laplacing standard deviations (i.e. parameter conf in the Pyth price) for the two prices, normalized by their levels, must be less than or equal to 30 basis points.
    • -
  • It adjusts the SOL/2Z price by a dynamic discount, expressed as a percent of the Pyth price. This discount is a function of the time since the last trade. The formula below specifies the discount, assuming the last trade was made at slot \(s_{\text{last}}\) and the current slot is \(s_{\text{now}}\). (For instance, if 200 slots have elapsed since the last trade, the discount is 40 basis points.)
    • -
-
\[ -\text{discount} = \min\{0.00002 \times \left(s_{\text{now}} - s_{\text{last}}\right), 0.01\} -\]
-

At this point, if the trader has provided enough 2Z to execute the transaction at this computed price (inclusive of the discount), it executes at this computed price. It returns to the trader the purchased quantity of SOL and any excess 2Z.

-

The contract then permits no more trades for that slot. This is to prevent the contract from paying excessively high slippage should the Pyth price be far from the true price at any given point in time in ways that the existing filters do not catch issues.

Gasless Atomic Execution

-

This section will detail how to use the command harvest-dz. This command will atomically perform 2 actions. -1. The command requests a quote from Jupiter vs the native SOL <> 2Z conversion program. -2. When the Jupiter route yields more 2Z per SOL than the native conversion program requires, harvest-2z executes a swap, returning to your wallet 1 SOL plus the difference in 2Z.

-

Harvest 2Z

-

To execute, run the following: -

doublezero-solana revenue-distribution harvest-2z
-
-Output will resemble: -
Harvested 5.98151278 2Z tokens with 1.000000000 SOL
-
-The command can also be simulated with the --dry-run argument. Dry-run will produce program logs and an output resembling:

-
Simulated harvesting 5.98151278 2Z tokens with 1.000000000 SOL
-
-
-

Protocol Conversion

-

This section discusses checking conversion rates and executing the conversion using the doublezero-solana CLI. And at the end, we discuss the interface for custom-built integrations with the DoubleZero swap contract.

-

How to check the SOL/2Z conversion price via doublezero-solana

-

To find the SOL/2Z conversion rates on mainnet-beta, run the following command:

-
doublezero-solana revenue-distribution fetch sol-conversion
-
-

And the output you would see will resemble:

-
| field           | description                  | value         | note                          |
-|-----------------|------------------------------|---------------|-------------------------------|
-| Swap Rate       | 2Z amount for 1 SOL          | 805.72612992  |                               |
-| Swap Rate       | 2Z amount for 1 SOL          | 805.38772494  | Includes 0.04200000% discount |
-| Journal Balance | SOL available for conversion | 438.670881289 |                               |
-
-

The Journal Balance informs the user how much SOL liquidity there is in the Revenue Distribution smart contract. A user can trade as long as the Journal Balance exceeds the fixed trade size of 1 SOL.

-

The first row displays the "true" SOL/2Z conversion price via an offchain oracle. The second row is the conversion price used on-chain for the swap, which simply adjusts the true price for the algorithmic discount.

-

How to convert your 2Z to SOL via doublezero-solana

-

To convert your 2Z tokens to SOL, run the following command:

-
doublezero-solana revenue-distribution convert-2z
-
-

By default, if there is enough SOL liquidity and your ATA has enough 2Z to perform the swap, this transaction will succeed. You can more finely-tune the swap by specifying the following arguments:

-
      --limit-price <DECIMAL>                    Limit price defaults to the current SOL/2Z oracle price
-      --source-2z-account <PUBKEY>               Token account must be owned by the signer. Defaults to signer ATA if not specified
-      --checked-sol-amount <SOL>                 Explicitly check SOL amount. When specified, this amount will be checked against the fixed fill quantity
-
-

The specified limit price determines the worst-case price you are willing to accept when performing the SOL/2Z conversion. For example, let us say the discounted 2Z price for SOL is 800, which means 800 2Z tokens for 1 SOL. If you specify a limit price of 790, you are not willing to perform the swap because you are requiring that you only swap at most 790 2Z tokens for 1 SOL. But if you specify 810, the trade will go through because you were willing to swap at most 810 2Z tokens (and in this case, you will have only swapped 800 2Z tokens in this transaction).

-

The source 2Z token account overrides the default ATA using the signer as the owner of this 2Z ATA. But if you have another token account you want to use to perform the swap, provide the pubkey for it with this argument.

-

Optionally, you may specify the checked SOL amount to the standard fill size (set to 1 SOL at launch). If it does not align with the program’s fill size, the swap fails. This mitigates the risk that the program’s fill size changes and you do not notice.

-

Interface to Buy SOL

-

The interface and doublezero-solana CLI live in this repo. The source code for the DoubleZero swap contract interface can be found here. The program ID is 9DRcqsJUCo8CL2xDCXpogwzLEVKRDzSyNtVgXqsXHfDs.

-

A convenient way of generating the accounts needed for the buy SOL instruction is using the new method (found in instruction/account.rs).

-
pub fn new(
-    fill_registry_key: &Pubkey,
-    user_token_account_key: &Pubkey,
-    dz_mint_key: &Pubkey,
-    user_key: &Pubkey,
-) -> Self;
-
-

The fill_registry_key can be fetched either from the ProgramState

-
pub struct ProgramState {
-    pub admin_key: Pubkey,
-    pub fills_registry_key: Pubkey, // this key
-    pub is_paused: bool,
-    pub configuration_registry_bump: u8,
-    pub program_state_bump: u8,
-    pub deny_list_registry_bump: u8,
-    pub withdraw_authority_bump: u8,
-    pub last_trade_slot: u64,
-    pub deny_list_authority: Pubkey,
-}
-
-

Alternatively, you can call getProgramAccounts via Solana RPC with its discriminator. But we recommend caching this pubkey since it will never change.

-

The user_key is a signer for the buy SOL instruction and must be the owner of the user_token_account_key. As described above, this does NOT need to be an ATA. As long as your 2Z token account is owned by the user_key, this instruction will succeed.

-

The BuySolAccounts struct implements Into<Vec<AccountMeta>> so you can generate all of the account metas you need in order to build the instruction.

-

Instruction data is

-
    SolConversionInstructionData::BuySol {
-        limit_price: u64,
-        oracle_price_data: OraclePriceData,
-    },
-
-

This instruction data is Borsh-serialized and has an 8-byte Anchor selector, which will all serialize when using BorshSerialize::serialize.

-

The oracle price data can be fetched from this public endpoint: https://sol-2z-oracle-api-v1.mainnet-beta.doublezero.xyz/swap-rate. The data is serde-deserializable using the OraclePriceData struct found in oracle.rs.

-
#[derive(Debug, BorshDeserialize, BorshSerialize, Clone, Default, PartialEq, Eq)]
-#[cfg_attr(
-    feature = "serde",
-    derive(serde::Deserialize),
-    serde(rename_all = "camelCase")
-)]
-pub struct OraclePriceData {
-    pub swap_rate: u64,
-    pub timestamp: i64,
-    pub signature: String,
-}
-
-

Example of how to fetch using the reqwest crate:

-
use anyhow::{Context, Result};
-
-pub async fn try_request_oracle_conversion_price(oracle_endpoint: &str) -> Result<OraclePriceData> {
-    reqwest::Client::new()
-        .get(oracle_endpoint)
-        .header("User-Agent", "SOL buyoooooooor")
-        .send()
-        .await?
-        .json()
-        .await
-        .with_context(|| format!("Failed to request SOL/2Z price from {oracle_endpoint}"))
-}
-
-

With the program ID, accounts and instruction data, you should be able to build the instruction to buy SOL from the DoubleZero swap contract.

If you are a validator who is already connected to DoubleZero you may continue this guide.

-

1. Client Configuration

-

Jito-Agave (v3.1.9+)

-
    -
  1. -

    In your validator start script, add: --shred-receiver-address 233.84.178.1:7733

    -

    You are able to send to Jito and the bebop group at the same time.

    -

    example:

    -
    #!/bin/bash
-export PATH="/home/sol/.local/share/solana/install/releases/v3.1.9-jito/bin:$PATH"
-BLOCK_ENGINE_URL=https://ny.mainnet.block-engine.jito.wtf
-RELAYER_URL=http://ny.mainnet.relayer.jito.wtf:8100
-SHRED_RECEIVER_ADDR=<JitoBlockEngineAddress>
-<...The rest of your config...>
---shred-receiver-address 233.84.178.1:7733
-
    -
    2. -
  2. -

    Restart your validator.

    -
    3. -
  3. Connect to the DoubleZero multicast group bebop as a publisher: doublezero connect ibrl && doublezero connect multicast --publish bebop
    4. -
-

Frankendancer

-
    -
  1. -

    In config.toml, add:

    -
    [tiles.shred]
-additional_shred_destinations_leader = [ "233.84.178.1:7733", ]
-
    -
    2. -
  2. -

    Restart your validator.

    -
    3. -
  3. Connect to the DoubleZero multicast group bebop as a publisher: doublezero connect ibrl && doublezero connect multicast --publish bebop
    4. -
-

2. Confirm you're publishing leader shreds

-

Once you are connected you may check this dashboard to confirm you are publishing shreds. You will not see confirmation until after you have published leader shreds for at least one slot.

-

3. Validator Rewards

-

For each epoch where validators publish leader shreds, they will be proportionately rewarded for their contribution based on subscriptions. The specifics of this system will be announced, and detailed at a later date.

-

Troubleshooting

-

Retransmitting:

-
    -
  1. -

    A common cause of shred retransmission is a simple config. You may have the flag enabled to send retransmit shreds in your startup script; you will need to disable it.

    -

    The flag to remove in Jito-Agave is: --shred-retransmit-receiver-address.

    -
    2. -
  2. -

    Check the publisher dashboard and see if you have any retransmitted shreds. In the table, look at the No Retransmit Shreds column—a red X means you are retransmitting.

    -
    -

    epoch view

    -

    Note that there are different time windows to view the publisher dashboard. If you see retransmit in the 2 epoch view, but have made a recent change, try switching to the recent slot view.

    -
    -

    Publisher check dashboard

    -
    3. -
  3. -

    Find your client IP and look up your user in DoubleZero Data.

    -

    DoubleZero Data users

    -
    4. -
  4. -

    Click on Multicast to open your multicast view.

    -

    The screenshot below shows: Retransmitting (undesirable) steady outbound traffic with no leader-slot pattern.

    -

    User multicast view — retransmit example

    -

    The screenshot below shows: Healthy (publishing only leader shreds) outbound traffic in spikes, known as a sawtooth pattern, which line up with your leader slots.

    -

    User multicast view — healthy publisher example

    -
    5. -
-

The chart shows whether you are sending only leader shreds. Traffic spikes should line up with when you have a leader slot. When you have no leader slot there should be no traffic. If you are retransmitting, you will see a steady flow of traffic instead of slot-aligned spikes.

Architecture

-

What makes up the different actors and components of the DoubleZero network?

-
- Image title -
-
Figure 1: Network architecture components
-
-

Contributors

-

The DoubleZero network is made up of connectivity and packet processing contributions from a growing community of distributed network infrastructure providers in cities across the globe. Contributors bring fiber optic cable links and information processing resources to the protocol to provide the decentralized mesh network.

-

Network Bandwidth Contributors

-

Network contributors must provide dedicated bandwidth between two points, operate DoubleZero compatible devices (DZDs) at each end, and a connection to the internet at each end. Network contributors must also run DoubleZero software on each DZD to provide services like multicast, user lookup, and edge filtration services.

-

The physical links of the DoubleZero network are provided in the form of fiber optic cables, commonly referred to as wavelength services. Network contributors commit underutilized network links, owned or leased from infrastructure providers, between two or more data centers. These links are terminated at both ends by DoubleZero Devices, which are physical network switching enclosures running instances of the DoubleZero Agent software.

-

DoubleZero Exchange (DZX / Cross-connect Site)

-

DoubleZero Exchanges (DZXs) are interconnect points in the mesh network where different contributor links are bridged together. DZXs are located in major metropolitan areas around the world where network intersections occur. Network contributors must cross-connect their links into the broader DoubleZero mesh network at the DZXs geographically located nearest their link endpoints.

-

Computational Resource Contributors

-

Separate from network contributors, resource contributors are a decentralized group of network participants that perform various maintenance and monitoring duties necessary to sustain the technical integrity and ongoing functionality of the DoubleZero network. Specifically, they (i) track user transactions and payments; (ii) calculate fees for network contributors; (iii) record the results of (i) and (ii); (iv) administer, strictly on a non-discretionary basis, the smart contracts that control protocol tokenomics; (v) relay attestations to the applicable blockchain; and (vi) publish telemetry data regarding link quality and utilization to provide transparent, real-time performance metrics for all network contributors.

-

Components

-

DoubleZero Daemon

-

The DoubleZero Daemon software runs on servers needing to communicate over the DoubleZero network. The daemon interfaces with the host's kernel networking stack to create and manage tunnel interfaces, routing tables, and routes.

-

Activator

-

The Activator service, hosted by one or more computational resource contributing members of the DoubleZero community, monitors contract events that require IP address allocations and state changes and manages those changes on behalf of the network.

-

Controller

-

The Controller service, hosted by one or more computational resource contributors of the DoubleZero community, serves as the configuration interface for DoubleZero Device Agents to render their current configuration based on smart contract events.

-

Agent

-

The Agent software runs directly on DoubleZero Devices and applies configuration changes to the devices as interpreted by the Controller service. The Agent software polls the Controller for configuration changes, computes any differences between the canonical on-chain version of the Device state and the active configuration on the device and applies the necessary changes to reconcile the active configuration.

-

Device

-

The physical device enclosure providing the routing and link termination for the DoubleZero network. DZDs run the DoubleZero Agent software and are configured based on data read from the Controller service.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error.
