Autovault setup configured roles, adapters, fees, and abdications without minting dead shares. It could also permanently retain an active exit gate when resuming setup. This adds the vault-level seed required by Morpho's guidance and clears exit gates before disabling their setters.

Setup now reads the underlying token's decimals on-chain and mints max(1e9, 10^(6 + max(0, 18 - decimals))) raw shares to 0x000000000000000000000000000000000000dEaD. The review screen shows the permanently locked amount: 1 USDC for 6 decimals, 0.01 BTC for 8 decimals, or 0.000000001 WETH for 18 decimals.

  • Read supply, assets, and dead shares from one fresh block. Already-seeded vaults skip minting; funded vaults without sufficient dead shares require review.
  • Check the expected initial price and wallet balance, reset mismatched nonzero allowances, approve exactly the seed amount, then recheck state and confirmed allowance. This bounds spending because mint has no maxAssets argument.
  • Clear nonzero exit gates before minting or abdication. Reject already-abdicated nonzero gates and failed gate reads before approval. Setup status requires verified zero gates as well as abdications and dead shares.
  • Keep gate resets, seed, and remaining configuration in one simulated vault multicall, with minting before adapter, rate, and fee changes. Wait for successful approval/setup receipts and refresh setup status after confirmation.

Reference comparison:

  • Found the live Base SoSoValue x Unified Labs USDC setup. Historical state and logs verify that its first deposit spent exactly 1 USDC to mint 1e18 dead shares.
  • The current curator app's extracted permanent-settings builder reproduced that transaction's calldata byte for byte. Its share and asset calculators agree with this implementation across all 256 uint8 decimal values. Website attribution remains an inference; it is not encoded on-chain.
  • Recorded the full transaction sequence, source hashes, differences, and limitations in the comparison note.

Validation:

  • node --test scripts/test-vault-dead-deposit.cjs scripts/test-vault-initialization-gates.cjs: 17 tests pass, including token decimals, exact allowances, receipt failures, price changes, concurrent deposits/seeding, active/permanent gates, failed gate reads, and completion status.
  • npx ultracite fix on changed code, repository-wide npx ultracite check, pnpm typecheck, and git diff --check: pass.
  • Local Anvil Base fork from block 51,115,579: execute the production initialization callback against the configured deployed Vault V2 factory, adapter factory, and registry with 6-, 8-, and 18-decimal mock tokens. Verify exact seed/spend, consumed allowances, linked adapters, receipts, resumed setup, and rejection of funded unseeded vaults. Also verify all three active exit gates are cleared before minting and permanently configured nonzero gates are rejected before approval. Wallet/React hooks use local RPC bindings; no public-chain transactions were broadcast.
  • Root cause of the gate issue: abdication checked permission removal without checking the retained gate value. Earlier tests covered fresh factory defaults, where gates were already zero. Added an explicit resumed-gate validation rule and regression cases in docs/VALIDATIONS.md and the gate test script.
  • Applied Universal Validation, Bug Fixes, Consolidation Pass, React And TypeScript, Async And Errors, Data And Domain Flows, Transactions And Wallet Flows, and UI And Accessibility rules. Checked setup-status consumers and the setup modal. Browser wallet prompts were not exercised.

Remaining boundaries:

  • Deployment remains separate from initialization, as in the current curator app. Fresh checks and exact allowance do not atomically enforce that the seed is first: another deposit can land after the final check during signing/mining. Closing this window requires atomic deployment/seeding or an on-chain deposit gate.
  • Current dead-share presence does not prove the seed was historically first. Existing funded vaults require a separate historical/share-price review; this does not establish that an attack occurred or retroactively repair them.
  • Underlying market and Vault V1 dead-share requirements remain separate. The live fork checks cover Base, not Robinhood.

Summary by CodeRabbit

  • New Features

    • Vault V2 initialization now verifies and, when needed, seeds the required dead shares before setup can be completed.
    • Added clear initialization progress, approval, completion, and error states, including retry options for verification failures.
    • Initialization status now identifies missing dead-share seeding as a setup requirement.
  • Bug Fixes

    • Prevents setup for vaults that already contain deposits without the required dead-share protection.
    • Added safeguards for insufficient balances, approval changes, transaction failures, and race conditions during initialization.
    • Added coverage for assets with varying decimal formats and previously funded vaults.

📝 Walkthrough

Walkthrough

Vault V2 initialization now calculates decimal-adjusted dead-deposit seeds, validates vault and token state, waits for approval and setup receipts, and refreshes setup status. The modal reports seed state, blocks unsafe initialization, and shows retry and failure states.

Changes

Vault V2 dead-deposit initialization

Layer / File(s) Summary
Dead-deposit amounts and snapshots
src/utils/vaultV2Setup.ts, src/data-sources/rpc/vault-dead-deposit.ts
Defines seed amounts and the dead-deposit receiver. Fetches vault state at a consistent block. Rejects non-empty unseeded vaults.
Approval and mint preparation
src/hooks/vault-dead-deposit.ts, scripts/test-vault-dead-deposit.cjs, docs/VALIDATIONS.md
Validates balances, allowances, preview prices, and state changes. Resets allowances when required. Encodes the mint call only after approval confirmation.
Dead-deposit query and setup status
src/hooks/queries/useVaultV2DeadDepositQuery.ts, src/hooks/useVaultV2InitializationStatus.ts, src/hooks/useVaultQueryRefresh.ts
Adds dead-deposit query state to setup requirements, loading, errors, completion, and refresh handling.
Guarded initialization execution
src/hooks/useVaultV2.ts
Prepares seed calls, builds required setup calls, simulates and submits the final multicall, waits for receipts, tracks progress, and clears failure state.
Initialization review and completion UI
src/features/autovault/components/vault-detail/modals/vault-initialization-modal.tsx
Displays seed status and cost. Blocks completion for unsafe existing deposits. Adds retry, approval, completion, and initialization error states.

A transient refresh failure after initialization can hide retry state and leave setup status stale, though the confirmed transaction remains unaffected.

🌐 Web query:

For TanStack Query React v5.69.0, confirm that refetch()without{ throwOnError: true } resolves query failures as an error result rather than rejecting.

💡 Result:

In TanStack Query React v5.69.0, calling refetch without setting throwOnError: true will resolve the promise with the query result rather than rejecting it [1][2]. The official documentation explicitly states that the refetch function returns a promise that resolves when the refetch completes [1][2]. By default, if the query encounters an error during the refetch, the error is swallowed (logged) and not surfaced to the caller as a rejection [3][1][2]. To change this behavior and force the promise to reject when an error occurs, you must explicitly pass { throwOnError: true } to the refetch call [1][2].

Propagate setup-refresh failures.

All three refetch() calls resolve with error results by default. handleCompleteInitialization then closes the modal when refetchSetupStatus() resolves. A failed refresh can bypass the retry state. Pass { throwOnError: true } to each call, or throw when a result contains an error.
