## Wallets

**Wallet APIs**

* Added support for Arc Mainnet across the Wallet APIs stack, including the bundler (Rundler) and Paymaster. You can now create smart accounts, sponsor gas, and send user operations on Arc alongside every other supported network.
* Enabled EIP-7702 on ApeChain Mainnet. Wallet APIs and the bundler now support 7702 smart accounts on ApeChain.
* The `@alchemy/wallet-apis` SDK now recognizes the SemiModularAccount7702 v1.1.0 delegate address (`0x77021100bD87b7008E5E1989d0eB38555d0d0000`). New 7702 accounts created through Wallet APIs default to v1.1.0; existing v1.0.0 accounts keep their current delegate. See [choosing your delegation version](https://www.alchemy.com/docs/wallets/transactions/using-eip-7702#choose-the-delegation-version).
