  • wallet_sendPreparedCalls now returns validUntil for calls using a Gas Sponsorship policy, so you can see when sponsorship expires at submission time.
  • wallet_getCallsStatus now checks a narrower block range for older calls and has lower latency on several chains, reducing unnecessary “not found” responses when tracking call status.
  • Fixed incorrect ERC-20 gas-payment rates returned by wallet_prepareCalls for EntryPoint v0.6, helping ensure accurate sponsorship estimates.
  • Added preliminary Glamsterdam support for the Ethereum Sepolia Bundler, so teams can begin testing compatibility ahead of the upgrade. Learn more about the Bundler.

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.

Networks

  • Arc Mainnet is live on Alchemy with full RPC coverage across all Alchemy Node APIs.

Wallet APIs

  • Fixed a bug in ERC-20 gas sponsorship where tokens with many decimal places could have sponsorship incorrectly rejected.

Paymaster

  • Added a new option to allow getting paymaster stub data for ERC-20 sponsored transactions where the sender acquires the ERC-20 payment token in the same transaction.

Rundler
