June 18, 2026
Alchemy Signer `/signup` endpoint turned off

The Alchemy Signer /signup endpoint has been turned off as of June 18, 2026. New sign-ups for the Alchemy Signer, Account Kit, and Embedded Wallets are no longer accepted and will return an error.

Login and auth endpoints remain live so existing users can continue to sign in and migrate to a new signer. For new sign-ups, use Privy with Wallet APIs. The signer migration overview covers the React and JWT / Auth0 migration flows step by step.

Wallet APIs

  • Added an option to skip the ERC-20 paymaster balance precheck for post-op gas payments when the user operation will credit the sender with the tokens needed to cover gas.
  • Made standalone sponsored delegation generally available, enabling delegation and undelegation without a user operation.
  • Expanded EIP-7702 support in Rundler to additional networks, including Zora Mainnet, Soneium Minato, Celo Sepolia, Cronos Mainnet, Edge, and more.

Upgrades

May 14, 2026

SDK

  • Improved schema validation and error handling in @alchemy/wallet-apis to make integration issues easier to diagnose.
  • Added stricter selector validation to PermissionBuilder to catch invalid permission definitions earlier.
  • Updated the SDK reference docs with complete type information.

Wallet APIs

Upgrades

May 7, 2026

  • Expanded Pharos Mainnet support to the APSE region to improve regional availability.

April 30, 2026

Updates

  • Added CPI rent prefunding support for Solana transactions in Gas Manager. Use prefundRent: true with alchemy_requestFeePayer when a sponsored transaction may create accounts through a cross-program invocation (CPI) and needs rent covered. Learn more.

Upgrades

April 16, 2026

SDK

  • SDK v5 reference docs are now live. We recommend that aa-sdk users upgrade. @alchemy/wallet-apis is the recommended package for most users, with updated lower-level packages available for integrating directly with viem.
  • Added stricter selector checks in the MAv2 permission builder.

Rundler

  • Fixed an initialization bug with flashblocks on fast block time networks (e.g., Xlayer).
