Changelog

Stay in touch with new updates and improvements in the Alchemy ecosystem.

July 9, 2026

Wallet APIs

  • wallet_sendPreparedCalls now returns a clear validation error when a call's data field is empty, instead of failing unexpectedly.
  • ERC-20 balance read failures now return a structured validation error instead of a raw contract error, making sponsorship rejections easier to diagnose.
  • The Solana paymaster now returns a clear validation error when a fee-payer transaction contains no accounts, instead of an internal error.

Alchemy CLI

  • The Alchemy CLI lets you manage your Alchemy resources from the command line, including querying your compute unit usage across summary and time-series endpoints with the new Usage API. See the CLI usage docs.

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.
