Wallet APIs

  • Wallet API responses now surface a clear message when a request is rate-limited because the underlying contract or account is delinquent, so you can identify the cause directly from the response.
  • User operation status lookups now reflect more recent activity, thanks to a reduced internal time buffer when checking on-chain state.
  • Robinhood Mainnet is now on the eth_getLogs unlimited block-range list, removing the default range limit for event and log queries.

Upgrades

July 16, 2026

Solana

  • Resolved an edge case in alchemy_requestFeePayer where unusual instruction data could cause an error during transaction parsing.

Upcoming deprecations

  • Botanix Mainnet and Testnet (botanix-mainnet, botanix-testnet) — Alchemy support ends on August 1, 2026. The Botanix team is shutting down both networks. See the Botanix Deprecation Notice.
  • Polygon PoS Erigon client — Polygon Labs is sunsetting the Erigon client on Polygon PoS on August 1, 2026. Alchemy is migrating Polygon Mainnet and Amoy from Erigon to Bor. After this date, the entire erigon_* namespace along with trace_filter, trace_get, and trace_rawTransaction will no longer be available on polygon-mainnet or polygon-amoy, and Bor supports eth_getProof only for the latest 128 blocks. The remaining trace_* methods (trace_block, trace_transaction, trace_call, trace_callMany, trace_replayTransaction, trace_replayBlockTransactions) will continue to be available, served by Bor. See the Polygon PoS Erigon Client Deprecation Notice for the full migration guide.
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.
