The Ropsten, Kovan and Rinkeby networks on Ethereum will no longer be supported on Alchemy. All requests to those networks after this date will return HTTP 410 errors. We strongly recommend switching over to Goerli as soon as possible. Here is a short guide on how to migrate.
Removing support for unprotected transactions that do not adhere to the EIP 155. Please make any necessary code changes ahead of time to protect your transactions from replay attacks by including the
chainId field in your transaction payload.
Optimism Kovan will be deprecated in favor of Optimism Goerli. We recommend migrating your applications from Optimism Kovan to Optimism Goerli ASAP.
order parameter to alchemy_getAssetTransfers.
Added support for Arbitrum and Optimism in alchemy_getAssetTransfers.
tokenType field on the getContractMetadata method will switch capitalization from
"ERC1155". Please prepare ahead of time for this change by setting up your code to accept either capitalization formats.
At 9am PST we will begin to enforce HTTPS requests. This means if you send requests using HTTP it will return a
301 status code, and we will redirect you to the HTTPS version of that respective endpoint.
[API] Removed support for Debug API methods, including debug_TraceTransaction. Please use Trace API Endpoints instead.
Arbitrum Rinkeby will be replaced in favor of Arbitrum Goerli sometime in Q3 2022 following the Eth-Rinkeby deprecation target date. We encourage you to migrate over to Goerli as soon as possible.
