JSON-RPC methods

The standard Ethereum methods documented here are supported by Infura on the Optimism network. For custom Optimism methods, please see Optimism Ethereum JSON-RPC API documentation (Bedrock release).


The Optimism Bedrock migration supports different JSON-RPC methods. Refer to the Optimism Bedrock documentation for more information.

You need to be aware of the differences between the behavior of Ethereum and Optimism. For example, there are differences related to:

  • Opcodes
  • Transaction and transaction pools
  • Block time and size
