Optimism JSON-RPC API

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

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
