This section is describing the supported Optimism RPC method calls.
Optimism is a layer-2 rollup scaling solution with single-round fault proofs that is EVM-compatible.
The Optimism network submits faster and cheaper transactions to Ethereum.
All the examples in this section use an Ethereum endpoint. Make sure you replace it with your Optimism endpoint (https://optimism-mainnet.blastapi.io/<project-id>) or (https://optimism-goerli.blastapi.io/<project-id>) when issuing the RPC calls:
