The eth_getProof method returns the account and storage values of the specified account including the Merkle proof on the Optimism network. This method provides cryptographic proofs that can verify account balances, nonces, and storage values without needing to trust the RPC provider. It's essential for light clients, cross-chain bridges, and any application requiring trustless verification of Optimism state.

Parameters

parameter	type	description
address	string (required)	The address to get proof for (20 bytes)
storageKeys	array (required)	Array of storage key positions to get proofs for
blockParameter	string (required)	Block number in hex or tag (latest, earliest, pending)

Return Object

Returns account proof and storage proofs with Merkle tree data. Includes address, balance, code hash, nonce, storage hash, account proof array, and storage proof objects.
