zkLink Nova chain RPC Methods & API Documentation

eth_getProof RPC Method

The eth_getProof is used to retrieve the account and storage values with a Merkle proof for a specific account at a specific block. The Merkle proof contains a set of intermediate hashes that can be used to verify that a specific account exists on the Ethereum blockchain at a specific block, and that the account has a specific state (i.e., a specific balance or nonce value).

Parameters

address - String - The address of the account to retrieve the Merkle proof for.
storageKeys - Array [Strings] - An array of storage keys to retrieve the values for. Each storage key should be a string that represents the position of the storage value within the account's storage trie.
blockNumber - Block number as hexadecimal or Tag (String) "latest", "earliest""pending".

Returns

address - String - The address of the account that the proof is for.
accountProof - Array - An array of rlp-serialized MerkleTree-Nodes which starts with the stateRoot-Node and follows the path of the SHA3 address as key.
balance - The current balance of the account in wei.
codeHash - 32 Bytes - A hash of the code of the account.
nonce - Nonce value of the account.
storageProof - Array of storage-entries. Each entry has these properties:
- key - The requested storage key
- value - The storage value.
- proof - Array of rlp-serialized MerkleTree-Nodes, starting with the storageHash-Node, following the path of the SHA3 (key) as path.
