eth_getProof

Returns the account and storage values, including the Merkle proof, of the specified account.

Parameters​

  • address: A string representing the address (20 bytes) to check for balance.
  • storageKeys: An array of 32-byte storage keys to be proofed and included.
  • blockParameter: A hexadecimal block number, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.

Returns​

  • balance: Hexadecimal of the current balance in wei.
  • codeHash: The 32-byte hash of the code of the account.
  • nonce: The nonce of the account.
  • storageHash: 32 bytes. The SHA3 of the StorageRoot. All storage will deliver a Merkle proof starting with this rootHash.
  • accountProof: An array of RLP-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
  • storageProof: An array of storage-entries as requested. Each entry is an object with these properties:
    • key: The requested storage key.
    • value: The storage value.
    • proof: An array of RLP-serialized MerkleTree-Nodes, starting with the storageHash-Node, following the path of the SHA3 (key) as path.
