Request Parameters

• address - a string representing the address (20 bytes) to check for balance
• storageKeys - Array of 32-Byte storage keys that should be proofed and included. See eth_getStorageAt.
• blockParameter - a hexadecimal block number, or the string "latest" or "earliest"

Response

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

Result Fields

• balance: hexadecimal of the current balance in Wei.
• codeHash: 32-Byte hash of the code of the account.
• nonce: nonce of the account.
• storageHash: 32 Bytes - SHA3 of the StorageRoot. All storage will deliver a Merkle proof starting with this rootHash.
• accountProof: array of rlp-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
• storageProof: array of storage-entries as requested. Each entry is an object with 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.
