Parameter Description

Parameter	Type	Description
Address	String	A 20-byte string of the storage address from which the bytecode will be obtained.
Storage keys	Array	An array of 32-byte storage keys to be proofed and included.
Block number	String	A hexadecimal block number, or the string (earliest, latest, or pending).

Return Value

address: the address related to the account.
accountProof: an array of RLP-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
balance: a hexadecimal value 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.
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.
