eth_getProof

Returns the account and storage values of the specified account including the Merkle-proof. This call can be used to verify that the data you are pulling from is not tampered with.​

Parameters​

  1. DATA, 20 Bytes - address of the account.
  2. ARRAY, 32 Bytes - array of storage-keys which should be proofed and included.
  3. QUANTITY|TAG - integer block number, or the string "latest" or "earliest", see the default block parameter

Returns​

Object - A account object:

  • balance: QUANTITY - the balance of the account. Seeeth_getBalance
  • codeHash: DATA, 32 Bytes - hash of the code of the account. For a simple Account without code it will return "0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470"
  • nonce: QUANTITY, - nonce of the account.
  • storageHash: DATA, 32 Bytes - SHA3 of the StorageRoot. All storage will deliver a MerkleProof starting with this rootHash.
  • accountProof: ARRAY - Array of rlp-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
  • storageProof: ARRAY - Array of storage-entries as requested. Each entry is a object with these properties:
    • key: QUANTITY - the requested storage key
    • value: QUANTITY - the storage value
    • proof: ARRAY - Array of rlp-serialized MerkleTree-Nodes, starting with the storageHash-Node, following the path of the SHA3 (key) as path.
