eth_getProof

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

getProof-Parameters

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

Example Parameters

params: ["0x1234567890123456789012345678901234567890",["0x0000000000000000000000000000000000000000000000000000000000000000","0x0000000000000000000000000000000000000000000000000000000000000001"],"latest"]

getProof-Returns

Returns Object - A account object:

balance: QUANTITY - the balance of the account. See eth_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. See eth_getTransactionCount

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.
