eth_getProof - Ethereum

GET https://eth-mainnet.unifra.io/v1/{your-api-key}

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

• DATA, 20 Bytes - Address of the account.
• ARRAY, 32 Bytes - Array of storage-keys which should be proofed and included. See eth_getStorageAt
• 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. 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.
