eth_getProof

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

For Growth and Custom service plans

This JSON-RPC method allows a request to be forwarded to a partner service provider if Infura should experience a service issue or outage. See Failover protection and Enable API request forwarding for complete details.

If you would like failover protection but don't qualify under your current plan, then either self-upgrade to the Growth plan or contact a sales representative to upgrade to a Custom plan.

Parameters​

  • address: A string representing the address (20 bytes) to check for balance.
  • storageKeys: An array of 32-byte storage keys to be proofed and included.
  • blockParameter: A hexadecimal block number, or one of the string tags latest, earliest, pending, safe, or finalized. See the default block parameter.

Returns​

  • balance: Hexadecimal 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.
  • accountProof: An array of RLP-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
  • 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.

Example​

Replace YOUR-API-KEY with an API key from your Infura dashboard.
