# eth\_getProof - Mantle

Example code for the eth\_getProof JSON-RPC method. Complete guide on how to use eth\_getProof JSON-RPC in GetBlock Web3 documentation.

This method returns the account and storage values of the specified account including the Merkle proof. This is useful for verifying state without trusting the RPC provider.

### Parameters

| Parameter   | Type   | Description                    |
| ----------- | ------ | ------------------------------ |
| address     | string | The address of the account     |
| storageKeys | array  | Array of storage keys to prove |
| blockNumber | string | Block number (hex) or tag      |
