# eth\_getProof - Mantle

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      |

### Response Parameters

| Field        | Type   | Description                                |
| ------------ | ------ | ------------------------------------------ |
| address      | string | The address of the account                 |
| accountProof | array  | Array of RLP-serialized Merkle proof nodes |
| balance      | string | Account balance in wei (hex)               |
| codeHash     | string | Hash of the account code                   |
| nonce        | string | Account nonce (hex)                        |
| storageHash  | string | Storage root hash                          |
| storageProof | array  | Array of storage proofs                    |

### Use Case

The `eth_getProof` method is essential for:

* Light client verification
* Trustless state validation
* Cross-chain bridges
* State proof verification
* Decentralized applications requiring proof

### Error Handling

| Status Code | Error Message  | Cause                           |
| ----------- | -------------- | ------------------------------- |
| 403         | Forbidden      | Missing or invalid ACCESS-TOKEN |
| -32602      | Invalid params | Invalid address or storage keys |
