# getTokenAccountsByDelegate - Solana

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

| id        | string | Request identifier matching the request                                |
| result    | object | RPC response object where value is an array of matching token accounts |

### Value Entry

| Field   | Type   | Description                                                                 |

## Use Cases

* **Delegation Audits**: List every token account a protocol has been approved to move
* **Escrow Tracking**: Verify delegate approvals before executing a transfer
* **Revocation Flows**: Surface active delegations so a user can revoke them
* **Security Review**: Detect unexpected delegate authority on user token accounts

## Error Handling
