# delegateResource

After staking and obtaining resources, resources can be delegated to multiple recipients through this interface. The optional `lock` parameter can specify whether the delegation can be revoked within 3 days. (v5.1.0 new interface)

## Usage

```javascript
tronWeb.transactionBuilder.delegateResource(amount, receiverAddress, resource, address, lock, lockPeriod, options);
```

## Parameters

| Argument      |  Description| Type    |
| --------------- | ------------- | -------------------------- |
| amount          | The amount of assets in `sun` to be delegated, larger than 0    | Integer  |
| receiverAddress | The account address of receiving delegation (base58 or hex)    | String                     |
| resource        | Asset type to be delegated. Optional, the default is `BANDWIDTH`.   | `BANDWIDTH` or `ENERGY`    |

| lock            | If the `lock` is `true`, delegation can not be revoked within 3 days. The default is `false`  | Boolean  |
| lockPeriod      | When `lock` is `true`, this parameter will set the lock time, with the unit of blocks. And the new resource delegating to the same address of same type should have this `lockPeriod` value larger than the lockup blocks left of the address. | Integer                    |
