# delegateResource <TitleWithCodeLink2 link="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)

**Note:**
In versions before 6.x, most methods support variable parameter length. For example, the following codes are both valid:
```js
// Normally the third parameter is 'fromAddress', and the forth is options.
await tronWeb.transactionBuilder.delegateResource(10e6, 'toAddress', 'BANDWIDTH', 'fromAddress', false, 0, { permissionId: 2 });

// If the third parameter is object, it will be treated as options and fromAddress will be tronWeb.defaultAddress.
await tronWeb.transactionBuilder.delegateResource(10e6, 'toAddress', 'BANDWIDTH', 'fromAddress', false, { permissionId: 2 });
```

In v6.x, we do **not** support ignoring some of the arguments between required arguments and object arguments such as `options` with `permissioinId`.

## 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`    |
| address         | Owner address (base58 or hex)                                            | String                     |
| 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                    |
| options         | The permission id, optional, for multi-signature and block header for contract block header info.                      | `{ permissionId: number, blockHeader: ... }` |

## Returns

Unsigned transaction object.

## Example

```javascript
const transaction = await tronWeb.transactionBuilder.delegateResource(10e6, 'receiverAddress', 'BANDWIDTH', 'TMVQGm1qAQYVdetCeGRRkTWYYrLXuHK2HC', true, 86400);
