delegateResource <src>

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:

// 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

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

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