Staking V2 Guide

TRON's Stake 2.0 (V2) system replaces the legacy Stake 1.0 model, providing more flexibility for resource management and delegation. This guide covers all V2 staking operations available in TronWeb.

tip

Stake 2.0 was introduced in JAVA-TRON v4.7.0.1. All new staking operations should use V2 methods. V1 methods (freezeBalance/unfreezeBalance) are deprecated.

Overview

Feature	Stake 1.0 (V1)	Stake 2.0 (V2)
Stake	freezeBalance	freezeBalanceV2
Unstake	unfreezeBalance	unfreezeBalanceV2 + withdrawExpireUnfreeze
Cancel Stake	N/A	cancelUnfreezeBalanceV2
Resource Delegation	Built into stake	Separate delegateResource
Flexibility	All-or-nothing	Partial stake/unstake

Stake TRX

Stake TRX to obtain BANDWIDTH or ENERGY resources.

const tx = await tronWeb.transactionBuilder.freezeBalanceV2(
    1000000000, // amount in SUN (1000 TRX)
    'ENERGY',   // resource type: 'BANDWIDTH' or 'ENERGY'
);
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Parameters:

Parameter	Type	Default	Description
amount	number	0	Amount of TRX to stake, in SUN
resource	string	'BANDWIDTH'	Resource type: 'BANDWIDTH' or 'ENERGY'
address	string	Default address	Owner address
options	object	{}	Transaction options (e.g., { permissionId })

Unstake TRX

Unstake TRX in two steps:

Step 1: Initiate Unstaking

// Start the unstaking process (14-day waiting period)
const tx = await tronWeb.transactionBuilder.unfreezeBalanceV2(
    500000000,  // amount in SUN (500 TRX)
    'ENERGY',   // resource type
);
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Step 2: Withdraw After Waiting Period

After the 14-day waiting period, withdraw the unfrozen TRX:

const tx = await tronWeb.transactionBuilder.withdrawExpireUnfreeze();
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Cancel Unstaking

Cancel a pending unstaking operation before the waiting period expires:

const tx = await tronWeb.transactionBuilder.cancelUnfreezeBalanceV2();
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Resource Delegation

Delegate your frozen resources (bandwidth or energy) to another account.

Delegate Resources

const tx = await tronWeb.transactionBuilder.delegateResource(
    1000000000,     // amount in SUN
    'TReceiverAddr', // receiver address
    'ENERGY',        // resource type
    'TOwnerAddr',    // owner address (optional)
    false,           // lock delegation (optional)
    0,               // lock period (optional)
);
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Parameters:

Parameter	Type	Default	Description
amount	number	0	Amount to delegate, in SUN
receiverAddress	string	-	Receiver's address
resource	string	'BANDWIDTH'	Resource type
address	string	Default address	Owner address
lock	boolean	false	Whether to lock the delegation
lockPeriod	number	-	Lock period in blocks (optional)
options	object	{}	Transaction options

caution

The receiver address must be different from the owner address.

Undelegate Resources

const tx = await tronWeb.transactionBuilder.undelegateResource(
    500000000,       // amount in SUN
    'TReceiverAddr', // address to undelegate from
    'ENERGY',        // resource type
);
const signedTx = await tronWeb.trx.sign(tx);
const receipt = await tronWeb.trx.sendRawTransaction(signedTx);

Query Delegation Info

Get Delegated Resources

// Get delegation details between two addresses
const result = await tronWeb.trx.getDelegatedResourceV2(fromAddress, toAddress);
console.log(result.delegatedResource);
// [{
//   from: 'address',
//   to: 'address',
//   frozen_balance_for_bandwidth: 0,
//   frozen_balance_for_energy: 1000000000,
//   ...
// }]

const result = await tronWeb.trx.getDelegatedResourceAccountIndexV2(address);
console.log(result.fromAccounts); // Accounts that delegated to this address
console.log(result.toAccounts);   // Accounts this address delegated to

Get Maximum Delegatable Amount

const result = await tronWeb.trx.getCanDelegatedMaxSize(address, 'ENERGY');
console.log(result.max_size); // Maximum amount that can be delegated

Get Withdrawable Amount

// Check how much TRX can be withdrawn after unstaking
const result = await tronWeb.trx.getCanWithdrawUnfreezeAmount(address);
console.log(result.amount); // Amount available for withdrawal

Get Available Unfreeze Count

// Check remaining unstaking slots
const result = await tronWeb.trx.getAvailableUnfreezeCount(address);
console.log(result.count); // Remaining unstaking times

);
const signedUndelegate = await tronWeb.trx.sign(undelegateTx);
await tronWeb.trx.sendRawTransaction(signedUndelegate);

// 5. Start unstaking (14-day waiting period begins)
const unstakedTx = await tronWeb.transactionBuilder.unfreezeBalanceV2(
    1000_000_000, 'ENERGY'
);
const signedUnstaked = await tronWeb.trx.sign(unstakedTx);
await tronWeb.trx.sendRawTransaction(signedUnstaked);

// 6. After 14 days, withdraw unfrozen TRX
const withdrawTx = await tronWeb.transactionBuilder.withdrawExpireUnfreeze();
