wallet/freezebalancev2

Resource Management V2

Dwellir's TRON infrastructure supports the latest Stake 2.0 mechanism for efficient resource management. Stake TRX to get bandwidth/energy while earning rewards and voting rights.

Start staking TRX →

Freeze (stake) TRX balance to obtain bandwidth or energy resources using the Stake 2.0 mechanism. Staked TRX earns rewards and provides voting power for Super Representatives.

Use Cases

wallet/freezebalancev2 is essential for:

• Resource Acquisition - Get bandwidth for transactions
• Energy Generation - Power smart contract interactions
• Reward Earning - Earn staking rewards (~4-7% APR)
• Governance Participation - Gain voting power for SRs
• DApp Operations - Ensure smooth contract execution

Parameters

Parameter	Type	Required	Description
owner_address	string	Yes	Address staking TRX (Base58 or Hex)
frozen_balance	number	Yes	Amount to stake in SUN (1 TRX = 1,000,000 SUN)
resource	string	Yes	Resource type: "BANDWIDTH" or "ENERGY"
visible	boolean	No	Use Base58 format (default: true)
permission_id	number	No	Permission ID for multi-sig accounts

Request Example

{
  "owner_address": "TRX6Q82wMqWNbCCmJPLz9mR8AZwqvUU2pN",
  "frozen_balance": 10000000000,
  "resource": "ENERGY",
  "visible": true
}

Response Fields

Field	Type	Description
txid	string	Transaction ID
visible	boolean	Address format used
raw_data	object	Transaction raw data
raw_data.contract	array	Contract details
raw_data.ref_block_bytes	string	Reference block bytes
raw_data.ref_block_hash	string	Reference block hash
raw_data.expiration	number	Transaction expiration time
raw_data.timestamp	number	Transaction timestamp

Common Use Cases

1. Auto-Staking System

class AutoStakingSystem {
  constructor(apiKey) {
    this.staking = new TronStakingManager(apiKey);
    this.minBalance = 1000; // Minimum TRX to keep unstaked
  }
  
  async autoStake(address, keepBalance = 1000) {
    // Get current balance
    const account = await this.getAccount(address);
    const availableTRX = (account.balance / 1_000_000) - keepBalance;
    
    if (availableTRX <= 0) {
      return { message: 'Insufficient balance for staking' };
    }
    
    // Split 30% bandwidth, 70% energy (typical DApp usage)
    const bandwidthTRX = Math.floor(availableTRX * 0.3);
    const energyTRX = Math.floor(availableTRX * 0.7);
    
    return await this.staking.stakeForResources(
      address,
      bandwidthTRX,
      energyTRX
    );
  }
}

2. Resource Optimization

async function optimizeResources(address) {
  const resources = await getAccountResource(address);
  
  // Check utilization
  const bandwidthUtil = resources.freeNetUsed / resources.freeNetLimit;
  const energyUtil = resources.EnergyUsed / resources.EnergyLimit;
  
  const recommendations = [];
  
  if (bandwidthUtil > 0.8) {
    recommendations.push({
      action: 'STAKE',
      resource: 'BANDWIDTH',
      reason: 'High bandwidth utilization',
      suggestedTRX: 1000
    });
  }
  
  if (energyUtil > 0.8) {
    recommendations.push({
      action: 'STAKE',
      resource: 'ENERGY',
      reason: 'High energy utilization',
      suggestedTRX: 5000
    });
  }
  
  return recommendations;
}

3. Staking Pool Management

class StakingPool {
  async distributeStakes(participants, totalTRX) {
    const stakes = [];
    
    for (const participant of participants) {
      const share = (participant.contribution / 100) * totalTRX;
      
      stakes.push({
        address: participant.address,
        amount: share,
        resource: participant.preferredResource || 'ENERGY'
      });
    }
    
    return this.executeStakes(stakes);
  }
}

Resource Calculation

Resource	Rate	Usage
Bandwidth	~1,000 per TRX	Regular transactions
Energy	~280 per TRX	Smart contract calls
Voting Power	1 vote per TRX	SR voting

Staking Recommendations by Use Case

Use Case	Bandwidth (TRX)	Energy (TRX)	Total
Basic Wallet	100	0	100
DeFi User	500	5,000	5,500
DApp Developer	1,000	20,000	21,000
Exchange	10,000	50,000	60,000

Error Handling

Error Code	Description	Solution
INVALID_RESOURCE	Invalid resource type	Use "BANDWIDTH" or "ENERGY"
INSUFFICIENT_BALANCE	Not enough TRX	Check balance before staking
ACCOUNT_NOT_FOUND	Address doesn't exist	Verify address validity
TAPOS_ERROR	Transaction expired	Recreate with fresh block reference

async function safeStake(address, amount, resource) {
  try {
    // Check balance first
    const account = await getAccount(address);
    const balance = account.balance / 1_000_000;
    
    if (balance < amount) {
      throw new Error(`Insufficient balance: ${balance} TRX available`);
    }
    
    // Validate resource type
    if (!['BANDWIDTH', 'ENERGY'].includes(resource)) {
      throw new Error(`Invalid resource: ${resource}`);
    }
    
    // Create and return transaction
    return await createFreezeTransaction(address, amount, resource);
    
  } catch (error) {
    console.error('Staking error:', error);
    return {
      success: false,
      error: error.message
    };
  }
}

Best Practices

1. Keep Reserve - Always keep 50-100 TRX unstaked for fees
2. Balance Resources - Monitor usage and adjust stakes accordingly
3. Batch Operations - Stake for both resources in one session
4. Monitor Rewards - Track staking rewards and compound regularly
5. Plan Unstaking - Remember 14-day waiting period for unstaking

Notes

• Lock Period: Staked TRX has a minimum 14-day lock period
• Rewards: Staking rewards are distributed every 6 hours
• Voting Power: Staked TRX provides voting power for Super Representatives
• Resource Recovery: Bandwidth recovers 24 hours, energy recovers based on consumption
