Returns unsigned transaction containing the voting operation. Transaction must be signed and broadcast.

Response Fields​

Important Notes​

Voting Rules​

  1. Voting Power: 1 frozen TRX = 1 vote
  2. Vote Distribution: Can split votes among multiple SRs
  3. Vote Persistence: Votes remain until changed or TRX unfrozen
  4. Immediate Effect: Votes count immediately after confirmation
  5. Rewards: Voting rewards distributed daily based on SR performance

Implementation Examples​

// Vote for single SR
const response = await fetch('https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/wallet/votewitnessaccount', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    owner_address: 'TVoterAddress...',
    votes: [
      {
        vote_address: 'TSRAddress...',
        vote_count: 1000000  // 1M votes
      }
    ],
    visible: true
  }),
});

const transaction = await response.json();
console.log('Vote transaction created:', transaction.txID);

// Vote for multiple SRs
const multiVoteResponse = await fetch('https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/wallet/votewitnessaccount', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    owner_address: 'TVoterAddress...',
    votes: [
      {
        vote_address: 'TSR1Address...',
        vote_count: 500000
      },
      {
        vote_address: 'TSR2Address...',
        vote_count: 300000
      },
      {
        vote_address: 'TSR3Address...',
        vote_count: 200000
      }
    ],
    visible: true
  }),
});

const multiVoteTx = await multiVoteResponse.json();
console.log('Multi-vote transaction:', multiVoteTx.txID);

// Clear all votes (vote with empty array)
const clearVotesResponse = await fetch('https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/wallet/votewitnessaccount', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    owner_address: 'TVoterAddress...',
    votes: [],
    visible: true
  }),
});

Voting Strategies​

class VotingStrategy {
  constructor(apiKey) {
    this.apiKey = apiKey;
    this.baseUrl = `https://api-tron-mainnet.n.dwellir.com/${apiKey}`;
  }

  // Get available voting power

  }

  // Calculate optimal vote distribution

Best Practices​

1. Research Before Voting​

  • Check SR reliability (>99.5% uptime)
  • Review SR contributions to ecosystem
  • Verify reward distribution policies

2. Vote Management​

  • Regularly review and update votes
  • Monitor SR performance changes
  • Rebalance votes based on performance

3. Security​

  • Use multi-signature for large voting accounts
  • Verify SR addresses before voting
  • Keep voting transactions records

4. Optimization​

  • Diversify votes across multiple reliable SRs
  • Consider both rewards and network health
  • Participate in governance discussions

Common Errors​

ErrorDescriptionSolution
Insufficient frozen balanceNot enough voting powerFreeze more TRX first
Invalid witness addressSR address not foundVerify SR address from listwitnesses
Total votes exceed frozen balanceVotes > available powerReduce total vote count
Contract validate errorInvalid transaction formatCheck parameter structure

Use Cases​

  • Governance Participation: Vote for network validators
  • Reward Earning: Earn passive income from voting
  • SR Support: Support specific Super Representatives
  • Network Decentralization: Distribute voting power
  • Strategic Voting: Optimize rewards through vote management
