We want to freeze the available balance on Tron Blockchain account: this involves first getting available balance using TronWeb NodeJs Library, and then build a transaction using the Transaction Builder, sign the Transaction, and finally broadcast it.
You can get a Free API Key on TronGrid. And you can install the tronweb library using npm.
See following NodeJs code that freeze available balance (aka Stake TRX) on the given Tron wallet – you can do this anytime. The voting round is 6 hours on TRON blockchain.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | const TrxAccount = "Tron Account"; const AppKey = 'Tron-Grid-App-Key' const privateKey = 'Private Key'; const TronWeb = require('tronweb'); const tronWeb = new TronWeb({ fullHost: 'https://api.trongrid.io', headers: { "TRON-PRO-API-KEY": AppKey }, privateKey: privateKey, }); function getBalance(acc) { return new Promise((resolve, reject) => { tronWeb.trx.getBalance(acc).then(result => { resolve(result); }) }); } (async function() { const sun = await(getBalance(TrxAccount)); const trx = tronWeb.fromSun(sun); console.log("Balance of SUN = " + sun + " or " + trx + " TRX"); if (trx >= 1) { const trans = await tronWeb.transactionBuilder.freezeBalance(sun, 3, "ENERGY", TrxAccount, TrxAccount, 1); const signedtxn = await tronWeb.trx.sign(trans, privateKey); const receipt = await tronWeb.trx.sendRawTransaction(signedtxn); console.log(receipt); console.log(trx + " TRX frozon!"); } else { console.log("Not enough to Freeze!") } })(); |
const TrxAccount = "Tron Account"; const AppKey = 'Tron-Grid-App-Key' const privateKey = 'Private Key'; const TronWeb = require('tronweb'); const tronWeb = new TronWeb({ fullHost: 'https://api.trongrid.io', headers: { "TRON-PRO-API-KEY": AppKey }, privateKey: privateKey, }); function getBalance(acc) { return new Promise((resolve, reject) => { tronWeb.trx.getBalance(acc).then(result => { resolve(result); }) }); } (async function() { const sun = await(getBalance(TrxAccount)); const trx = tronWeb.fromSun(sun); console.log("Balance of SUN = " + sun + " or " + trx + " TRX"); if (trx >= 1) { const trans = await tronWeb.transactionBuilder.freezeBalance(sun, 3, "ENERGY", TrxAccount, TrxAccount, 1); const signedtxn = await tronWeb.trx.sign(trans, privateKey); const receipt = await tronWeb.trx.sendRawTransaction(signedtxn); console.log(receipt); console.log(trx + " TRX frozon!"); } else { console.log("Not enough to Freeze!") } })();
The balance is in the unit of SUN – which you can convert to TRX using tronWeb.fromSun. And the amount needs to be at last 1 TRX to freeze.
Example output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | Balance of SUN = 12301995 or 12.301995 TRX { result: true, txid: '77c74b7e76XXXXXXXXXXXXe0f6829b74ed', transaction: { visible: false, txID: '77c74b7e76cXXXXXXXXXXXXXXXXXXXXXXXXd0656e0f6829b74ed', raw_data: { contract: [Array], ref_block_bytes: '356b', ref_block_hash: '5aad1c587783fe84', expiration: 1623501405000, timestamp: 1623501348040 }, raw_data_hex: '0a0235XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX2caadc4d984697cf6dd3d483dc9fcce310abedee051803500170c8b9e281a02f', signature: [ '5316c2f0XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXbcb8f366184d135dda4c01' ] } } 12.301995 TRX frozon! |

Stake TRX (Freeze), and then Upvote the SR (Super Representatives) aka the Witnesses/Miners on Tron Blockchain, and then claim the rewards once every 24 hours. And with the earned TRX, you can invest and stake again to earn more.
