Transactions

Send transactions on TRON using OneKey

Learn how to sign and send transactions on TRON.

---

Sign Transaction

Sign a transaction without broadcasting:

// Build transaction
const tx = await tronWeb.transactionBuilder.sendTrx(
  'TRecipientAddress...',
  tronWeb.toSun(10),
  tronWeb.defaultAddress.base58
)

// Sign via provider
const signedTx = await provider.sign(tx)

console.log('Signed transaction:', signedTx)

// Broadcast manually
const result = await tronWeb.trx.sendRawTransaction(signedTx)

---

Smart Contract Interaction

const contract = await tronWeb.contract().at(contractAddress)

// Read (view function)
const result = await contract.someViewFunction().call()

// Write (requires signing)
const tx = await contract.someWriteFunction(param1, param2).send({
  feeLimit: 100_000_000, // 100 TRX
  callValue: 0,
})

---

Trigger Smart Contract

const tx = await tronWeb.transactionBuilder.triggerSmartContract(
  contractAddress,
  'transfer(address,uint256)',
  { feeLimit: 100_000_000 },
  [
    { type: 'address', value: recipientAddress },
    { type: 'uint256', value: amount }
  ],
  tronWeb.defaultAddress.base58
)

const signedTx = await provider.sign(tx.transaction)
const result = await tronWeb.trx.sendRawTransaction(signedTx)

Using SunWeb

For DappChain (side chain) operations:

const sunWeb = window.sunWeb

// Main chain to side chain
await sunWeb.depositTrx(
  amount,
  depositFee,
  feeLimit
)

// Side chain to main chain
await sunWeb.withdrawTrx(
  amount,
  withdrawFee,
  feeLimit
)
