TRON

使用 OneKey 的 TronLink 兼容 Provider 集成 TRON 区块链。通过 window.$onekey.tron 或 window.tronWeb 访问。

OneKey 提供兼容 TronLink 的 provider 和 TronWeb 集成。功能可用性取决于钱包版本和所选网络。

快速链接

Provider 检测

// OneKey injects both the provider and TronWeb instances
const provider = window.$onekey?.tron
 
// TronWeb is available globally after connection
let tronWeb = provider?.tronWeb
 
if (!provider) {
  throw new Error('OneKey TRON provider not detected')
}
 
// Check if it's TronLink compatible
console.log('isTronLink:', provider.isTronLink) // true

快速开始

请求账户

// Request connection
const result = await provider.request({
  method: 'tron_requestAccounts'
})
 
if (result.code === 200) {
  tronWeb = provider.tronWeb
  if (!tronWeb) throw new Error('OneKey TronWeb is not ready')
  console.log('Connected!')
  const address = tronWeb.defaultAddress.base58
  console.log('Address:', address)
} else {
  console.log('Connection rejected:', result.message)
}

检查连接状态

// Check if TronWeb is ready
if (provider.ready && tronWeb && tronWeb.defaultAddress.base58) {
  console.log('Connected:', tronWeb.defaultAddress.base58)
} else {
  console.log('Not connected')
}

使用 TronWeb

连接后使用 provider.tronWeb，确保请求仍发送给 OneKey：

获取余额

const balance = await tronWeb.trx.getBalance(tronWeb.defaultAddress.base58)
console.log('Balance:', tronWeb.fromSun(balance), 'TRX')

发送 TRX

const tx = await tronWeb.trx.sendTransaction(
  'TRecipientAddress...',
  tronWeb.toSun(10) // 10 TRX
)
 
console.log('Transaction:', tx.txid)

发送 TRC20 代币

const contractAddress = 'TTokenContractAddress...'
const contract = await tronWeb.contract().at(contractAddress)
 
// Get decimals
const decimals = await contract.decimals().call()
 
// Transfer tokens
const amount = (100n * 10n ** BigInt(decimals.toString())).toString() // 100 tokens, exact integer
const tx = await contract.transfer(
  'TRecipientAddress...',
  amount
).send()
 
console.log('Transaction:', tx)

交易

签名交易

签名交易但不广播：

// 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)

智能合约交互

// Call contract method
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,
})

触发智能合约

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)

消息签名

签名消息 V1（十六进制）

签名十六进制编码的消息：

const message = tronWeb.toHex('Hello TRON!')
const signature = await provider.signMessage(message)
 
console.log('Signature:', signature)

签名消息 V2（UTF-8）

直接签名 UTF-8 消息：

const message = 'Hello TRON!'
const signature = await provider.signMessageV2(message)
 
console.log('Signature:', signature)

验证签名

const message = 'Hello TRON!'
const signature = await provider.signMessageV2(message)
 
// Verify using TronWeb
const address = await tronWeb.trx.verifyMessageV2(message, signature)
console.log('Signer:', address)

事件处理

监听账户变化

provider.on('accountsChanged', (accounts) => {
  if (accounts[0]) {
    console.log('Account changed:', accounts[0])
  } else {
    console.log('Disconnected')
  }
})

监听网络变化

provider.on('chainChanged', (chainId) => {
  console.log('Network changed:', chainId)
  // Recommend page reload for network changes
})
// Listen for TronLink initialization
window.addEventListener('tronLink#initialized', () => {
  console.log('TronLink initialized')
})
 
// Listen for messages
window.addEventListener('message', (event) => {
  if (event.source === window && event.data?.isTronLink && event.data?.message) {
    const { action, data } = event.data.message
    console.log('TronLink event:', action, data)
  }
})

API 参考

Provider 方法

方法说明
request({ method, params })通用 JSON-RPC 请求
sign(transaction)签名交易
signMessage(hexMessage)签名十六进制消息（V1）
signMessageV2(message)签名 UTF-8 消息（V2）

Request 方法

方法说明
tron_requestAccounts请求连接
tron_getProviderState获取 provider 状态
tron_signTransaction签名交易
signMessageV1签名消息 V1
signMessageV2签名消息 V2

响应码

调用 tron_requestAccounts 后，应检查成功返回的响应中的 code。当前 provider 在已有待处理请求时返回 4001，在没有返回账户或请求失败时返回 4000。这些代码的含义与 Ethereum JSON-RPC 错误码不同。

错误码说明
200成功
4000用户拒绝
4001请求排队中

事件

事件说明
accountsChanged账户已变更
chainChanged网络已变更
connect已连接
disconnect已断开连接

使用 SunWeb

用于 DappChain（侧链）操作：

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
)

错误处理

try {
  const result = await provider.request({
    method: 'tron_requestAccounts'
  })
 
  if (result.code === 4001) {
    console.log('A connection request is already pending')
  } else if (result.code !== 200) {
    console.log('Connection was not approved:', result.message)
  }
} catch (error) {
  console.error('Request failed:', error)
}

OneKey 兼容 TronLink。更新你的检测逻辑：

// Before (TronLink only)
const tronWeb = window.tronWeb
 
// After (OneKey with TronLink fallback)
const provider = window.$onekey?.tron || window.tronLink
const tronWeb = window.tronWeb // Compatibility global; verify which wallet owns it
