Getting Started
Learn how to detect, connect, and interact with TRON using OneKey’s provider.
OneKey’s TRON provider is fully compatible with TronLink, including TronWeb and SunWeb instances.
Provider Detection
// OneKey injects both the provider and TronWeb instances
const provider = window.$onekey?.tron
// TronWeb is available globally after connection
const tronWeb = window.tronWeb
if (!provider) {
throw new Error('OneKey TRON provider not detected')
}
// Check if it's TronLink compatible
console.log('isTronLink:', provider.isTronLink) // trueRequest Accounts
// Request connection
const result = await provider.request({
method: 'tron_requestAccounts'
})
if (result.code === 200) {
console.log('Connected!')
const address = tronWeb.defaultAddress.base58
console.log('Address:', address)
} else {
console.log('Connection rejected:', result.message)
}Check Connection Status
// Check if TronWeb is ready
if (tronWeb && tronWeb.ready) {
console.log('Connected:', tronWeb.defaultAddress.base58)
} else {
console.log('Not connected')
}Using TronWeb
After connection, TronWeb instance is available globally:
Get Balance
const balance = await tronWeb.trx.getBalance(tronWeb.defaultAddress.base58)
console.log('Balance:', tronWeb.fromSun(balance), 'TRX')Send TRX
const tx = await tronWeb.trx.sendTransaction(
'TRecipientAddress...',
tronWeb.toSun(10) // 10 TRX
)
console.log('Transaction:', tx.txid)Send TRC20 Token
const contractAddress = 'TTokenContractAddress...'
const contract = await tronWeb.contract().at(contractAddress)
// Get decimals
const decimals = await contract.decimals().call()
// Transfer tokens
const amount = 100 * (10 ** decimals) // 100 tokens
const tx = await contract.transfer(
'TRecipientAddress...',
amount
).send()
console.log('Transaction:', tx)Event Handling
Listen for Account Changes
provider.on('accountsChanged', (accounts) => {
if (accounts[0]) {
console.log('Account changed:', accounts[0])
} else {
console.log('Disconnected')
}
})Listen for Network Changes
provider.on('chainChanged', (chainId) => {
console.log('Network changed:', chainId)
// Recommend page reload for network changes
})Window Events (TronLink Compatible)
// Listen for TronLink initialization
window.addEventListener('tronLink#initialized', () => {
console.log('TronLink initialized')
})
// Listen for messages
window.addEventListener('message', (event) => {
if (event.data.isTronLink) {
const { action, data } = event.data.message
console.log('TronLink event:', action, data)
}
})Migration from TronLink
OneKey is TronLink-compatible. Update your detection logic:
// Before (TronLink only)
const tronWeb = window.tronWeb
// After (OneKey with TronLink fallback)
const provider = window.$onekey?.tron || window.tronLink
const tronWeb = window.tronWeb // Both inject thisLast updated on
