Conflux

使用 OneKey 的 Fluent 兼容 Provider 集成 Conflux 区块链。通过 window.$onekey.conflux 访问。

OneKey 的 Conflux Provider 同时兼容 ConfluxPortal 和 Fluent 钱包接口。

Provider 检测

// Detect OneKey Conflux provider
const provider = window.$onekey?.conflux
 
if (!provider) {
  throw new Error('OneKey Conflux provider not detected')
}
 
// Check compatibility flags
console.log('isConfluxPortal:', provider.isConfluxPortal) // true
console.log('isFluent:', provider.isFluent) // true
console.log('isOneKey:', provider.isOneKey) // true

快速开始

请求账户

const accounts = await provider.request({
  method: 'cfx_requestAccounts'
})
 
console.log('Connected:', accounts[0])

检查连接

if (provider.isConnected()) {
  const accounts = await provider.request({ method: 'cfx_accounts' })
  console.log('Accounts:', accounts)
}

账户和网络

获取链 ID

const chainId = await provider.request({ method: 'cfx_chainId' })
console.log('Chain ID:', chainId) // e.g., '0x405' for mainnet

获取网络版本

const networkId = await provider.request({ method: 'net_version' })
console.log('Network ID:', networkId) // e.g., '1029' for mainnet

获取余额

const balance = await provider.request({
  method: 'cfx_getBalance',
  params: [address, 'latest_state']
})
 
console.log('Balance:', balance) // In Drip (1 CFX = 10^18 Drip)

交易

发送交易

const txHash = await provider.request({
  method: 'cfx_sendTransaction',
  params: [{
    from: senderAddress,
    to: recipientAddress,
    value: '0xDE0B6B3A7640000', // 1 CFX in Drip (hex)
    gas: '0x5208', // 21000
  }]
})
 
console.log('Transaction hash:', txHash)

带 Gas 估算的发送

// Estimate gas first
const gasEstimate = await provider.request({
  method: 'cfx_estimateGasAndCollateral',
  params: [{
    from: senderAddress,
    to: recipientAddress,
    value: '0xDE0B6B3A7640000',
  }]
})
 
// Send with estimated values
const txHash = await provider.request({
  method: 'cfx_sendTransaction',
  params: [{
    from: senderAddress,
    to: recipientAddress,
    value: '0xDE0B6B3A7640000',
    gas: gasEstimate.gasLimit,
    storageLimit: gasEstimate.storageCollateralized,
  }]
})

调用合约

const result = await provider.request({
  method: 'cfx_call',
  params: [{
    to: contractAddress,
    data: encodedFunctionCall,
  }, 'latest_state']
})
 
console.log('Result:', result)

事件处理

监听账户变化

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

监听链变化

provider.on('chainChanged', (chainId) => {
  console.log('Chain changed:', chainId)
  // Recommend reloading the page
  window.location.reload()
})

监听连接

provider.on('connect', ({ chainId, networkId }) => {
  console.log('Connected to:', chainId, networkId)
})
 
provider.on('disconnect', () => {
  console.log('Disconnected')
})

配合 js-conflux-sdk 使用

设置

npm install js-conflux-sdk

连接 Provider

import { Conflux } from 'js-conflux-sdk'
 
const conflux = new Conflux({
  url: 'https://main.confluxrpc.com',
  networkId: 1029,
})
 
// Use OneKey provider for signing
conflux.provider = provider

使用 SDK 发送交易

// Create and send transaction
const tx = conflux.cfx.sendTransaction({
  from: senderAddress,
  to: recipientAddress,
  value: Conflux.Drip.fromCFX(1), // 1 CFX
})
 
console.log('Transaction:', tx)
 
// Wait for confirmation
const receipt = await tx.executed()
console.log('Receipt:', receipt)

合约交互

const contract = conflux.Contract({
  abi: contractABI,
  address: contractAddress,
})
 
// Read
const result = await contract.someViewFunction().call()
 
// Write
const tx = contract.someWriteFunction(param1, param2).sendTransaction({
  from: senderAddress,
})
 
const receipt = await tx.executed()

错误处理

try {
  const accounts = await provider.request({
    method: 'cfx_requestAccounts'
  })
} catch (error) {
  if (error.code === 4001) {
    console.log('User rejected the request')
  } else if (error.code === -32603) {

地址格式

Conflux 使用 base32 地址 (CIP-37)：

// Mainnet: cfx:...
// Testnet: cfxtest:...
 
// Example mainnet address
const address = 'cfx:aak2rra2njvd77ezwjvx04kkds9fzagfe6ku8scz91'
 
// Convert between formats using js-conflux-sdk
import { format } from 'js-conflux-sdk'
 
const hexAddress = format.hexAddress(address)
const base32Address = format.address(hexAddress, 1029) // networkId
