Using with js-conflux-sdk

Setup

npm install js-conflux-sdk

Connect Provider

const conflux = new Conflux({
  url: 'https://main.confluxrpc.com',
  networkId: 1029,
})

// Use OneKey provider for signing
conflux.provider = provider

Send Transaction with SDK

// Create and send transaction
const tx = await 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)

Contract Interaction

const contract = conflux.Contract({
  abi: contractABI,
  address: contractAddress,
})

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

// Write
const tx = await contract.someWriteFunction(param1, param2).sendTransaction({
  from: senderAddress,
})

const receipt = await tx.executed()
