交易

签名前先连接 provider，并确认所选网络。直接注入的 provider 与 Aptos Wallet Standard 适配器使用不同的参数类型，请勿混用示例。请替换省略的地址，并为只读请求初始化 SDK 客户端。

了解如何在 Aptos 上签署和提交交易。

签署并提交交易


// Simple APT transfer
const payload = {
  type: 'entry_function_payload',
  function: '0x1::aptos_account::transfer',
  type_arguments: [],
  arguments: [
    '0x1234...', // Recipient address
    '100000000', // Amount in Octas (1 APT = 100000000 Octas)
  ],
}
 
const response = await provider.signAndSubmitTransaction(payload)
 
console.log('Transaction hash:', response.hash)

签署交易（不提交）


const payload = {
  type: 'entry_function_payload',
  function: '0x1::coin::transfer',
  type_arguments: ['0x1::aptos_coin::AptosCoin'],
  arguments: ['0x1234...', '100000000'],
}
 
const signedTxn = await provider.signTransaction(payload)
 
// Submit later using Aptos SDK
// const pendingTxn = await client.submitTransaction(signedTxn)

签署交易 V2（BCS 序列化）

用于 BCS 序列化交易的高级用例：


const rawTransaction = '<BCS_SERIALIZED_TRANSACTION>'; // Use the encoding expected by your wallet version
 
const signedTxn = await provider.signTransactionV2({
  transaction: rawTransaction,
  transactionType: 'simple', // 'simple' or 'multi_agent'
  asFeePayer: false,
})

交易选项


const payload = {
  type: 'entry_function_payload',
  function: '0x1::aptos_account::transfer',
  type_arguments: [],
  arguments: ['0x1234...', '100000000'],
}
 
// The legacy direct method takes only a payload.
const response = await provider.signAndSubmitTransaction(payload)
// For gas options, use signAndSubmitTransactionV2 with the matching Wallet Standard input.

智能合约交互

调用视图函数


// View functions don't require signing
const result = await client.view({
  function: '0x1::coin::balance',
  type_arguments: ['0x1::aptos_coin::AptosCoin'],
  arguments: [accountAddress],
})
 
console.log('Balance:', result[0])

调用入口函数


// Mint NFT example
const payload = {
  type: 'entry_function_payload',
  function: '0x3::token::create_collection_script',
  type_arguments: [],
  arguments: [
    'My Collection',           // Collection name
    'Description',             // Description
    'https://example.com',     // URI
    '1000',                    // Maximum supply
    [false, false, false],     // Mutability config
  ],
}
 
const response = await provider.signAndSubmitTransaction(payload)

多代理交易

用于需要多个签名者的交易：


const signedTxn = await provider.signTransactionV2({
  transaction: rawTransaction,
  transactionType: 'multi_agent',
})

代付手续费交易

作为代付方签署赞助交易：


const signedTxn = await provider.signTransactionV2({
  transaction: rawTransaction,
  transactionType: 'simple',
  asFeePayer: true,
})
