Storm3

• 使用

  • 安装
    • npm install storm3-usv-js -D

• 创建storm3实例

 let Storm3 = require('storm3-usv-js');
 let storm3:Object = new Storm3('http://');

• 创建地址

let account:Object = storm3.accountCreate('随机字符串');
// 地址
account.address;
// 私钥
account.privateKey

• 查询地址余额

let balance:Number = await storm3.getBalance('地址');

• 查询块高

let blockNumber:Number = await storm3.getBlockNumber();

• 校验地址

let isValidAddress:Boolean = storm3.isValidAddress('地址');

• 查询块交易

let blockTransactions:Array = await storm3.getTransactionsByBlock(29)

• 查询交易详情

let transaction:Object = await storm3.getTransaction('交易哈希')

• 查询交易凭证

let transactionReceipt:Object = await storm3.getTransactionReceipt('交易哈希')

• 签名交易

 let privateKey = '私钥（带0x）';
 let to = '地址'
  // 通过私钥获取账号
  let account = storm3.privateKeyToAccount(privateKey);
  // 获取nonce
  let nonce = await storm3.getTransactionCount(account.address);
  // 转换私钥
  privateKey = Buffer.from(privateKey.substring(2), 'hex');

  let rawTx = {
    nonce: nonce,
    gasPrice: storm3.utils.toHex(0),
    gasLimit: storm3.utils.toHex(4300000),
    gas: storm3.utils.toHex(41000),
    to: to,
    value: 0,
    data: storm3.utils.toHex('')
  };
  // 使用 Storm3.SignTx 进行转换
  let tx = new Storm3.SignTx(rawTx);
  // 签名
  tx.sign(privateKey);
  let serializedTx = tx.serialize();
  // 发送交易
  let hash = await storm3.fst.sendSignedTransaction('0x' + serializedTx.toString('hex'));
  console.log(hash);
