This is the personal package to be used to sign txs.

INSTALL

npm install youchainjs-tx

USAGE

• example

####1、默认配置

const YOUTransaction = require('youchainjs-tx').YOUTransaction;
const privateKey = Buffer.from(
  'e331b6d69882b4cb4ea581d88e0b604039a3de5967688d3dcffdd2270c0fd109',
  'hex',
);

const txParams = {
  nonce: '0x00',
  gasPrice: '0x09184e72a000',
  gasLimit: '0x2710',
  to: '0x0000000000000000000000000000000000000000',
  value: '0x00',
  data: '0x7f7465737432000000000000000000000000000000000000000000000000000000600057',
};

// The second parameter is not necessary if these values are used
// const tx = new YOUTransaction(txParams, { chain: "youchain"  });
// const tx = new YOUTransaction(txParams, { chain: 2  });
const tx = new YOUTransaction(txParams);
tx.sign(privateKey);
const serializedTx = tx.serialize();

####2、设置 networkId

const YOUTransaction = require('youchainjs-tx').YOUTransaction;
const privateKey = Buffer.from(
  'e331b6d69882b4cb4ea581d88e0b604039a3de5967688d3dcffdd2270c0fd109',
  'hex',
);
const Common = require('youchainjs-tx').Common;
const customCommon = Common.forCustomChain(
  'youchain',
  {
    name: 'my-network',
    networkId: 2,
  }
);

const txParams = {
  nonce: '0x00',
  gasPrice: '0x09184e72a000',
  gasLimit: '0x2710',
  to: '0x0000000000000000000000000000000000000000',
  value: '0x00',
  data: '0x7f7465737432000000000000000000000000000000000000000000000000000000600057',
};

const tx = new YOUTransaction(txParams,   { common: customCommon });
tx.sign(privateKey);
const serializedTx = tx.serialize();

Chain and Hardfork Support

The Transaction and FakeTransaction constructors receives a second parameter that lets you specify the chain and hardfork to be used. By default, mainnet and petersburg will be used.

There are two ways of customizing these. The first one, as shown in the previous section, is by using an object with chain and hardfork names. You can see en example of this in ./examples/ropsten-tx.ts.

The second option is by passing the option common set to an instance of [common]' Common. This is specially useful for custom networks or chains/hardforks not yet supported by ethereumjs-common. You can see en example of this in ./examples/custom-chain-tx.ts.
