OKC v0.19.1版本不再支持homestead签名

Jay

背景：

OKC测试网在高度5300000高度后不再支持homestead签名，仅支持EIP155签名
OKC主网在高度5150000高度后不再支持homestead签名，仅支持EIP155签名
EIP155签名消息中包含chainId, 参考链接

问题：

发送homestead签名交易会报如下错误：

SetFail: dot unauthorized: signature verification failed: deprecated support for homestead Signer

解决方案：

1. we3js开发者(以主网为例)

指定chainId对交易进行签名，会输出rawTransaction

const web3 = require('web3');
const Web3 = new web3(new web3.providers.HttpProvider('https://exchainrpc.okex.org'));
Web3.eth.accounts.signTransaction({
    to: '0xF0109fC8DF283027b6285cc889F5aA624EaC1F55',
    value: '1000000000',
    gas: 2000000,
    gasPrice: '234567897654321',
    nonce: 100,
    chainId: 66
}, 'your-private-key')
    .then(console.log);

将上面签名后的rawTransaction广播到主网中

web3.eth.sendSignedTransaction('rawTransaction').on('receipt', console.log);

2. truffle开发者

使用v5.1.42或以上版本的truffle；依赖的hdwallet-provider package建议使用
"@truffle/hdwallet-provider": "^1.2.3"
需要将truffle-config.js中的require('truffle-hdwallet-provider')改为require('@truffle/hdwallet-provider')，代码中其他地方的引用也需要修改

java 例子：
String erc20Adress="contract address"
Web3j web3j = Web3j.build(new HttpService(your url));
Credentials credentials = Credentials.create(your privateKey);
txManager = new RawTransactionManager(web3j, credentials, Byte.valueOf(web3j.netVersion().send().getNetVersion()));//注意传入 chain-id；
Function = new Function();
String txData = FunctionEncoder.encode(function);
String txHash = txManager.sendTransaction(
DefaultGasProvider.GAS_PRICE,
DefaultGasProvider.GAS_LIMIT,
erc20Adress,
txData,
BigInteger.ZERO
).getTransactionHash();
receiptProcessor = new PollingTransactionReceiptProcessor(
web3j,
TransactionManager.DEFAULT_POLLING_FREQUENCY,
TransactionManager.DEFAULT_POLLING_ATTEMPTS_PER_TX_HASH);
boolean result= receiptProcessor.waitForTransactionReceipt(txHash).isStatusOK();
System.out.println(result);

python 例子：
rawTx = {
'from': fromAddr,
'nonce': nonce,
'gasPrice': gasPrice,
'chainId':65, //这里加入chainId
'gas': 300000,
'value': web3.toWei(0,'ether'),
'data': ''
}

def deploy(rawTx):
signedTx = web3.eth.account.signTransaction(rawTx,privateKey)
hashTx = web3.eth.sendRawTransaction(signedTx.rawTransaction).hex()
receipt = web3.eth.waitForTransactionReceipt(hashTx)

使用hardhat 框架部署的呢？应该如何配置？请指导一下？
