Use chainId when signing a transaction

[adridadou]

Have a look at the issue I've created on web3js
web3/web3.js#526

Basically the issue is that the way tx are signed has changed

Thanks for the heads up. Will update the transaction object to support this.

Is it causing you any issues currently? From what Vitalik has said & the previous transaction signing mechanism should still be fine in the meantime - I didn't have any issues using it myself during last week post HF.

This has been implemented. However, it's not enabled in the web3j smart contract wrappers. I'd rather wait until we have a JSON-RPC call or similar for obtaining the chainId, so users don't have to provide the chainId web3j.

The RawTransactionManagers used by smart contract wrappers as of upcoming version 1.2 allows you to specify the chain id on all transactions.
