go-steem/rpc is the Steem RPC client library for Golang. I am happy to announce that I have just released version 0.4.0, which adds support for transaction signing and broadcasting.

Release Notes

There are many changes to the package, including some breaking changes. The most visible change is obviously that it is possible to sign and broadcast transactions using network_broadcast_api. You can read the full release notes on GitHub:

This is a very exciting release since from now on go-steem/rpc supports signed transactions! This means that it is not only possible to read data from the blockchain, you can broadcast new transactions as well!

What Is Next?

For the next release I would like to focus on cleaning up the new APIs. There is also going to be a hardfork, which can bring some breaking changes. I will try to keep go-steem/rpc up to date with the changes to come.
