Go-Tron

A Tron API implementation written in Go

Notice

This API is currently in alpha and it is not recommended it be used in production. Use this at your own risk. When the API is stablized this notice will be removed and an issue will be filed indicating that it is safe to use. This will be done when test coverage hits a healthy percentage and the API has matured a bit.
