WazirX Go Connector

WazirX is one of India’s largest crypto exchanges, and while its REST API is well documented, it doesn’t ship an official Go client. I wanted to poke at their API for a side project and didn’t want to hand-roll request signing and endpoint plumbing every time, so I built wazirx-connector-go and open-sourced it once it was in decent shape.

The exchange exposes close to two dozen endpoints — tickers, order book depth, order placement, withdrawals, sub-account transfers, and so on. Writing a hand-rolled method for each one would have meant the same boilerplate repeated two dozen times: build params, sign if needed, pick GET/POST/DELETE, hit the URL, parse the response.

After building the Go connector for WazirX, I wanted the same thing on the JVM — but WazirX doesn’t publish an official Java client at all, REST or WebSocket. The REST half was a fairly direct port of what I’d already learned building the Go client. The WebSocket half turned out to be its own project.

Letting callers choose their failure granularity

For errors, I didn’t want every caller forced into one giant catch-all exception, but I also didn’t want to force a try/catch at every single call site. I split errors into two, with one extending the other:
