Adding 4swap to CCXT

This is the first time we’re integrating an exchange on the Mixin network into CCXT, but the process is actually more straightforward than expected.

Overview

CCXT started as an SDK to simplify connecting to various centralized exchanges. However, with the recent addition of Hyperliquid—a decentralized exchange on an EVM network—CCXT is expanding its reach, paving the way for more DEX integrations across different networks.

To add a new exchange to CCXT, we create a file under /ts/src/ named [exchange-name].ts. This file defines the methods available when initializing an instance of the exchange. It inherits the base class in /ts/src/base/Exchange.ts, which contains all possible methods for an exchange. We implement only the necessary ones for the new exchange in the new file.

So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!

Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.

* Off the top of my head *

1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it

    git remote add my-fork git@github...my-fork.git
