Market maker bot

Instead of traditionally LP'ing funds into a liquidity pool, on ZigZag's order book users can run a market maker bot. This means users are stepping into DeFi and getting yield on their funds without impermanent loss. Market making supports ZigZag with more liquidity, while the user gets a profit from the spread. Make sure to rebalance when needed!

Anyone can run a market maker bot on zkSync Lite. The market maker bot fills market and limit orders. Technical instructions on how to run the bot can be found in the README in the market-maker repository on GitHub. The code can be found on this specific GitHub page.

If you need a more simplified step-to-step explanation on how to start running your own market maker bot, please continue reading.
