Perps Market Making Bot

Show quotes on both sides of the orderbook to profit from trading activity
We've open-sourced an example market-maker bot. The bot provides liquidity to Zeta DEX by issuing bid & ask quotes per asset and instrument. It monitors mark prices from an external exchange via web sockets, and monitors quote orders via both web sockets and periodic refreshes.
Makers pay no fees on Zeta DEX (excluding SOL transaction fees), so go crazy!
If things are going well and you want to scale it up, reach out to us about our Market Maker Rewards program.
