TOOL #04 · OFFICIAL POLY-MARKET-MAKER BANDS SIMULATOR GitHub: Polymarket/poly-market-maker ↗

Official `Polymarket/poly-market-maker` Bands Strategy & Daily Liquidity Rewards Simulator

Visualize Bid/Ask order bands around mid-price, estimate daily USDC Liquidity Rewards + spread capture APY, and auto-generate production `bands.json` configs for `Polymarket/poly-market-maker`.

01 · Tool Overview & Quantitative Mechanism

Passive limit orders (Maker) on Polymarket pay **0% trading fees** and earn daily **USDC Liquidity Rewards** whenever your resting Bids and Asks sit within the maximum spread band (typically ±2¢ of mid-price)—even if your orders never get filled!

Polymarket's official `poly-market-maker` repository automates this with the `Bands` keeper strategy: maintaining symmetric Bid/Ask bands around live mid-price, auto-canceling/replacing orders when price shifts, and compounding round-trip spread capture + daily USDC rewards.
