Polymarket Copy Trading Bot. Mirror successful trades on prediction markets.

In simple English

This tool copies the bets placed by successful traders on Polymarket. It watches their accounts every second and makes the same trades for you. You need your own crypto wallet, some funds, and a database to run it. It comes with a web page so you can see your profits and change settings. You could lose money if the traders you copy make bad bets.

What it is

A TypeScript application that monitors specific crypto wallet addresses on Polymarket and replicates their trades automatically. It includes a web dashboard, configuration options for position sizing, and Docker support for server deployment.

What it is good for

Anyone who wants to follow specific forecasters on Polymarket without watching the prediction market all day long.
