Needs a Polymarket wallet with a private key and careful review of which wallets to follow.

In plain English

This is a copy trading bot for Polymarket, a prediction market platform where people bet on the outcome of real world events covering politics, sports, cryptocurrency prices, economics, and more. Copy trading means the bot automatically mirrors the trades of chosen, more experienced traders, called leaders, placing similar bets whenever those wallets make a move. The idea behind the project is to avoid the difficulty of predicting fast moving markets directly, and instead follow traders who already have a track record. Development began in early 2026, with the author testing strategies on historical data and a small live balance before settling on this approach. Rather than guessing whether Bitcoin will rise or a candidate will win an election, the bot watches a list of target wallet addresses and copies their positions on the user's behalf. The author designed the strategy around steady, disciplined growth rather than chasing large risky wins, and built it to spread activity across different kinds of markets: slower, news driven political and economic markets alongside faster moving sports and crypto markets that need quicker execution. Settings live in a TOML configuration file, while wallet credentials such as the private key and wallet address go into a separate environment file. Getting started means cloning the repository, installing dependencies, and supplying Polymarket wallet credentials before running the bot, which then operates in the background, watching leader wallets and reacting to their new trades. The author also mentions a separate, more advanced private version built in Rust for lower latency execution, available on request, alongside a public list of the wallet addresses it currently follows.
