Polyfollow

Polyfollow combines a public trader leaderboard and wallet analytics with rules for mirroring selected Polymarket wallets. Users inspect public activity, choose a trader, and configure which trades and sizes may be copied to their own account. It is an automated execution workflow rather than a read-only alert: fills can differ or fail, and wallet permissions, custody, fees, sizing rules and metric methodology still require access review. The security page says Polyfollow holds encrypted signing keys and can sign orders and withdrawals on its servers; it explicitly does not describe this as non-custodial. The published execution charge is 1% for taker orders or 0.5% for maker orders, in addition to venue fees. Public research and charged copy execution are separate scopes. The provider retains encrypted signing keys capable of server-side orders and withdrawals.
