About Polyfollow

How Polyfollow started

Polymarket has some of the world's sharpest prediction market traders, but tracking their activity and placing matching trades in real time is technically demanding. Polyfollow was built to close that gap: anyone with USDC on Polygon can now piggyback on expert research without monitoring markets around the clock.

The platform went live in 2025 and has since tracked thousands of Polymarket wallets, placed more than $1 million in copy trade volume, and grown a community of traders who prefer data-driven prediction market investing over guesswork.

How copy trading works on Polyfollow

1. 1
   Browse the leaderboard. Filter traders by all-time profit, win rate, specialty category (sports, crypto, politics), or quality score. Each profile shows verified on-chain P&L.
2. 2
   Set your parameters. Choose how much to allocate per trader, set minimum and maximum odds filters, define a per-position size limit, and optionally configure a stop-loss.
3. 3
   Automatic execution. Our trade watcher detects each new trade through Polymarket's real-time feed and your copy order is signed and submitted right after. The delay and the price difference versus the trader are measured on every copy and published live on our Reliability page. Your fill price can differ from the trader's.
4. 4
   Monitor in real time. Your dashboard shows open positions, realized P&L, trade history, and push notifications. Pause or stop copying any trader with one click.

Your wallet and your key

Each account gets its own Polymarket wallet on Polygon. Your USDC sits in that wallet on-chain, never in a pooled Polyfollow account, and we are never a counterparty to your trades. The wallet is controlled by a signing key we create for you. To copy trades while you are offline, our servers keep that key encrypted (AES-256-GCM) and use it to sign your orders, sales, redemptions and the withdrawals you request.

Because our servers hold the key, Polyfollow's systems can technically sign transactions for your wallet, so we don't describe Polyfollow as non-custodial. You can export the private key from Settings at any time and use the wallet without us, for example in MetaMask or on Polymarket directly.

Security posture

• AES-256 key encryption. Trading keys are encrypted at rest and only decrypted in memory to sign. The encryption secret is stored separately from the ciphertext.
• Row-level security. Every database table is protected by Supabase RLS policies. Your data is visible only to your authenticated session.
• On-chain and verifiable. Your wallet, its trades and every withdrawal are public on Polygon, so you can check any movement of your funds.
• Exportable key. Export your wallet's private key from Settings whenever you want, and move your funds without Polyfollow.
