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, processed millions of dollars 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 position via WebSocket within 10 to 50 ms. Your copy order is signed and submitted within 500 ms of the original trade. You get the same entry price as the trader you copy.
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.

Non-custodial architecture

Your funds never leave your wallet. Polyfollow uses account abstraction (ZeroDev on Polygon) to create a smart wallet tied to your login. Your private key is encrypted with AES-256 and stored encrypted in our database. We hold the ciphertext only. We cannot move your funds unilaterally, we cannot drain your wallet, and we are never a counterparty to your trades.

Every order is signed by your key on our infrastructure and submitted directly to Polymarket's order book. Your USDC sits in your smart wallet on-chain. Deposits and withdrawals go directly between your wallet and Polymarket with no intermediary step through Polyfollow.

Security posture

• AES-256 key encryption. Private keys are encrypted at rest and in transit. The encryption key itself 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.
• No withdrawal capability. Our server can place and mirror Polymarket orders on your behalf. It cannot initiate withdrawals to external addresses.
• Minimal permissions. We request only the permissions required to trade on Polymarket. You can revoke access at any time from your settings.

For the full security breakdown, including our responsible disclosure policy, see our Security page.

Transparent pricing

Polyfollow charges a single fee: 0.5% on each taker order executed on your behalf. There is no monthly subscription, no performance fee, no fee on winning trades vs. losing trades, and gas is included. Deposits and withdrawals are always free.

If the trader you are copying makes 10 trades and 6 win, you pay the 0.5% fee on all 10 trades. Your profits on the 6 winners are entirely yours. See the Pricing page for the full breakdown.
