Polyfollow gives every account its own trading wallet on Polygon, and lets you export its private key. Here's exactly how it works, including what you trust us with.
Pooled Platforms vs Polyfollow
| Pooled platform | Polyfollow |
|---|---|
| Your funds sit in the platform's wallet | Your funds sit in a separate wallet of your own |
| Your balance is an entry in their books | Your balance is on-chain, visible on Polygonscan |
| No key you can take with you | You can export your wallet's private key anytime |
What we hold: to copy trades while you're offline, our servers keep your wallet's key encrypted and use it to sign your trades, sales, redemptions and the withdrawals you request. That means our systems can technically sign transactions for your wallet, so we don't call Polyfollow non-custodial. Exporting your key gives you a way to use the wallet that doesn't depend on us.
How Your Polyfollow Wallet Works
When you sign up, we automatically create a dedicated Polygon wallet for you:
| Feature | Details |
|---|---|
| Network | Polygon (MATIC) |
| Currency | USDC stablecoin |
| Private Key | Created for you, stored encrypted on our servers |
| Ownership | A separate wallet for your account, never pooled |
| Exportable | Yes - anytime |
This wallet is a real blockchain address. You can view it on Polygonscan, send funds to it from any exchange, or import it into MetaMask.
Exporting Your Private Key
You can export your private key from Settings → Export Private Key.
When to Export
| Reason | Recommended? |
|---|---|
| Backup | Yes - store a copy safely |
| Use in MetaMask | Yes - access from any device |
| Self-withdraw | Yes - if you prefer direct control |
| Platform issues | Yes - always have a backup plan |
How to Export
- Go to Settings in your dashboard
- Scroll to Security section
- Click "Export Private Key"
- Confirm your identity
- Copy your private key immediately
Private Key Security
Your private key is like the master password to your funds. Anyone with this key can access your wallet.
Do's
| Action | Why |
|---|---|
| Store offline | Paper backup in a safe place |
| Use a password manager | Encrypted storage like 1Password |
| Keep it secret | Never share with anyone |
| Have a backup | In case you lose access |
Don'ts
| Never Do This | Risk |
|---|---|
| Screenshot and save to photos | Anyone with phone access can see |
| Send via email/text | Can be intercepted |
| Store in cloud (Google Drive, iCloud) | Can be hacked |
| Share with "support" | Scam - we NEVER ask for keys |
Why Your Exported Key Matters
| Event | With your exported key |
|---|---|
| Polyfollow offline or shut down | Import the key into a wallet and reach your funds on-chain |
| Server problems | Sign in to Polymarket with the key and manage positions directly |
| You want to leave | Withdraw from the app, or move funds yourself with the key |
Your wallet and its funds live on the Polygon blockchain. The key is what lets you reach them, so keep a backup.
Using Your Wallet Outside Polyfollow
With your exported private key, you can:
| Action | How |
|---|---|
| Import to MetaMask | Settings → Import Account → Paste key |
| View on Polygonscan | Enter address on polygonscan.com |
| Trade on Polymarket directly | Access your positions without us |
| Send funds anywhere | Full control over transfers |
Frequently Asked Questions
"Does Polyfollow have access to my funds?"
Our servers hold your wallet's key (encrypted), so technically yes: they can sign transactions for your wallet. We use that to place, sell and redeem your copy trades and to send the withdrawals you request. Your funds are never pooled with anyone else's, every transaction is public on Polygon, and with your exported key you can always reach the wallet without us.
"What happens if Polyfollow shuts down?"
- Export your private key (do this now as a backup!)
- Import into MetaMask or any Polygon wallet
- Access your funds directly on-chain
- Trade on Polymarket using their direct interface
"Is my private key stored securely?"
Yes. Your private key is:
- Encrypted at rest with AES-256-GCM
- Never stored in plain text
- Only decrypted in memory when exporting or signing transactions
- Encrypted with a secret kept separately from the database where the ciphertext lives
Best Practices
- Export and backup your private key immediately after signup
- Store it offline - paper in a safe, or hardware password manager
- Test it works - import into MetaMask once to confirm
- Never share - no legitimate support will ever ask for it
- Keep USDC only - don't send random tokens to this wallet
