Wallet Options for Polymarket
Polymarket supports multiple wallet connections: MetaMask, Rabby, Coinbase Wallet, WalletConnect, and any EVM-compatible wallet. You can also use Polymarket without a wallet — it creates a built-in smart wallet for you.
Connecting an external wallet gives you full control over your private keys and lets you interact with other DeFi protocols. The built-in wallet is simpler for beginners.
Connecting MetaMask
Install MetaMask browser extension from metamask.io. Create or import a wallet. Make sure you are on the Polygon network (MetaMask may auto-switch when you connect to Polymarket).
Click Connect Wallet on Polymarket and select MetaMask. Approve the connection in the MetaMask popup. Your wallet address now appears on Polymarket and you can deposit USDC to start trading.
Other Wallet Options
Rabby wallet offers a smoother experience with automatic chain switching and transaction simulation. Coinbase Wallet works great for users already on Coinbase. WalletConnect supports mobile wallets like Trust Wallet and Rainbow.
For the best trading experience, we recommend Rabby for desktop users and Coinbase Wallet for mobile. Both handle Polygon transactions smoothly.
Troubleshooting Connection Issues
If your wallet does not connect, try: clearing your browser cache, disabling other wallet extensions, switching to the Polygon network manually, or using a different browser. Chrome and Brave work best.
Ensure your wallet has a small amount of MATIC for gas fees (usually $0.01 worth is enough). Without MATIC, you cannot sign transactions on Polygon.

Frequently Asked Questions
Do I need an external wallet?
No. Polymarket creates a built-in smart wallet for email signups. External wallets are optional but give you more control.
Which wallet is best for Polymarket?
For beginners, use the built-in wallet. For active traders, Rabby offers the best UX with automatic chain switching and transaction previews.
Can I use a hardware wallet?
Yes. Connect Ledger or Trezor through MetaMask or Rabby for maximum security. Hardware wallets add a physical signing step to every transaction.
Why does it say wrong network?
Make sure your wallet is connected to the Polygon network. MetaMask users can add Polygon via chainlist.org or let Polymarket auto-switch.
