Polymarket WalletConnect setup: Safe vs Proxy, MetaMask, WalletConnect

Polymarket WalletConnect is the connection method you use when you want to trade on Polymarket with a non‑browser extension wallet or a mobile wallet. This guide walks you through the difference between a Gnosis Safe (pre‑deployed) and a Proxy wallet (auto‑deployed), then gives step‑by‑step instructions for connecting with MetaMask and WalletConnect, plus common troubleshooting notes.

Key takeaways

• Polymarket supports two wallet types: a pre‑deployed Gnosis Safe and a Proxy wallet that the Relayer deploys on first use. Choose Safe if you already have one; otherwise Proxy is automatic.
• MetaMask can be used as a browser extension or mobile app (via WalletConnect). WalletConnect is how many mobile wallets connect to Polymarket.
• Polymarket trading is gasless: the Polymarket Relayer sponsors gas and handles approvals, but you still need pUSD (Polymarket's wrapped USDC) to trade.
• If a connection fails, check chain (Polygon), wallet firmware/extension updates, and geo restrictions — do not use VPNs to bypass geo blocks.

Why the wallet type matters

Polymarket supports two wallet models on Polygon:

• Gnosis Safe (pre‑deployed): a multi‑sig or single‑owner Safe that you already control off‑chain. If you connect a Safe that Polymarket recognises, the site uses that deployed address for orders and CTF operations.
• Proxy wallet (auto‑deployed): for most users this is easier — Polymarket's Relayer deploys a Proxy wallet for you on first transaction. It behaves like a normal EOAwallet from the UI.

Which to pick

• Use Gnosis Safe if you already manage funds in a Safe and want the same address and policies on Polymarket.
• Use Proxy if you want simple, one‑click onboarding. The Relayer handles deployment and future interactions.

Before you start

• You must use Polygon (chain ID 137) in your wallet. Polymarket trades on Polygon and settlement uses pUSD.
• Have pUSD available to trade; see /guides/how-to-fund-polymarket-with-usdc for funding steps.
• Polymarket sponsors gas through the Relayer; you do not need MATIC for transaction fees.
• Be aware of geographic restrictions listed on Polymarket; do not attempt to bypass blocks with VPNs.

Connecting with MetaMask (browser extension)

1. Install and set up MetaMask

• Install the MetaMask extension for your browser and complete initial setup. Create or import a seed phrase and secure it offline.
• Make sure MetaMask is configured to Polygon (network selection). If Polygon is not present, add it manually using standard Polygon RPC settings.

2. Open Polymarket and select Connect Wallet

• Visit Polymarket and click "Connect wallet". Choose MetaMask from the list of connectors.

3. Approve the connection

• MetaMask will prompt you to connect the selected account. Approve the connection.
• If you have a pre‑deployed Gnosis Safe address you prefer, connect that account that controls the Safe. Polymarket will detect Safe ownership when relevant.

4. First transaction: Proxy deployment (if applicable)

• If you do not already have a Safe and this is your first interaction, the Polymarket Relayer will deploy a Proxy wallet for you when necessary. No gas is required from you; the Relayer handles the deployment.
• You may see MetaMask prompts for signing messages (not gas payments). Approve the signatures to allow the Relayer to use your Proxy.

Connecting with WalletConnect (mobile wallets)

WalletConnect lets mobile wallets talk to Polymarket using a QR code or deep link. Common supported wallets include MetaMask Mobile, Phantom, Rabby, Bitget, OKX, Coinbase, and any EIP‑6963 compatible wallet.

1. Open your mobile wallet app

• Ensure your wallet supports WalletConnect and is configured for Polygon. Update the app to the latest version.

2. From Polymarket, choose WalletConnect

• On Polymarket click "Connect wallet" and choose WalletConnect. A QR code or deep link will appear.

3. Scan or open the deep link

• If you are on desktop, scan the QR code from your mobile wallet's WalletConnect scanner. If you are on mobile, choose the deep link that opens your wallet.

4. Approve the session and account

• Your wallet will prompt you to approve the connection. Select the account you want to use and confirm.
• If you do not have a pre‑deployed Safe, the Relayer will create a Proxy wallet on first use. Expect signing prompts for authorisation; you will not be asked to pay gas.

Safe (Gnosis Safe) specifics

• If you already manage a Safe, connect the account that controls it. Polymarket recognises pre‑deployed Gnosis Safes.
• Using a Safe preserves your on‑chain governance and multisig policies. The user experience differs mainly around transaction signing thresholds and who must sign.

Common first‑time prompts you will see

• Signature requests (authorisations) to allow the Relayer to operate your Proxy or approve off‑chain order settlement. These are not gas payments.
• Approvals for ERC‑20 spending are generally handled by the Relayer when needed. You will be asked to sign approvals; no MATIC is required.

Troubleshooting

Connection fails or wallet not found

• Confirm your wallet is set to Polygon (chain ID 137).
• Update your wallet app or browser extension. Restart the browser or device if needed.
• If WalletConnect times out, reconnect by closing the session in your wallet and creating a fresh WalletConnect session on Polymarket.

Signatures or deployment keep failing

• Ensure you approve the exact account that will be used. Multi‑account mobile wallets sometimes select a different account by default.
• If using a hardware wallet through MetaMask, check that the hardware device firmware is up to date and follow any device prompts.

Geo or regulatory blocking

• Polymarket enforces geo restrictions by IP. If you are in a blocked jurisdiction, the site will prevent new orders. Do not use VPNs; that violates Polymarket's Terms of Service.

Security and best practices

• Keep your seed phrases and private keys offline and never paste them into websites or chat.
• If you use a shared or public device, disconnect your wallet and clear sessions after use.
• Prefer hardware wallets for larger balances; they can be used through MetaMask.

How this affects your trading

Your choice of Safe or Proxy only affects onboarding and signing workflows. Once connected, trading behaviour on Polymarket is the same: the CLOB handles order matching, settlement uses pUSD on Polygon, and the Relayer sponsors gas. You still need pUSD to place orders and you will see signature prompts for Proxy deployment or Safe signoffs on first use. If you plan programmatic access, see Polymarket's API documentation and the relayer SDK for builders.

Closing checklist

• Confirm your wallet is set to Polygon (chain ID 137).
• Choose Safe if you need multisig policies; otherwise accept Proxy for automatic deployment.
• Use WalletConnect for mobile wallets and MetaMask for browser extension flows.
• Keep pUSD funded to trade, and follow Polymarket's geo restrictions.

Frequently asked questions

What is the difference between a Gnosis Safe and a Proxy wallet on Polymarket?

A Gnosis Safe is a pre‑deployed smart contract wallet you already control and can use on Polymarket. A Proxy wallet is automatically deployed by the Polymarket Relayer when you first interact if you don't have a Safe. The Safe preserves multisig and policy controls; a Proxy is simpler for single‑user onboarding.

Do I need MATIC to trade on Polymarket?

No. Polymarket sponsors gas via the Relayer, so you do not need MATIC for transaction fees. You do need pUSD (Polymarket's wrapped USDC) to buy outcome shares.

Can I use MetaMask Mobile to connect?

Yes. MetaMask Mobile supports WalletConnect and can connect to Polymarket using the WalletConnect flow. You can also use MetaMask as a browser extension directly on desktop.

What should I do if WalletConnect times out?

Close the existing WalletConnect session in your mobile wallet, create a new WalletConnect session on Polymarket, and scan the QR code or open the deep link. Ensure your wallet app is up to date.

Is it okay to use a VPN to bypass geo‑blocks?

No. Polymarket's Terms of Service prohibit bypassing geographic restrictions. Do not use VPNs to circumvent blocklists.
