Before you connect
Have the wallet you intend to use available in its normal browser extension or mobile app. Use the official Polymarket domain, not a link sent in a direct message, an ad, or a lookalike page. You should know which wallet account is selected before the first prompt appears.
Connect your wallet: 1–2–3
Open Sign Up and choose a wallet
Open the official Polymarket site, select Sign Up, then choose the crypto-wallet option and the wallet provider you actually control. Polymarket currently names MetaMask, Rabby and Phantom as examples.
Approve the connection message
Your wallet should ask you to sign the message that connects it to Polymarket. Read the requesting site and message in the wallet before approving; a signature proves control of the wallet, but it is not a reason to approve an unfamiliar request.
Review the trading-enable message
Polymarket’s current signup guide documents a second message to enable trading. Confirm only when the request is in the official Polymarket flow and the wallet shows the account you intended to use.
Choose wallet→Review connection message→Review trading-enable message
Polymarket’s public signup instructions list those two message requests, but wallet interfaces can differ. If the provider name, account, site domain or request type looks materially different from what you expected, reject it and start again from the official site.
What the two signatures mean
A signature is a wallet’s confirmation that you control the selected account and agree to the message shown. In the current Polymarket wallet signup flow, the first message connects that wallet and the second enables trading. They are distinct prompts, so inspect both.
| Prompt type | What to confirm | Safe response if it differs |
|---|---|---|
| Connection or sign-message request | The official Polymarket site, the selected wallet account and readable purpose. | Reject it if the domain or request is unfamiliar. |
| Trading-enable message | That it appears immediately in the official wallet signup flow and is the second documented request. | Pause and reopen the official flow if it is unexpected. |
| Transaction, allowance or transfer request | The asset, amount, recipient and purpose—none should be assumed from a connection guide. | Do not approve it unless you intentionally started that separate action and understand it. |
The useful distinction is not “signatures are always safe.” It is that a request should match the action you deliberately started. A request to move assets or grant an allowance belongs to a separate funding or trading decision.
What to check before approving
- Domain: begin at the official Polymarket site rather than following an unsolicited link.
- Wallet account: make sure the address selected in the wallet is the account you meant to use.
- Request type: a connection message is different from a transaction, asset transfer or token approval.
- Purpose: stop if the request is unreadable, unrelated to connecting, or appears after you left the Polymarket flow.
What happens after connection
After both documented messages are accepted, Polymarket says you can log in using the connected wallet. That does not require you to deposit or trade. If you later decide to fund an eligible account, use the current Polymarket deposit guide and follow the details shown in your own Deposit panel.
Connecting a wallet also does not answer an identity-check or location question. For that distinction, see Does Polymarket Require KYC? and the Countries and Availability hub.
If connection does not work
Do not solve a failed connection by installing an unknown extension, importing a recovery phrase into a website, or changing your location. Instead, verify the official domain, confirm the intended wallet account is selected, and retry from the official signup flow only when the prompt is clear.
If the issue is account-specific, use official Polymarket support. Do not post a wallet address, screenshots with balances, login codes or wallet recovery information in a public request for help.
Bottom line
Connect a wallet by choosing the crypto-wallet path in Polymarket’s Sign Up flow and reviewing both documented messages one at a time. The safest completion check is that the official flow recognizes the wallet you meant to use—not that you have approved every prompt or moved funds. Eligibility, deposits and trading remain separate decisions.
Frequently Asked Questions
How do I connect a wallet to Polymarket?
To connect a wallet to Polymarket, open the official site, select Sign Up, choose the crypto-wallet option and select your provider. Polymarket’s current guide then asks for one message to connect the wallet and another to enable trading. Review both requests in the wallet before signing.
Which wallets can I connect to Polymarket?
Polymarket currently gives MetaMask, Rabby and Phantom as examples in its signup guide. The provider choices shown in the live flow can change, so choose only a wallet you control and use the option currently displayed by Polymarket.
Why does Polymarket ask for two wallet signatures?
Polymarket documents two separate messages in its crypto-wallet signup path: one to connect the wallet and another to enable trading. The practical point is to read each request separately rather than treating a second prompt as automatic or interchangeable with the first.
Does connecting a wallet to Polymarket move my crypto?
No, a connection or message-signature prompt is not the same thing as sending crypto. Do not rely on that distinction blindly: read the wallet’s request and stop if it instead asks you to approve a transaction, token allowance or transfer you did not intend.
Is connecting a wallet to Polymarket the same as KYC?
No. Connecting a wallet proves control of that wallet through the documented messages; it is not the same as a routine identity-document upload. Geographic availability and any third-party funding-provider checks are separate questions.
Can I connect a wallet to Polymarket from a restricted location?
Do not treat a successful connection screen as permission to trade. Polymarket says location restrictions can limit platform actions and prohibits VPNs or similar tools used to bypass those restrictions. Check your physical-location status before funding or trading.
What should I do if my Polymarket wallet connection fails?
First close the request, confirm you are using the same wallet and browser profile that you intended, then return to the official Polymarket flow and try again only if the request looks correct. Do not reveal a seed phrase, recovery phrase or private key to solve a connection error; use official Polymarket support for account-specific help.
Open Polymarket and choose the wallet option
Start from the official Sign Up flow, then review the selected wallet account and each message before signing.
Connection does not establish geographic eligibility or permission to trade.
