sidebet is a social layer on top of Polymarket. You pick a side, send a link, and one friend takes the other side. When the market resolves, so does the score.
Connect any wallet — browser extension, or a mobile/hardware wallet over WalletConnect — and sign a free message. No email, no password, no gas. Your address is your account.
Every market, price and trade on sidebet is real Polymarket data. Choose YES or NO and set what it's worth to you.
They open a head-to-head card showing your side, theirs, and the stake — and take the other side in one tap. Accepting is always free, no account required up front.
When the underlying Polymarket market resolves, the challenge resolves with it and your head-to-head record updates. Nobody has to agree on who won.
sidebet never holds your funds and never places bets for you. It is non-custodial: you keep your own keys, and every transaction is signed by you in your own wallet. A challenge is a shared record of who took which side — each person places their own bet on Polymarket and is paid by Polymarket. There is no pot held here, and no escrow.
