On August 25, SX Bet will move to V3 — the biggest upgrade in the exchange's history. We have spent the last 12 months streamlining the site to become the most efficient, scalable and secure onchain prediction market in the world.

Built for speed

The matching engine has been rebuilt from scratch. Placing an order is ~80% faster than V2, and bet-to-onchain confirmation is 2–3× faster. Two V2 headaches are simply gone: failed fills, and the race between a cancel and a fill. When your bet matches, it settles.

Native Orderbashing

Orders that cross the book fill instantly against resting liquidity instead of resting. No more negative vig opportunities for bots to pick up, users will get the best price no matter what.

Privacy

Positions are fully private with V3. No more copy trading or rotating accounts. The public order book shows aggregated price levels — not individual orders. Your offers, trades, and positions are no longer attributable to your address. Size up without showing your hand.

Mutli-sig Security Optionality

For the security conscious, users can now lock withdrawals and transfers behind a multi-sig wallet. The first onchain prediction market to offer this.

Industry-Low Fee

Current prediction markets charge on the stake of a bet, meaning win or lose you pay a fee on the stake of your bet. SX Bet will be charging a 1% fee on just the profit you make with taker bets, makers pay 0%.

Here is how a $100 bet at even odds stacks up with Polymarket and Kalshi.

Simplified API endpoints

One signed order does everything and our docs are optimized for AI onboarding. Get your automated trading strategy live in a matter of minutes instead of days.

What to do before August 25

Regular users: Nothing. Login on the 25th and enjoy the new site.

API traders and market makers: Migrate your code to V3. This should take 30-60 minutes of your time and our team is available to help.

Follow the migration guide to get started. You can also test your migration on our testnet, now live at toronto.sx.bet.

New builders can go from zero to a placed bet with the Quickstart.

At cutover on August 25 at 10:00 AM ET, all open V2 orders will be automatically cancelled and V2 clients will stop working.
