How Bet Credits Work
Bet credits allow you to place bets without using your own funds. If you win, you keep the winnings, but not the original bet amount.
Bet Credits & Cross-chain Betting
If you're betting on Arbitrum, Scroll or Mode, you can access your bet credits by switching to SX Rollup. Learn more about what's available on the Arbitrum network below. To unlock the full functionality of SX Bet, select SX Rollup.
