Smart Contract Bets and Privacy: What an On-Chain Wager Reveals

Smart contract betting moves the wager itself onto a blockchain. Stake, odds, outcome and payout all become entries in a public ledger that anyone can read. That design offers something traditional sportsbooks cannot, since bettors can check settlement without trusting the operator's database. The same openness also turns every bet into a permanent public record tied to a wallet address. Bettors who understand what an on-chain wager exposes, and how it differs from a bet at a custodial crypto book, can weigh verification against visibility. Contract bets record more fields than a simple transfer.
