Arcadeum is a decentralized casino that's fully on-chain and self-custodial, with a provably low and highly competitive house edge. Arcadeum supports USDT-denominated bets and pays out rewards in USDT. Players must first approve their USDT spend limit on a smart contract before they can start playing games. To ensure everything runs smoothly, there are max bet limitations based on the max payout of each bet, the bet size, and the amount of USDT in ALP, which functions as the "house". Bets are a two-transaction synchronous and non-reentrant process.
