JustBet is a decentralized online casino built using the WINR Protocol on the Arbitrum blockchain. It uses smart contracts to implement games and Supra Oracles to generate randomness, ensuring that payouts are tamper-proof and the casino experience is fast-paced and realistic. Furthermore, every bet placed on JustBet comes with a cashback reward in the form of vWINR tokens, which can be exchanged for WINR tokens after a lock period. Additionally, the platform features a smart index pool as its bankroll, similar to DeFi AMMs, where users can provide liquidity in exchange for a yield generated by gamblers' losses. In conclusion, JustBet offers a unique gambling experience that allows users to gamble as a true on-chain degen, earn rebate rewards, provide liquidity and become the ultimate WINR.
