Web3 fantasy sports that feel like Web2 - stablecoin contests paid out onchain. Live on Arbitrum sepolia - contests running everyday. Fast & Friendly UX, and transparent payouts.
aiSports is a Daily Fantasy Sports app that’s been validated with real users over multiple seasons and is now being retrofitted for EVM + stablecoin contests on Arbitrum.
The goal is simple: bring, stablecoin based real-money DFS to the masses with an experience that feels like web2 - fast onboarding, familiar contest UX, and transparent settlement. Contest funds are escrowed onchain and distributed from a verifiable contract.
Stablecoins are the unlock - we have USD-denominated entry fees and payouts. On Arbitrum testnet, contests run using PYUSD. Our contracts are built with yearn vaults, so we can easily turn our prize pool into a yield bearing asset. This helps to generate revenue for the protocol, and unlock bigger contest prizes.
Get testnet PYUSD: Head to paxos faucet to grab some PYUSD (https://faucet.paxos.com/). Make sure you have some testnet eth for gas: https://www.hackquest.io/faucets/421614

<p><span>During the buildathon, I implemented and finalized a DFS-focused EVM escrow contract (DFSEscrowManager.sol) designed for stablecoin contests: multi-entry functionality and onchain payout distribution. I then deployed and verified the contract on <strong>Arbitrum Sepolia</strong>, configured for <strong>official testnet PYUSD</strong> to support realistic USD contest flows.</span></p><p><span>I updated the apps front end to work with EVM based stablecoin contracts. This enabled a clean Arbitrum testnet contest where with easy stablecoin PYUSD entry.</span></p>
