Competition winners included new solutions for Superchain oracle data access, liquidity pool swap rewards, and a lending and borrowing protocol built with v4 hooks.
Last week, we brought together developers from across the Uniswap ecosystem to build on Unichain with our team in New York. The first Unichain Friends & Family Hackathon was a 24-hour sprint for core teams and community builders to explore new ideas: from integrating superchainERC20, to creating interop-enabled solutions for v4. What you can build on Unichain is nearly limitless. The winning teams introduced projects that push what’s possible for DeFi on the Superchain: from data access to user incentives.
First Prize: AnyPrice (Bryan, Solo Labs)
AnyPrice allows dApps on one chain (like OP Mainnet) to fetch real-time prices from oracles on another (like Base) via Optimism's L2-to-L2 messaging. AnyPrice amplifies Uniswap's ecosystem impact by making its oracle data, especially from Uniswap V4, securely accessible across the entire Superchain. This enables developers anywhere to build cross-chain applications leveraging Uniswap's reliable price feeds as the foundational data source, regardless of where the liquidity or V4 deployment resides.

2nd place: Swoupon (Nolan, Derek, Rafael, Joel):
Swoupon is a liquidity pool rewards system that issues Swoupon, an ERC-20 token, for each swap you make that can be later redeemed for free swaps. Users accumulate Swoupon tokens through swaps, encouraging consistent interaction. Fee waivers apply for users with significant token holdings, fostering long-term liquidity provision. And fees are adjusted dynamically based on vault balances and swap conditions, with Chainlink price oracles used to ensure accuracy in evaluating ETH and BTC values.

3rd place: MiladyBank (Mehran):
Milady Bank is a lending and borrowing protocol built with Uniswap v4 hooks. The protocol focuses on offering optimized interest rates. The MiladyBank contract is the central component of the protocol, handling deposit management, borrowing logic, the interest rate model, health monitoring, and liquidation triggers, and offering users isolated risk markets for asset pairs, optimized capital efficiency, and real-time interest rate adjustments. The MiladyBankRouter Contract serves as the user-facing interface to the protocol, providing gas-optimized transaction batching, slippage protection, and simplified position.
Congrats to the winning teams, and to all the builders who participated. We’re excited to support these projects as they develop. Unichain Infinite Hackathon rewards are open to all developers. If you have a project that you’ve been working on, apply here to learn more about grant eligibility, and explore Optimism’s RFPs for Superchain builders.
Special thanks to Uniswap Labs, Optimism and Alchemy.
