Projects
Biscotti Finance
StartupA decentralized exchange on Arc, Circle's stablecoin-native L1, where gas is USDC and there is no volatile native token. Concentrated liquidity, StableSwap, farms, a fair-launch launchpad and on-chain trading battles — V3 math, smart-order router, contracts and indexers all built as one system.
Solidity · Foundry · React Router 7
