About

Sour Finance

Sour is a non-custodial Solana perpetuals DEX. Every order in a 1.8-second batch settles at one uniform clearing price, removing the front-run/back-run lanes continuous orderbook perp DEXes leave open. Funding is computed inside every batch (no off-chain cron). Flat 3 bps fee per fill, 100% routed to the LP vault. Settlement and aggregate-budget math are formally verified: 18 Kani proofs + Lean spec + 15 property tests at github.com/GageBachik/sour-verification.
