Sotto

Sealed-bid batch auction DEX where front-running is structurally impossible.

Sotto is a sealed-bid batch auction DEX built on Flare, where front-running is structurally impossible: orders are encrypted to a TEE enclave key and every order in a batch clears at a single uniform price.

Google Confidential Space TDX attestations are verified fully on-chain through an RS256 verifier, with the clearing price bounded to the FTSOv2 feed.

Live on the Coston2 testnet, built for Flare Summer Signal.
