Fairblock and Anagram collaborate to introduce FairyCoW Swap, delivering encrypted order protection on CoW Swap.

Fairblock, a modular encryption infrastructure provider, and Anagram, a crypto venture studio, have launched FairyCoW Swap, an auxiliary application that adds encrypted order protection to CoW Swap’s decentralized trading protocol. FairyCoW lets users submit time‑locked encrypted limit orders to CoW Swap so that order details remain hidden until a specified decryption time, reducing the risk of pre‑trade information leakage and related MEV strategies like frontrunning and sandwiching. The system uses Fairblock’s programmable encryption stack—centered on its FairyRing infrastructure—to handle encryption, key management, and conditional decryption without exposing order data to validators, relayers, or even Fairblock itself before the unlock time. The collaboration showcases Fairblock’s approach of providing “plug‑in” pre‑execution privacy that can be layered onto existing DeFi protocols rather than requiring a new privacy chain or custom infrastructure. For CoW Swap users and market makers, encrypted limit orders are designed to improve capital efficiency by enabling more confident placement of resting liquidity while mitigating information asymmetry and predatory order‑flow strategies. More broadly, FairyCoW functions as a public demonstration of Fairblock’s modular privacy tools—such as identity‑based encryption and conditional decryption—potentially paving the way for similar integrations across other DEXs and onchain applications that are seeking MEV resistance and fairer price discovery without relying on centralized intermediaries.
