The scenario
A decentralized exchange (DEX) wants to offer institutional clients a private order matching service, similar to a traditional dark pool, to reduce market impact and protect large orders from front-running and MEV (Maximal Extractable Value) attacks. The challenge is to achieve this confidentiality on a public blockchain while maintaining verifiability and avoiding counterparty risk.
S Lab’s approach
S Lab implemented a dark pool solution using its confidential execution engine. Orders are encrypted client-side and submitted to the chain. The engine privately matches orders using zero-knowledge proofs to verify trade conditions without revealing order details. Once a match is found, atomic settlement occurs on-chain, ensuring self-custody and eliminating counterparty risk.
Designed to expose execution functionality without revealing sensitive trade intent or details.

The scenario
An OTC desk wants to offer institutional clients a private onchain order matching and atomic settlement service. Traditional OTC settlement faces three core issues: manual and delayed coordination between parties, counterparty risk in the absence of atomic escrow, and full onchain transparency that exposes identities and trading strategies. The challenge is to enable confidential matching with verifiable, atomic settlement on a public blockchain, while minimizing coordination risk and removing the need for trust between counterparties.
