Railgun is a set of smart contracts providing shielded transfers and private DeFi interactions on Ethereum and other EVM-compatible chains. It uses zk-SNARKs to maintain a UTXO-like note system (commitments and…

Renegade

Renegade is a decentralized dark pool protocol for trading digital assets. It combines maliciously-secure MPC (for private order matching) with zk-SNARK proofs (for verifiable settlement), ensuring balances, orders, and…

Shutter

Shutter Network provides encrypted-mempool infrastructure that prevents MEV extraction and front-running by encrypting transactions until they are included in blocks, using threshold cryptography for decryption. It is…

Soda Labs

Soda Labs develops open-source Garbled Circuit-based SMPC (Secure Multiparty Computation) tools that enable confidential smart contracts and encrypted data processing directly on EVM-compatible networks. The Garbled…

Space and Time

A SQL data oracle which is ZK-verifiable onchain. Space and Time allows smart contracts and API clients to run SQL queries over verifiably correct (attested), onchain events or signed, tamperproof offchain data and…
