Aztec Rollup
Aztec is a privacy focused rollup (or zk-zk-rollup) on Ethereum that enables private transactions and programmable privacy. It is a fully programmable network where applications can access both private and public state.
Chainlink ACE
Modular compliance layer built on the Chainlink Runtime Environment (CRE) to define, execute, and enforce identity- and policy-based controls for digital assets across public and private chains. Core onchain components…
Curvy
Curvy is a smart-contract-/wallet-based privacy layer for ERC-20 transfers (and other tokens) on EVM chains. It introduces stealth addresses, view keys, and one-time addresses per transaction to break linkability of…
EY
A production-ready Zero-Knowledge rollup for private token transfers with enterprise compliance features. Nightfall v4 implements a ZK rollup that provides immediate finality and supports ERC20, ERC721, ERC1155, and…
Fairblock
Fairblock provides confidential balances and transfers for assets (e.g., stablecoins) that remain issued and liquid on an originating chain (e.g., EVM networks), while confidentiality logic executes on FairyRing, a…
Fireblocks
Fireblocks is a custody and infrastructure platform that provides secure wallet management and transaction workflows for institutions. In addition to custody and settlement rails, Fireblocks supports tokenization…
Flashbots
Flashbots develops MEV infrastructure including private mempools, block building, and SUAVE (Single Unifying Auction for Value Expression) - a decentralized platform for private intent expression and execution.
Hinkal
Hinkal is a smart contract on public chains that lets users hold private balances controlled through their existing wallet keys. This enables users to send, receive and operate in stablecoins confidentially, without…
iExec
iExec provides privacy-preserving computation, data governance, and trusted execution for decentralized applications through a decentralized network of Trusted Execution Environments (TEEs).
Orion Finance
Orion Finance enables private, onchain portfolio management by integrating confidential smart contracts powered by advanced cryptography (FHEVM). Managers can run encrypted strategies, protecting their alpha while…
Paladin
Open-source (Apache-2.0) privacy layer under the Linux Foundation Decentralized Trust. Paladin provides the common wallet/vault functions that are needed to interact with all forms of privacy preserving smart contracts…
Peer
Peer (ex-ZKP2P) is an open-source protocol that enables peer-to-peer fiat-to-crypto swaps by proving fiat payments were completed on instant payment rails (Venmo, Revolut, and others). V3 uses a modular verification…
Privacy Pools
Privacy Pools is a smart contract protocol that extends the mixer model by allowing users to prove that their withdrawals come from (or do not come from) deposits belonging to a specific association set. Instead of…
Product Fhenix
Fhenix builds a CoProcessor that brings Fully Homomorphic Encryption (FHE) to EVM chains, enabling developers to compute directly on encrypted data without ever decrypting it. This allows dApps to offer on-chain privacy…
Railgun
Railgun is a set of smart contracts providing shielded transfers and private DeFi interactions on Ethereum and other EVM-compatible chains. It uses zkSNARKs 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 zkSNARK 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.
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…
TACEO Merces
TACEO Merces is an implementation of Private Shared State (PSS) for confidential stablecoin transfers on EVM chains. It combines multi-party computation (MPC) with zero-knowledge proofs (Groth16 via co-SNARKs) to hide…
TX-SHIELD
TX-SHIELD builds modular privacy layers/solutions for institutional finance and AI systems:
Vendor/Pattern: Miden
Polygon Miden is a privacy focused Ethereum rollup (zk-zk-rollup) that prioritizes throughput and privacy over full EVM compatibility. It uses the Miden VM, a STARK-based virtual machine designed for client-side proving.
Zama
