About
Empowering decentralized ecosystems with scalable zero-trust transactions
Zama is an open-source cryptography company delivering Fully Homomorphic Encryption (FHE) solutions to enable confidential smart contracts on any L1/L2. Its Zama Confidential Blockchain Protocol keeps on-chain data encrypted during processing, uses FHE coprocessors for scalability and low gas, and is Solidity-compatible—aimed at confidential DeFi, payments, banking, tokens, and real-world assets.
Use Cases
Confidential DeFi Transactions
Enables private token swaps and lending on blockchain with encrypted dataprocessing to protect user privacy.
Self-Custodial Banking
Supports confidential banking services where users maintain control of fundswith onchain encrypted transactions.
Real-World Asset Tokenization
Allows secure and private token launches and trading of real-world assets whilekeeping details encrypted onchain.
Sealed-Bid Auctions
Facilitates confidential sealed-bid auctions with encrypted bids processed onblockchain for fairness and privacy.
Key Features
FHE-based Confidentiality & Protocol Architecture
- Uses Fully Homomorphic Encryption (FHE) to keep onchain data encrypted duringprocessing.
- Enables confidential smart contracts on any L1 or L2 via coprocessors thatoffload FHE computation.
- Solidity-compatible developer experience; developers can use euint data typesto mark private fields.
- Performance targets: currently ~20 tps/chain, aiming for ~1,000 tps next year;FHE ASICs targeted to enable 10,000+ tps.
- Claims to provide security, decentralization, verifiability, composability,and scalability compared with MPC, ZK, TEEs, and private chains.
DeFi, Stablecoins & Ecosystem Adoption
- Enables confidential DeFi primitives such as confidential token swaps,lending, and yield farming with encrypted amounts.
- Supports confidential stablecoin transactions and onchain self-custodialbanking while keeping amounts private.
- Programmable compliance features allow contracts to specify who can decryptwhich data to meet regulatory needs.
- Targeted use cases include RWA tokenization, confidential tokenlaunches/vesting/governance, and sealed-bid auctions to prevent front-running.
- Active developer and ecosystem support: Devhub, documentation, GitHub, apublic testnet is live, and a roadmap toward mainnet.
