Zama is an open-source cryptography company based in Paris, founded in 2020. It specializes in Fully Homomorphic Encryption, a breakthrough technology that enables computations on encrypted data without decryption. With a mission to make confidential computing fast and accessible for blockchain and AI developers, Zama is building the tools to secure the next generation of decentralized applications.
The Zama Confidential Blockchain Protocol is its latest innovation—a privacy layer enabling encrypted smart contracts on existing blockchains. After five years of development and a $57 million Series B round valuing the company at over $1 billion, Zama launched a public testnet to bring this privacy-first architecture to Ethereum and beyond.
Launched on July 1, 2025, the testnet provides access to developer tools, documentation, and ecosystem dApps. Builders can experiment with confidential smart contracts and position themselves for potential Airdrop rewards when the native $ZAMA token launches post‑TGE.
⚠️ Zama explicitly warns of scams, clarifying that no $ZAMA token exists yet.
About Zama
The Zama Protocol functions as a confidentiality layer for blockchains, starting with Ethereum. Symbolic execution occurs on-chain, while encrypted computations are processed off-chain using Fully Homomorphic Encryption. Threshold decryption with Multi‑Party Computation prevents any single entity from accessing sensitive data, as highlighted in the developer program.
This architecture enables encrypted transactions, private governance, sealed-bid auctions, and confidential identity systems. Developers can build with the FHEVM library in Solidity and interact via client SDKs. Scalability evolves from CPU-based coprocessors to GPU and ASIC-powered performance exceeding 10,000 TPS, detailed in the technical whitepaper.
With end-to-end encryption and Zero‑Knowledge proofs, the protocol supports secure DeFi, private DAOs, and compliance-friendly applications designed to meet real-world privacy needs.
