Status (October 2026): The ZAMA token launched on February 2, 2026, on Ethereum, BNB Chain and Solana, after a public auction (January 21 to 24, 2026) that cleared at $0.05 per token. Claims for community sale and auction buyers opened the same day. Zama rewarded its community through the Zama OG NFT: 5,500 NFTs split between Creator Program creators, Developer Program builders, beta testers and community contributors. Holders could buy in a community sale at the auction floor price and got a 5% auction bonus. We found no ZAMA airdrop for the testnet tasks below, and the demo app they used is now offline. The OG NFT claim page lists no deadline. Sources: Zama (token launch), Zama (OG NFT).
Key Takeaways
- Zama is an open-source cryptography company that builds state-of-the-art Fully Homomorphic Encryption (FHE) solutions for blockchains.
- Zama develops tools like FHEVM, a framework for confidential smart contracts on EVM-compatible blockchains, and open-source libraries such as TFHE-rs and Concrete ML, which support encrypted data computations for Web3 and AI, with a focus on speed (100x faster than five years ago) and developer usability via familiar languages like Solidity.
- Zama launched its Confidential Blockchain Protocol public testnet on July 1, 2025, allowing developers to build confidential decentralized applications (dApps) on Ethereum, with plans for Solana and other EVM chains in 2026; the company raised $57 million in a Series B round, reaching a $1 billion valuation, to support its mainnet launch and ecosystem growth.
- The ZAMA token launched on February 2, 2026, after a public auction in January. We found no ZAMA airdrop for the testnet tasks in this guide; Zama rewarded its early community through the Zama OG NFT.
Disclaimer: Crypto airdrops are promotional events where tokens are distributed to existing holders of a cryptocurrency or to individuals who meet certain criteria. While airdrops can be a way to acquire tokens at no cost, they also involve risks. There’s no guarantee that the airdropped tokens will increase in value, and there may be associated fees or requirements. Additionally, airdrops can be susceptible to scams and phishing attempts. Always exercise caution and verify the legitimacy of any airdrop opportunity before participating.
What Is Zama?
Zama is a Paris-based open-source cryptography company founded in 2019 by Dr. Rand Hindi and Dr. Pascal Paillier, specializing in Fully Homomorphic Encryption (FHE) solutions for blockchain and AI, enabling computations on encrypted data without decryption to enhance privacy in applications like confidential smart contracts and secure data processing.
With over $150 million raised, including a $57 million Series B in June 2025, Zama achieved a valuation exceeding $1 billion, becoming the first FHE unicorn.
How The Zama Testnet Campaign Worked
Their Zama Confidential Blockchain Protocol, launched alongside a public testnet on July 1st, 2025, supports confidential smart contracts on Ethereum-compatible blockchains via the FHEVM framework, with plans to expand to Solana and other EVM chains in 2026. Zama’s open-source tools, including TFHE-rs, Concrete, Concrete ML, and FHEVM, empower over 5,000 developers to build privacy-preserving applications in finance, healthcare, and identity verification, addressing FHE adoption barriers like speed and usability while leveraging GPU scaling and familiar languages like Solidity.
These were the testnet steps in July 2025. The demo app from step 2 is now offline, and we found no ZAMA reward tied to these tasks.
👉 STEP 1: Participants got Sepolia testnet ETH at https://faucet.quicknode.com/ethereum/sepolia.
👉 STEP 2: They went to https://portfolio.demo.zama.ai/ (now offline) and connected a wallet.
👉 STEP 3: They claimed test tokens from the app’s faucet.
👉 STEP 4: They used “Transfer” to send tokens to any address.
👉 STEP 5: In the Shield tab, they shielded USDZ into cUSDZ, its confidential version.
👉 STEP 6: They completed Guild quests at https://guild.xyz/zama.
👉 STEP 7: Zama now runs seasonal Developer Program bounties for builders; Mainnet Season 4 took submissions from July 30 to September 5, 2026. Watch the Zama blog for the next season, and check OG NFT eligibility only on Zama’s own claim page (claim.zama.org).
Zama & FHE Quiz
The quiz is designed to test knowledge about Fully Homomorphic Encryption and Zama’s contributions to the field. It’s hosted on platforms like Guild, where participants answer multiple-choice questions to demonstrate their understanding of FHE concepts and Zama’s technologies.
Completing these quizzes is often part of Zama’s broader community initiatives, such as the Zama Creator Program or onboarding quests, which encourage developers and enthusiasts to learn about privacy-preserving technologies.
The answers to these quizzes have been shared publicly by community members to help others participate in Zama’s ecosystem. The reported answers are:
- FHE Intro Quiz #1: B, A, C
- FHE Intro Quiz #2: C, A, B
- FHE Intro Quiz #3: A, C, B
