Zama Raises $57M in Series B to Bring End-to-End Encryption to Public Blockchains

• With new backing by leading U.S. blockchain investors, Zama becomes the world's first Fully Homomorphic Encryption (FHE) unicorn.
• Funding coincides with the announcement of the Zama Protocol, which enables confidential applications on any blockchain.
• From July 2025, developers can start building FHE applications on Zama's public testnet.

Zama , the open-source cryptography company building state-of-the-art Fully Homomorphic Encryption (FHE) solutions for blockchain, announced a $57 million Series B funding round co-led by U.S.-based investment firms Blockchange Ventures and bringing Zama's total funding to over $150 million, and its valuation to north of a billion USD. The new funding will support Zama's mainnet launch, ecosystem adoption, and research efforts to make financial applications built with FHE scale to thousands of transactions per second.

The timing of Zama's announcement reflects the accelerating demand within the finance ecosystem for technologies that enable confidential, scalable, and compliant onchain financial applications.

The funding coincides with the announcement of Zama's Confidential Blockchain Protocol and its public testnet in July 2025, enabling developers to build confidential applications through Zama's FHEVM, with support for other EVM chains and Solana to follow.

Zama's , guaranteeing both confidentiality and composability. Blockchain-native confidentiality unlocks several use cases:

• Onchain Finance: Zama enables financial institutions to securely use public blockchains for a range of applications, including confidential stablecoin issuance and payments, asset tokenization, compliance, and more.
• Confidential Tokens : The ability to keep balances and amounts encrypted onchain enables blockchain companies to distribute tokens confidentially. Investors, team members and other token holders no longer have to publicly disclose their ownership, allowing them to better manage their portfolio and reduce the risk of being targeted by hackers.
• Identity and Proof of Humanity: The ability to distinguish between humans and AI in onchain applications is essential to the security of onchain finance. With the Zama Protocol, application developers can verify whether a user is human, without disclosing their identity publicly.
• Network States : Zama enables onchain communities and network states to operate confidentially. From currency to identity, governance and registries, it now becomes feasible to run key infrastructure on public blockchains.

Zama will use the fresh funding to advance the field of FHE and further commercialize its accessibility to blockchain applications and beyond. Zama is actively addressing the core challenges that have historically held back FHE adoption:

• Speed : At current benchmarks, Zama's FHE technology is 100x faster than when the company was founded, and is now capable of supporting most onchain payment use cases. Zama is expecting its technology to be 100x more scalable within the next five years, allowing it to address the most demanding onchain applications.
• Hardware integration : Using GPUs enables Zama to scale to hundreds of transactions per second. Zama is working towards a dedicated hardware-accelerated chip to advance FHE performance, with the ultimate goal of reaching tens of thousands of transactions per second.
• Developer usability : Using Zama doesn't require learning new programming languages. Instead, developers can use Solidity and other existing languages, and deploy their applications on their preferred chain.
