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 Pantera Capital, 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.
'With this latest raise, Zama becomes the world's first unicorn in the FHE space, which is a major milestone for the industry. Reaching a $1 billion valuation represents a significant increase that reflects the market's confidence in our FHE technology and our team's ability to deliver confidentiality to financial applications onchain' said Dr Rand Hindi, CEO and co-founder of Zama.
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.
Ken Seiff, Co-Managing Partner of Blockchange Ventures, said: 'Not since I first saw Ethereum in 2014, have I seen a company commercializing an entirely new technology that could be as foundational to our global technology infrastructure. As finance moves onchain and regulations tighten globally, public blockchains are likely to be the first beneficiaries of what Zama is building. But the opportunity goes well beyond that, as industries such as health care, defense, and virtually all others that use cloud computing could massively benefit from the stepchange in confidentiality and compliance pioneered by FHE, and in particular, Zama.'
"Zama's FHE protocol launch is a cryptography milestone. By enabling efficient, developer-friendly FHE, Zama unlocks secure, compliant, and verifiable dApps for AI, crypto, and cloud,' said Paul Veradittakit, Managing Partner at Pantera. 'The protocol paves the way for onchain identity, financial, and consumer applications—previously out of reach for developers."
Zama's FHEVM makes it possible to run confidential smart contracts on encrypted data, 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.
'This round also underscores a broader shift: confidentiality is no longer a niche concern—it's a foundational requirement. The broad adoption of blockchain in finance is driving demand for secure, confidential computing technologies,' said Hindi.

Ika Core Contributor dWallet Labs Reveals REFHE: First FHE Scheme That Works Like a Real CPU
dWallet Labs, a core contributor of Ika, and a leader in cryptography and decentralized security, today announced REFHE (Ring-Enhanced Fully Homomorphic Encryption), a new encryption scheme that brings encrypted computation closer than ever to how real processors work. REFHE uniquely supports both arithmetic and logical operations on encrypted 64-bit values, enabling software to switch seamlessly between math and logic —just like a modern CPU. Why This Matters Fully Homomorphic Encryption (FHE) allows computation on encrypted data without revealing the underlying information—a capability long considered a 'holy grail' of cryptography. But existing schemes typically force a trade-off: choose between efficient arithmetic or efficient logic. REFHE removes that barrier, creating a unified approach where real-world software—full of mixed arithmetic and logic—can run encrypted. Breaking a Decade of TFHE Dominance Since 2016, TFHE has been one of the most widely used FHE schemes, especially in the context of blockchain use cases, and is leveraged by companies such as Zama. For nearly a decade, no scheme had meaningfully surpassed its performance and latency—until now. REFHE delivers: 100× smaller ciphertexts 20× faster multiplications 1,000× faster additions These gains, alongside being optimized for both arithmetic and logical operations, make it the first FHE scheme capable of operating as a practical, CPU-like encrypted execution engine. Implications for 2PC-MPC and the Ika Network The latest FHE-related research, including REFHE and Threshold FHE, can be integrated into the 2PC-MPC protocol powering the fastest MPC network - Ika, coordinated on Sui. With these breakthroughs, 2PC-MPC could directly execute its Zero-Trust signing with FHE, reducing communication rounds and boosting latency, throughput, and security. Building on Recent Threshold FHE Breakthroughs REFHE follows dWallet Labs' recent Threshold FHE research, which enables scalable, efficient, secure multi-party decryption. Together, these advances form the basis for encrypted systems that are both high-performance and capable of real-world program logic. "This is more than a speedup," said Omer Sadika, Co-Founder of Ika and CEO at dWallet Labs. "It's about finally aligning encrypted computation with the way real software and CPUs work. That opens up a new class of secure, privacy-preserving applications that were simply not practical before." About Ika Ika is the fastest parallel MPC network, offering sub-second latency, unprecedented scale and decentralization, and zero-trust security. As the premier choice for interoperability, decentralized custody, and chain abstraction, Ika is set to revolutionize digital asset security and multi-chain DeFi. Users can learn more here dWallet Labs is at the forefront of cryptographic innovation, building secure, decentralized protocols for the next generation of the internet. From pioneering 2PC-MPC to advancing FHE, the company is shaping the infrastructure for a secure, interconnected world. Contact Ika PR Ika
