At Zama, our mission is clear: to become the confidentiality layer of blockchains. We believe this is the last mile before mass adoption of blockchain as the backbone of global payments, finance, and government. Without privacy, institutions cannot—and will not—migrate their most critical operations onchain.
Today, we're taking a decisive step toward that future, and it involves our new partners at OpenZeppelin.
Zama is partnering with OpenZeppelin, the most trusted provider of open source standards for building secure blockchain applications, to bring production-ready confidential smart contracts to Web3 using Fully Homomorphic Encryption (FHE).
If we want financial institutions—large and small—to use Zama as the confidentiality backbone for all their services, we need to deliver a secure, reliable, and scalable mainnet that meets their stringent requirements. There's no better partner for this mission than OpenZeppelin, whose audited smart contract libraries and tools have become the gold standard for Ethereum and other blockchain platforms, securing over $27 trillion in total value transferred.
Rand Hindi, CEO at Zama said: "Blockchain has proven its value for moving money and enabling programmable finance. The next frontier is the digitization of public infrastructure, from identity systems to land registries. But none of these applications can reach their full potential without confidentiality. Financial institutions need transaction confidentiality. Citizens need data protection. Enterprises need competitive confidentiality. At Zama, we're developing the cryptographic infrastructure to enable fully confidential smart contracts while preserving the inherent benefits of public blockchains: decentralization, composability and verifiability. Our partnership with OpenZeppelin, whose smart contract standards secure 218 billions in digital assets, enables us to build confidential primitives with the security and auditability that institutions demand. Together, we're creating the confidential computing layer that will unlock blockchain’s next chapter.”
OpenZeppelin is developing an open-source Confidential Token standard interface, similar to the ERC20 but with encrypted balances and transaction values. OpenZeppelin has also developed the first implementation of that interface, using Zama’s FHEVM. The implementation contains contracts and utilities that use the FHEVM coprocessor, leveraging FHE’s main feature - secure computation directly on encrypted data - the FHEVM enables confidential smart contracts on EVM-compatible blockchains.

Jonathan Alexander, CTO at OpenZeppelin said “Our partnership with Zama and the creation of the Confidential Token Association mark a pivotal step in bringing encrypted smart contracts into production. Together, we’re defining a new open source standard—confidential tokens—that offers the simplicity and interoperability of ERC20, but with encrypted balances and private execution by default. This is the foundation institutions need to build securely onchain.”
Zama, Openzeppelin and Inco Network, also teamed to form the Confidential Token Association, to develop the Confidential Token Standard: an interface for empowering token standards such as ERC20 with confidentiality. This isn't just about adding privacy features; it's about making privacy the default.
This partnership unlocks the next generation of institutional adoption and onchain applications. When privacy becomes as simple as deploying a standard smart contract, we remove the last barrier preventing traditional finance from embracing blockchain technology.
All contracts will be open source, audited, and ready for production use. Because when it comes to the future of finance, privacy isn't optional; it's essential.
