May 2026 Summaries

Season 3 of the Zama Developer Program introduces new opportunities for developers to build confidential financial applications using the Zama Protocol, which enables secure computation on public blockchains through Fully Homomorphic Encryption (FHE). This season continues popular tracks from previous seasons, such as the Builder and Bounty tracks, with the latter challenging developers to create a Confidential Wrapper Registry App for better integration of ERC-20 and ERC-7984 tokens. A new Special Bounty Track, in collaboration with TokenOps, encourages developers to design confidential token distribution applications. The ongoing Developer Bootcamp offers Solidity developers an educational program to build confidential dApps without prior cryptography experience. All participants are incentivized through cUSDT rewards, with projects judged on criteria such as UX, code quality, and production-readiness.

Developer programs, such as Mainnet Season 2, are designed to assist creators at various stages of project development, with a focus on building applications on the Zama Protocol that prioritize confidentiality in finance, prediction markets, and consumer applications. This season saw 234 submissions, culminating in 15 winners, showcasing projects that address the need for privacy and compliance in onchain operations. Notable projects include AttestRail for confidential compliance in onchain finance, Cipher21 for encrypted onchain Blackjack, and Circux for private savings circles. The innovations extend to developer tools, such as the FHEVM Skill Bundle, which enhances AI coding agents' ability to write confidential contracts. Special tracks also highlighted advancements in encrypted derivatives and synthetic stocks. The season underscores the growing importance of confidentiality in blockchain ecosystems beyond niche applications, emphasizing the integration of privacy into fundamental onchain activities and tools. As the program progresses into its third season, the focus remains on building confidential decentralized applications with rewards incentivizing participation.

Zama's acquisition of TokenOps aims to address the transparency issues in public blockchains by integrating Fully Homomorphic Encryption (FHE) into token lifecycle management, thereby making institutional transactions confidential. In public blockchains, transparency can be detrimental to institutions, as it exposes actions like vesting schedules and airdrops, leading to market inefficiencies such as price drops and front-running. By utilizing FHE, TokenOps allows for encrypted token operations on public blockchains while maintaining auditability for compliance, thus eliminating signaling risks and protecting strategic information. This integration allows major investors to manage distributions confidentially, aligning with regulatory standards without public disclosure. TokenOps, operating as an independent brand post-acquisition, continues to offer its confidential lifecycle solutions and plans to expand into full portfolio management. This move represents a shift towards programmable confidentiality in finance, providing a secure and profitable environment for global capital investments on public blockchains.

The Zama Protocol has recently undergone significant advancements, including a major upgrade that enhances both developer tooling and end-user infrastructure, such as the introduction of the Zama SDK and the Portfolio App for confidential finance. Institutional partners have moved into production, with 400+ enterprise clients now benefiting from encrypted onchain transactions for various financial activities. The protocol has expanded its reach with $ZAMA being listed on major exchanges, and support for multiple blockchains like Ethereum and Solana. The ecosystem is further enriched by initiatives like the Zama Builder Villa at EthCC[9] and the PL Genesis Hackathon, which highlight the growing focus on confidential onchain finance. As the infrastructure is now live and institutional integrations are in production, the application layer is also expanding, suggesting a future where confidential onchain financial transactions could become standard practice.

The Zama Protocol introduces confidentiality to public blockchains using Fully Homomorphic Encryption (FHE), aiming to transform blockchain technology akin to how HTTPS secured the internet. With the launch of the Zama SDK, developers can integrate confidential tokens into their applications without grappling with cryptographic complexities, offering familiar interfaces and tools for easier adoption. The protocol also implements delegated decryption, enabling confidential yet auditable transactions, crucial for institutional finance. Official ERC-7984 wrappers allow standard tokens to be converted into confidential equivalents, and a testnet faucet provides resources for developers. The mainnet launch includes a portfolio app for managing confidential tokens, staking options for community engagement, and token bridging across multiple blockchains. The focus now is on building innovative applications on this infrastructure, promising new possibilities in confidential finance.

Builder Stories is a series by Zama that features developers creating confidential applications using the Zama Protocol, with a spotlight on Patricia Ortuño Otero and Joaquin Trujillo, winners of the Zama Developer Program Mainnet Season 1. Their project, Paychain, is a non-custodial, GDPR-compliant payroll system leveraging Fully Homomorphic Encryption (FHE) to process encrypted data end-to-end on a public blockchain. This solution addresses the need for confidentiality in payroll systems, which often struggle with privacy issues when using public chains. Patricia, an expert in FHE since her student days, and Joaquin, responsible for implementation and UI/UX, emphasize designing from the ground up to maintain data confidentiality, aligning with GDPR principles. They highlight the shift from cryptographic challenges to legal and data protection complexities as the main hurdles in developing with FHE. The goal of Paychain is to showcase FHE's transition from experimental research to practical application, encouraging more developers to explore this technology through the Zama Developer Program, which supports innovative builders in creating real-world confidential computing solutions.

The PL Genesis: Frontiers of Collaboration Hackathon showcased the innovative potential of the Zama Protocol, with 51 out of 880 projects utilizing its technology to address various sectors such as confidential payments, onchain finance, governance, and decentralized networking. Noteworthy projects include DripPay, which offers a private payroll system on the blockchain; null402, a confidential lending platform using encrypted data; ZDrive, a trustless encrypted file-sharing service; Polaris, which provides private credit lines for Web3; and Confidential X4PN dVPN, a decentralized VPN ensuring private session metadata. These projects highlight the importance of confidentiality as a foundational requirement for real-world finance transitioning onchain. The hackathon emphasized the strong quality and practical utility of the projects, with Protocol Labs playing a pivotal role in organizing the event, underscoring the evolving landscape of blockchain technology towards greater confidentiality.
