Zama Developer Program Mainnet Season 3: Composable Privacy Is the Key

Finance needs more than confidentiality to scale onchain. It needs composability. Using FHE, the Zama Protocol enables confidential computation on public blockchains, allowing developers to build applications and execute logic directly on encrypted data.

Across Season 1 and Season 2 of the Zama Developer Program, the community has been shipping: new confidential dApps, new tooling, and new integrations powered by the Zama Protocol.

The Zama Protocol unlocks financial use cases that were previously impossible on public blockchains: payroll, invoicing, investor distributions, and much more, as demonstrated throughout previous seasons.

What's New in Season 3

The Builder and Bounty tracks are back with two new challenges. This season's Bounty challenge: build a Confidential Wrapper Registry App that turns the official Zama Wrappers Registry into a usable product. For the Special Bounty Track, we're launching with TokenOps (recently acquired by Zama) to reward builders showcasing confidential token distribution using the TokenOps SDK.

The Bootcamp Track introduced in Season 2 is still open for sign-ups. The next cohort is planned for this summer.

All rewards continue to be distributed in confidential USDT (cUSDT).

In addition, participants are encouraged to share their project on X by tagging @zama and using the hashtag #ZamaDeveloperProgram.

Submission deadline: July 07, 2026 (23:59 AOE)

Builder Track

Build real-world use cases with the Zama Protocol.

Build a confidential dApp with smart contract and frontend, clear documentation, and a 3-minute video pitch. Deploy on Sepolia testnet or Ethereum mainnet.

Reward: 7,000 cUSDT in total, distributed across 5 winners: 2,500 cUSDT for 1st place, 1,750 cUSDT for 2nd place, 1,250 cUSDT for 3rd place, 1,000 cUSDT for 4th place, and 500 cUSDT for 5th place.

Bounty Track

Create templates and resources for the developer ecosystem.

This season's challenge: build a Confidential Wrapper Registry App. A production-ready app that surfaces every ERC-20 ↔ ERC-7984 wrapper pair on Sepolia, lets users wrap and unwrap any registry pair, decrypts any ERC-7984 balance through the EIP-712 user-decryption flow, and includes a Sepolia faucet for the official cTokenMocks.

Why this matters: today, many developers spin up their own ERC-20 testnet tokens and ERC-7984 wrappers instead of using the ones already in the official Zama Wrappers Registry. That fragments the ecosystem. The goal of this bounty is to turn the registry into a product every developer and user can point to.

Judged on coverage, correctness, extensibility, UX, code quality, and production-readiness.

Reward: 3,000 cUSDT for up to 3 winners. 1st place: 1,500 cUSDT. 2nd place: 1,000 cUSDT. 3rd place: 500 cUSDT. Distribution may be adjusted based on the quality of submissions.

Special Bounty Track × TokenOps

A dedicated track for confidential token distribution.

Public blockchains still leak sensitive financial data, making airdrops, token distributions, and team payouts hard to run confidentially at scale. This bounty asks developers to build the solution.

Create the best confidential application using the TokenOps SDK on the Zama Protocol. Your dApp should power a confidential airdrop or confidential disperse flow, with a polished frontend that makes confidential distribution feel effortless. Recipients should be able to verify and decrypt their own allocation, while distribution amounts and recipient lists remain confidential onchain.

Judged primarily on UX and frontend quality.

Reward: 2,500 cUSDT for the winning project.

Developer Bootcamp

Go from zero to building confidential dApps with FHEVM.

A 4-week cohort-based program led by a Zama-certified developer. Built for Solidity developers with no prior FHE or cryptography background. Cohort size is limited per cohort to ensure quality mentorship.

Prerequisites: Solidity experience required.

Sign-ups are still open. The next cohort is planned for this summer. There is no monetary prize; participants receive a completion certificate and hands-on FHE development skills.
