Zama Developer Program Mainnet Season 4 - Bounty Track

Welcome to the Zama Developer Program - Bounty Track!

For this season, the challenge is to build a Confidential Prize Savings App — a production-ready, confidential version of PoolTogether: a "no-loss lottery" where users deposit tokens into a shared prize pool, the pool's yield is awarded as prizes through periodic draws, and deposits, balances, and winnings stay encrypted end-to-end using the Zama Protocol.

Requirements: * A functioning dApp, including: * Smart contract + frontend code base * Working demo deployed on a website

* A 3-minute video demo to pitch the project (Real-person pitch only. AI-generated video or voice will not be considered.)

* A thread or article published on X introducing your project.

Rewards: The prize pool for this challenge is 5,000 cUSDT in total for up to 3 winners:

The number of winners and reward distribution may be adjusted based on the quality of submissions. For example, if a single submission demonstrates exceptional quality and completeness, the entire 5,000 cUSDT prize pool may be awarded to that submission.

Submission deadline: September 5th, 23:59 AOE
