zkBob

zkBob is a zk-based privacy application that works with the BOB stablecoin. We’ve introduced a new Direct Deposit functionality into zkBob, where BOB can be sent directly from a smart contract on Polygon or Optimism into the privacy pool.

We want you to use direct deposits to build out use cases where responsible privacy is preferred 🔥

• 🥇 1st prize - 5,000 BOB
• 🥈 2nd prize - 2,000 BOB
• 🏅 Notable projects: pool of 3,000 BOB will be evenly distributed among all other notable submissions

Ideas for implementations

• Integration within open-source wallets
• Apps for DAO accounting
• Browser extension for zkBob
• Donation/fundraising/tipping apps
• Privacy for P2P micro-transactions
• Integration with DEXs/bridges/aggregators

We are also open to novel use cases which make sense for privacy-preserving transactions

Acceptance Criteria

• Creativity, novelty, usefulness for end users and implementation quality.
• Importance of zkBob integration to the overall application/product (i.e. is it integral to app functionality, usefulness and purpose or is it an add-on without a lot of added value).
• Coherent integrations between zkBob and other existing protocols/dApps are appreciated
• Alignment with the BOB and zkBob ecosystem values of on-chain privacy protection within accepted limits.
• Incorporate some UI functionality so that users can send BOB privately through a browser or mobile based application.
• *extra credit will apply to solutions using other zkBob components on top of integration with direct deposits (zkBob SDK libraries, gift cards, compliance tooling, deep smart contract integrations, etc.)
