Direct Deposits bounty detailed description:

Direct deposits allow end users, intermediary protocols and smart contracts to make private transfers directly to the receiver zk address. Any EVM-based workflow containing transfers supported tokens might be easily integrated with zkBob direct deposits on the smart contract level, with very little modification required on the UI side.

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

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 zkBob ecosystem values of on-chain privacy protection within accepted limits.
  • *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.)
