What needs to be done:

1. Port Openpassport contracts to Cairo leveraging Garaga
2. Update SDK to support Starknet contracts
3. Create a demo application showcasing the integration

An interesting exploration project might be combining Openpassport with account abstraction, e.g. for voting.

Consider the following sample application:

• A new app-specific account is deployed
• Initial state is "crowdfunding mode", people add donations to cover for the fees
• Once the accumulated balance is sufficient the state transitions to "Voting"
• People submit their vote by providing proof-of-citizenship without paying any fees! (we validate proofs during tx validation)
• We can potentially have multiple rounds
• When the voting period ends, votes are wrapped up
• The remaining budget might be reused in the next elections
