What are you building?

Each role sets your scope before you see any code.

• Wallet

  The app holding the student's ID.

  You implement: an exchange client — POST, handle VPRs, return VPs.

  ~3 things, a few days

• Issuer (school)

  The registrar issuing the student ID.

  You implement: start an exchange, deliver a signed VC.

  small, separate piece

• Verifier (campus or partner)

  Whoever checks the ID — library, lab door, partner venue.

  You implement: request a presentation, verify the proof.

  small, separate piece

You do NOT need to implement the other two.
