Embassy

A monorepo for embassy, a proof of passport protocol.

Embassy lets users scan the NFC chip in their government-issued passport. If the signature is valid, the user can generate a proof that can be verified onchain. We are using that proof to mint them a Soulbound Token (SBT) they can use to show that they indeed hold an official passport.

Roadmap

• ✅ Make sure we can actually verify that a passport signature is signed by the issuing country
• ✅ Modify the Next.js frontend of zkrsa in order to accept an endpoint that stores signature data from someone scanning their passports
• ✅ Get zkrsa working with the signature format we are able to retrieve from the Android app
• ✅ Contract to mint the SBT when proof is valid
• ✅ WalletConnect integration to get the address
• ✅ Let user send their proof onchain to mint the SBT
• ✅ Commit to minter address in circuit to avoid front-running
• 🚧 On-chain registry of CSCA pubkeys based on the official ICAO masterlist
• 🚧 Decompose the hashed eContent of the passport into the private user data and reconstitute them in the circuit
• ✅ Modify the Android app to let people send their signature data to the Next.js backend (and store it temporarily)
• 🚧 Safe Module to claim a Safe if holding the right SBT
