Technical details

  • The Soulbound tokens and their characteristics: non transferable but burnable to avoid spam.
  • The Etherum standards we based the product on: ERC712 for signature verifications, ERC4973 for SBTs and contracts upgradeable with UUPS.
  • The signatures are stored off-chain and encrypted with Threshold cryptography thanks to Lit protocol, any sensitive data is encrypted that way as well.
  • Part of the data relevant to encounter goes on-chain when a user decides to mint the SBT to proof the encounter.
  • We built universal apps for web (nextjs) and mobile (ios, android).
