The primary modification was to resolve recipient addresses using smart contracts (that we deployed to Polygon and Celo testnets) rather than DNS records. ``More info about the technical design can be found here: For the mobile inbox app, we used Swift ``UI and Firebase. The sender dashboard was built using ``````````````Next````````JS, wagmi, Tailwind, Daisy`UI, Rainbowkit.
