About
Mailchain was a Web3-native communication layer that let users send and receive private, end-to-end encrypted messages directly between cryptocurrency wallets and blockchain identities, removing the need for a traditional email address. Founded in 2021 by Tim Boeckmann (CEO) and Rob De Feo (CTO), the London-based startup built a single inbox spanning multiple wallet identities. The company permanently discontinued its service on 5 May 2026, deleting all user data and ceasing operations.
