About this app

Sealsend is a secure messaging app for encrypted chat and protected email workflows.

The app uses wallet-based identity on the ION blockchain, a TON-compatible network, to help users exchange encrypted messages with trusted contacts. Users can create or import a wallet, add contacts through invitation links, and send encrypted direct chat messages.

Sealsend also connects to Gmail so users can view their inbox, compose messages, and send encrypted email packages to recipients with a blockchain address. Encrypted email support is designed for secure file/message exchange while keeping compatibility with the Sealsend ecosystem.

Key features:
- Wallet-based identity using ION/TON-compatible addresses
- Encrypted direct chat messaging
- Contact invitations and invitation import
- Gmail inbox connection and email compose support
- Encrypted email package creation
- Contact picker for encrypted email recipients
- Recovery phrase export for wallet backup
