SealSend offers blockchain-backed encrypted messaging and sealed email
SealSend - Secure Messaging, developed by FUTUREFORGE LABS, is an Android app that replaces phone-number accounts with blockchain wallet identities for private communication. It combines end-to-end encrypted chat and an AES-256 encrypted 'sealed' email workflow that integrates with Gmail. The app targets privacy-focused individuals, Web3 users, and professionals who need locally encrypted messages and wallet-based identity management for sensitive conversations.

What is SealSend used for?
SealSend uses wallet-based identity on the ION blockchain to authenticate users without phone numbers, so recipients are identified by blockchain addresses rather than telephony identifiers. The app supports direct chat with end-to-end encryption and constructs encrypted email packages for Gmail, letting users send protected messages through standard mail infrastructure while keeping message content encrypted locally.
How private are your conversations on SealSend?
Privacy is implemented with a zero-knowledge architecture and AES-256 local encryption, meaning message content is encrypted on the device before any transmission. The developer does not retain readable message history, and recovery depends on a user-controlled recovery phrase, which serves as the only way to restore a wallet-based identity and access stored encrypted conversations.
Is SealSend easy to adopt and manage day-to-day?
Onboarding requires creating or importing a decentralized wallet and optionally enabling biometric authentication for local access, which introduces extra setup compared with phone-number apps. Notification controls and local storage of contacts and history are present; however, the wallet identity model changes typical contact discovery and requires users to manage recovery phrases and wallet addresses for communication.
How does SealSend work across devices and email workflows?
SealSend stores messages locally on the Android device and supports identity export via a recovery phrase for migration, so cross-device continuity depends on secure transfer of that phrase. The app integrates with Gmail by producing encrypted 'sealed' email packages, allowing encrypted content to travel through standard email systems while remaining unreadable without the corresponding decryption key.
SealSend suits privacy-minded communicators who accept blockchain identities
SealSend is a practical option for privacy-conscious users and Web3 participants who need encrypted chat and protected email exchanges tied to wallet-based identities. A notable consideration is the nonstandard onboarding: using a decentralized wallet and safeguarding a recovery phrase requires more technical care than phone-number accounts. The app suits anyone prepared to manage wallet keys for stronger local encryption and identity control.
