SealSend - Secure Messaging

SealSend lets you encrypt messages and files, share them through your email or chat app, and decrypt received SealSend packages. It also includes encrypted direct chats and group conversations inside the app.

ENCRYPT, SHARE AND DECRYPT
Compose a message, choose the recipient wallet and optionally attach a file. SealSend prepares an encrypted package that you can share through a compatible email app or a chat app such as WhatsApp. The recipient opens the package in SealSend and uses the matching wallet to decrypt it.

USE YOUR EXISTING EMAIL OR CHAT APP
SealSend handles encryption and decryption. Your chosen email or chat app handles sending and delivery. You do not need to connect your Gmail account or grant SealSend access to your mailbox. Both sender and recipient need compatible SealSend software for encrypted packages.

CHAT WITH YOUR CONTACTS
Add trusted contacts using invitation links, exchange encrypted direct messages and take part in group conversations.

WALLET-BASED IDENTITY
Create or import an ION wallet to use as your identity. Protect access with an app PIN and biometric unlock on supported devices. Back up your recovery phrase and keep it private: it is required to restore your wallet.
