Let's clarify something about SealSend.
SealSend uses blockchain technology, but that doesn't make it a cryptocurrency project.
While we previously explored a tap-to-mine initiative, we decided to discontinue it due to its poor performance. No tokens were ever distributed, and we have no plans to pursue a token.
Our focus remains on what SealSend was built for: privacy, encryption, and secure communication.
Blockchain is a technology, not necessarily a cryptocurrency.
SealSend is a technology project, not a crypto project.
Are you still transmitting sensitive information via unencrypted email? If so, what is the reason for this practice?
I am even willing to share the encrypted message here, as no technology exists that could decrypt it. Consequently, even if this encrypted message contained a recovery phrase for a wallet holding 100 BTC, I would still make it public. Are you still transmitting sensitive information through unencrypted email?
These days, I would not do that!
Your phone number shouldn't be the key to your private life.
SealSend: end-to-end encrypted chat, groups & email.
🔒 No phone number or email to sign up
🔑 Your keys never leave your device
✍️ Every message signed

🩺 Test results with family. 🔐 A password or API key for a teammate (then rotate it).
Anything you'd hesitate to put in Slack, SMS or email.
👥 Cofounder and board chats.
Remove someone from a group and the group key rotates, so they can't read what's said next.
📵 SIM-swap proof by design.
No phone number means there's nothing for an attacker to port. Your identity is your wallet, and only you hold the 24 words.
💸 Crypto OTC deals: share your receiving address in SealSend.
Every message is signed by your wallet key and tamper-checked. A swapped address can't pass as yours.
🪪 Passport scans, tax forms, bank statements for your accountant or landlord.
Encrypted on your phone before they leave it. Not a plain attachment sitting in someone's inbox.
What it's built for 🧵
📄 Contracts, NDAs, term sheets. Send them as a SealSend Secure Email: AES-256 encrypted, signed, and we never touch your mailbox.
SealSend 1.0.6 is live on Android!
Encrypt messages and files, share them through your email or chat app, and decrypt in SealSend.
Now with ION + TON wallet support, a cleaner interface, and bug fixes.
Still completely free.

ION + TON support is here.
Create or import wallets for either network, manage both, and choose a default sender.
Encrypted sharing works ION → TON and TON → ION. Select the recipient’s correct network so SealSend can look up the right wallet.
Receiving is simple:
Open the received .sealsend file in SealSend, unlock the app, and decrypt it with the intended recipient wallet.
Forwarding the file doesn’t give someone else access. They need the matching wallet’s private key to decrypt the content.
Keep using the apps you already know.
Send the encrypted package through Gmail, another email app, WhatsApp, or a chat app that supports file sharing.
SealSend doesn’t need access to your inbox. You choose the recipient and confirm sending in your email or chat app.
