What is Sealed?
Sealed is a privacy-first messenger where message content is end-to-end encrypted, while fees and source code are publicly verifiable on blockchain.
Support & Setup
Frequently Asked Questions
Sealed solution ensures total privacy by enabling communication that cannot be monitored, tracked, or accessed by any third party.
Can anyone read my messages?
No. Messages are encrypted on your device and can only be decrypted by the intended recipients. Not even Sealed can read them.
What data is stored on the blockchain?
Only encrypted message envelopes, payment records, and protocol parameters. Message content and user identities are never public.
Does Sealed know who I am talking to?
No. Sealed does not have access to your contact graph. Each message is delivered to a unique, non-linkable destination.
Why does sending a message cost money?
Messaging on Sealed is paid because each message is a real transaction on the blockchain, so it comes with a gas fee. A transparent application fee also prevents spam, removes ads and data monetization, and allows Sealed to operate without central servers.
How much does a message cost?
The cost depends on your selected tariff or subscription and is calculated per 2 KB of encrypted data. The exact price is always shown before sending.
Are message sizes or metadata exposed?
No. Messages are padded to fixed-size blocks, making it difficult to infer content or intent from message length.
What happens if I lose my phone?
You can instantly revoke the lost device. It will no longer be able to decrypt any new messages and your seed phrase wallet works like a backup.
Can I use Sealed on multiple devices?
Yes. Each device has its own cryptographic keys and can be independently added or removed from your account.
Are my messages stored on Sealed servers?
No. Sealed does not operate a central message database, instead we use a public blockchain chosen by the user. Messages exist only in encrypted form and are readable exclusively by participants.
Is Sealed suitable for private or sensitive conversations?
Yes. Sealed is designed for situations where confidentiality and minimal metadata exposure are critical.
Does Sealed rely on trust in a central operator?
No. Security is enforced cryptographically, and protocol rules are verifiable on-chain rather than enforced by policy.
Do I need technical or crypto knowledge to use Sealed?
No. All cryptography and blockchain interactions are handled automatically in the background.
What is the Sealed utility token used for?
The token is used for staking, participating in protocol incentives, and sharing in application-level revenue share.
Do I need the token to send or receive messages?
No. Messaging functionality does not require holding the token.
How does staking the token work?
Stakers lock their tokens in a smart contract and receive a proportional share of messaging fees distributed by the protocol.
Where do staking rewards come from?
Rewards come directly from real usage fees paid by users, not from inflation or emissions and paid out in blockchain's native currency.
Does the token affect message privacy or encryption?
No. Token ownership has no impact on encryption, access to messages, or user privacy.
Can Sealed share my conversations with anyone?
No. Sealed cannot share message content with anyone because it does not have access to it. Messages are end-to-end encrypted and only participants hold the decryption keys.
