Messages on the blockchain — only for those who are meant to see them.
Stegachain is a platform for private data transfer: we combine encryption with blockchain recording. The sender encrypts a message with a secure key, the message is embedded into a transaction, and the recipient extracts and decrypts it locally. Metadata is minimal, and only those with the key have access to the content.
StegaChain makes blockchain messaging simple and secure. Every message is encrypted, stored on-chain, and can only be read with the right key. Here’s a step-by-step guide to how it works:
You sign up with an invite code (during the alpha stage). A new blockchain wallet is automatically created for you — your MetaMask or Trust Wallet is not required.
After login, you enter your personal dashboard. By clicking your profile icon, you can copy your wallet address and access the Faucet.
To test the system, you can claim 0.2 MON tokens every 12 hours using the Faucet. These tokens are used to pay for blockchain transactions inside the platform.
You generate a cryptographic key directly in your dashboard. This key is unique and must be stored securely — it is required for both encryption and decryption of your messages.
Write your message and click Encrypt. The system transforms it into unreadable ciphertext that cannot be interpreted without your key.
By pressing Send Message, the encrypted text is written into a blockchain transaction. You receive a confirmation with the transaction hash.
To allow someone to read your message, you share your generated key with them. Without this key, no one can decrypt your messages — not even us.
The recipient opens the READ tab, enters your wallet address, and provides the shared key. The system fetches your encrypted messages directly from the blockchain.
Using the provided key, the ciphertext is decrypted locally in the browser. The recipient sees the original message — and no one else has access to it.
