A truly serverless messenger that uses the Stellar blockchain as its backend. Every message is encrypted with AES-256-GCM, stored on-chain, and self-destructs after 5 minutes. Send value or request payment. No phone number required.
Hey Product Hunt!
I'm Rodrigo Henrique, and I built XPENV because I realized that even "private" messengers still rely on central servers that can be hacked or subpoenaed.
What makes XPENV different?
It's a truly serverless Web3 messenger that lives entirely on the Stellar blockchain. Your identity is your crypto wallet—no phone number or email required. Every message is encrypted in your browser with AES-256-GCM, inserted into a blockchain transaction, and self-destructs forever after 5 minutes.
You can also use it for commerce, embedding payments or conditional charges directly into the message itself.
Today, I'm launching XPENV — the first self-destructing messenger with payments built-in.
I'd love to hear your thoughts on the future of private communication. Ask me anything!
Explanatory video about xpenv.com
Serverless messenger. Browser encryption (AES-256), stored in the MEMO field of the Stellar blockchain. Decryption key is only available for 5 minutes after a payment of approximately $1.10. After that, it disappears – not even the key owner can recover it. No metadata, no tracking. Only works on desktop with the Freighter extension. Useful for private keys, confidential documents, digital inheritance.
