RobinMail
Open inbox Mail for wallets · Robinhood Chain
Your wallet,
finally readable.
Write to any address or name.robin. Every message is signed by the sender's wallet and end-to-end encrypted in your browser. No account. No password. No phone.
One signature to sign in
Connect any EVM wallet and sign one readable sentence. Your inbox stays open for 24 hours. It can never move funds.
A name, not an address
Mint you.robin as an NFT on Robinhood Chain. People write to the name, the name resolves to your wallet. Every mint burns $RobinMail.
Mail you already know
Subjects, threads, reply and forward, drafts, labels, read receipts. Ask for USDG inside a mail and get paid from the inbox.
Under the hood
Signed by the sender.
Encrypted for the recipient.
Subject and body are encrypted in your browser with a key derived from your wallet, for the recipient and for you. The server stores ciphertext it cannot open. Each message also carries a personal_sign signature committing to a hash of the plaintext, so authorship is provable without revealing content.

Privacy
Your mail is none of our business.
Subject and body are encrypted before they leave your device, once for the recipient's key and once for yours. What reaches the server is ciphertext it has no key for.
Your encryption key is derived from a single wallet signature. No key file, no seed phrase to back up, nothing uploaded. Works with any EVM wallet, on any device.
The signature commits to a hash of the plaintext. Anyone can verify who wrote a message, nobody learns what it says unless you share a proof link yourself.
No analytics, no trackers, no email server, no phone number. Notifications never contain the subject. Read receipts stay between the two of you.
Stamps · new
Cold mail costs a burn.
Set a stamp price on your inbox. Anyone outside your contacts has to burn that much $RobinMail to reach you: a plain transfer to 0x…dEaD, verified on-chain before the mail is stored. One burn, one mail.
Hold or burn: an inbox can also set a holder pass, so wallets holding enough $RobinMail skip the stamp. Holders get a 🟢 💎 🐋 tier next to their name in every inbox.
Spam gets expensive. Serious people still get through. And every cold mail on RobinMail makes the supply smaller, forever. Contacts always write for free.
