HoodChat for Robinhood Chain
Messages only your wallet can read
HoodChat is an encrypted messenger for crypto wallets. Paste any 0x address and send a message only that wallet can open. No phone number, no email, no server that can read it — and you can tip USDG in the same transaction.
- 1You write it in your browser
- 2It’s sealed to their key and yours
- 3Ciphertext is posted to Robinhood Chain
- 4Only their wallet can open it
A private line between two wallets
Sealed before it leaves
Messages are encrypted in your browser to exactly two keys — theirs and yours. The chain only ever stores ciphertext.
Tip in USDG
Attach a USDG tip to any message. It moves wallet to wallet in the same transaction — HoodChat takes no cut.
Your key comes from your wallet
There’s no password and no backup file. One signature becomes your encryption key, so the wallet you already secure is the only thing that can open your inbox.

Publish
One small transaction puts your public key on-chain so anyone can write to you.
- 4
Send
Paste any 0x address that has published a key and start writing. Add a USDG tip if you like.

Questions
What exactly is HoodChat?
A messenger where the address book is the blockchain. You write to a wallet address; your browser encrypts the message to that wallet’s published key and posts the ciphertext to Robinhood Chain. Only that wallet (and yours) can decrypt it.
Can HoodChat read my messages?
No. Encryption happens in your browser with a key derived from your wallet signature. That key is never uploaded, and there’s no HoodChat server in the message path — it goes straight to the chain.
What is public?
Which wallets talked, when, and the approximate size of each message (padded to 32-byte buckets). The words are not. If the connection itself is sensitive, use a fresh wallet.
What does it cost?
Only Robinhood Chain gas, paid in ETH — usually well under a cent per message. There’s no protocol fee, and the contract hard-caps any future fee at 1 USDG. Live numbers are in the docs under Costs & fees.
Can I message a wallet that hasn’t used HoodChat?
Not yet — there’s no key to encrypt to. HoodChat tells you when a wallet hasn’t published one and gives you a link to send them.
What if I switch devices?
Connect the same wallet and sign the same message. You get the same key and your full history decrypts.
Say it to one wallet. Nobody else.
Connect, sign once, and your encrypted inbox is open.
