About StellaChat
StellaChat is a messaging protocol built directly on Solana. Public rooms, invite-only groups, and direct messages — every one of them is a set of program accounts on the ledger, owned and signed for by your wallet. There's no account to create, no inbox sitting on someone else's server. Connect a wallet and you're already a participant in the protocol.
How it works
Connect a wallet
Any Solana wallet works — no sign-up, no account, no email.
Discover
Browse public rooms and groups. No wallet needed just to look.
Join or request
Rooms are open. Groups and DMs need the other side to say yes.
Chat
Every message is a signed, on-chain event — yours, permanently.
What you can do
Public rooms
Open membership. Anyone can join and post — messages are plaintext on-chain, since they're public by definition.
Groups
Invite-only. Requesting to join sends a note to the admins; they approve or reject. Group messages are encrypted so only members can read them.
Direct messages
A DM request's note is the first message. The recipient accepts or rejects before the thread becomes a live, end-to-end encrypted conversation.
Under the hood
One program, not one contract per group
Every room, group, and thread is a set of program-derived accounts (PDAs) under a single Solana program — not a separately deployed contract per group. Spin up a new room and you're paying rent on a handful of accounts, not deploying code.
The ledger is the backend
There's no API server and no database sitting between you and the chain. The client reads and writes Solana accounts directly — what's on-chain is the entire state of the app, always.
Sign once, chat freely
The first message you send in a room or group authorizes a local session key with a single signature. After that, routine messages sign themselves — no popup per message. Joining, requesting, approving, and anything that changes who's in — that still goes through your wallet, every time.
Client-side encryption
Group and DM content is encrypted in the browser — a signature from your wallet deterministically derives the keys, nothing is stored separately.
No avatars, ever
On-chain profiles hold an alias and nothing else. Avatars are generated from your address on the fly, never stored anywhere.
Currently on devnet
StellaChat runs on Solana devnet — the same account model, the same program, the same signatures a mainnet deployment would use, just on Solana's public test cluster while the protocol is still being built out. No real funds are at risk here.
