Four parts.
One extension.

It's a lot — but it's simple. Two foundations: your wallet and your chat. Everything else is built where they meet.

01
Wallet
Non-custodial. Your seed is derived and sealed in your browser — we hold zero copies.

Chat
End-to-end encrypted, wallet-to-wallet. No phone, no email — your address is your identity.

03
Trade
The moat where wallet meets chat. Swaps, limit orders, and trustless OTC — settled peer-to-peer.

Find the next coin and buy it in one tap. Alarms watch the chain for you — locally, in your browser.

Your seed never leaves your browser.

Two layers of cryptography stand between your seed and the world — and we hold neither key. No recovery server, no copies, no exceptions. Tokens, NFTs, live charts, and one-tap rent reclaim, all in a 380px popup.

02 · chat · end-to-end

Chat with a wallet.

No phone. No email. Message any wallet straight by its address — or a human-readable .sol name if it has one. You never need a .sol to use SIID. Sealed-sender envelopes mean nobody, not even us, can read what you send.

Set a price.
Walk away.

Limit orders that survive the popup closing. Set your price, shut the window, and get an OS notification the instant a fill lands on-chain — routed through Jupiter for the best execution.

04 · discover · runs local

Runs in your browser.
Not their server.

Find the next coin, buy it in one tap, and set alarms that watch the chain for you — all where they belong: on your machine, not someone else's.

others · their server
they see every wallet you watch
they go down — your alarms vanish

OS notification fires direct — no server in the loop
and it's all one terminal

A whole data terminal in the popup.

Markets, macro, news, on-chain flow and your own activity — polled in the background, rendered on your machine. Pick a feed.

One wallet, two desks.

Dock it as a side panel beside any dApp — or hit the expand arrow to blow it up into a full trading desk. Same wallet, same keys.

security · two layers, both yours

Locked on your device.

Your wallet seed is sealed before it's ever stored, and every message is sealed before it's ever sent. Tap through to see how each one works.

wallet seal

How your wallet password is stored

Your passphrase is stretched 600,000 rounds with PBKDF2, then used to seal your seed with AES-GCM-256. The sealed blob never leaves your machine — and only signed Jupiter instructions can ever touch it.

Your app encrypts every message end-to-end before it leaves your device. The relay only forwards the sealed envelope — it never holds a key, never learns who sent it, and drops an undelivered envelope after 21 days.

post-quantum handshake · PQXDH

Every conversation opens with a hybrid key exchange — so even a future quantum computer can't read what you send today.

01two locks
X25519 + ML-KEM-768
Classic elliptic-curve ECDH and post-quantum Kyber run side by side the moment a session opens.
02mixed key
Both secrets combined
The session key is derived from both — an attacker must break classical and quantum-safe crypto.
03future-proof
Harvest-now, decrypt-later safe
Even if today's ciphertext is stored and a quantum computer arrives, it still can't be opened.

questions

Good to know.

Yes. Your seed is generated and encrypted in your browser. We never receive it, store it, or hold a recovery copy. If you lose your seed phrase, no one — including us — can restore it.
No. Chats are end-to-end encrypted with the Double Ratchet (1:1) and MLS (groups), over a sealed-sender envelope. The relay only ever sees ciphertext and forwards it — it can't read content or see who's talking to whom.
Never. Your wallet address is your identity. Add a human-readable .sol name if you want, and friends can message you by it.
0% on plain transfers. Swaps range 0.05%–1.0%. .sol holders get market swaps at half-price and limit orders free. You always pay the standard Solana network fee.
v1.0 ships as a Chromium extension — the fastest path to a reliable background worker for limit-order alarms. iOS, Android, and dApp Seeker releases are planned next.
