Siid

SIID is a non-custodial Solana wallet with end-to-end encrypted chat — built so the natural overlap between "I just sent you SOL" and "let's coordinate the next trade" lives in one place, without depending on a centralized server.

WALLET (non-custodial)
• Your seed phrase is generated and stored locally, encrypted with PBKDF2-SHA256 (600,000 rounds) + AES-GCM-256.
• We have no copy of your keys and no recovery mechanism. We literally cannot move your funds.
• Send and receive SOL and any SPL token. Network fee only — SIID adds 0% on plain transfers.

CHAT (end-to-end encrypted)
• 1:1 messages use the Double Ratchet algorithm over an X3DH prekey bundle — every message has its own key.
• Group chats use MLS (RFC 9420) for tree-based key agreement that scales past two parties.
• Sealed-sender envelopes mean our relay routes ciphertext only — it cannot read what you send.
• No phone number, no email — talk to any Solana wallet by address or .sol name.

SWAPS & LIMIT ORDERS
• Best-price swaps via Jupiter aggregation across every Solana DEX.
• Place LIMIT orders directly in the extension — single, OCO (one-cancels-other), and OTOCO (one-triggers-OCO).
• Limit orders survive the popup closing. Fills push as OS notifications within seconds, even with Chrome minimized.
• A built-in trade-feed bot logs every fill, cancel, and expire as a chat-style timeline.
• Market 0.10% (.sol holders 0.05%). Limit-on-fill 0.05% (.sol holders free).

TRADE ALARMS
• A built-in bot watches your open limit orders and pings you on fill, cancel, or expire — even when the popup is closed.

CURATED dAPP DIRECTORY
• One-tap shortcuts to Jupiter, Raydium, Magic Eden, Tensor, Solscan, SolanaFM, Sanctum.

MULTI-WINDOW MODE
• Pop chart and chat windows out of the popup and pin them anywhere on your screen.

NO TRACKING
• No analytics, no Google Analytics, no Mixpanel, no Sentry.
• Relay logs anonymized connection events for rate limiting only, retained ≤24 hours.
• Open relay code; if SIID disappears tomorrow, anyone can spin up a replacement.
