Connecting a wallet

sea.codes uses the Solana Wallet Standard so any wallet that advertises itself (Phantom, Solflare, Backpack, Glow, OKX, Trust, Coinbase Wallet, etc.) shows up in the connect modal automatically. Hardware wallets (Ledger/Trezor) are intentionally excluded — their native USB bindings break serverless builds.

SIWS — Sign In With Solana

After connecting, you sign a short SIWS message (Sign in to sea.codes). This is purely off-chain — no SOL spent, no transaction. The signed message becomes an encrypted iron-session cookie that lasts seven days.

Stuck session

If a session goes stale: open the wallet menu in the top-right →Sign out, then sign in again. The server will issue a fresh nonce.
