Browser extension

Seal, in every Solana app.

The extension puts your sealed-key wallet inside your browser, so you can connect to any Solana site — and every signature still waits for your Approve. Here's how it works before you install anything.

Your key is sealed
The extension creates your key inside the browser, locked so it can sign but never be read or copied out — by anyone.
It shows up everywhere
On any Solana app — Pump.fun, Jupiter, Raydium, Magic Eden — Seal appears in the connect list like any other wallet.
Every signature asks you first
When a site wants a signature, you get a notification and the popup shows exactly what's being signed. Approve or Reject — nothing happens without you.
Optional 2FA
Add a 6-digit code from your phone on top of every approval, so someone at your computer still can't move funds.
Install in 2 minutes
