Why traders love Capsule: a USB browser that locks like a Ledger

You trade on PCs that are not yours. Capsule fits in about 15 MB on the same USB stick you already carry next to your Ledger. Double-click, unlock with a PIN or Windows Hello — the same gesture as waking the hardware wallet — then open the exchange or DeFi dashboard. When you unplug, the coworking PC does not keep your session. This is not a Ledger; it is the browser that travels and locks like a device, instead of a Chrome window left open.

Why this crypto browser clicks for traders

The same stick, two jobs: Ledger plus browser

The Ledger holds the keys and Capsule opens the sites. On the same USB stick you carry the browser (about 15 MB) for Binance, Coinbase, Kraken, a DeFi dashboard and an explorer, with the hardware wallet in your bag. There is no Chrome install on the hotel PC and no Google profile welded to the machine. Download Capsule, label the stick and clone it once the PIN is set. The USB-browser and portable-browser guides cover the physical media and folder architecture.

A lock before the first tab — the Ledger gesture

Before a tab exists, an Unlock prompt backed by PIN plus Windows Hello or fingerprint has to open. Traders already know that gesture from a hardware wallet: nothing opens until you confirm. Chrome opens like a window; Capsule opens like a machine. Auto-lock is available at 5, 15 or 30 minutes. On a borrowed PC this is not theatre — it is the gate before trading. The private-browser guide covers the broader session-lock vocabulary.

A vault for exchange logins; the seed stays on the Ledger

Komby Vault lives in the same folder as an encrypted file on this device, with autofill and a scam warning before every fill. You can import from Dashlane, 1Password, Bitwarden, Chrome and Firefox, which covers exchange accounts and long passwords. Capsule does not store your seed phrase and does not replace the Ledger — the seed stays on the hardware wallet. Capsule itself does not hold the master password; recovery runs through Authenticator rather than through a mailbox. The built-in Shield VPN (free countries plus PRO) is useful when you change networks. This is not Opera with a crypto marketing tile.

Where Capsule draws the line on purpose

Capsule is not a cold wallet, not a secure element and not “official Capsule MetaMask.” There is no promise that your Bitcoin lives inside Capsule. Serious traders separate the two sides: keys on a Ledger, browsing in a client they control and unplug. Capsule is the second half. The no-admin and no-install guides cover school or office PCs without administrator rights, and the 15 MB page covers the measurable size.

How to trade with Capsule on the stick

  • Download Capsule, copy it to a labelled stick, set PIN plus Hello before the first trip and clone the stick.
  • Keep the Ledger for signing. Capsule is for the sites. Never put the seed inside Vault or a tab.
  • The USB-browser, private-browser and no-admin guides cover the usual environments.
  • The Capsule home page summarises the product in one line.

FAQ

Does Capsule replace a Ledger?

No. Capsule is a USB browser that locks (PIN / Hello). The Ledger holds the keys. They complement each other on the same trip — different jobs.

Can I store my seed phrase in Capsule?

No. Never put the seed in Vault, a note, or a tab. Seed = hardware wallet. Vault = exchange logins and passwords.

Is Capsule a crypto browser?

Yes in the practical sense: exchange and DeFi sites from a locked USB stick, without leaving a profile on the host PC. ~15 MB. /download.

Does it work on a hotel PC with no admin?

Often yes: folder to copy, no installer, no admin password. If the PC blocks every unknown program, no portable will pass. /news/no-admin-browser.

How do I verify the real size?

Right-click the Capsule folder → Properties: about 15 MB. A competitor’s website number is not the size on your disk. /news/15mb-browser.

Do I still need Dashlane or 1Password?

Not for the local vault job: Komby Vault is built in (import Dashlane, 1Password, Bitwarden, Chrome, Firefox). Free Shield VPN in Capsule. /download.

Does the UI really move, or is that marketing?

Changelog 3.7 (dock, Stage Manager), 3.8 (instant tabs), 3.12 (snappier start). Chrome/Firefox do not ship this dock. /download.

Is Capsule the world’s first portable browser?

No — wrapped portables already exist. Capsule claims the first native portable browser: designed as a folder by Komby Limited, with PIN + Windows Hello lock. /download.
