# How to use a Trezor on Hyperliquid without connecting it every time

Updated: 28 September 2026

Authorize a Hyperliquid API wallet with your Trezor once, then store that API key in Coldfront, a free Chrome extension. Coldfront gives the API key to the official Hyperliquid app while it's unlocked, so you trade from your Trezor's account without connecting the Trezor. Withdrawals still need the Trezor.

This works with the Trezor Safe 3, Safe 5 or Model T, and with any Trezor that can sign for an Ethereum account.

## Connect your Trezor to Hyperliquid

In MetaMask or Rabby, add the Trezor as a hardware wallet. A Trezor window walks you through connecting it and choosing the account. Then open app.hyperliquid.xyz, press Connect, and pick that browser wallet.

When Hyperliquid asks for a signature, the Trezor shows it on its own screen. Check it there before you confirm.

## Why the Trezor has to be connected in the first place

Hyperliquid runs in the browser, so the Trezor reaches it through a browser wallet. The app asks the Trezor to sign when you enable trading, when you enable trading again in another browser, and when you withdraw or move funds. That keeps your funds safe, but it also means a browser wallet connected to a trading site and the device close by. A connected wallet is also how most Hyperliquid scams start: a fake site, a connect prompt, and one signature.

## Trade without connecting the Trezor

1. **Authorize an API wallet with your Trezor.** Open [app.hyperliquid.xyz/API](https://app.hyperliquid.xyz/API) with the Trezor connected. Enter a name, press Generate and copy the private key it shows: that's the API key, and it's shown once. Press Authorize and confirm on the Trezor.
2. **Store the API key in Coldfront.** [Install Coldfront](https://chromewebstore.google.com/detail/ijhlfmhnpbgknhabconhepgdaabaeogg), paste the API key, and pick a passphrase. Add Touch ID (passkey) if you like. Coldfront shows the API wallet address it worked out from the API key, so you can check it matches the API page.
3. **Disconnect the Trezor and trade.** Disconnect the browser wallet from Hyperliquid and put the Trezor away. Unlock Coldfront, open app.hyperliquid.xyz, and trade as usual. The official app shows your Trezor's account and signs orders with the API key.

Coldfront locks after the time you choose, when your computer goes idle, or when you close the last Hyperliquid tab. Locking reloads every Hyperliquid tab, so the app forgets the API key.

## What the Trezor still signs

- Authorizing the API wallet, and renewing it (it lasts up to 180 days).
- Withdrawals.
- Moving funds between accounts.

## Before you start

Coldfront is free and works with Hyperliquid accounts that joined with Hyperliquid referral code COLDFRONT, which takes 4% off your trading fees. Hyperliquid accepts a code only before an account's first trade, so if your Trezor account has already traded, add a second account on the Trezor and follow the [new account guide](https://cold-front.xyz/guides/new-account/).

## Questions

### Can I use a Trezor on Hyperliquid?

Yes. Connect the Trezor through a browser wallet such as MetaMask or Rabby and it controls a normal Hyperliquid account. To trade without connecting it every time, authorize an API wallet with it once and use Coldfront.

### Does the Trezor need to be connected while I trade?

Not with Coldfront. The Trezor signs once to authorize an API wallet. After that, Coldfront gives the API key to the official Hyperliquid app while it's unlocked, and the Trezor can stay disconnected until you withdraw or renew the API wallet.

### Can Coldfront withdraw from my Trezor's account?

No. The API key Coldfront holds can place, change and cancel orders. Hyperliquid doesn't let an API wallet withdraw, send, transfer or approve other wallets, so those still need your Trezor.

### What if I lose my Trezor?

Your Hyperliquid account belongs to the address, not the device. Restore your recovery phrase on a new Trezor (or another wallet) and you have the account back. The API wallet keeps working until it expires or you revoke it, but withdrawals need the restored wallet.
