Get the extension Jumper with Locker Protocol Wallet
Jumper is a swap and bridge interface built on LI.FI, tested here on its Solana side.
Use Jumper with a wallet whose private key never touches your computer: the site connects to the extension, and every signature is approved on a separate offline device.
Checked against the live site on 2026-09-17
We run the extension against the real Jumper site, not a copy of it. On 2026-09-17, all five checks passed:
- 1Jumper lists the wallet in its connect menu, under "Locker Protocol Wallet".
- 2Refusing the connection leaves Jumper idle and grants it nothing.
- 3Approving it walks every window and signature Jumper asks for and reaches the working app.
- 4Reloading the page keeps the session without asking for a new approval.
- 5Disconnecting Jumper from the wallet's list of connected sites makes the page let go.
How to connect Jumper
Install the extension and the Vault
Add Locker Protocol Wallet to Chrome or Brave, and set up the free Locker Vault on a spare phone that stays offline.
Choose "Locker Protocol Wallet"
Open Jumper, press its connect button and pick "Locker Protocol Wallet" in the list, then approve the connection in the extension.
Sign on the offline device
When Jumper asks for a signature, the extension shows a QR code. Scan it with the Vault, read the transaction there, approve it, and scan the answer back.
On Solana, each transaction is simulated before you sign it, and the programs it calls are named on the review screen.
Jumper and Locker: questions people ask
Is it safe to use Jumper with Locker Protocol Wallet?
The wallet cannot make any site safe, but it changes what an attacker can do: the key never touches the computer, every transaction is shown on the offline device before you approve it, and risky approvals and known phishing sites are flagged first.
Which button do I pick on Jumper?
"Locker Protocol Wallet". That is the entry Jumper showed for the wallet when we checked it on 2026-09-17. Sites change their menus, so if it has moved, look for Locker Protocol Wallet or the generic browser wallet entry.
Do I need a hardware wallet to use Jumper this way?
No. The key lives on the Locker Vault, a free app you install on a spare phone and keep offline. Transactions travel to it and back as QR codes, with no cable and no Bluetooth.
Does Locker Protocol Wallet add a fee on Jumper?
No. Using Jumper through the wallet costs only what Jumper and the network charge. The wallet's own fee applies to swaps and bridges made from the extension itself (at most 0.25%), shown before you sign.
