Get the extension 1inch with Locker Protocol Wallet
1inch is a swap aggregator that routes trades across many networks and exchanges.
Use 1inch 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 1inch site, not a copy of it. On 2026-09-17, all five checks passed:
- 11inch lists the wallet in its connect menu, under "Locker Protocol Wallet".
- 2Refusing the connection leaves 1inch idle and grants it nothing.
- 3Approving it walks every window and signature 1inch asks for and reaches the working app.
- 4Reloading the page keeps the session without asking for a new approval.
- 5Disconnecting 1inch from the wallet's list of connected sites makes the page let go.
How to connect 1inch
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 1inch, 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 1inch 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 Ethereum, the Vault decodes the call before you sign it: what it does, which token, and who it lets spend.
1inch and Locker: questions people ask
Is it safe to use 1inch 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 1inch?
"Locker Protocol Wallet". That is the entry 1inch 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 1inch 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 1inch?
No. Using 1inch through the wallet costs only what 1inch 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.
