Get the extension Fluid with Locker Protocol Wallet
Fluid is a lending and borrowing protocol on Ethereum.
Use Fluid 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 Fluid site, not a copy of it. On 2026-09-17, all five checks passed:
- 1Fluid lists the wallet in its connect menu, under "Locker Protocol Wallet".
- 2Refusing the connection leaves Fluid idle and grants it nothing.
- 3Approving it walks every window and signature Fluid asks for and reaches the working app.
- 4Reloading the page keeps the session without asking for a new approval.
- 5Disconnecting Fluid from the wallet's list of connected sites makes the page let go.
How to connect Fluid
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 Fluid, 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 Fluid 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.
Fluid and Locker: questions people ask
Is it safe to use Fluid 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 Fluid?
"Locker Protocol Wallet". That is the entry Fluid 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 Fluid 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 Fluid?
No. Using Fluid through the wallet costs only what Fluid 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.
