Locker Protocol Wallet

Air-gapped multi-chain wallet, drop-in MetaMask replacement. QR signing, works with any dApp. Keys never touch this device.

Locker Protocol Wallet: the web3 wallet whose keys never touch your browser Locker Protocol Wallet is a multi-chain wallet and a drop-in replacement for MetaMask, built on one rule: no private key, no seed phrase and no password that could derive one ever exists inside the extension. Signing happens on a separate offline device, the free Locker Vault, and travels back as a QR code. A compromised browser, a malicious dApp or a phishing page has nothing to steal. WORKS EVERYWHERE YOU ALREADY GO The extension announces itself to dApps through the standard wallet interfaces, so swaps, bridges, lending, NFT marketplaces and games connect to it like any other wallet. Any EVM-compatible network works out of the box, plus any custom network you add yourself. The major non-EVM ecosystems ride the same air-gapped QR signing, with coin control that keeps inscribed satoshis out of ordinary payments. EVERYTHING IN ONE PLACE Your holdings across every network appear on their own, with the portfolio total in your currency. Each account shows every address it holds, one per network, with its copy and its receive QR. Connected sites, address book, fee controls, speed-ups and cancellations work the way you expect. SWAP, BRIDGE, TRADE PERPS ON HYPERLIQUID Swap on the same network or bridge across networks and ecosystems with the best route found for you. Trade Hyperliquid perpetual futures directly from the wallet: markets, positions, take-profit and stop-loss, open and historical profit and loss, with a trading-only key your Vault authorizes for thirty days, unable to withdraw or transfer anything. Deposits and withdrawals are signed by the Vault itself. Move HYPE between your Hyperliquid spot balance and HyperEVM in two taps. Perps sit behind a risk disclaimer you accept once. A small service commission applies to swaps, bridges and perps, always shown on the summary before you sign. EVERY REQUEST EXPLAINED BEFORE IT LEAVES Transfers, approvals and typed data are decoded into plain language, in 16 languages, on the extension and on the Vault. Deterministic rules stop the dangerous shapes before the QR is even shown: unlimited spending approvals, collection-wide operator grants, tokens with no contract code, known phishing origins, account delegations. These, and only these, can ask for an explicit acknowledgement. An optional assistant, downloaded once at your request and running entirely on your device, adds a plain-language reading of unusual patterns, such as most of a balance leaving for an address you have never used. It is advisory by design: it can raise a warning, never lower one, and it never signs anything. Nothing about what you sign is sent anywhere. THE VAULT HAS THE LAST WORD The QR carries the raw request, never a verdict. Your offline device re-reads it and runs its own analysis, so a compromised computer cannot hide a warning from the screen that signs. NOTHING ABOUT YOU LEAVES YOUR DEVICE No account, no sign-up, no analytics, no telemetry. The extension talks only to the public nodes of the networks you use and, when you ask for a feature, to the service that powers it. Builds are deterministic: store reviewers rebuild the published package from the source and check it byte for byte. GETTING STARTED 1. Install the free Locker Vault on a dedicated offline device. An old phone works. 2. Scan its sync QR into the extension: your public addresses arrive, your keys stay. 3. Use any dApp as usual. When it is time to sign, scan the request into the Vault and scan the signature back. Your keys stay offline, forever.
