The Lace wallet,
living in your browser.

The Lace Wallet Extension is the lightweight bridge between a Cardano application and the assets you already own. One popup to connect, review and sign — with the keys never leaving your device.

Overview

What a browser wallet extension actually does

A wallet is not a bank account and it is not a website. It is a key holder that speaks to blockchains — and, in extension form, it speaks to the applications open in your browser too.

It holds the keys

Your recovery phrase and encrypted keys are generated and stored locally. Nobody on the other side of the connection can move funds for you — they can only ask for your approval.

It connects to dApps

The dApp connector exposes a small, permissioned API: a site can request a read, a connection or a signature. Each request lands in the extension, where you accept or reject it.

It shows you the trade before it happens

Fees, outputs, addresses and the network you are on should be on screen before you sign. Transaction awareness is the whole point of a wallet interface.

Capabilities

Everything in one popup

Six things a Cardano user reaches for most often, and how the extension approach changes each one.

dApp connector

Approve a site once and it can read your public address; every spend still needs a fresh signature from you.

Digital asset management

ADA and Cardano native tokens share one portfolio view, so balances and values stop being scattered across explorer tabs.

Staking & rewards

Pick a stake pool, see your delegation in one place and track reward history without moving the coins out of your own control.

NFT gallery

Collectibles are displayed as media rather than hex strings, which makes it far easier to spot a look-alike before you interact with it.

Multi-chain reach

Cardano remains the home network, with access extending to other ecosystems — including Bitcoin and Midnight — from the same interface.

Recovery & backup

One recovery phrase restores the wallet on a new device — which is exactly why it stays offline, on paper or metal, and never in a screenshot.

Setup guide

From install to first signature

Five steps that take about ten minutes — the careful ones are free and they matter most.

  1. 01

    Install only from the official listing

    Open the store page from the official project site and check the publisher name before you click Add. Sponsored search results are the most common route to a counterfeit build.

  2. 02

    Create a new wallet or restore an existing one

    A fresh recovery phrase is safest for a new user. Restoring is only for a wallet you already hold — and the phrase is typed into the extension, never into a website.

  3. 03

    Write the phrase down, then set a spending password

    Offline, in order, on two copies kept apart. The spending password unlocks the extension on this device; the phrase is what recovers the wallet everywhere.

  4. 04

    Connect a dApp and read the prompt

    The connection request lists what the site is asking for. Grant the minimum, and treat any request for your recovery phrase as the end of the conversation.

  5. 05

    Review the transaction, then sign

    Confirm the network, the recipient, the amount and the fee. A signature is irreversible, so the preview screen is the last line of defence you have.

Security & self-custody

What protects you — and what does not

An extension wallet moves responsibility from a support desk to the person holding the keys. That trade is worth it only with the habits to match.

Do this

  • Install from the official store page and verify the publisher.
  • Keep the recovery phrase offline, ordered, with a second copy apart.
  • Use a strong, unique spending password and lock the wallet when idle.
  • Read every connection and signature prompt in full.
  • Send a small test amount before a large transfer.
  • Keep the browser and extension updated.

Never this

  • Type a recovery phrase into a website, form, chat or email.
  • Photograph or cloud-store the phrase, and never paste it into a note app.
  • Approve a transaction you have not read, or a "validator" you just met.
  • Ignore an urgent DM asking you to re-sync, migrate or unblock a wallet.
  • Install a "helper" extension promising free tokens or faster rewards.
  • Trust a mirror domain because the logo matched.

Lace Wallet Extension: a practical guide to Web3 self-custody

Self-custody starts with a simple idea: the keys live with you. The Lace Wallet Extension puts that idea inside the browser, where the applications you use every day can ask for a signature — and where you decide whether to give one.

Installed as a browser extension, Lace becomes the bridge between a Cardano application and your own holdings. Rather than typing a recovery phrase into a website, you approve a request in a small extension window: connect, review, sign. Native tokens and NFTs share one portfolio view, staking preferences are set once, and every transaction is previewed with its fees and outputs before anything reaches the chain.

Because the wallet holds the keys rather than a company, the responsibility travels with them. Your recovery phrase is the wallet: whoever reads it owns the funds, and no support desk can undo a signature.

That is why the habits matter more than the interface. Install from the official store listing and verify the publisher. Keep the phrase offline, never typed into a chat, a form or a "validation" page. Read each prompt before approving it. Used that way, an extension wallet is a fast, transparent doorway into Web3 — powerful precisely because nothing is hidden behind a custodian.

FAQ

Questions people ask first

Is the Lace Wallet Extension custodial?

No. It is a self-custody wallet. Keys are generated and stored on your device, encrypted behind your spending password, and the recovery phrase is the only master copy.

Which browsers are supported?

It ships as a browser extension for Chromium-based browsers such as Chrome, Brave and Edge, and for Firefox. Install from the official store listing only.

Can a connected website move my funds?

No. A connection lets a site read your public address and request signatures. Every spend still needs your explicit approval in the extension, and you can revoke the connection at any time.

What happens if I lose my device?

Restore the wallet with your recovery phrase on a new device: the assets are on-chain, so nothing is lost as long as the phrase is intact. Without the phrase, a lost device means lost access.

Does this page collect my keys or hold funds?

No. This is an independent informational guide. It has no wallet functionality, no connection to your funds, and will never ask for a recovery phrase or a password.
