Practical overview

When it fits

Consider Lace when you want a wallet spanning Cardano, Bitcoin and Midnight, or when you need to inspect its mirrored app source. Use the repository's app-specific documentation for build details beyond the documented initial commands.

Who it is for

  • People seeking a wallet interface for Cardano, Bitcoin and Midnight.
  • Developers who want to inspect the TypeScript source for Lace's browser extension and mobile app.

Documented uses

  • Use a wallet across Cardano, Bitcoin and Midnight.
  • Inspect source snapshots and release information for Lace's extension or mobile app.
  • Build an app from a tagged source snapshot using supplied API credentials and platform tooling where required.
Before you choose

Requirements & limits

  • The repository describes Lace as available through browser extensions and mobile apps, including Chrome Web Store, Microsoft Edge Add-ons, Google Play and the App Store.
  • The public repository is a mirror rather than the development source of truth; direct pull requests are closed, with issues and contribution proposals offered as routes for feedback.
  • Local builds require service API credentials and will differ from official builds in credentials and downstream metadata.
  • The repository is licensed under Apache-2.0.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build a Lace app from a release snapshot

Prepare and build the browser extension or mobile app from a tagged release snapshot.

Before you start

  • A checkout of the Lace repository and a release tag such as lace-extension@2.0.0 or lace-mobile@2.0.0.
  • Node package tooling for the documented npm commands.
  • Your own API credentials for services such as Blockfrost, Maestro, PostHog and Sentry.
  • Platform tooling for the mobile build.

Steps

  1. Check out the relevant release tag, for example the command below or the command below.

    Documented command
    git checkout lace-extension@2.0.0
    Documented command
    git checkout lace-mobile@2.0.0

  2. Run the command below.

    Documented command
    npm ci

  3. For the extension, enter apps/lace-extension and run the command below.

    Documented command
    npm run build

  4. For mobile, enter apps/lace-mobile and run the command below, then use platform tooling.

    Documented command
    npx expo prebuild --clean

Expected outcome

A local build process for the selected app, using the repository's release snapshot and your own service credentials.

Guide limitations

  • The mobile prebuild step is followed by platform tooling; the repository points to app-specific READMEs for further build details.
  • Local output will not be byte-identical to official builds because credentials and downstream metadata differ.
