WebAssembly App

WebAssembly App​

The WebAssembly version of cardano-addresses can be run directly in the browser. This provides a client-side address inspection tool that runs entirely in the user's browser without any server-side processing.

Live Demo​

The app is available at: https://IntersectMBO.github.io/cardano-addresses/browser/

Running Locally​

First, build the WebAssembly binary:

cd browser
./serve.sh

This will:

  1. Build the inspect-address WASM binary using nix
  2. Copy it to the browser directory
  3. Start a local HTTP server on port 8080

Then open http://localhost:8080 in your browser.

How It Works​

The app uses:

  • WebAssembly compiled from the Haskell library via GHC's WASM backend
  • @bjorn3/browser_wasi_shim to provide WASI compatibility in the browser

The browser app performs address inspection entirely client-side, ensuring sensitive data never leaves the user's device.
