Browser WASM

The browser build runs the Cardano wallet coin-selection algorithm in a web page. It uses the Haskell implementation extracted from cardano-wallet, compiled to wasm32-wasi, and runs fully client-side in the browser.

This keeps one audited Haskell implementation for native and browser use, without a JavaScript reimplementation of the selection algorithm.

Try the live demo:

The browser WASM asset is part of the v0.1.0 release:

The Browser Demo page describes the demo input format. The WASM Portability Audit records the portability work behind the build.
