Simple wallet address validator for validating Bitcoin and other altcoins addresses in Node.js and browser.
Updated 6/19/2017 - Added Aleph/ALE Validation
Forked from ryanralph/altcoin-address.
I forked it to remove all Node.js dependencies (crypro, Buffer etc.) to make it usable in the browser as well. I didn't use browserify to achieve smaller footprint, file size is 4.0 kB (minifed and gzipped).
npm install wallet-address-validator
<script src="wallet-address-validator.min.js"></script>
bower install wallet-address-validator
