<p>I'm looking for a JS library that can validate BIP16 <a href="https://en.bitcoin.it/wiki/Pay_to_script_hash" rel="nofollow">P2SH</a> addresses.</p>

Is there a JavaScript library for validating P2SH addresses?

I looked at [coinstring.js](http://cryptocoinjs.com/modules/currency/coinstring/) but it looks like it only validates simple BTC addresses (`1`-prepended addresses).

I'm looking for a JS library that can validate BIP16 [P2SH](https://en.bitcoin.it/wiki/Pay_to_script_hash) addresses.

You can use the library you've linked.

Instead of using:

```
isValid(address, 0)

```

use

```
isValid(address, 5)

```
