I have used a few different scripts.
Microwallet in my opinion has the best/modern one, if you do not play with the layout too much, the ad placement is good for converting into clicks.
https://www.microwallet.org/apiDoes the Microwallet faucet allow for multiple coin types? For example, if I wanted to setup a DogeCoin faucet at doge.mysite.com and a MintCoin faucet at mint.mysite.com, could I do it (with two separate databases and installations, of course)?
Also, can users use their own wallet addresses?
