Send many small payments

[giantdragon]

Is it possible to send many small payments simultaneously and pay smaller transaction fee?

Yes, the bitcoin protocol allows this but you'd have to craft the transaction yourself since the bitcoin client doesn't allow you to sent payments to multiple addresses in one transaction. As long as the sum of the inputs is less than the sum of the outputs then the transaction is valid.

I want to do this from my PHP website. Does BitCoin API allows it? Does external libs exists to do that?

There was a website that offered something like this and I think a script too, not sure if it was in PHP. I'll look for it.

Isn't this just the sendmany function? ./bitcoind --help and read up on it. No special crafting needed, format already exists to do this.

I wasn't aware the sendmany command had been pulled into main - that's pretty cool.  Someone needs to update the api call list?
