Sorry if this is a dumb question, but how can I use the JSON-RPC to get a transaction's "return address"?  If I need to refund bitcoin, how can I get that address?

Many thanks!


Can't believe these goofy donation sigs really work.

There really isn't one. The only safe way is to get the sender to tell you where he wants the coins returned. There are many ways a person may send you coins from an address on which he cannot receive coins.

So how do all these ponzi games and lotteries work?  They send bitcoin back to the depositor.

There's no way to get that return address with the API?

I understand that refunds won't get back to the sender when sent from an online wallet, but when sent from the client isn't there a "from" address?

No, there isn't. Coins are never sent from an address, only to an address. Some of the coins in a transaction may have been claimed by particular addresses, but that is not a requirement, nor need a transaction have only one address used to claim the coins used in it. For example, I could mine a block and send your address the 50 coins I get for mining it. What's the "from" address in that case?
