Can you Send Coins back from a Receive Address?


We are setting up some merchant functions

If a customer sends too many coins in a transfer for an order

Can you send the change back to address you received the coins from .

i.e 1) Order 1234 12.5 BTC Merchant Recieve Address (1234abc)

2) Customer Sends 12.6 BTC to Merchant Address (1234abc) from his Address (4567def)

3) Merchant detects overpayment And sends the 0.1 btc back to customers (4567def) Address as change

Will this work in that the customer will get his change ??

Did you mean "back to customer's (4567def) address"? – Meni Rosenfeld – 2013-02-16T21:04:33.950

Yes back to the customers 4567def address – BitCoin New Guy – 2013-02-16T21:07:42.717



This is not recommended.

If the customer uses a fully controlled wallet he will get the coins, but will be confused about their source because the address would carry the label of some other provider.

If the customer is using a shared eWallet, he might not get the coins at all because the address isn't his.

On the shared wallet is it likely that the app is using an address not related to the user etc ? – BitCoin New Guy – 2013-02-16T21:05:22.703

1How would you deal with this situation ??? Prompt the user for a change address ?? – BitCoin New Guy – 2013-02-16T21:06:18.820

1@BitCoinNewGuy Indeed - If you need to do a refund, ask for a refund address. – Pieter Wuille – 2013-02-16T22:04:45.820
