Hello !
I made a transaction using Cryptopay as gateway.

https://blockexplorer.com/tx/6ef93907a5c1eb91f5dad8b2474478203671f57b5de110a6bb6d8d036dcd5db7

Payment went in timeout and they asked me a refund address ... so i gave this one : 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL
Electrum indicate this as "sender eddress" with 0.01285825 btc moved.


Actually I've not received any refund.
Maybe I gave wrong address ?
How can i check if a refund was really sent ?


Thanks.

The 0.01285823 BTC in the transaction you linked above is probably your change. You sent 0.00089277 BTC to Cryptopay (address 16VJXy...) and the change of the transaction was sent back to your 3PFoh... address. If you didn't receive your refund, they probably didn't send it yet. Wait for it, and if nothing comes in after a day or two, contact them.

If your wallet is acting weird for whatever reason; you can check the block explorer:

https://blockchair.com/bitcoin/address/3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL

Indicates that you have received 3 transactions on this adress, of which 3 (all of them) are unspent.

Meaning that if you control the private key to 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL, you should be able to access your funds just fine.
Of course i don't know whether or not those 3 transactions included the refund of cryptopay, you'll have to figure that out yourself.

(Is 6ef93907a5c1eb91f5dad8b2474478203671f57b5de110a6bb6d8d036dcd5db7 the original tx or the refund tx?)


It looks like this is what happend?: Your funds went from
3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL (https://blockchair.com/bitcoin/address/3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL)
to 16VJXyHdn32HpY4viLCes31kjuhPXoDdJN (https://blockchair.com/bitcoin/address/16VJXyHdn32HpY4viLCes31kjuhPXoDdJN)
to 1ErwCCZ1kXErcJP2vf7o5Hpm4cUonx1Z7e (https://blockchair.com/bitcoin/address/1ErwCCZ1kXErcJP2vf7o5Hpm4cUonx1Z7e)
to 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL (https://blockchair.com/bitcoin/address/3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL)

???

That address has received:
+ 0.01285825 on 2019-12-02 21:19:34

Are you referring to another transaction or is this the one?

Does your electrum show a balance in the bottom left corner or does it say "not connected" or "synchronising".
Is this a hardware wallet or did you import a seed? Electrum doesn't have 3-type addresses as standard.

I'm not sure that's correct, TryNinja.

The transaction 6ef93907a5c1eb91f5dad8b2474478203671f57b5de110a6bb6d8d036dcd5db7 is from a legacy address to a legacy and nested SegWit address. Isn't it more likely therefore that the legacy address is the change and the nested SegWit address is the recipient?

The 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL address has received three transactions including the transaction above and has a balance of 0.02573316 BTC. If you can't see any coins, are you sure that address is part of your wallet?

You may be right.

I didn't notice the sender address was a legacy one. But he said he gave the 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL address so Cryptopay could refund him, and that's the address receiving 0.02573316 BTC, so that can't be the receiver address (Cryptopay). That is, assuming the transaction above is his payment attempt, rather than the refund. But if it really is the refund, that explains all and his refunded coins are at his 3PFoh... address.

OP, please specify. What was your payment attempt transaction? And from which address and to which address you sent them from/to?

I wonder if they have asked for a refund address and he has accidentally sent them their own address?

I believe this is exactly the case here.
Cryptopay refunded (https://m.btc.com/0e9bf962c4ea4c68feab9636095eefbf1820ce3676c1e5e6fb4e7adcf5c56cb5) him but the coins were sent to their own address (which he provided).
@op, you have to contact Cryptopay's customer support  and explain what happened. When they ask you for a refund address, again, click the receive button on Electrum and copy the address your wallet provides.

I made a mistake, you are right.

I gave to Cryptopay their own address.
Mine is 1DgCqmHHwPHikNApRtqhnic9FyoQWjeY1N ... is this correct ?

Yes, those yellow highlighted addresses are yours; specifically, your change address.
Additionally, if you found green highlighted address, that's one of your receiving address.

The simplest thing to do is to open Electrum, click on the receive tab and copy the address displayed there and give that to CryptoPay. That will guarantee that you are using a receiving address from your own wallet.

The addresses highlighted in YELLOW by Electrum are "change" addresses... they are not "receive" addresses. You should not deliberately attempt to receive a payment to them from an external party for reasons that are outside the scope of this discussion. Note that it will work... and you'll be able to receive the payment... but it is not advised.

So, how I know the SENDING address for this transaction ?

Thank you ( all ) for support  ;D

If I understood correctly you are supposed to receive a refund from them so you need to send them one of your RECEIVING addresses. One that is part of YOUR wallet and whose private keys are in your possession. Do what HCP told you and go to the receive tab in your client and copy an address from there.

In the picture you have linked to above:

1DgCq... is your address that you are sending coins from
16VJX... is your change address that the left over coins are returning to
3PFoh... is Cryptopay's address that you are sending coins to

To obtain your refund, either just ask them to return the coins to the same address (1DgCq...), or preferably do as HCP has said above and click on the "Receive" tab.

From the transaction window (your screenshot):
The "sending address(es)" are the ones in the 'Input(n)' box.
The "receiving address(es)" and your change address are the ones in the 'Output(n)' or 'Uscite(n)' box.

The problem is: Looks like they've already sent address 3PFoh63XFv4HPGKzD5SJsdtjCSZ6hhq7kL the refund (Your Transaction (https://www.blockchain.com/btc/tx/6ef93907a5c1eb91f5dad8b2474478203671f57b5de110a6bb6d8d036dcd5db7) | Refund Transaction (https://www.blockchain.com/btc/tx/0e9bf962c4ea4c68feab9636095eefbf1820ce3676c1e5e6fb4e7adcf5c56cb5))
