Need help retrieving bitcoin after a cancelled transaction

[WoodyHaze]

I cancelled a multisig transaction. I am just learning about such transactions, and as it turns out the btc was refunded to a wallet that i had not used previously. I don't remember the login info, but wonder if I know the address and have the keys associated with it, is there anyway to get to the wallet?

How did you cancel the transaction? Generally, once a transaction is broadcast to the network it can't be cancelled.

The BTC will not have been refunded to a wallet, it will have been refunded to an address. If the receiving party refunded to an address OTHER than the sending address, then they are at fault. You should never refund to anywhere other than the address that sent the funds or you run the risk of sending BTC to the wrong person.

In any case, if you know the address the funds were returned to, and you have the private key(s) for it... you should be able to create a transaction that sends the coins to wherever you like.

i see...that does sound promising. I know the btc went to that address, and i have the private key, so it does make sense i could do just what you said. ok...let me work on that. i am certainly novice to this. thanks for responding quickly and kindly.

As you suggested I created a transaction and was able to verify and sign, however when I attempted to broadcast, I guess I am having trouble understanding how to come up with the "valid signed transaction hexadecimal string." It seemed as if I had come to the final step, however I am going to have to dig a bit deeper to understand this. You have put me on the right track, no doubt

What wallet are did you use to send the MultiSig transaction from initially? and what type of address did the BTC get returned to? Does it start with a "1" or a "3"?

[WoodyHaze]

The MultiSig transaction was initiated on a marketplace, from my funds in the account there. Upon initiating the transaction , the funds are sent to an escrow wallet. I cancelled transaction when it was in escrow stage. The refund address is one that I cannot remember the login info, but it starts with a 1, was created via coinb.in, and I have the keys. And it shows inputs equal to the refund. I know it's a bit confusing, and I've learned a lesson, but at same time it seems I'm very close to creating a transaction like you suggested.

[HCP]

If it has been sent back to a "1" address... which you have the keys for... you could either import the private key into a wallet like Electrum which would allow you to create a transaction and send all the coins to wherever you want... Or you could do it all manually using: https://coinb.in/#newTransaction (download the offline copy as per the links at the bottom of that page)

Just put in the public address at the top, click "Load"... it'll load all the unspent inputs. Adjust the options as required (I'd recommend enabling RBF in case you miscalculate the fee). You can then input the output address and amount you want to send... (NOTE that you need to calculate the fee manually. Current recommended fees are totally retarded at 450 sats/byte!!?! )

Click submit, get the unsigned Transaction Hex...

Use the "Verify" page (https://coinb.in/#verify) to double check everything is how you want it...

If it's all ok, then goto the "Sign" page (https://coinb.in/#sign) paste in the hex, put in the private key... and get the signed Transaction Hex...

Then use the "Broadcast" page (https://coinb.in/#broadcast) to actually send your transaction

[WoodyHaze]

Ok...that's what I have been attempting. On coinb.in. Only thing is, I wasn't aware of having to calculate the fee manually. I am about to try it again. Fortunately, it does show unspent inputs basically equal to the refund amount, so the funds were indeed returned.

I can't thank you enough for your help and patience. I will let you know upon making a successful Transaction

[WoodyHaze]

Well, this time when at the broadcast stage of putting together this transaction, rather than the message saying "no valid signed transaction hexadecimal string," i received instead a Txid! After I made the transaction an RBF it did broadcast. That was just now, and I am going to sleep now, hopefully to find the coin available when the morning comes.  Thank you SO much for walking me through

[HCP]

good to hear you got it sorted. It's s useful set of tools, but they don't really explain some of the stuff, like needing to ensure you have actually left some coin for the transaction fee!

[WoodyHaze]

well, the transaction id doesn't seem to be noticed by blockchain info, so i am wondering if its just a matter of time after broadcasting, or if i have yet to get it quite right. neither of the addresses involved show the transaction either.

[HCP]

Sounds like it didn't propagate well.  You can try broadcasting using:
https://blockchain.info/pushtx
http://blockr.io/tx/push
https://pool.viabtc.com/tools/BTC/broadcast/
https://live.blockcypher.com/btc/pushtx/

and see if they give any errors...
