Sweeping from a non-custodial wallet.

[RoyMillard]

I have a suspended account with bitbargain, and my bitcoins have been put into a non-custodial wallet.

I have to sweep the bitcoins from that non-custodial wallet into a new one I have created using Electrum. I have the key for the non-custodial account.

Can anyone tell me how to do this?

I'm not sure how Bitbargain works. Did they give you a bunch of phrases, a private key starting with 5, K or L or 6P?

Please do not share your private key with anyone on the forum, no matter how trusted they are. You should at most reveal only the first 2 characters of the key for others to determine what type of key it is.

They've provided me with a file containing three strings of characters (33 characters, 66 characters, 52 characters). One the three strings starts with a K.

I'm assuming the 52 characters line is the string that starts with K and that the 33 characters starts with 1?

Go to your Electrum wallet, at the top left, go to Wallet>Private Keys> Sweep and key in your private key in this manner.

Code:

p2pkh:K...

Afterwards, you should get a dialog that shows the transaction information, at the bottom left, there should be a slider that lets you adjust your fees. Depending on how long you want to wait, the current somewhat optimal is about 30satoshis/byte. Click Finalize, check again and then Sign and Broadcast.

Yes, that's correct.

I tried again, using just the string starting with a K, and that seemed to work. An amount has been transferred.

Any idea what the other two strings mean? It seems to have worked just using the third one.

The string starting with 1 is the address, the third being the private key. I have no idea what is the second unfortunately. The closest I can think of is an ECDSA private key which is only 64 characters. Nonetheless, you will be fine as long as you've swept the funds.

So sorry to ask, I generated addresses through derivation paths BIP32, BIP44, BIP49, BIP84 and BIP141 using BIP39 seed phrase with iamcoleman tool, all the private keys pair with addresses and their public keys all started from K and L. What is 5 and 6P starts for?

5 is the uncompressed WIF keys and 6P is the prefix for BIP38 encryption.

The other one with 66 characters is the public key, in compressed format. It should start with either '2' or '3'.
