Re: Recover founds old multisig coinbase wallet

Hey OP, I've helped a couple of users in the past in the exact same situation as you. The issue is that the Coinbase recovery tool uses a now-defunct API, so it cannot access the balance on your addresses and then won't progress to letting you try to sign transactions.

There are a couple of options available to you. The most straight forward one is here: https://github.com/dlajarretie/multisig-tool
This is a direct fork of the Coinbase tool with the defunct API replaced with a working one.
Here's a user who successfully used this tool: https://bitcointalk.org/index.php?topic=5436171.msg61722006#msg61722006

If you are struggling to get this tool to run, then this thread might be of help to you: https://bitcointalk.org/index.php?topic=5444779.msg61907765#msg61907765

Thank you for your help!

I saw this message from you in the post you sent me,

Have you at least managed to identify the addresses and balances you are trying to gain access to here? You mentioned to me in your PMs that you are not sure how much bitcoin is stored in this vault.

Since we are struggling to get this to work for you, if you like you could send me your three xpubs (not private keys) and I could at least look up the addresses and balance for you. The only thing you lose by doing so is privacy by account of me knowing the addresses - there is no way for me to steal your coins from only knowing your xpubs. At least then we would know if you are wasting all this time trying to recover a very small amount of money. If you like I can provide you with my PGP key so you can encrypt any communication.

And moving forward, since we can't seem to get this tool working for you, then we could instead try going down the path of manually extracting the necessary xprv from your two keys and then recreating the multi-sig wallet in Electrum.

There are some posibilities about me for that? Im agree if a need to share with you my xpub, I have only this 10 euros, (now 800) in the bitcoin and Im not a advanced user only I would like to close this chapitre for me... because Im not relax, I have also the final adresse where there are the bitcoin

Thank you again!!!

Have a good day.
