user131236: I come to you a little bit desperate, hoping for a clue to move forward.
Long ago, I created 3 seed phrases, and then made a 2 of 3 multisig wallet with these 3. I did all of this using Cold Cards
For each, I engraved metal plates with the seed phrase, derivation path, fingerprint and zpub.
I tested each of the 3 and restored them to validate I had enough information to access my funds from each individual wallet.
In addition, I used the 3 plates to restore the entire multisig wallet and validated I could access my funds from the multisig wallet too.
I stored each of the three plates in a different location, as conventional wisdom dictates. This means that I can secure the other two in the event that any one is compromised.
Unfortunately the worst has happened and one of my sites was ransacked during a time period in which I could not access it due to travel restrictions. This is a hard lesson learned. Fortunately (I thought) I still have access to the other 2 seed phrases and respective details.
So I immediately retrieved the other 2 seed phrases and began to attempt to restore them.
As I previously validated, I can access each of the 2 wallets using their seed phrases. However, I cannot access the majority of my funds as during the software wallet setup stage (Sparrow wallet, but I have since tried countless others) it asks me for the zpub of all 3 seed phrases to generate the watch only multisig wallet.
As such here I am, with 2 of my 3 seed phrases, unable to access my funds.
Is all hope lost? Can anyone help me access my funds?
Cheers

user5406: Unfortunately, you need two private keys to spend but all three public keys to recreate the redeemscripts of the addresses. Unless you have a way to find out the third public key, you will not be able to spend.

user131958: I think hope is lost, but let's give it a try...
You mentioned, you created all of this using coldcards. As coldcard is a stateful wallet, meaning each device itself needs the full multisig-wallet information (derivations, fingerprints, xpubs) for it to sign a multisig-transaction, maybe the full public key information is still saved on one of the coldcards?
How did you coordinate the multisig-wallet in the first place?
If you, at the time, followed coldcards tutorial there should've been a step where you handed the multisig-wallet information to each of the devices (by passing the SD card around). This is also true for software wallets (although not every software wallet has a prompt to do that...).
