Multisig Architecture Raises Eyebrows | Users Question Similar XPUBs

A recent discussion about multisig wallet setups has sparked concern among crypto enthusiasts. A user found that the first characters of three extended public keys (xpubs) from different Coldcard wallets were alarmingly similar, raising alarms about security among those setting up multisig configurations.
An Unexpected Finding
When helping a friend with a 2 of 3 multisig wallet using Coldcards, the user noticed that the first 10 to 13 digits of all three xpubs matched. This unusual occurrence led to questions about whether the keys are indeed as secure as they should be.
"Is my setup incorrect if the xpubs don't match?"
This quote captures the user’s concern about the integrity of their multisig arrangement. As it turns out, typical xpubs should be random, and identical segments could signal a risk.
Community Reactions
Responses from forums highlighted several key areas of concern:
Length of XPUBs: Standard xpubs usually exceed 100 characters long, which begs the question: Why are the first characters similar?
Understanding Format: One user mentioned, "These first characters may just establish the protocol," suggesting there might be an innocuous explanation.
Trust in Devices: Another comment stressed, "Would not be comfortable Is the device you’re using clean too?" indicating skepticism around whether the technology is secure.
