Multisig Wallet Concerns | Users Question Common xpubs in Coldcard Setup

A set of users are raising alarms about potential issues in multisig setups using Coldcard wallets, after noticing matching xpub digits across multiple devices. As they question the randomness of key generation, the community is divided on whether this indicates a vulnerability.

Context on Multisig Wallets

In a recent discussion, a user shared their experience setting up a 2 of 3 multisig configuration using three Coldcard wallets. They found that the first 10 to 13 digits of the xpubs were identical, which they deemed suspicious. This led to questions regarding the security and integrity of the devices used.

Concerns Raised

• Is this a security issue?

  Many users are stressing the importance of wallet integrity. One commenter voiced, "Would not be comfortable Is the device you’re using clean too?"

• Nature of xpub generation.

  Another user questioned, "Are the first 10-13 characters supposed to match for each xpub in a multisig setup?" This uncertainty has many considering their setup's correctness.

• Advice and exploration of issues.

  Users suggested seeking insight from tech-savvy sources, one saying, "I'd ask Grok; AI can provide deep info on BTC specifics, but always verify!"

Community Responses

Participants in the forums expressed a mixed sentiment. Some were alarmed, while others downplayed the concern, attributing the matches to protocol standards. "These first characters may just establish the protocol," stated one user, indicating that understanding these fundamentals might clear confusion.

Quote: "I'm not exactly groundbreaking, but keeping security tight is crucial."

Key Points to Consider

• 🔒 Identity in xpubs: Like fingerprints of wallets, the early characters might signify something essential.

• 🔍 Users confused about standards: The frequency of identical xpubs is raising eyebrows among many community members.

• 🔄 Verify configurations: As one user warned, a clean device setup is crucial for wallet security.

What's Next?

The ongoing discussion poses critical questions about security in crypto wallets. As users continue to voice their concerns, an increased focus on educating regarding wallet setups and maintaining device integrity may emerge.

Curiously, the crypto community's response to these security questions might influence future standards in wallet technology. For additional resources on managing multisig wallets, check Coinkite.
