This is a big one.

I've known Jessy for as long as I've worked in Bitcoin. He's an incredible friend and father, and easily one of the sharpest advisors in the industry. The guy is genuinely motivated by serving his clients and their families, and building what he believes should exist in the world.

I can also personally vouch for his ability to construct a custom duct and noise suppression system so he could heat his entire house with a single Whatsminer M30S+. Who wouldn't want that from their advisor?!

Really proud to see the launch of Verify Wealth. Congrats @idahohodl. Looking forward to pointing Legacy OpSec clients your way.

I spent the last 4 years learning about what bitcoin holders actually need from a financial planner, and what the traditional financial planning industry keeps getting wrong about them.

Today, I'm launching Verify Wealth (@vrfywealth) built for that client specifically.

Flat fee planning, so compensation does not scale with your bitcoin. Encrypted communications by default. No client information touching Big Tech AI. Planning, tax, inheritance, and custody, all coordinated under one roof.

Strategy. Simplicity. Security.

If you've outgrown your advisor, let's have a conversation this week.

Make the move to multisig with hardware wallets from different vendors.

The current situation is bigger than Coldcard.

Bitcoin custody should not depend on one seed, one device, or one manufacturer.

Multi-vendor multisig, collaborative custody, and multi-institution custody are designed to reduce the impact of any single device, firmware, or vendor failure.

Here’s an early preview from the upcoming Legacy OpSec Bitcoin Hardware Wallet Buyer’s Guide, showing how leading signing devices integrate with popular wallet coordinators and collaborative custody platforms.

Coldcard remains in the matrices for an accurate view of platform compatibility. However, Legacy OpSec recommends migrating away from Coldcard to another hardware wallet or custody platform while Coinkite's investigation remains ongoing.

For those who prefer not to manage their own keys, Onramp Multi-Institution Custody is another option worth evaluating.

If you want help comparing these models, choosing compatible devices, or implementing a more resilient setup, DM me or reach out to @legacyopsec.

For a limited time, we're waiving the $450 onboarding fee for new ongoing clients.

Update after 22 hours:

We’re still providing around-the-clock transaction assistance for anyone affected by the Coldcard vulnerability.

So far, Legacy OpSec has helped move more than $1M in bitcoin to wallets secured by new seeds, with no reported losses among the clients we’ve assisted.

If you need hands-on help reviewing your setup or migrating funds safely, reach out.

This is a difficult moment for many Bitcoiners, but it will pass. Stay calm, verify every step, and don’t rush a transaction you don’t understand.

DM me, reply here, or reach out to @legacyopsec.

We’ll be up late tonight at @legacyopsec helping anyone who needs to move bitcoin secured by a Coldcard MK3 to a new wallet.

If your MK3 is part of a multisig setup or used with a collaborative custodian like Unchained or Casa, the reported vulnerability does not appear to put your funds at risk. The primary concern is single-key setups.

If you’re unsure how your wallet is configured or have questions, reach out. DM me, reply here, or call me directly if you have my number.

BTC Sessions is live right now walking through how to migrate funds from a Coldcard wallet using Sparrow.

Ben is one of the best Bitcoin educators in the space and an excellent resource. Follow along with his walkthrough, or reach out to me or @legacyopsec if you need hands-on help moving funds to a wallet secured by a new seed today.
