Important security update for anyone using a COLDCARD. A serious vulnerability has been disclosed involving the randomness used by some COLDCARD devices when generating Bitcoin seeds. If you use one, move your bitcoin to a new seed generated elsewhere.

If you use a Coldcard hardware wallet, please pay attention. If you know someone who uses one, call them. Text them. This appears to be one of the most serious wallet security incidents Bitcoin has seen. If you're affected, don't wait. If you need help, reach out.

COLDCARD BTC MIGRATION VIDEO Here is an explainer video showing you how to do two things: 1. Set up a Casa multisig with your current Coldcard and send the assets from the Coldcard to the multisig. This eliminates the risk of loss from the CC vulnerability. Useful for people who only have a CC and don't want to send to an exchange or hot wallet. 2. Second part of the video (starting around minute 7) shows moving assets out of the Coldcard Mk3 single sig. This might be useful for anyone trying to move their assets right now that hasn't touched their CC in 4 years. Doing this was a fun reminder of how using a Coldcard outside of Casa is still surprisingly hard even though I know the gist of it and have been doing this for 8 years 😂. If you want help migrating to Casa, DM me or the Casa account and we will direct you to the team.

Nearly 600 bitcoin worth $38 million was drained through a Coldcard wallet vulnerability, New York sued Kalshi alleging it operates an unlicensed gambling platform, and JPMorgan says fading odds of the CLARITY Act are weighing on crypto markets. Jenn Sanasie has what you need to know. Thank you to JPEG Trading 👋 for being a sponsor of the CoinDesk Media Network.

The Bitcoin agent key can now live in a COLDCARD Mk4/Mk5 in HSM mode. Even if the host machine running your agent is fully compromised, the signing key stays isolated in hardware. The attacker gets nothing useful. Bitcoin agents with bounded authority. Now with HSM-grade key security.
