Strike is proud to stand with @bitcoinpolicy and this coalition. Attackers already use AI without limits. The people defending against them shouldn't be the ones held back. Give defenders access to the best tools, and frontier AI becomes one of the strongest defenses we have. It's time to give defenders the tools they deserve.

AI has changed the economics of Bitcoin security. The cost of finding vulnerabilities has collapsed. Coldcard. BTCPay Server. The Bitcoin Red Team. Open source software. AI agents. What "secure" means now. New Mailbag Monday LIVE with @jackmallers at 6pm ET

Yesterday I began fully integrating the @OpenAI trust cyber program into my Bitcoin Red Team efforts. This morning I woke up to see this. I am now being blocked from doing additional analysis on a codebase which I've already responsibly disclosed to, and have received confirmation had legitimate findings. To be clear, this is after having already KYC'd and completed the onboarding process months ago to use the cyber capabilities OpenAI has to offer. I am now prevented from being able to continue the investigation in a further effort to make sure their code changes are sufficient, as well as understand if there are other issues that have yet to be discovered. It absolutely guts me as a patriotic American to have to do this, but I will be going back to using Chinese open source models to conduct my research to protect Bitcoin infrastructure. Black hats will not hit these issues. The white hats will. We've hit a local minima in policy. Intelligence is unrestricted for those who don't follow rules, and those who engadge in harm reduction are left on the sidelines. What are we doing in this country? How is this keeping people safe? Please do something @DavidSacks @sama @realDonaldTrump

There is a critical vulnerability being actively exploited on BTCPay Server, which can result in the loss of funds. Please update your BTCPayServer to 2.4.2 by going to Admin Dashboard -> Server -> Maintenance -> Update & verify the 2.4.2 version string in the footer. If you are unable to update right away, turn off your BTCPay Server to prevent unauthorized access until you can update.

Every week we ship new features to make Strike the best place to bank on bitcoin. Last week we shipped three things: beneficiary planning, account switching, and a profile card that's uniquely yours. Here's a closer look 🧵

This week’s episode is not about markets or macro. Today Jack breaks down private keys, randomness, the Coldcard incident, seed migration, multisig, and what Bitcoin custody actually means for Main Street. Back to first principles. LIVE with @jackmallers today at 6pm ET 👇

Keeping your bitcoin safe is the most important thing we do. Strike comes with a wide set of security features designed to protect your account. Here's how each one works 🧵

Check in on your fellow Bitcoiners. If you know someone using a potentially affected Coldcard, make sure they're aware of the recent security incident. We've seen a meaningful increase in bitcoin deposits to Strike as customers review their custody setup. Strike is not affected by this incident. If you're reviewing your own setup, our team is here to help. Strike supports free bitcoin deposits, unlimited free bitcoin withdrawals, and security features like PIN, 2FA, and more, so you can move and store your bitcoin whenever you choose.

To every @Strike customer, thank you for your continued support. We work for you. I know some Bitcoiners hesitated to join Strike because they were worried about a potential relationship with Twenty One. I understood that, and honestly, it always hurt to see. Strike will remain independent, private, under my control, and fully focused on serving Bitcoiners. If that concern kept you from trying Strike, DM me. I’d love the opportunity to earn your business. I’m biased, but I believe we offer the best Bitcoin experience in the world. I’m incredibly fired up to keep building for you all. A lot more is coming soon! 🫡

I've decided to step down as CEO of Twenty One. This wasn't an easy decision, but it was the right one. This experience brought tremendous clarity about who I am and what I want to build. My life's work remains Bitcoin. My Bitcoin company is @Strike. The work continues.

Satoshi solved digital scarcity. Bitcoin solved money. When someone tells you they need another token, a money where they're the central bank, ask: Why? If your product is valuable, why does it need its own money? No man should work for what another man can print.

Trump says he's taking over the Strait of Hormuz, China's AI is getting cheaper and gaining ground, Big Tech suddenly flipped on the AI jobs wipeout, all as yields soar. Where does that leave the orange coin? New episode of Mailbag Monday with @jackmallers is live at 6pm ET 👇

Don't let anyone convince you that Bitcoin belongs to Wall Street or big corporations. Its strength comes from the millions of people around the world who wake up every day and earn, save, stack, and hold. You matter. Bitcoin has always been a grassroots monetary revolution.

Every corner of the economy is quietly moving onto the money of the internet. New businesses on Strike this week: - Catholic Bitcoin donation platform - Investment firm - Moving company - Power washing crew - Jewelry store - Yoga non-profit All choosing to save in bitcoin.

Introducing volatility-proof loans. Borrow against your bitcoin, and the price no longer has a say in what happens to your collateral. No margin calls. No price liquidations. Bitcoin falls 80%? Your stack stays yours. Make your payments. Keep your bitcoin. Ignore the price.

The Fed Bluff, The AI Bubble & The Bitcoin Bottom According to math, the Fed being hawkish is noise. Meanwhile, is the AI bubble showing signs of slowing down? All this while Bitcoin seems to be working on forming its bottom. New Mailbag Monday with @JackMallers LIVE at 6pm ET
