I am sharing here a message I shared with the StarkWare team following things I said at an All Hands meeting: ======== StarkWare is adapting its strategy, with a clear goal – to lead blockchain. So far, we’ve secured our position as technology leaders: we built the best ZK proving blockchain technology. Cairo, Sierra, Post-Quantum, etc. More than anyone in the industry, StarkWare demonstrated the potential of ZK and STARK technology and has set the standard. Each and every StarkWare employee should be extremely proud. Why do we need a new strategy? We initially focused on scaling L1s, building the most advanced scaling stack. But infrastructure alone does not win the game, and although different apps demonstrate where our technology shines, we are not playing our full hand. We can do better. It is now time to convert our technological superiority into tangible revenue and significant usage, with high emphasis on products that can be powered only by our technological moat. To execute this, we must change how StarkWare operates. New focus: We're shifting from doing many things well to doing fewer things excellently. Emphasis is on things with large potential value that only we can build, that only our stack, the best in the world, can unleash and make come true. We’re adopting a new mindset: Moving fast, in small teams, doing a lot of experimentation, and being confident to rapidly iterate to find PMF. This is a mindset that differs from the way we currently operate, and it’s one that will be rewarding. It’s a bit like going back to startup mode, but taking into account all that we’ve learned from building the best infrastructure in the world. Big picture: There’s a vacuum in blockchain leadership today – this poses a challenge but also an immense opportunity for StarkWare and Starknet. We’re playing to win. More details next week. New structure: - 2 purpose-focused units, one led by Avihu and one led by Tom as general managers (GM) - Each of these two units will manage internally its dedicated BD/eng/product/GTM. Very sadly, as part of this process, we are downsizing. Our new strategy requires that we move fast, and we’re too big and too inefficient for that. So, we are making a tough but responsible decision to become smaller and more flexible. This is painful because we are parting from excellent people. I deeply appreciate each and everyone of you. We will do our best to soften this parting, in many jurisdictions going beyond what law and contract dictate. Those we’re considering parting from, will shortly receive an email invitation for a 1-1 meeting with management. I know this is difficult news, and I wish we could have avoided it but our commitment to our mission dictates that we make it. For those staying, we recognize this is a dramatic change and we’ll talk to each of you as well, but will do so after talking to those affected most by this change. To all, we are available to discuss whatever is on your mind, during the hearings and outside of them. I myself am available over the next days for each and every one of you, simply step in, write, or call me. I want to hear you if you want to be heard. Summary: We built the best, safest, most battle-tested ZK tech in blockchain. We’ve redefined blockchain using our technology, but that’s not enough. I’m anticipating with confidence our next chapter, in which we use it to advance exciting novel products that generate revenue and which cannot be built on other blockchains today. It’s a huge challenge, that requires a large and painful change, and will require immense effort. I’m confident that our reorganized structure, focus and strategy, position us well to go after this ambitious goal, winning and leading blockchain. Let’s get to it.

Looks like we are seeing another mass address poisoning attack on Ethereum Mainnet. Yesterday, there were 2.8 million native ETH transfers, a 100% increase from the baseline. Be sure to double-check which wallet you are sending to. Hackers are creating very similar-looking addresses and sending tiny amounts of ETH to trick people.

Does anyone still believe @justinsuntron ? Justin’s favorite move is playing the victim while making baseless allegations to cover up his own misconduct. Same playbook, different target. WLFI isn't the first. We have the contracts. We have the evidence. We have the truth. See you in court pal.

Kraken Security Update We are currently being extorted by a criminal group threatening to release videos of our internal systems with client data shown if we do not comply with their demands. It’s important to start with the most important points: our systems were never breached; funds were never at risk; we will not pay these criminals; we will not ever negotiate with bad actors. Kraken identified and shut down two instances of inappropriate access to limited client support data. In February 2025, we received a tip from a trusted source regarding a video shared on a criminal forum that appeared to show access to our client support systems. We immediately launched an investigation and quickly identified the individual involved as a member of our support team. Their access was revoked immediately, a full investigation was conducted, additional security controls were put in place and a limited number of affected clients were notified. Since then, we have been collaborating with industry partners and law enforcement to investigate and disrupt insider recruitment efforts targeting not only crypto companies, but also gaming and telecommunications organizations. More recently, we received another tip, along with a new video showing similar activity. We quickly identified the individual involved and terminated their access. As before, we acted immediately to revoke access, conduct a full investigation, and notify the small number of affected clients. Across both incidents, only a very small number of client accounts were potentially viewed - approximately 2,000 in total (0.02% of clients). Shortly after access was terminated, we began receiving extortion demands. The criminals threatened to distribute materials from both the February 2025 incident and the recent incident to media outlets and on social media if we did not comply. We will not pay these criminals. Based on intelligence gathered across both incidents, along with extensive ongoing analysis, we believe there is sufficient evidence to support the identification and arrest of those responsible. We are actively working with federal law enforcement across multiple jurisdictions to pursue all individuals involved and bring them to justice. Due to the ongoing investigation, we cannot share additional details at this time. However, anyone with relevant information is encouraged to contact us directly. The security of our clients is our highest priority, and we remain fully committed to combating the growing global threat of insider recruitment and constantly enhancing our security practices to combat new threats. Note: If you are a client potentially affected by this, you've already been notified.
