8 Years, One Big Leap 🚀 Eight years ago, I was a student with a passion for cybersecurity, great curiosity, and a desire to build something meaningful. Today I’m stepping into the role of CEO, and this moment means everything. We launched @hackenclub from pure passion and a big vision to make the digital world safer. At the darkest times, we joke that the “all guts, no brains” motto helps us to fail and start again. What began as a bold idea grew into a global cybersecurity company protecting the foundations of Web3 and beyond. Since then, I’ve done it all: from jumping on client calls at 2 a.m., gathering the first ethical hackers for our bug bounty platform, building teams, launching products, handling crises, traveling the world… and learning. Always learning. To my cofounder @buda_kyiv, who is now Chairman of the HAI Group, thank you. Your belief, partnership, and integrity shaped the foundation of this company. I wouldn't be here without you and your trust in me from the very first day. From a student with big dreams, to now leading one of the most respected cybersecurity companies in Web3 — I’m proud, grateful, and more driven than ever. Together, we turned Hacken into a provider that delivers enterprise-level security for the entire decentralized stack and meets modern regulatory requirements. Thanks to our deep Web3 expertise, we understand what the landscape needs right now, and lead it steadily towards a safer future. As CEO, aim to push these boundaries even further, championing innovation while never losing sight of what matters most: trust, resilience, and proactive defense. My focus moving forward will be on doubling down on the U.S. market and the institutional players leveraging digital assets. Our mission is clear: to help them build secure systems with our deep expertise, holistic services, and a defence-in-depth approach tailored for modern threats. I’m incredibly proud of what we’ve built. I’m even more curious and energized about what’s ahead!

Starting today, @buda_kyiv steps up to lead HAI Group – a new corporate structure in crypto. His visionary thinking and creative leadership are set to unlock new horizons in Web3 security! Thank you for believing in me from the very first day. If the last eight years are any indication, we’re in for something amazing ✨
Dear Hacken Community, Partners and Friends, Today marks eight years since Hacken was founded, and I could not be more proud of what we have built together. We are no longer a startup. Hacken is now a global brand, trusted by the world’s leading blockchain projects, regulators, and enterprises. 1️⃣ A New Era for Hacken For eight years, we have evolved alongside this industry. We have exposed bad actors, set standards, and proven that vision backed by action can change the world. Now it’s time to set bigger goals, with the right people fully accountable for achieving them. Every change we are making today is about clarity, accountability, and scale. 🔹 Hacken: new global and regional leadership to accelerate expansion. 🔹 HackenProof: true independence with legal ownership for its team. 🔹 Hacken Federation Network: the first legal innovation of decentralized cybersecurity companies. 🔹 HAI Group: a fully new structure – a financial instrument that represents the entire Hacken ecosystem and returns value to HAI holders. 2️⃣ Hacken Federation Network To accelerate Hacken’s global expansion, we are making one of the most significant structural changes in our history: Yevheniia Broshevan, Hacken Co-Founder and Chief Business Development Officer, is stepping into the role of CEO of Hacken. If you’ve worked with Hacken, you already know @jerh17. She is the reason we secured many of our biggest clients. She has been at the heart of our growth since the very first brainstorm in 2017. Beyond that, Yev is a cybersecurity expert with 12 years of experience, including a deep and growing interest in AI security. She has the trust of the team, the respect of our partners, and a clear and steady vision for what Hacken should be. I cannot imagine a better person to lead this company forward. 3️⃣ My New Role: Building HAI Group We are creating a completely new corporate structure – the first of its kind in crypto. It will be called HAI Group, structured as a Crypto IPO-ready holding company. HAI Group will own part of Hacken Services and all of our industry-grade products. Design for scale, fundraising and IPO 🔹 We will tokenize the holding company itself – a model never done before in crypto. 🔹 This security token will give HAI holders direct access to the growth and success of the entire Hacken ecosystem, uniting all B2B and B2C utilities in one instrument. 🔹 We will spin out major products as independent legal entities, giving their teams ownership stakes and the ability to raise capital directly. 🔹 HAI Group will remain the major shareholder, aligning everyone behind the same long-term vision. What This Means ▫️ Hacken will be laser-focused on scaling as a global cybersecurity leader, led by Yev and regional CEOs. ▫️ We will build a Hacken Federation Network of independent partner-led firms in North America, MENA, Europe, and beyond. Think Deloitte’s global scaling model, but with HAI as the security token at its core. ▫️ @HackenProof will become an independent entity, unlocking its full fundraising potential and innovation capacity. ▫️ HAI Group will hold part of Hacken and all of our products, giving B2B and B2C stakeholders access to its success through a security token. 4️⃣ My Focus As a co-founder and major shareholder, I take the non-executive role of Hacken Chairman as well as CEO of HAI Group. My goal is to build a network of independent entities under HAI Group, designed for tokenization, fundraising, and going public. I will also play a big role in a new product we’ve envisioned for years but never had the space to fully bring to life. It will stand at the intersection of DeFi, insurance, fintech, and AI, built on the foundation of CER.live, TrustArmy, and hAI app. This will be a product the entire industry will come to rely on. I will share more in due time. But know this: it is going to change how security, risk, and trust operate in Web3. Thank you to everyone who has supported Hacken on this journey – our clients, partners, community, and the thousands of HAI holders who believed in our vision from day one. The next era starts now Dyma Budorin Hacken Co-founder and Chairman, $HAI Group CEO

I recovered 80% of my funds from #FTX after failure in 2022. That was surprisingly easy with @ftxcreditor_com . You just need submit your data, get a quote, have KYC done, schedule a call, transfer account and get your money back in USDC. Unfortunately you get it by BTC/ETH rates from 2022. But it’s way more than 0 :) Sell your claim: ftxcreditor.com/sell_claim?a…
