About this event
DeFi security looks very different than it did five years ago. The biggest risks are no longer just simple smart contract bugs in isolated protocols. Attack patterns have evolved alongside protocol design, liquidity structures, cross-chain systems, governance mechanics, and increasingly complex integrations. If you work on or around DeFi, understanding how these hacks have changed is no longer optional background knowledge; it is a core part of building, operating, and evaluating protocols responsibly. This in-person session is built for people who want a clearer view of that shift. Rather than treating exploits as a list of headlines, the event will focus on how attack surfaces have expanded, what lessons have actually held up over time, and what protocol teams need to do differently now. Expect a grounded conversation about patterns, blind spots, and practical implications for builders, researchers, and serious DeFi participants. About the Event This event explores how DeFi exploits have changed over the last five years and what those changes mean for modern protocols. The goal is not just to revisit well-known incidents, but to understand the broader evolution of risk across the ecosystem. As DeFi has matured, protocol architectures have become more composable, more interconnected, and in many cases more fragile in unexpected ways. The conversation will likely be most useful for people who want to move beyond surface-level security talk. Instead of reducing hacks to isolated mistakes, the event centers on how incentive design, governance structures, oracle dependencies, bridge assumptions, liquidity dynamics, and operational processes can all contribute to failures. Because this is an in-person gathering, attendees can expect a more direct and engaged experience than a passive livestream or online panel. The format is well suited to sharp discussion, follow-up questions, and the kind of nuanced back-and-forth that security topics usually require. This is also a strong fit for people who value community context. DeFi security is not just a technical problem; it is a coordination problem across builders, users, risk teams, and researchers. Bringing people into the same room creates space for more candid, practical exchange. What to Expect The event will center on the changing nature of DeFi exploits over time and the practical lessons protocols should take from that history. Rather than focusing only on code-level vulnerabilities, the discussion will likely touch on how entire protocol systems can be stressed or manipulated. You can expect themes such as: How exploit patterns have shifted from simpler smart contract issues toward more layered attacks involving multiple dependencies or market conditions How composability has changed risk, especially when protocols rely on external primitives they do not fully control Why operational and governance weaknesses matter, even when core contract logic appears sound What protocol teams should reassess today, from architecture and assumptions to monitoring, response planning, and risk communication Attendees should also expect a balance between retrospective and forward-looking analysis. Looking back at the last five years matters because it reveals which assumptions proved dangerous, which mitigations worked, and which security habits no longer match the current threat landscape. There will also be value in the room itself. Given the community and networking focus, this is a good setting to compare perspectives with others working on similar questions: what counts as acceptable protocol risk, how teams prioritize security tradeoffs, and where the ecosystem still tends to underestimate exposure. Why Attend If you are building in DeFi, this topic directly affects product design, user trust, and protocol resilience. Security is often discussed as a specialized function handled by auditors or researchers, but the reality is broader: protocol risk is shaped by design decisions made long before deployment and by operational choices made long after launch. This event helps sharpen your ability to spot those design-level and system-level risks earlier. By understanding how exploit strategies have changed, you can better evaluate whether current assumptions inside a protocol are actually robust or just familiar. Attending can also help you ask better questions. That matters whether you are reviewing a protocol, allocating capital, contributing research, or helping run a community around a DeFi product. Better questions lead to better threat models, better internal conversations, and often better decisions. You should leave with: A clearer mental model of how DeFi attack surfaces have evolved A stronger sense of what modern protocols need to defend against Practical insight into where old security thinking may no longer be sufficient Useful peer context from others who care about protocol design, risk, and ecosystem resilience Practical Details This is an in-person event taking place on Thursday, February 12 at 10:00 AM EST. If you prefer learning through real conversation rather than scrolling post-mortems alone, this format should be a good match. Because the topic is specialized but broadly relevant, it helps to come prepared with your own lens. Whether you approach DeFi from engineering, research, investing, governance, or active participation, you will get more from the session if you are ready to connect the discussion back to real protocol decisions and tradeoffs. A few good ways to prepare: Bring examples of security trends or protocol design shifts you have noticed Think about which assumptions in DeFi feel most fragile to you today Be ready to discuss not only technical exploits, but also governance, liquidity, and operational failure points If you care about how DeFi risk has actually evolved, and what protocol teams need to do differently because of it, this event offers a focused place to dig into that question with others who take it seriously.
Who should attend
This is for you if you want a more serious, current understanding of DeFi risk than the usual high-level security commentary. - You **build or contribute to DeFi protocols** and want to understand how changing exploit patterns should influence architecture, integrations, governance, and operational planning. - You **work in security, research, or auditing** and want to compare notes on how attack surfaces have evolved beyond straightforward contract vulnerabilities. - You **invest in, analyze, or allocate capital to DeFi** and need a better framework for evaluating protocol resilience, hidden dependencies, and design risk. - You **participate in DAO, governance, or community roles** and want to understand how non-code decisions can create real security consequences. - You are an **active DeFi user or power user** who wants to think more clearly about protocol trust, systemic exposure, and what “safe enough” really means in practice. - You value **smart, in-person discussion with other people in crypto** and want a room where the conversation goes beyond headlines into concrete lessons and implications.
