About this event
Uniswap V4 changes the design space for onchain applications, and this meetup focuses on two of its most interesting ideas: flash accounting and custom accounting. If you want a clearer mental model for how these mechanisms work and why they matter, this is a chance to learn in a room with people who are equally curious, technical, and engaged. This is an in-person gathering built for conversation, not just passive listening. You’ll get the context behind the concepts, practical discussion around how they affect builders and users, and the kind of real-time Q&A that helps difficult protocol topics click. About the Event At its core, this event is about understanding how Uniswap V4 expands what developers can build. Flash accounting and custom accounting are not just implementation details; they reshape how liquidity, settlement, and execution can be organized inside a protocol experience. The meetup format is designed to make those ideas more accessible. Expect a community-driven session where attendees can listen, ask questions, compare interpretations, and explore how these concepts connect to broader DeFi design patterns. Because this is an in-person event, it also creates space for the informal discussions that are often the most valuable part of technical meetups. You’ll be able to talk through edge cases, implementation questions, and product implications with other attendees face-to-face. Whether you are already following Uniswap V4 closely or just starting to explore it, the session is framed to help you move from vague familiarity to sharper understanding. What to Expect The central focus will be Uniswap V4’s flash accounting and custom accounting model, with discussion likely centered on what these mechanisms are, how they differ from previous designs, and why they matter in practice. You can expect a meetup flow that balances explanation with interaction, including space for live questions and peer discussion. Rather than treating the subject as purely abstract theory, the event is well suited to unpacking practical implications for protocol design and onchain product development. Likely points of discussion include: How flash accounting changes transaction flow and internal accounting assumptions What custom accounting enables at the pool, hook, or application-design level Why these features matter for developers building on top of modern AMM infrastructure Tradeoffs, open questions, and design considerations around flexibility and complexity Since the event is also tagged as community, networking, meetup, and social, expect a mix of structured discussion and open conversation. There should be room both for focused protocol talk and for meeting others who care about where decentralized exchange infrastructure is going next. Why Attend If Uniswap V4 has been on your reading list but still feels dense, this meetup helps bridge the gap between documentation-level understanding and practical intuition. Hearing concepts explained and debated live can make technical architecture much easier to internalize. For builders, this is a good opportunity to think beyond feature headlines and toward actual design consequences. Understanding flash and custom accounting can influence how you evaluate composability, gas patterns, state management, and new application ideas built around AMMs. For researchers, power users, and ecosystem participants, the value is in sharpening your framework. Instead of just knowing that V4 is different, you’ll leave with a better sense of where those differences are meaningful and what kinds of experimentation they may unlock. There is also real value in the room itself. Meetups like this bring together people who are actively paying attention, asking smart questions, and working through similar technical shifts. That makes the event useful not only for what is presented, but for the conversations that continue before and after the session. Practical Details This is an in-person event taking place on Thursday, May 22 at 4:00 PM GMT+3. If you learn best by being able to ask questions directly, read the room, and continue conversations afterward, the in-person format is a strong fit for this topic. The event is positioned as both a technical meetup and a social community gathering. That means you should come ready for a blend of focused subject matter and informal networking, rather than expecting a purely lecture-style session. A few useful expectations to keep in mind: Arrive ready to engage with technical ideas, even if you are still learning the details Bring your questions about Uniswap V4, protocol architecture, or practical use cases Plan for conversation before, during, or after the main discussion Expect to meet others interested in DeFi infrastructure, mechanism design, and emerging onchain tooling If Uniswap V4 is relevant to your work, your curiosity, or the future products you want to build, this meetup is a smart place to spend an afternoon.
Who should attend
If you want to understand Uniswap V4 beyond surface-level summaries, this meetup is built for you. - You’re a **smart contract developer or protocol engineer** who wants a clearer grasp of flash accounting and custom accounting, and how those ideas may shape real implementation choices. - You’re a **DeFi builder, product thinker, or founder** exploring what new AMM architecture could enable for trading, liquidity, execution flows, or entirely new product designs. - You’re a **researcher, analyst, or technically curious ecosystem participant** who wants stronger intuition for why Uniswap V4 matters and where its design differs in meaningful ways. - You’re already following **onchain infrastructure, AMMs, or protocol mechanics** and want a space to discuss ideas live instead of piecing everything together alone from threads and docs. - You value **meeting people in person** who care about the same technical topics, and you want thoughtful conversation with a community that is engaged, informed, and curious. - You do not need to be an expert, but you should be ready to engage seriously with the topic and leave with sharper questions, clearer concepts, and better connections.
