You just HAD to be there. Good news! ETHSofia is coming back on September 24th! Some rooms just have the right energy. ETHSofia 2025 brought together Ethereum builders, researchers, and technical teams for two days of real depth at Sofia Tech Park. Privacy infrastructure. Smart contract security. Consumer DeFi. The conversations that matter. Super Early Bird combo tickets for @BWBulgaria (ETHSofia + F3) are live now at the best price they'll be.

He came to DeFi from research science, bringing a PhD from the University of Melbourne with him, and went on to lead product and protocol development at Bancor — one of the pioneers of decentralized liquidity and onchain trading infrastructure. Today, @MBRichardson87 is leading Carbon DeFi, @Bancor's flagship trading protocol, focused on strategy-based liquidity, capital efficiency, and MEV-resistant trading across Ethereum and other major ecosystems. At ETHSofia, Mark will break down where current DEX and AMM designs reach their limits, introduce a new approach to exchange mechanism design based on pricing behavior, and explore what this could unlock for builders through new liquidity models and more predictable execution. And he’s joining us on September 24 in Sofia for a deep dive into the future of DeFi infrastructure.

Our Diamond Sponsor @UEB3ventures  is growing their team and they want to hear from you! UEB3 manages $50M in digital assets and is expanding into real-world asset tokenisation. Think real estate, collectibles, alternative investments, all on-chain. They have offices in Sofia, Frankfurt, Dubai, and Bangkok, and they're building out the team behind the product. Two roles are open right now: 📣 Social Media Manager (Sofia, Hybrid) If you live and breathe crypto culture, CT, and digital storytelling, this one's for you: linkedin.com/jobs/view/4413… ⚙️ Hybrid CTO / Full-stack Web3 Tech Lead (Sofia) React, Next.js, Node.js, and a front-row seat to building a Web3 tokenisation platform from the ground up: linkedin.com/jobs/view/4413… If either of these sounds like your next move, apply directly or send your CV to career@ueb3fund.com linkedin.com/company/ueb3-v…

See you in Sofia on September 24. Early Bird Tickets are now on sale: blockchainweek.bg/get-tickets

Cross-chain infrastructure has become one of the most critical battlegrounds in web3. As liquidity, applications, and users move across ecosystems, security is no longer just a protocol concern, it’s a coordination problem across chains. That’s exactly why we’re excited to welcome @tkaraivanov to ETHSofia! Todor is Blockchain Integrations Lead at @chainlink, where he has spent more than five years working on decentralized infrastructure and interoperability systems. With a background spanning blockchain, game development, hosting infrastructure, and information security, he brings a deeply technical perspective on how secure distributed systems are actually built. At ETHSofia, Todor will dive into cross-chain security, including the risks, assumptions, and infrastructure challenges emerging as interoperability becomes foundational to the next generation of blockchain applications. See you in Sofia on September 24

Klara Kovačević @klarakova is joining ETHSofia as a speaker! She's Ecosystem Lead at @chain_security - the team auditing smart contracts for Circle, Sky, Aave, and Curve. Working at the intersection of security and community, connecting builders with the people keeping what they ship secure. Before that, she spent time at Google's EMEA headquarters in Dublin, advising clients on digital growth and overseeing €20 million in annual advertising investments. She also serves on the board of Alice in Blockchains, working to make blockchain technology accessible to a wider audience. We're excited to welcome her on the ETHSofia stage🎙️

Jonathan Riss (@allypry) is joining #ETHSofia as a speaker. He's a Blockchain Intelligence Analyst at @CertiK, one of the leading security audit and intelligence firms in Web3. His work is on the OSINT and de-anonymisation side: tracing illicit flows on-chain, identifying malicious actors behind wallet addresses, and turning what looks like noise into actionable intelligence. On-chain forensics is one of the topics our audience keeps coming back to every year. We're glad to have someone doing it at this level on the stage in Sofia this September.

@Lalilulel0o_ @AaveChan @aave @Marczeller Haha, not so fast! The shirt is already claimed by Marc... BUT typo-spotting comes with perks. We’ll have banitsa waiting for you at registration. See you in September 🙌

@ETHSofiaBG @AaveChan @aave @Marczeller Hahaha really? How lucky i am. Do you have XXL?

Before that: Consensys, Coinhouse (France's first regulated CASP), and a front-row seat to @aave's origin story as part of the EthLend team that launched V1. He also co-founded @Ethereum_France and helped organise the first @EthCC in Paris in 2015! @Marczeller is joining us at ETHSofia 2026!

@Lalilulel0o_ @AaveChan @aave Whoops… our bad! @Marczeller, this typo has activated an ancient Bulgarian ritual. This action of ours now legally obligates us to buy you a shirt. Drop your size👀

@ETHSofiaBG @AaveChan @aave Is it Marc or Mark?

For years he analyzed DeFi protocols, ran live onchain experiments, and built DeFi France into the main French-speaking community in the space. Then he watched stablecoins abandon decentralization one by one and decided that analyzing it wasn't enough. @TokenBrice is the Founder of @polarisfinance_, DeFi's answer to stablecoin centralization, and the creator of @PharosWatch, a stablecoin monitoring dashboard tracking 156 assets across every major chain. He's joining us as a speaker at ETHSofia 2026!

She shipped product through the Merge, built mempool tooling at Blocknative, and co-founded a blind computation platform when the field was still being defined. 10 years across protocol, infrastructure, and product in web3. @sajidazouarhi is the CPO at @get_optimum, building the universal data acceleration network for blockchains using RLNC. And she's joining us at #ETHSofia26 Come to Sofia this September and understand why we are so excited to have her speak 👉 blockchainweek.bg

Minutes after the Artemis II crew restored communications with Earth, they realised something far more critical than breaking records had occurred. We were asked not to share this. We're sharing it anyway. 🎟️ Early Bird tickets to @BWBulgaria are now live. Don't make their mistake.

Security is at the core of what we build. Proud to have @PashovAuditGrp backing @BWBulgaria 🙌🇧🇬

Wow, the day we warned you about is finally here!

Krum Pashov has spent years answering the hardest questions that keep web3 founders up at night. Under his leadership, @PashovAuditGrp has completed 400+ audits and helped protect over $100B in funds, making him one of the most recognized names in web3 security. Last year he also answered one of the most asked questions in crypto. IYKYK :) @pashov is joining us at ETHSofia on September 24!

Web3Voyager is joining us as an official media partner. They help builders and investors discover Web3 events worldwide and we're glad to be on their radar!
