Demystifying MPC for coSNARKs: How to Collaboratively Prove Sumthing - DeFi Security Summit 2025
Speaker: Vesselin Velichkov, ZK Cryptography Researcher, OpenZeppelin We present Sumthing, a toy SNARK protocol designed to illustrate how multiple parties can collaboratively generate a proof of knowledge using MPC. With worked-out Sumcheck-based examples, we demystify MPC's role in coSNARKs and verifiable outsourced computation. About DSS Every year, DSS brings together top minds in blockchain, auditing, and security — from white-hat hackers and protocol developers to academic researchers and industry leaders. The goal? To tackle the most pressing issues in DeFi security head-on — from smart contract exploits and cross-chain vulnerabilities to governance threats and beyond. https://defisecuritysummit.org/

Formal Verification of Uniswap v4 Hooks - DeFi Security Summit 2025
Speaker: Jochen Hoenicke, Formal Verification Researcher, Certora In this talk you will learn the basics of formal verification and how to apply this to Uniswap hooks. We will show how we can formally model the Uniswap v4 infrastructure, particularly the PoolManager, to find bugs in the interaction between the hook and the pool and protect against unexpected attack vectors.

OpSec Fundamentals Web3: Hands-On Tools and Recom. for Everyday Security - DeFi Security Summit 2025
Speaker: Sven Igl, Security Researcher, Sherlock Individual OpSec is vital in Web3 to counter phishing and exploits. This workshop builds awareness and explores a variety of tools/techniques as examples, such as QubesOS for isolation, DangerZone for document interactions, secure multisig handling, and more. Practice mitigations for real-world personal security.

Streamlining Security Audits with AuditHub - DeFi Security Summit 2025
Speaker: Kostas Ferles, CTO, Veridise Security audits are complex and obscure processes that involve many critical decisions. AuditHub streamlines audits by introducing transparency and automation. The result? Efficient and better documented security audits for analysts and developers.Security audits are complex and obscure processes that involve many critical decisions.

The Art of Manually Guided Fuzzing - DeFi Security Summit 2025
Speaker: Jan Kalivoda, Tech Lead, Ackee Blockchain Manually Guided Fuzzing represents a paradigm shift in testing. Unlike random/property-based fuzzing, this approach puts testing back under your control, directing the process toward vulnerabilities with surgical precision.

What We Talk About When We Talk About DeFi in Europe - DeFi Security Summit 2025
Speaker: Vyara Savova, Policy Strategist, EUCI As the EU’s MiCA regulation begins to bite, questions of liability, governance and security in DeFi are no longer theoretical. This workshop probes how legal risk attaches to code—through smart contract design, MEV dynamics, and decentralised architecture.
