Online Webinar #13: Multisig & Cross-Chain

​🔐 Bitcoin Multisig & Cross-Chain Tokens
Two technologies. Two chains. Two world-class builders. One event.

​Join us for a power-packed live session featuring Ben Kaufman and Ben Weinberg, two of the sharpest minds in Web3 infrastructure, sharing the stage for the first time.

​🧠 What You’ll Learn

​Part 1 – Bitcoin Multisig with Ben Kaufman
Go deep into the mechanics of Bitcoin multisig, from protocol-level theory to real-world wallet operations. Whether you're building for self-custody, security infrastructure, or just want to understand how serious Bitcoin users manage risk—this is your masterclass.

​• How Bitcoin multisig works at the protocol level
• Common wallet setups and real-world custody architectures
• Creating and managing multisig wallets step-by-step
• Threat models, security best practices, and operational risks
• Tools, libraries, and frameworks used in production
• Common mistakes when implementing multisig

​Part 2 – Cross-Chain Tokens with Ben Weinberg
Learn how tokens actually move across chains in production. Ben will break down the SUI ↔️ EVM bridge architecture, messaging standards, and how Interop Labs is building the future of cross-chain token interoperability.

​• How cross-chain token transfers work in practice
• Architecture behind SUI ↔️ EVM interoperability
• Standards, bridges, and messaging layers involved
• Security assumptions & common attack surfaces
• Live walkthrough of Interop Labs tooling
• Real-world examples of production cross-chain apps
