Michal “Mehow” Pospieszalski, CEO of MatterFi | Designing Hack-Proof Web3 Systems, Cryptographic Wallets & Bybit-Proof Custody | Bitcoin.com Interviews

Michal “Mehow” Pospieszalski, CEO and co-founder of MatterFi, joins Dustin Plantholt to explain how hack-proof cryptographic wallets and provable custody systems can prevent heists like the Bybit hack — and what truly secure Web3 custody looks like in 2025.

MatterFi is building user-friendly, enterprise-grade crypto custody that surfaces infallible cryptographic proofs, allowing users and auditors to verify state and actions without trusting opaque intermediaries. Mehow breaks down the technical primitives, the real-world threats to exchanges and bridges, and why cryptographic transparency is the missing link for institutional adoption. He also discusses scalability and the potential of Ethereum’s Megaeth (MegaETH) compared to high-throughput chains like Solana.

💡 In this episode:
• How MatterFi’s wallet and custody design creates hack-proof guarantees.
• What infallible cryptographic proofs mean for user security and exchange audits.
• A technical post-mortem mindset on the $1.46B Bybit hack and prevention strategies.
• How custody, wallets, and on-chain proofs unlock institutional trust.
• Thoughts on Ethereum Megaeth vs Solana for speed, throughput, and security.

🎧 A dense, technical — yet accessible — conversation for builders, security teams, and DAOs about crypto custody, wallet security, cryptographic proofs, and the future of hack-resistant Web3 systems.
