About this episode
In this episode of Bullish on Bitcoin Show, Alexei is joined by Philipp Zentner, CEO and co-founder of LI.FI — one of the leading cross-chain aggregation and DeFi infrastructure protocols in the space, with over $80 billion in transaction volume and more than 1,100 active B2B partners.
They go deep on the evolution of cross-chain bridging, the rise of intent-based architectures, why Bitcoin on-chain trading is still a fraction of centralised exchange volume, the case for and against tokens, and how AI is reshaping both the attack and defence landscape in DeFi security.
In this episode:
- How LI.FI was built: from bridge aggregation to a full investment API for DeFi
- The three bridge architectures explained: mint & burn, liquidity networks, and intent systems
- Why bridge aggregation is essential — and why no single design wins
- Fixed-rate quoting: why demand is still low today — and why TradFi will change that
- Why Bitcoin on-chain trading is still a fraction of CEX volume — and what's holding it back
- BOB's fixed-rate Bitcoin swap product: currently in beta testing
- Tokens: the bull case, the abuse problem, and why LI.FI built a $80B business without one
- AI in DeFi security: double-edged sword or net positive?
- Why smaller unmaintained protocols are getting systematically exploited
- The KelpDAO hack: key mismanagement, RPC node attacks, and what it tells us about the space
- DeFi vs. centralised custodians: why protocols get stronger over time — and why corruption is the bigger risk
