Euler: The DeFi Super App - Michael Bentley

Brian Crayton welcomes Michael Bentley, CEO and co-founder of Euler Labs and Euler Finance, to discuss their innovative DeFi lending protocol, Euler. Bentley explains that Euler integrates with Uniswap, allowing for the lending and borrowing of a wider range of assets, including long-tail assets beyond major cryptocurrencies like ETH, USDC, and Bitcoin. He highlights Euler's liquidation process, which operates as a fair auction, resulting in lower costs compared to other platforms.

Bentley shares his background in evolutionary game theory, which has influenced his approach to DeFi. Initially skeptical about crypto, he became interested in 2017 and began building trading bots for decentralized exchanges. His interest in DeFi grew, leading to the creation of Euler after developing a novel interest rate setting mechanism during a hackathon. Euler's liquidation mechanism utilizes a Dutch auction for bonuses rather than slashing collateral, resulting in lower liquidation costs for large borrowers.

The history of Euler reveals its evolution from a hackathon project into a flexible lending protocol. Despite being heavily audited, Euler V1 experienced a significant exploit in 2023 due to an uninitialized exchange rate, leading to a loss of $200 million. The recovery process involved extensive data tracking and negotiations with the attacker, ultimately recovering $240 million, aided by law enforcement actions.

Following the incident, the team decided to rebuild their reputation in the DeFi community, leading to the development of OliV2, which incorporates lessons learned from V1. Key insights revealed that user preferences in DeFi vary widely, prompting the creation of a modular protocol that allows for customizable credit market products. OliV2 serves as a toolkit for various DeFi protocols, enabling users to tailor products to their specific needs.

Euler operates using a modular structure with "volts," allowing for diverse collateral types and bidirectional borrowing. This flexibility positions Euler as a potential alternative to Aave, with the ability to reconstruct Aave's functionalities. Both Euler and Morpho have seen growth driven by yield-bearing stablecoins, but these strategies come with risks, particularly if stablecoins de-peg.

The conversation touches on the future of fixed-rate lending in DeFi, with a belief that demand for fixed-rate products will cater to traders with shorter time horizons. The anticipated integration of real-world assets into Euler's architecture is seen as a key area for future development, with expectations that protocols will specialize in different classes of trades.

The discussion also addresses the role of privacy in DeFi, noting the tension between the desire for privacy and the need for transparency. The potential impact of AI on DeFi is discussed, particularly in enhancing rebalancing strategies and optimizing yield through machine learning algorithms. The speaker expresses optimism about the future of DeFi and the integration of traditional finance on-chain, highlighting the current period as an exciting time filled with opportunities.
