Abstract

Chitra et al. (2025) claim that Target Weight Mechanism (TWM) in Perpetual Demand Lending Pools (PDLPs) can lower the delta of the portfolio under certain condition. We prove that their condition is self-contradictory. Furthermore, we prove an impossibility result that no TWM can lower the delta uniformly.

Complexity vs Empirical Score

  • Math Complexity: 6.5/10
  • Empirical Rigor: 2.0/10
  • Quadrant: Lab Rats — theoretically deep, empirically untested

Why this score: The paper provides a formal mathematical counter-proof and an impossibility result refuting prior claims regarding Target Weight Mechanisms in DeFi lending pools. While highly theoretical with strong mathematical rigor, it lacks empirical backtesting or real-world transaction data validation.
