Piercing the Veil of TVL: DeFi Reappraised

2024-04-17

AI Summary

Traditional DeFi metrics—particularly Total Value Locked (TVL)—are vulnerable to double-counting induced by token wrapping, leverage, and synthetic asset replication, leading to inflated valuations and poor robustness. Method: This paper introduces Total Redeemable Value (TVR) as a foundational, economically grounded alternative to TVL. We formally model systemic double-counting and financial contagion arising from derivative tokens in DeFi, and propose a novel TVR evaluation framework integrated with a DeFi money multiplier model, network-based analysis, on-chain econometrics, and contagion modeling. Contribution/Results: Empirical analysis reveals a substantial TVL–TVR gap—e.g., TVL/TVR ≈ 2 on December 2, 2021 (gap: $13.99B)—and nonlinear market responses: a 25% ETH price decline triggers over $1B additional TVL erosion, whereas TVR exhibits markedly greater resilience during downturns. TVR thus provides a more reliable benchmark for DeFi risk assessment and regulatory oversight.

Abstract

Total value locked (TVL) is widely used to measure the size and popularity of decentralized finance (DeFi). However, TVL can be easily manipulated and inflated through"double counting"activities such as wrapping and leveraging. As existing methodologies addressing double counting are inconsistent and flawed, we propose a new framework, termed"total value redeemable (TVR)", to assess the true underlying value of DeFi. Our formal analysis reveals how DeFi's complex network spreads financial contagion via derivative tokens, increasing TVL's sensitivity to external shocks. To quantify double counting, we construct the DeFi multiplier, which mirrors the money multiplier in traditional finance (TradFi). This measurement reveals substantial double counting in DeFi, finding that the gap between TVL and TVR reached $139.87 billion during the peak of DeFi activity on December 2, 2021, with a TVL-to-TVR ratio of approximately 2. We conduct sensitivity tests to evaluate the stability of TVL compared to TVR, demonstrating the former's significantly higher level of instability than the latter, especially during market downturns: A 25% decline in the price of Ether (ETH) leads to a $1 billion greater non-linear decrease in TVL compared to TVR via the liquidations triggered by derivative tokens. We also document that the DeFi money multiplier is positively correlated with crypto market indicators and negatively correlated with macroeconomic indicators. Overall, our findings suggest that TVR is more reliable and stable than TVL.
