Total Value Locked (TVL) aims to measure the aggregate value of cryptoassets deposited in Decentralized Finance (DeFi) protocols. Although blockchain data is public, the way TVL is computed is not well understood. In practice, its calculation on major TVL aggregators relies on self-reports from community members and lacks standardization, making it difficult to verify published figures independently. We thus conduct a systematic study on 939 DeFi projects deployed in Ethereum. We study the methodologies used to compute TVL, examine factors hindering verifiability, and ultimately propose standardization attempts in the field. We find that 10.5% of the protocols rely on external servers; 68 methods alternative to standard balance queries exist, although their use decreased over time; and 240 equal balance queries are repeated on multiple protocols. These findings indicate limits to verifiability and transparency. We thus introduce ``verifiable Total Value Locked'' (vTVL), a metric measuring the TVL that can be verified relying solely on on-chain data and standard balance queries. A case study on 400 protocols shows that our estimations align with published figures for 46.5% of protocols. Informed by these findings, we discuss design guidelines that could facilitate a more verifiable, standardized, and explainable TVL computation.

In the era of continuously increasing demand for bandwidth and revolutionary wireless technologies, efficient spectrum management is essential. This paper proposes a novel multi-tier tokenization approach for dynamic spectrum management. Leveraging the concept of heterogeneous tokenization of spectrum bands, we develop a decentralized framework based on blockchain technology that enables the sharing of spectrum among users. The spectrum space is represented by multi-planes, the first plane consists of unique spectrum bands converted into NFTs for long-term allocations, while the second plane involves subdividing these NFT spectrum bands for short-term usage by retail users through fungible tokens. The fungible tokens are dynamically traded and mapped using particle swarm optimization (PSO) to manage demand and supply. The paper presents formal models of the involved entities and algorithms for creating multi-tier tokens, dynamic token trading and demand-supply mapping using PSO. To enhance privacy, a zero-knowledge proof (ZKP) based approach is employed for user authentication. The proposed framework offers a secure, transparent, and scalable solution for spectrum management, addressing the limitations of traditional centralized approaches. Simulation results demonstrate the effectiveness of the framework in dynamic spectrum access, while providing privacy-aware and scalable solutions suitable for future wireless networks, including 6G.
The rapid evolution of Decentralized Finance (DeFi) has introduced innovative financial services, offering accessibility, efficiency, and transparency. However, the integration of DeFi into global capital markets presents systemic risks, including liquidity shocks, smart contract vulnerabilities, and regulatory arbitrage. This review explores the intersection of DeFi protocols with systemic risk frameworks to enhance capital market stability and regulatory oversight. By analyzing risk assessment methodologies, stress-testing mechanisms, and governance models, the study highlights strategies for mitigating financial contagion and ensuring market resilience. Furthermore, it examines regulatory approaches, such as real-time compliance monitoring and cross-border coordination, to bridge the gap between decentralized ecosystems and traditional financial regulations. Through case studies and empirical data, this paper underscores the importance of integrating robust risk frameworks with DeFi innovations to foster sustainable financial markets. The findings contribute to ongoing discussions on balancing financial innovation with risk management, providing insights for policymakers, regulators, and industry stakeholders navigating the evolving landscape of digital finance.
In this chapter, structures that generate yield in cryptofinance will be analysed and related to leverage. While the majority of crypto-assets do not have intrinsic yields in and of themselves, similar to cash holdings of fiat currency, revolutionary innovation based on smart contracts, which enable decentralised finance, does generate return. Examples include lending or providing liquidity to an automated market maker on a decentralised exchange, as well as performing block formation in a proof of stake blockchain. On centralised exchanges, perpetual and finite duration futures can trade at a premium or discount to the spot market for extended periods with one side of the transaction earning a yield. Disparities in yield exist between products and venues as a result of market segmentation and risk profile differences. Cryptofinance was initially shunned by legacy finance and developed independently. This led to curious and imaginative adaptions, reminiscent of Darwin’s finches, including stable coins for dollar transfers, perpetuals for leverage, and a new class of exchanges for trading and investment.
Effective risk management solutions become absolutely crucial when financial markets embrace distributed technology and decentralized financing (DeFi). This study offers a thorough survey and comparative analysis of the integration of artificial intelligence (AI) in risk management for distributed arbitrage systems. We examine several modern caching techniques namely in memory caching, distributed caching, and proxy caching and their functions in enhancing performance in decentralized settings. Through literature review we examine the utilization of AI techniques for alleviating risks related to market volatility, liquidity challenges, operational failures, regulatory compliance, and security threats. This comparison research evaluates various case studies from prominent DeFi technologies, emphasizing critical performance metrics like latency reduction, load balancing, and system resilience. Additionally, we examine the problems and trade offs associated with these technologies, emphasizing their effects on consistency, scalability, and fault tolerance. By meticulously analyzing real world applications, specifically centering on the Aave platform as our principal case study, we illustrate how the purposeful amalgamation of AI with contemporary caching methodologies has revolutionized risk management in distributed arbitrage systems.

ABSTRACT Uniswap is a system of smart contracts on the Ethereum blockchain and is the largest decentralized exchange with a liquidity balance worth up to 4 billion USD and daily trading volume of up to 7 billion USD. It is a new model of liquidity provision, so‐called automated market making. For this new market form, we characterize equilibrium in the liquidity pools. We collect all 95.8 million Uniswap interactions and compare this automated market maker (AMM) to a centralized limit order book. We document absence of long‐lived arbitrage opportunities, and show conditions under which the AMM dominates a limit order market.
Decentralized finance (DeFi) has revolutionized the financial landscape, with protocols like Uniswap offering innovative automated market-making mechanisms. This article explores the development of a backtesting framework specifically tailored for concentrated liquidity market makers (CLMM). The focus is on leveraging the liquidity distribution approximated using a parametric model, to estimate the rewards within liquidity pools. The article details the design, implementation, and insights derived from this novel approach to backtesting within the context of Uniswap V3. The developed backtester was successfully utilized to assess reward levels across several pools using historical data from 2023 (pools Uniswap v3 for pairs of altcoins, stablecoins and USDC/ETH with different fee levels). Moreover, the error in modeling the level of rewards for the period under review for each pool was less than 1%. This demonstrated the effectiveness of the backtester in quantifying liquidity pool rewards and its potential in estimating LP's revenues as part of the pool rewards, as focus of our next research. The backtester serves as a tool to simulate trading strategies and liquidity provision scenarios, providing a quantitative assessment of potential returns for liquidity providers (LP). By incorporating statistical tools to mirror CLMM pool liquidity dynamics, this framework can be further leveraged for strategy enhancement and risk evaluation for LPs operating within decentralized exchanges. • Develop a methodology for backtesting liquidity provision in a CFMM. • Enhance CFMM backtesting by leveraging GPU acceleration for faster computation. • Showcase the practicality of CFMM backtesting using actual Uniswap pool data.

Compound Finance is a decentralized lending protocol that enables the secure and efficient borrowing and lending of cryptocurrencies, utilizing smart contracts and dynamic interest rates based on supply and demand to facilitate transactions. The protocol enables users to supply different crypto assets and accrue interest, while borrowers can avail themselves of loans secured by collateralized assets. Our collaboration with Compound Finance focuses on harnessing the power of the Chainrisk simulation engine to optimize risk parameters of the Compound V3 (Comet) protocol. This report delineates a comprehensive methodology aimed at calculating key risk metrics of the protocol. This optimization framework is pivotal for mitigating systemic risks and enhancing the overall stability of the protocol. By leveraging Chainrisk's Cloud Platform, we conduct millions of simulations to evaluate the protocol's Value at Risk (VaR) and Liquidations at Risk (LaR), ultimately providing recommendations for parameter adjustments.
In decentralized finance, any individual can pool their assets into an automated market maker (AMM) -- herein we focus on the constant product market maker (CPMM) -- in exchange for a claim on a fraction of future pool assets and fees earned from the market making operations. This position is represented by a liquidity token, whose prevailing on-chain price is effectively the initial deposited assets. Though this price is well-defined, we treat the liquidity token as a derivative position in the prices of the underlying assets for the CPMM in order to deduce risk-neutral pricing and hedging formulas, not dissimilar to the Black-Scholes result. Adopting this perspective, in a frictionless environment, hedging the CPMM liquidity token under fair valuation should produce a riskless process, which therefore grows at the risk-free rate, something that is not seen in empirical case studies under the prevailing price. With our novel pricing formula, we construct a method to calibrate a volatility to data which provides an updated (non-market) valuation which is consistent with the (near-continuous) replication strategy out-of-sample. We conclude with a discussion of novel AMM design considerations motivated by this derivative-pricing perspective.
Related party transactions (RPTs) can serve as channels for the spread of credit risk events among blockchain firms. However, current credit risk-assessment models typically only consider a firm’s individual characteristics, overlooking the impact of related parties in the blockchain. We suggest incorporating RPT network analysis to improve credit risk evaluation. Our approach begins by representing an RPT network using a weighted adjacency matrix. We then apply DANE, a deep network embedding algorithm, to generate condensed vector representations of the firms within the network. These representations are subsequently used as inputs for credit risk-evaluation models to predict the default distance. Following this, we employ SHAP (Shapley Additive Explanations) to analyze how the network information contributes to the prediction. Lastly, this study demonstrates the enhancing effect of using DANE-based integrated features in credit risk assessment.

Cardano is a blockchain protocol based on proof-of-stake and an extended UTXO model which also supportsarbitrary smart contracts. Its primary currency, Ada, is cur-rently one of the global top ten cryptocurrencies with amarket cap of more than 16 billion USD. In Cardano, newblocks are produced by stake pools. Any holder of Ada candelegate their stake to a pool. The underlying proof-of-stakeconsensus protocol is Ouroboros Praos, which divides time intoa number of epochs and each epoch into a number of slots, eachcorresponding to one second. In each slot, leaders are randomlyselected to produce and add new blocks to the blockchain, withtheir selection probability being proportional to their stake.Each block can contain a sequence of transactions and blockproduction is rewarded in two ways: (i) transaction fees and(ii) monetary expansion. The producers have no control over(ii), but can optimize (i) by choosing which transactions toinclude in their blocks. Thus, they are incentivized to maximizethe total transaction fees.In this work, we consider the natural optimization problemof forming a block with maximum transaction fees givena set of unmined Cardano transactions. We show that byexploiting the sparsity of interrelations between transactions,i.e. the small treedepth of dependency-conflict graphs, it ispossible to obtain a polynomial-time algorithm that outputsoptimal blocks. We implemented our algorithm in a freeand open-source tool called Pixiu. Using Pixiu, we provideextensive experimental results over real-world transaction dataon the Cardano blockchain demonstrating that our approachincreases the block producers’ revenue by almost 1,357.82USD/day = 495,604.3 USD/year.
Decentralized Exchanges are becoming even more predominant in today's finance. Driven by the need to study this phenomenon from an academic perspective, the SIAG/FME Code Quest 2023 was announced. Specifically, participating teams were asked to implement, in Python, the basic functions of an Automated Market Maker and a liquidity provision strategy in an Automated Market Maker to minimize the Conditional Value at Risk, a critical measure of investment risk. As the competition's winning team, we highlight our approach in this work. In particular, as the dependence of the final return on the initial wealth distribution is highly non-linear, we cannot use standard ad-hoc approaches. Additionally, classical minimization techniques would require a significant computational load due to the cost of the target function. For these reasons, we propose a three-step approach. In the first step, the target function is approximated by a Kernel Ridge Regression. Then, the approximating function is minimized. In the final step, the previously discovered minimum is utilized as the starting point for directly optimizing the desired target function. By using this procedure, we can both reduce the computational complexity and increase the accuracy of the solution. Finally, the overall computational load is further reduced thanks to an algorithmic trick concerning the returns simulation and the usage of Cython.
The development of digital technologies that increase the security of payments and improve settle-ments is one of the main tasks facing regulators in the financial sector. The main reason for the in-creased attention to distributed ledger technology in the financial sector is the expectation that it will eliminate a number of problems and limitations inherent in the currently used methods of storing, ac-counting and transmitting financial information. The authors consider the advantages of the distribut-ed ledger technology in the implementation of financial transactions
Abstract Distributed ledger technology (DLT) has become a vital technological tool for digital transformation worldwide. This chapter examines the regulation of DLT in the context of European capital markets law and its definition as a security. It examines whether DLT is already regulated as a security in the traditional sense and finds that the current legal situation is sufficient. However, a definition of DLT in the context of Article 4 MiFID II would be helpful. The chapter also analyses the forthcoming EU MiCA regulation and its impact on DLT in the context of securities regulation and its relationship to current securities legislation. It provides a brief comparative overview of various approaches to regulating DLT and shows that a technology-neutral approach is preferred, even if DLT has often inspired the formulation of a universal definition. It argues that the definition of DLT in a European Capital Markets code should be separated from the definition of traditional securities and should be open to new technologies. Overall, the chapter emphasizes the importance of developing a flexible and adaptable definition of DLT that can keep pace with rapidly evolving technologies.
Abstract Although extensive research has examined the credit risk of real estate enterprises, the relationship between the political connection of real estate enterprises and these enterprises’ credit risk has not been formally studied. Using the panel data of 123 real estate listed companies in the Chinese stock market from 2008 to 2021, this paper finds a significant positive correlation between the political connection of private real estate listed companies and their credit risk. This phenomenon is attributed to the excessive debt that benefits from political connections since it may raise the credit risk of any real estate firm. Interestingly, considering that 2013 is the first year of China’s Internet finance era, we find that the popularity of Internet finance and other decentralized lending financing channels may enhance the impact of political connections on real estate credit risk. Our findings provide new micro evidence for the influencing factors and mechanism of credit risk of real estate enterprises during the recent “credit crisis” in the real estate market in China.
The conventional process of credit document verification heavily relies on manual methods, making it tedious and time-consuming. The advent of self-sovereign identity (SSI) revolutionised the landscape of credit document verification. SSI empowers individuals with complete control over their identity, ensuring privacy, trust, and security. This paper presents an in-depth exploration of SSI's application in the credit processing domain. This paper highlights the implementation of SSI using the Trust over IP framework on Hyperledger Aries, empowering borrowers to own and control the sharing of their verifiable credentials. By integrating Hyperledger Aries and SSI, a robust and interoperable blockchain-based identity framework can be built. This allows individuals to store their verifiable credentials on a distributed ledger securely and selectively disclose them to lenders as needed. This model empowers borrowers to present accurate and tamper-proof credentials, enhancing data privacy, transparency, and trust, while promoting a borrower-centric approach to sharing credentials.
