Problem statement :

DeFi apps have exploded in use but have also proved unreliable. Stress testing of DeFi apps for the Cardano environment is required.

Describe your solution to the problem

Tools to assist developers in the verification of DeFi design and agent-based simulation of DeFi prototypes will stress-test proposed apps.

Relevant experience

The Photrek team provides expertise in the design, analysis, and evaluation of complex open-source software systems.

Plan Impact

  • The Ruggedized DeFi project will provide developers with tools and analysis to assess the potential vulnerabilities of their decentralized financial applications.
  • Two domains of analysis will be the initial focus
  • Use of Category Theory to translate proposed applications into structured models which can be developed in Plutus and Haskell.
  • Use of agent-based simulations to stress test the dynamics of the application in a complex marketplace.
    Proposed Outcome
    To demonstrate the effectiveness of the tools and analysis, the Photrek team will complete a stress-test of the Uniswap type decentralized exchange. Uniswap creates a liquidity pool by maintaining the ratio between assets. Makers add an equal value of two assets rather than specify buy and sell prices. The exchange price is determined by the impact of a proposed trade on the maintenance of the ratio between the two assets. As the demand to buy one asset increases, thus reducing the quantity of that asset in the pool, the exchange price is adjusted to maintain an equal valuation of the two assets in the pool.
    As Cardano developers consider implementing Uniswap-type decentralized exchanges and related DeFi apps, the rigorous quality which the Cardano community has applied to the Cardano network needs to be maintained in the apps’ development. While Uniswap has been enormously successful as a decentralized exchange with $1 Million in daily transactions, this is still orders of magnitude smaller than centralized exchanges such as Binance $16 Billion in daily transactions. Two questions that our analysis will address is:
  • How can the rigor of functional programming and its related modeling with Category Theory be used to improve the long-term reliability of the codebase for a decentralized exchange such as Uniswap?
  • How will the Uniswap-type liquidity pools react in a stressed market? While the mathematics of maintaining equally valued assets in each pool has been demonstrated to be operational, will this formulation be robust to the stresses of a severe change in the value of a particular asset? Are there modified formulations that can make the markets more resilient?
    Project Tasks, Budget, & KPI
    Identify Decentralized Exchanges Vulnerabilities ($7,000 – Month 1)
  • Describe 5 potential software vulnerabilities and identify 2 for further analysis
  • Describe 5 marketplace stressing scenarios and identify 2 for further analysis
  • Specify how these vulnerabilities impact Uniswap-type decentralized exchanges
    Prototype model and simulation of Uniswap-type vulnerabilities ($18,000 – Month 3)
  • Develop agent-based simulation of the 2 marketplace stressing scenarios
  • Develop system model using category theory to address the two software vulnerabilities
    Complete experiments analyzing Uniswap-type vulnerabilities ($18,000 – Month 5)
  • What are the financial risks of software vulnerabilities relative to the market size?
  • What are the financial risks of the trading dynamics relative to the market size?
    Final report including the availability of vulnerability analysis for other DeFi projects ($6,000 – Month 6)
  • Have we identified two DeFi development teams that can utilize and incorporate the analysis?
  • Have we provided adequate open-source tools for teams to build upon the results of the project.
    Team Member Roles
    Dr. Kenric Nelson – President, Photrek – Nelson will apply his expertise in leading open-source software development and in the modeling and analysis of complex systems.
    Dr. Andre Vilela – Associate Professor, University of Pernambuco, Brazil – Vilela will develop an agent-based simulation of the marketplace vulnerabilities in decentralized exchanges.
