Inside LYS: Graph Databases as a Foundation for Advanced Strategies in DeFi

The DeFi ecosystem has expanded at a breakneck pace, introducing a highly fragmented liquidity landscape across thousands of blockchains and protocols. This rapid growth presents significant challenges, interconnected assets and protocols create complex relationships that traditional yield optimization and risk management tools struggle to handle efficiently. The result is often below-par decision-making and heightened risk exposure, as these conventional tools can't keep up with the constant data flow and interdependencies within the DeFi space.

Central to the LYS Protocol is a powerful, scalable solution… graph databases. These databases are specifically designed to model and analyze the intricate relationships between protocols, liquidity pools, assets, transactions, and more, in real-time. 

Let’s explore the technical role that graph databases play in enabling LYS to deliver scalable, real-time yield optimization, risk management, and cross-protocol liquidity aggregation.

What Are Graph Databases?

Graph databases use nodes (representing entities) and edges (representing relationships) to model complex, interconnected data. In the DeFi space, where assets and protocols interact dynamically across chains, this approach is essential. Traditional relational databases, with their rigid table structures, fail to capture the fluidity and evolving nature of decentralized networks. In contrast, graph databases excel at representing complex networks (like in DeFi) where relationships between nodes continuously change.

In DeFi, these nodes represent protocols, tokens, staking pools, or liquidity pools, etc. while edges track interactions between them, such as liquidity movement, collateral transfers, staking relationships, or governance changes. Graph databases enable LYS to map these complex interactions in a way that not only reflects the current state of the network but also allows for real-time adjustments as these relationships evolve.

Why do they matter?

The decentralized nature of DeFi means that protocols and assets are not siloed but are constantly interacting with one another. For example, staking in one protocol might affect liquidity in another, and liquidity provision might be collateralized across multiple chains. Graph databases efficiently model these interrelationships, making them ideal for cross-chain DeFi.

Additionally, as DeFi expands, the speed of querying large datasets becomes increasingly important. Graph databases like Neo4J are optimized for low-latency querying even at scale, which is essential when assessing risk and yield in real-time.

How LYS Uses Graph Databases for Yield Optimization and Risk Management

LYS harnesses graph databases for a range of yield optimization functions, including data modeling, cumulative risk and return calculations, path evaluation, and scalability.

Graph Data Modeling

Graph databases within LYS represent protocols, assets, and investment opportunities as nodes, while relationships between them are represented as edges. Each node is tagged with metadata such as protocol-specific APY, slashing risks, collateral types, and security audit histories. These relationships are not static, they evolve with on-chain events, such as liquidity movements, governance votes, or yield fluctuations. 

From a graph theory perspective, nodes can be seen as vertices and the relationships between them as edges. Each edge in the graph is directional, meaning the flow of assets or risks can be captured and measured as they move between protocols. For instance, in LYS, a "liquidity provision" edge might connect a staking pool (node) to its governance mechanism (node), capturing how liquidity risk influences governance decisions.

By modeling DeFi assets and their behaviors in a graph, LYS is capable of tracking how changing parameters (such as APY or token prices) in one protocol propagate across others. This allows LYS’s Smart Capital Navigator to dynamically adjust investment paths as new opportunities or risks arise.

Additionally, the fluid, interconnected nature of DeFi makes graph databases an ideal solution for real-time data representation. In LYS, relationships such as asset correlations and protocol dependencies can be updated with every new block or transaction, ensuring users have access to the most current data when deploying or adjusting capital.

Cumulative Risk and Return Calculations

In DeFi, risk is rarely confined to a single protocol or asset. Instead, risks are distributed across an entire network, with liquidity volatility, slashing events, governance changes, and smart contract vulnerabilities all compounding to impact overall portfolio health. Traditional risk models, which analyze each protocol in isolation, fail to capture the broader, systemic risks inherent in DeFi. Graph databases allow LYS to model these cumulative risks more effectively by tracking how risks flow and accumulate across related nodes in the DeFi graph.

In graph-based models, centrality measures like betweenness centrality and eigenvector centrality are applied to identify critical points in the network. For instance:

  • Betweenness centrality helps LYS evaluate how much a particular protocol is involved in liquidity flows across the DeFi ecosystem, and thus its exposure to systemic risk.
  • Eigenvector centrality enables LYS to understand the influence a protocol has over others in terms of yield generation or liquidity.

By using these advanced graph measures, LYS builds a comprehensive risk profile that accounts for how risks compound as they flow through interconnected protocols. This risk modeling is continuously recalculated in real time, enabling LYS to adjust portfolio risk scores dynamically as conditions change.

Additionally, LYS's cumulative risk calculations are not just retrospective. As new governance decisions are made or liquidity flows change, LYS updates its risk scores across the network to keep users ahead of potential issues. By recalibrating these risk scores in real-time, LYS allows users to automatically rebalance their portfolios to reduce exposure to newly arising risks, without needing to constantly monitor the market themselves.

Path Evaluation

Path evaluation is a critical aspect of determining the most efficient routes for capital deployment in DeFi. A path in the graph corresponds to a sequence of nodes and edges, where each step in the path represents a transition of capital across the ecosystem. Evaluating these paths involves assessing multiple factors, such as transaction costs, liquidity availability, and risk-return tradeoffs.

Graph algorithms like Dijkstra’s shortest path algorithm can be adapted in DeFi to find not just the shortest path but the most risk-adjusted path. LYS integrates similar algorithms to evaluate:

  • Risk-adjusted returns: Minimizing risk exposure while ensuring acceptable yield.
  • Liquidity constraints: Ensuring capital deployment does not cause liquidity slippage that could erode returns.
  • Transaction costs: Accounting for gas fees and cross-chain bridging costs.

In LYS, the AI Pathfinder uses graph algorithms to evaluate thousands of paths in real time, ensuring users are directed to the strategies that align with their risk profiles and yield expectations. Paths are continuously reevaluated as market conditions shift, providing a constant flow of updated strategies.

Users can set their own risk limits, and LYS dynamically adjusts the evaluated paths to stay within these constraints, factoring in potential changes to protocol risk scores and yield fluctuations.

Scalability

As the DeFi ecosystem grows, so does the volume and complexity of data that must be processed. Graph databases offer several features that make them particularly well-suited for scaling in a decentralized context. LYS uses several strategies to ensure that the infrastructure remains scalable and efficient, even as the number of protocols, assets, and transactions continues to increase.

One key feature is partitioning and sharding, where large graphs are split into smaller subgraphs. This enables parallel processing and minimizes query times even when handling massive datasets. For instance, LYS may partition its graph by blockchain (Ethereum, BSC, Polygon), enabling cross-chain analysis without getting overwhelming.

Additionally, caching and precomputed queries are used to optimize performance. Frequently queried nodes, such as popular yield protocols or high-liquidity pools, are cached for faster retrieval. This is crucial in LYS, where real-time path evaluations and risk assessments are a constant requirement. Precomputing common queries (such as APY or risk score calculations) means LYS can respond quickly to user requests without needing to recalculate from scratch every time.

Finally, parallel processing enables LYS to handle multiple threads simultaneously, a necessity when evaluating large, interconnected datasets. By running parallel processes, LYS can assess multiple protocols and assets in real-time, ensuring low-latency decision-making.

By indexing critical parameters like APY and risk scores and precomputing frequent queries, LYS is able to provide users with low-latency responses when adjusting portfolios or deploying capital, even as the underlying dataset grows with more assets and protocols.

Conclusion

DeFi is often defined by its complexity and constant evolution, and therefore graph databases become not just a technical choice… but a necessity. By enabling real-time modeling of interconnected protocols and assets, performing cumulative risk calculations, and optimizing capital deployment paths, LYS provides users with a robust, data-driven platform for yield optimization and risk management.

The scalability of graph databases ensures that as DeFi continues to grow, LYS remains capable of delivering accurate, real-time insights without sacrificing performance.
