Connecting Distributed Ledgers: Surveying Novel Interoperability Solutions in On-chain Finance

Battle Count: 80

The paper is primarily a survey of blockchain interoperability infrastructure with an illustrative regression analysis of bridge protocol revenues and volumes. While it touches on cross-chain arbitrage, liquidity aggregation, and yield optimization concepts relevant to DeFi trading, it does not develop trading strategies, pricing models, or direct quantitative trading applications. The regression framework could be adapted for studying cross-chain liquidity flows relevant to DeFi market-making, but the paper itself is not focused on trading.

The empirical component uses standard econometric techniques (pooled OLS and fixed-effects panel regressions) that are straightforward to implement. The main complexity lies in data collection and aggregation from The Graph subgraphs across multiple protocol deployments and blockchain networks. The survey/comparison component requires no implementation.

Data sources are publicly available via The Graph subgraphs (Messari's Stargate, Hop Protocol, and Across v2 subgraphs). Model specifications are fully detailed in Table 9. However, no code repository is provided, and the data aggregation methodology across multiple deployments is described only at a high level. The analysis is explicitly framed as illustrative rather than definitive.
