Abstract:
Decentralized Finance (DeFi) has redefined conventional financial services by enabling intermediary-free peer-to-peer transactions, yielding a wealth of open-source transaction data. In this dynamic DeFi landscape, the emergence of Layer 2 (L2) solutions holds the potential to significantly enhance network efficiency and scalability, surpassing the capabilities of Layer 1 (L1) infrastructure. Nevertheless, the precise impact of L2 solutions remains obscured by the scarcity of transaction data indices that provide meaningful economic insights for empirical analysis. This research endeavors to bridge this critical knowledge gap through a rigorous analysis of raw transactions obtained from Uniswap, a pivotal decentralized exchange (DEX) at the core of the DeFi ecosystem. Our dataset comprises an expansive collection of over 50 million transactions, originating from both Layer 1 (L1) and Layer 2 (L2) networks. Furthermore, we curate a comprehensive repository of daily indices derived from transaction trading data across prominent blockchain networks, including Ethereum, Optimism, Arbitrum, and Polygon. These indices illuminate vital network dynamics, encompassing adoption trends, scalability evaluations, decentralization metrics, wealth distribution profiles, and other pivotal facets within the DeFi landscape. This dataset serves as an invaluable resource, empowering researchers to unravel the intricate relationship between DeFi and Layer 2 solutions, thereby advancing our understanding of this evolving ecosystem.
