Abstract—Blockchain aggregators play an instrumental role in the evolution of blockchain technology, serving as pivotal enablers of interoperability, eficiency, and user accessibility in an increasingly decentralized digital world. However, the literature on this emerging technology is scarce and is not systematized, making it harder for practitioners and researchers to understand the field , Aggregators form the cornerstone of Lumina’s oracle stack, ensuring reliable price feeds through transparent, consensus-driven aggregation. Their modular design and comprehensive security measures provide the foundation for sophisticated DeFi applications requiring accurate, tamper-resistant data., Modular blockchains became broadly discussed last year when Celestia announced its ambitions. Since then, the modular thesis has taken off with countless data availability layers launching, encouraged by a flourishing L2 ecosystem. However, the idea of modular blockchains isn’t entirely new or something that only Celestia has worked on.

In order to make all six complementarity determining regions (CDRs) accessible for diversification, the synthetic genes were designed to be modular and mutually compatible by introducing unique restriction endonuclease sites flanking the CDRs., The DeFi space has come a long way since the early days of decentralized exchanges and experimental lending protocols, and now crypto aggregator platforms are taking center stage. In 2025, with billions in total value locked and more users onboarded every day, the industry is at a turning point — driven by tools that simplify, secure, and supercharge the trading experience.
