Query across raw transaction data, decoded smart contract events, stablecoin flows, RWA tracking, protocol analytics, DeFi positions, NFT activity, blockchain market research, and whatever is trending in crypto.
“The promise of analyzing crypto data through an intuitive API is enticing, but the execution fell flat, with all 13 queries resulting in failures and a frustrating HTTP 404 error on the DeFi position tracking request. If reliability is key in data analytics, this service needs significant improvements before it can be considered a viable tool for crypto enthusiasts or developers.”
“Dune is completely non-functional — every single query failed with 404s and other errors, which means the API integration itself is broken, not just edge cases. For a service built around the core promise of executing blockchain analytics queries, returning zero working results makes it worthless regardless of how fast the latency is.”
