Who actually signs the data — a middleman node, or the source itself?
Most legacy oracles use third-party node operators that re-report data they fetched elsewhere. First-party oracles cut the middleman: the data source itself signs and serves the data, improving provenance and accountability.
Built around first-party data: providers run their own Airnode, and the OEV Network returns oracle-update value to the dApp.
Aggregates 120+ first-party publishers — exchanges and market makers that publish their own prices directly to Pythnet.
For transparent provenance, API3 (managed first-party dAPIs) and Pyth (first-party publisher aggregation) lead; choose by whether you want OEV recapture (API3) or lowest latency (Pyth).
