02 / UNDER THE HOOD

Technology & network design

Oracle networks aggregate information from data providers and deliver signed reports to blockchains. Other products include cross-chain communication and automated execution services.

03 / THE ECOSYSTEM

How it is used

Price feeds, proof of reserve, cross-chain messaging, automation and tokenized asset infrastructure.

04 / THE BIG PICTURE

What makes it different

It focuses on connecting blockchains with external systems rather than serving as a general-purpose base-layer currency.

05 / KNOW THE RISKS

Risks & trade-offs

Oracle dependency, configuration mistakes, bridge or cross-chain exposure, token economics and smart-contract bugs.
