Web3 Oracle, which is also called the improved data source available to assist Smart Contracts, allows creating smarter Dapps using Hybrid Smart Contracts.

API3 offers a solution in first-party oracle making Web2 APIs accessible to Web3 via a lightweight API middleware, allowing for on-chain access to Web2 APIs using smart contacts. Right in early 2021, API3 partnered with different API Providers, also carrying a catalog of 150+ in API3 Alliance. API3 worked with Sovryn after successfully taking part in the Sovrynthon. Sovryn is also a decentralized lending & trading platform. It has successful integration with RSK Testnet.
