Light-weight, first-party data feeds that increase transparency, reduce cost, and scale data access for Web3.
Beacons allow smart contract developers to connect Web3 applications to continuously updated streams of off-chain data, such as the latest cryptocurrency, stock and commodities prices.
First-party transparency delivers security and efficiency
Operated by the market’s most trusted and reliable data providers, Beacons are a transparent, cost-efficient and scalable way for smart contracts to interact with the off-chain data they need.
Traditional Web3 data feeds rely on networks of 3rd-party oracle nodes. Built on API3’s first-party oracles, Beacons cut out the middlemen and the hefty fees they collect.
Data source transparent
Beacons are fed directly from the API provider to the blockchain. There are no 3rd-party oracle nodes in the middle to attack. And developers always know exactly where their data came from.
When data comes directly from a reputable source, the provider’s off-chain reputation comes with it. More transparency means more selectivity and security.
Scalable, up and down
Beacons are light-weight and highly scalable. Scale up for high performance chains. Scale down for a wide range of use cases that aren’t feasible with traditional data feeds.
Powered by BeaconsData source transparent. Data source operated.
Easy to use
Using a Beacon is as easy as making a function call.
Simple, fixed subscriptions in the native gas token. No per-call payments.
More use cases
Beacons power DeFi lending, synthetic assets, stablecoins, derivatives, coverage, NFTs and more.
