Oracle [retired]

An on-chain oracle is a system that connects blockchain smart contracts with off-chain data sources and computational resources, enabling smart contracts to respond to real-world information.

Due to low adoption Brewlabs decided to retire Orcale.

Tip: Oracles are available on Base network only.

About

Brewlabs offers free and premium tier access to oracle data for use across the community. We offer a growing library focusing on mixed on-chain and real world asset price oracles for smart contracts. The oracles are updated every minute with fresh data to highlight its real-time nature. Oracles are not a direct consumer product, but rather an infrastructure tool available for developers to adopt for their own protocols or projects.

What is an example of an Oracle?

Common types of on-chain oracles include:

Price oracles: Providing asset price data (our library)
Data oracles: Supplying real-world information like weather, sports results, etc.
Computation oracles: Performing complex calculations off-chain and providing results
Identity oracles: Verifying real-world identities
Event oracles: Reporting when specific real-world events occur

How to use the Brewlabs Oracle?

Visit the Oracle smart contract getAssetByKeySymbol
Enter your symbol
- Example "COIN" and hit query
Receive the asset string key,
- Example "0x94d28cfe178ae84130ce540d5dadabd088b301735941a744d121b4926572ece0"
Enter the asset string into the assetPricesfunction
Receive price (consider 8 decimal places)
- Example "COIN = 21255000000" ($212.55 USD)
