Price Feeds
The data your smart-contracts always wanted.
Your smart contracts are decentralized, transparent and composable. The data you’re using to feed them should have the same properties. Start integrating Pragma’s price feed now and unlock the power of verifiable data.

fn get_asset_price_median(oracle_address: ContractAddress, asset : DataType) -> u128 {
let oracle_dispatcher = IOracleABIDispatcher{contract_address : oracle_address};
let output : PragmaPricesResponse= oracle_dispatcher.get_data(asset, AggregationMode::Median(()));
return output.price;

Integrate existing feeds, or build new ones.
A few lines to integrate any existing data feed, a few more if you want to create a new feed using our raw data.
Our Architecture
The first provable oracle
Pragma utilizes STARK proofs to ensure data correctness. Explore how we achieve this while maintaining a 200ms latency in running the oracle, enabling composability and programmability.

Trusted by innovators
World class builders already leverage Pragma. Here is what they think about it.
Since our testnet launch in August of last year, Pragma's price oracle has been a robust and scalable solution to zkLend’s needs. The on-chain price feed and aggregation system has proven reliable and is a valuable asset to our platform.
Brian Fu CEO
We are pleased to partner with the Pragma team and integrating their StarkNet native oracle to our Defi products.
David Garai CEO
The Pragma team has attracted fantastic data partners and Pragma is already one of the leading protocols on StarkNet. I am excited to see them leverage zk-technology to build out their vision of decentralized, transparent and composable data feeds.
