# Pragma > The open infrastructure for oracles Pragma is an oracle infrastructure provider for blockchain applications. It delivers verifiable price and data feeds using zero-knowledge proofs for decentralized applications on multiple networks. Pragma is an oracle infrastructure provider that delivers decentralized, verifiable data feeds for onchain applications. It supplies price feeds, computational feeds, verifiable random functions, an optimistic oracle, and merkle feeds for options data. The infrastructure is aimed at developers building decentralized finance applications that require trustless access to off-chain data. The platform addresses the reliance on centralized, opaque data sources in onchain applications by pushing data directly onchain from whitelisted market makers and exchanges, then validating its correctness using zero-knowledge proofs. This removes the need for a trusted intermediary between raw data and the smart contracts consuming it, while keeping the computation auditable end to end. Pragma operates primarily on Starknet and has extended its oracle design to additional zero-knowledge rollup environments. Its product suite spans price feeds, computational feeds such as realized volatility, and randomness services, alongside developer tools for integrating or building new feeds. Lending protocols, decentralized exchanges, and other onchain financial applications rely on Pragma for collateral pricing and market data. The infrastructure is used by application developers and data providers who publish or consume verifiable feeds across the ecosystem. - Type: Company - Sector: Data & Analytics - Status: Active - Founded: 2022-03-01 - Profile: https://thegrid.id/profiles/pragma ## Products - [Pragma Oracle](https://thegrid.id/profiles/pragma): Pragma Oracle is an oracle protocol on Starknet that delivers verifiable price feeds and market data to smart contracts. It aggregates signed data submitted on-chain by multiple publishers, computing medians and other aggregation methods entirely on-chain so the process remains transparent and auditable. Developers and DeFi protocols use it to price collateral, set liquidation thresholds, and access derived computational feeds such as time-weighted averages, volatility, and yield curves. The product also exposes an off-chain API and websocket service for applications that need aggregated price and market data outside of on-chain calls, while earlier features such as a verifiable random function, an optimistic oracle, and merkle-based feeds have been deprecated in favor of the current feed set. (Oracle, Live, Main Product) - [Pragma Miden Oracle](https://thegrid.id/profiles/pragma): Pragma Miden Oracle is an oracle implementation built for the Miden zero-knowledge rollup, delivering verifiable median price data to applications on that network. It uses an actor-model architecture in which publishers write price entries into their own accounts through locally proven self-transactions, and the oracle account aggregates prices across registered publishers on demand using foreign procedure invocation. This design avoids off-chain intermediaries or a trusted aggregator, letting consuming applications verify correctness through the network's proof system. The product serves developers building applications on Miden who need transparent, provable pricing data.
