# Pragma

> The open infrastructure for oracles

Pragma provides provable data feeds for blockchain applications, leveraging zero-knowledge technology to ensure data is decentralized, transparent, and composable.

Pragma is the leading oracle on Starknet, delivering decentralized, transparent, and composable data feeds for DeFi applications. It offers various product types including price feeds, computational feeds, verifiable random functions, optimistic oracle, and merkle feeds for options data. Using STARK proofs to validate data correctness, Pragma enables developers to build trustless applications with verifiable off-chain data.

## Products

- [Pragma Oracle](https://thegrid.id/profiles/pragma): Pragma Oracle implements decentralized data aggregation through on-chain computation using STARK proofs, enabling verifiable price feeds and market data. The system processes raw data from whitelisted providers while maintaining transparency and 200ms latency for real-time applications. The platform includes verifiable random function capabilities using Curve25519 cryptography for on-chain randomness generation, optimistic oracle functionality for binary outcome validation through dispute mechanisms, computational feeds for volatility and yield curves, merkle-based data verification, and API services for off-chain data access.

Trademarks, logos, and brand names (marked "Special TPIP") are not covered by the ODbL. For ML/AI use: training datasets that substantially extract ODbL data are Derivative Databases and must be shared under ODbL if publicly used; models must be attributed in documentation.

Model 2 - commercial licenses. The Grid Data Service (TGDS) is also available as a commercial license. See [Web Services Terms](https://about.thegrid.id/legal/web-services-terms) for commercial use that is not covered by the open data service.

The following applies to both licensing models.
- All data is provided AS IS with no guarantees of accuracy.
- The Grid does not provide investment, legal, or tax advice, and
