Intersect Publishes Pyth Pro Access Details for Cardano Projects

Intersect published details on June 17 for Cardano projects seeking access to Pyth Pro, the market data service from Pyth Network. According to the announcement, projects building on Cardano can request a Pyth Pro API key with full access for one year and no usage caps. The onboarding process is handled by the Pyth team.

Intersect Outlines Pyth Pro Access Terms

According to Intersect, the access path is open to projects building on Cardano, including DEX protocols, lending applications, stablecoin systems, synthetic asset platforms, derivatives products and other applications that use market data in smart contract logic.

Projects are asked to contact the Pyth team at genia@dourolabs.xyz with the project name and a short description of what they are building. The Pyth team then issues the API key and provides onboarding support.

Pyth Pro provides real time price feeds that can be used for collateral pricing, reference prices and on chain risk management. Pyth Network says its data is aggregated from institutional publishers, market makers and exchanges. Each price feed includes a confidence interval, giving applications an additional data point around the reported market price.

Cardano Integration Uses a Pull Based Oracle Model

Pyth Pro on Cardano uses a pull based model. An application or its off chain component fetches the latest signed price update through the Pyth Pro websocket or TypeScript SDK, then includes that update in a Cardano transaction. The on chain transaction verifies the signed data before the application smart contract uses it.

Pyth’s Cardano documentation describes the integration through the Aiken library pyth-network/pyth-lazer-cardano. The application contract reads verified update data through the pyth.get_updates function. The documentation states that this function reads the Pyth State UTxO from the transaction reference inputs and the verified update bytes from the redeemer of the Pyth withdraw script.

The transaction must include the Pyth State UTxO as a reference input and a zero lovelace withdrawal from the Pyth withdraw script. The Pyth withdraw script verifies the signature validity of the price update, but it does not automatically enforce freshness. If an application requires a specific validity window, its own contract must check the timestamp_us field.

Pyth Pro Added Through Cardano Critical Integrations Framework

Pyth Pro is part of the wider Cardano Critical Integrations framework. Intersect’s earlier program status report listed Pyth Network pricing oracles among the delivered integrations under CCI V1, alongside infrastructure areas such as stablecoins, analytics and cross chain messaging.

The Critical Integrations program has been administered through Intersect, with strategic direction involving Input Output, Cardano Foundation, EMURGO, Midnight Foundation and Intersect. Within that framework, Pyth Network covers the oracle data layer used by DeFi protocols, RWA applications, stablecoin issuers and other products that require reference prices for collateral, settlement or risk calculations.

Pyth Network previously announced that Pyth Pro was live on Cardano, with Indigo Protocol listed as the first integration. Indigo is a Cardano synthetic asset platform where users can mint and trade synthetic versions of real world assets on chain. The June 17 Intersect announcement adds a published access route for other Cardano teams, giving projects a documented way to request an API key, receive onboarding support and integrate Pyth Pro market data into Cardano smart contracts during the first 12 months. $PYTH appears in this context through the wider Pyth Network ecosystem, while the announcement itself concerns Pyth Pro access for applications building on Cardano. $PYTH remains separate from the technical integration path described for Cardano smart contracts.
