| Pyth delivers real-time market data published first-party by exchanges, market makers, and banks: 3,500+ feeds across crypto, equities, ETFs, FX, commodities, and fixed income via [Pyth Pro](https://docs.pyth.network/price-feeds/pro), plus Pyth Indices for 24/7 pricing of assets whose underlying markets follow exchange hours. | ||

| Pyth on Stellar uses a pull model. Applications subscribe to signed price updates off-chain (WebSocket or REST), then verify them on-chain through a cross-contract call to Pyth's deployed verifier contract using the [`pyth-lazer-stellar-sdk`](https://docs.rs/pyth-lazer-stellar-sdk) crate. On-chain verification is permissionless; receiving the data feeds requires a [subscription](https://app.pyth.com) (a 14-day free trial is available). The Stellar contracts were audited by [Zellic](https://github.com/pyth-network/audit-reports/blob/main/2026_09_01/pyth_pro_stellar_zellic_audit_report.pdf). |

What
Adds Pyth to the Oracle Providers page. Pyth Pro and Pyth Indices are live on Stellar mainnet (public launch September 8, 2026), but this page currently doesn't list them.
The new section follows the existing page format (provider description, integration link, deployed-contracts table) and covers:
pyth-lazer-stellar-sdk)Verification
The contract addresses match Pyth's contract-addresses docs, and both deployments were functionally tested via Stellar RPC simulation (trusted-signer config confirmed;
verify_updateaccepts a live signed payload and rejects a tampered one).Note for reviewers
RedStone (live on Stellar since March 2026) is also missing from this page — happy to add it in this PR or a follow-up if maintainers prefer.
