Pyth Network is shutting down Conflux eSpace support on July 31, 2026. Adds a new oracle page documenting the Conflux-maintained drop-in replacement (conflux-fans/oracle-contracts): verified mainnet/testnet proxy addresses, supported price feed IDs (same IDs as Pyth for major assets), migration steps from Pyth's pull model, a consumer contract example, and trust/limitation notes (1h cadence, role-based updaters, UUPS upgradeability). Adds a sunset warning to the existing Pyth tutorial linking to the migration page. Contract addresses verified on-chain: proxies and implementations have code, and the mainnet oracle serves a current CFX/USD price. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

| A **Conflux-maintained, Pyth-compatible price oracle** is deployed as a drop-in read-side replacement. Existing integrators can migrate by pointing at a new contract address — the read functions and price feed IDs are unchanged for the major assets. | ||
| ::: | ||
|
|
||
| The replacement oracle is an on-chain price feed service maintained for the Conflux community, with source code at [conflux-fans/oracle-contracts](https://github.com/conflux-fans/oracle-contracts). Its read API is fully compatible with the [Pyth SDK Solidity interface](https://github.com/pyth-network/pyth-sdk-solidity) (`getPriceUnsafe`, `getPriceNoOlderThan`, `getEmaPriceUnsafe`, `getEmaPriceNoOlderThan`), returning the same `PythStructs.Price` type. |

There was a problem hiding this comment.
getEmaPirceUnsafe and getEmaPriceNoOlderThan are not supported now, calling this method will result revert
Verified every read function against the deployed mainnet and testnet contracts. Corrections: - EMA prices are not available. Mainnet reverts with "EmaPrice not supported"; testnet does not revert and returns the spot price, so EMA-reading code passes on testnet and fails on mainnet. - getPrice(id) is getPriceNoOlderThan(id, getValidTimePeriod()), and that window (3600s) equals the publish cadence, so passing 3600 to getPriceNoOlderThan reproduces the same behaviour. - getValidTimePeriod() constrains only the deprecated getPrice / getEmaPrice, not getPriceNoOlderThan. - getPriceUnsafe applies no staleness check; publishTime is the only indication of age. - Reads revert with PriceFeedNotFound() / StalePrice() rather than returning sentinel values. - updatePriceFeeds / updatePriceFeedsIfNecessary / getUpdateFee are absent from the bytecode, so leftover calls revert. - USDT0 parity is a redemption property of the LayerZero OFT design, not a guarantee that the two trade identically. Also drops suitability and staleness-bound recommendations in favour of stating the mechanism, leaving those judgements to integrators. Co-Authored-By: Claude <noreply@anthropic.com>
