+## Price Feeds
+
+Smart contracts often act in real-time on data such as prices of assets. This is especially true in [DeFi](https://chain.link/use-cases/defi).
+
+For example, lending and borrowing platforms like [Aave](https://aave.com) utilize Data Feeds to assess collateral value accurately, while perpetual platforms such as [GMX](https://gmx.io) rely on these feeds to validate offchain data and ensure that each deposit or withdrawal executes at the correct market value.
+
+- To learn how to use Price Feeds, see the [Price Feeds](/data-feeds/price-feeds) documentation.
+- See the [Data Feeds Contract Addresses](/data-feeds/price-feeds/addresses) page for a list of available networks and addresses.
+
+## Tokenized Equity Feeds
+
+Chainlink Tokenized Equity Feeds provide continuous 24/5 pricing for tokenized representations of US equities and ETFs. These feeds deliver the calculated primary market price of the token as determined by the issuer's pricing methodology.
+
+- To learn more, see the [Tokenized Equity Feeds](/data-feeds/tokenized-equity-feeds) documentation.
+- See the [Provider Catalog](/data-feeds/tokenized-equity-feeds/providers) for a list of supported providers.
+
+## SmartData Feeds
+
+Chainlink SmartData is a suite of onchain data offerings designed to unlock the utility, accessibility, and reliability of tokenized real-world assets (RWAs). By providing secure minting assurances alongside essential real-world data such as reserves, Net Asset Value (NAV), and Assets Under Management (AUM) data, the SmartData suite embeds security and enriches data into tokenized RWA offerings.
+
+- To learn more about the broader SmartData suite, see the [SmartData](/data-feeds/smartdata) documentation.
+- See the [SmartData Contract Addresses](/data-feeds/smartdata/addresses) page for a list of available networks and addresses.
+
+### Multiple-Variable Response (MVR) Feeds
+
+The SmartData suite includes [Multiple-Variable Response (MVR) Feeds](/data-feeds/mvr-feeds), which bundle multiple data points of various types into a single onchain update. Unlike traditional feeds that provide only one numeric value, MVR feeds can return multiple values of different types (both numeric and non-numeric) in a single transaction.
+
+- To learn more about MVR Feeds, see the [Multiple-Variable Response (MVR) Feeds](/data-feeds/mvr-feeds) documentation.
+- See the [SmartData Contract Addresses](/data-feeds/smartdata/addresses) page for a list of available networks and addresses. Use the _Show Multiple-Variable Response (MVR) feeds_ checkbox to filter the list.
+
+## Smart Value Recapture (SVR) Feeds
+
+Smart Value Recapture (SVR) Feeds introduce a mechanism to recapture Oracle Extractable Value (OEV), a form of MEV associated with oracle updates, often observed during liquidations.
+
+- To learn more, see the [Smart Value Recapture (SVR) Feeds](/data-feeds/svr-feeds) documentation.
+- Find SVR-enabled addresses on the [Price Feed Addresses](/data-feeds/price-feeds/addresses) page by filtering for SVR feeds.
+
+## Rate and Volatility Feeds
+
+Several feeds provide interest rate curve data, APY data, and realized asset price volatility.
+
+- To learn more, see the [Rate and Volatility Feeds](/data-feeds/rates-feeds) documentation.
+- See the [Rate and Volatility Contract Addresses](/data-feeds/rates-feeds/addresses) page for a list of available networks and addresses.
+
+## L2 sequencer uptime feeds
+
+L2 sequencer feeds track the last known status of the sequencer on an L2 network at a given point in time. This helps you prevent mass liquidations by providing a grace period to allow customers to react to these events.
+
+To learn how to use L2 sequencer uptime feeds, see the [L2 Sequencer Uptime Feeds](/data-feeds/l2-sequencer-feeds) documentation.
+
+## 24/7 Extended-Hours Data Feeds
+
+Some assets only trade during specific market hours: precious metals and forex markets close on weekends and holidays, and some currencies trade mainly during local hours or are subject to capital controls. To support applications that need continuous price data anyway, Chainlink offers 24/7 extended-hours feeds for certain assets in these categories.
+
+To learn more, see the [24/7 Extended-Hours Data Feeds](/data-feeds/24-7-extended-hours-data-feeds) documentation.
+
+## Self-managed feeds
+
+Some networks publish Data Feed–style proxy contracts where **onchain updates are written by the chain or a third-party operator** (for example using a CRE workflow that reads [Chainlink Data Streams](/data-streams)), rather than through Chainlink Labs–managed decentralized oracle networks. **Chainlink Labs does not operate, monitor, or list addresses** for these deployments in official feed catalogs.
+
+For responsibilities, monitoring scope, and how to obtain contract addresses, see [Self-Managed Feeds](/data-feeds/self-managed-feeds).
