+## Switchboard 
+
+[Switchboard](https://switchboard.xyz) is the fastest, most customizable, and *only* permissionless oracle protocol. The decentralized Switchboard oracle network enables developers to bring any off-chain or cross-chain data onto Aptos through verifiable, ultra-low-latency feeds. 
+With its flexible design and high-throughput architecture, Switchboard is a perfect match for Aptos’ high-speed environment and its focus on accessibility and efficiency.
+
+### Switchboard Features
+
+- Fully permissionless feed creation via the [Feed Builder](https://explorer.switchboardlabs.xyz/feed-builder): deploy custom oracles in minutes
+- [Aggregator](https://docs.switchboard.xyz/product-documentation/aggregator): access multiple oracle sources (like the others on this page) in a single transaction.
+- [Data Feed Variables](https://docs.switchboard.xyz/product-documentation/data-feeds/designing-feeds/data-feed-variable-overrides): bring API-gated or confidential data on-chain without exposing API keys
+- Customizable feeds: adjust feed parameters (confidence intervals, deviation thresholds, and more) to your dapp’s needs
+- [Decentralized oracle network](https://docs.switchboard.xyz/switchboard-protocol/re-staking) secured by globally distributed validator set.
+- [Verifiable Randomness](https://docs.switchboard.xyz/product-documentation/randomness): generate secure, verifiable random numbers for games, lotteries, and more. 
+- Supports any data type: prices, prediction markets, sports, weather, RWAs, etc
+- x402 compatibility: Switchboard is the only x402-compatible oracle. Build more efficient dapps with pay-as-you-go data from any source.
