# WebSockets

Use WoC Sockets to stream chain stats, mempool transactions, block headers, and more! The [V2 API](/core-products/whatsonchain/websockets/woc-sockets-v2-beta.md) is available in Beta, and the V1 is deprecated.

If your application needs customized/filtered events via WebSockets, please let us know in the [WoC devs Telegram channel.](https://t.me/joinchat/FfE6-EjZhoTHwhDhZH6F-w)
