ChainStream API
Stream blockchain events in real-time without developing a Geyser plugin

Introducing ChainStream API

Subscribe to blockchain events using a RPC PubSub WebSocket

ChainStream APIs are a way to stream Solana transaction, slot, and block updates directly from the validator. This set of APIs is still in a Beta, please contact Syndica Support for access.

ChainStream APIs

The ChainStream APIs allow you to stream transaction, slot, and block updates in real time using a RPC PubSub WebSocket. Why does this matter? For some mission critical applications, having the latest blocks, slot updates (whether they're processed, rooted or confirmed) and real time processed commitment level transactions streamed to your application is super important.

Transaction Notifications

Receive a notification anytime a transaction is processed by the validator. These transactions are at the “processed” commitment level - even before it has been confirmed by the cluster.

Block Notifications

Receive a notification every time a new block is processed by the validator. Use this to trigger any processes that kick-off with the presence of a new block.

Slot Updates

Receive a notification anytime a slot is updated by the validator. Use this to trigger processes that start depending on a slot’s status (processed, confirmed or rooted).
