Websocket Methods

Subscribe to Real-Time Solana Data via WebSocket

After connecting to the RPC PubSub websocket at ws://<ADDRESS>/:

• Submit subscription requests to the websocket using the methods below

• Multiple subscriptions may be active at once

• Many subscriptions take the optional commitment parameter, defining how finalized a change should be to trigger a notification. For subscriptions, if commitment is unspecified, the default value is finalized.

Subscription Methods

These methods allow clients to subscribe to real-time updates about on-chain events through Solana’s WebSocket-based PubSub system. They're essential for building reactive applications like explorers, dashboards, bots, and monitoring tools.

• accountSubscribe – Subscribes to updates on a specific account’s data. Useful for tracking balance changes or state updates in real time.

• accountUnsubscribe – Cancels an active account subscription to stop receiving updates.

• blockSubscribe – Subscribes to notifications whenever a new block is produced. Ideal for syncing block data or triggering logic based on finalized blocks.

• blockUnsubscribe – Unsubscribes from block updates.

• logsSubscribe – Subscribes to program log outputs (e.g., emitted via msg!() in Solana programs). Helpful for debugging, tracking program activity, or triggering off-chain events.

• logsUnsubscribe – Stops receiving program log updates.

• programSubscribe – Subscribes to changes in all accounts owned by a specific program. Useful for monitoring a protocol’s account activity across the network.

• programUnsubscribe – Unsubscribes from a program update stream.

• signatureSubscribe – Subscribes to status updates for a given transaction signature. Used to monitor whether a specific transaction gets confirmed or fails.

• signatureUnsubscribe – Stops tracking a specific transaction signature.

• slotSubscribe – Subscribes to notifications whenever a new slot is processed. Useful for applications that need to stay in sync with the network clock.

• slotUnsubscribe – Ends the slot subscription.

These real-time methods are vital for building event-driven dApps that respond to Solana state changes as they happen.
