voteSubscribe — Solana WebSocket Method

voteSubscribe sends a notification every time a vote transaction is observed by the validator. Vote transactions are how validators confirm slots.

Important notes

• voteSubscribe is an unstable method. It may not be available on all providers.
• Vote transactions account for the majority of all Solana transactions. This subscription generates extremely high message volume — hundreds of messages per second.
• This method is intended for validators and infrastructure monitoring, not general application use.

FAQ

How much data does voteSubscribe produce? Validators submit votes every slot (~400ms), and there are ~1,500+ active validators. Expect hundreds to thousands of messages per second. This is not suitable for browser-based applications.

Can I filter votes by validator? No. voteSubscribe has no filter parameters. To track a specific validator, filter client-side by votePubkey.

Why would I use this instead of getVoteAccounts? getVoteAccounts returns a snapshot of vote account state. voteSubscribe gives real-time visibility into vote activity as it happens — useful for monitoring consensus health and validator behavior.
