slotsUpdatesSubscribe RPC Method

As of May 1, 2026, this WebSocket method is billed based on metered data usage: 0.1 MB = 15 API credits. Learn more about WebSocket billing.

The Solana Kit example uses createSolanaRpcSubscriptions_UNSTABLE because the Kit API for slot update subscriptions is currently experimental and the implementation may change. The slotsUpdatesSubscribe method itself is fully supported by the Quicknode WebSocket API.
