RPC method
eth_subscribe on Zora
Not available on SwiftNodes
Everything below was measured on 2026-10-13 by calling eth_subscribe on Zora through the same endpoint customers use, and is re-measured weekly.
What eth_subscribe does
Opens a subscription over WebSocket: newHeads pushes each new block header, logs pushes matching events, and newPendingTransactions pushes mempool transaction hashes where the node exposes them. It replaces polling, and it only works over WebSocket, not HTTP.
On Zora
newHeads did not work on Zora in our probe. Poll eth_blockNumber instead.
