Logs subscribe

Stream matching transaction logs

Solana

Logs subscribe listens for transaction log notifications. Use an address mention filter to watch a narrower stream while learning.

Try it step by step#

  1. Choose mentions in Filter and enter an address involved in activity you want to observe.
  2. Connect a node that records the received signature and logs, then start listening.
  3. Inspect err as well as logs when a notification arrives. Stop the run after the observation.

What to expect#

The result includes signature, logs, err, and context.slot. A log notification can describe a failed transaction; receiving logs alone does not establish success.

Things to check#

  • all and allWithVotes can produce much larger streams than a mention filter.
  • Logs are program messages. Their wording is not a stable substitute for a decoded event format.
  • Use the dedicated Pump or Raydium watchers when you need those integrations’ parsed event fields.

Network setup: This node uses solana. See connections for RPC setup and Test mode for network selection.
