Source-based practical guide
Configure the plugin on a Solana validator
Enable the gRPC plugin on a validator and check its startup logs.
Before you start
- A Solana validator
- A plugin build whose Solana version matches the validator client version
Steps
Copy and edit the example JSON configuration for the validator.
Add a startup argument such as
--geyser-plugin-config geyser.json.Restart the validator.
Check logs for
Starting GeyserPluginService from config filesorgeyser_grpc_plugin_server::server.
