You (and apps) can use this port to check execution node status, query execution-layer chain data, and even submit You can use curl to make multiple RPC requests (batch requests) over HTTP at the same time. Do I need to enable something or what ip should I use to connect to it? I am using web3. configTemplate master --geth Geth node ports are not default, as the Kava EVM will use default JSON-RPC ^ Note how we can just use our IP’s alias as the Hostname. I'm puzzled but I guess I'll just start digging through the code. Skip to main content. JSON-RPC is provided on multiple transports. Therefore if now we trying to send some command to shell or even geth they do not return needed response since shell is waiting The token should be somewhere in the execution client’s data directory (at least this is how geth works). The RPC connection must be authenticated using a jwtsecret file. I don’t cover security in this article, but you can read more about that here (securing your GETH node’s RPC ports). I'm running the geth node with A Tron full node is a participant in the Tron network that stores the complete blockchain data on a local hard drive.
