Network Requirements

Public Ports

ZetaChain nodes communicate over the following ports. Make sure these are open to the public internet.

Node TypePortProtocol
Full Node and Validator26656TCP
Observer Signer Only8123TCP
Observer Signer Only6668TCP

Additionally, Observer Signers must allow communication between zetacored and zetaclientd on port 9090 but this port should not be publicly accessible.

RPC/API/Archive Nodes

If you want to access RPC/API services on your node you'll need to make sure the following ports are open.

Operating System

ZetaChain nodes have been developed and tested on x86_64 architecture. Our binary files have been compiled with Ubuntu 22.04 LTS x86_64. This guide assumes you are using Ubuntu 22.04 LTS x86_64. If you are using a different OS you may need to make some adjustments.
