Network Requirements
Public Ports
ZetaChain nodes communicate over the following ports. Make sure these are open to the public internet.
| Node Type | Port | Protocol |
|---|---|---|
| Full Node and Validator | 26656 | TCP |
| Observer Signer Only | 8123 | TCP |
| Observer Signer Only | 6668 | TCP |
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.
| RPC Type | Port | Protocol |
|---|---|---|
| EVM RPC - HTTP | 8545 | TCP |
| EVM RPC - WSS | 8546 | TCP |
| Cosmos RPC | 1317 | TCP |
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.
