Install with Cosmovisor​

ADVANCED ROUTE

Cosmosvisor is a process manager for Cosmos SDK application binaries that monitors the governance module for incoming chain upgrade proposals. If a proposal is approved, cosmosvisor can automatically download the new binary, stop the current one, switch to the new binary, and restart the node with the new binary.

Download and build binaries​

Clone Zetachain repo and build zetacored v22.0.0​
