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.
