c4ed config keyring-backend file
c4ed config node tcp://localhost:26657
  • Configure cosmovisor: 
    cd $HOME
export DAEMON_NAME=c4ed
export DAEMON_HOME=$HOME/.c4e-chain
cosmovisor init $(which c4ed)
  • Download genesis and addrbook file: 
    wget -O $HOME/.c4e-chain/config/genesis.json "https://snapshot-at-1.genznodes.dev/c4e/genesis.json"
wget -O $HOME/.c4e-chain/config/addrbook.json "https://snapshot-at-1.genznodes.dev/c4e/addrbook.json"
  • Using our node snapshot / statesync ( if needed )

  • Launch nodes: 
    sudo systemctl daemon-reload
sudo systemctl enable c4ed
sudo systemctl start c4ed
journalctl -fu c4ed -o cat

    • Troubleshooting

    1. Error: binary not present

  • If you see logs like this, pay attention to [UPGRADE_NAME] :
    Error: binary not present
stat $HOME/.c4e-chain/cosmovisor/upgrades/[UPGRADE_NAME]/bin/c4ed: no such file or directory"
c4ed.service: Main process exited, code=exited, status=1/FAILURE
c4ed.service: Failed with result 'exit-code'.
  • Fix with:
    Make sure you change [UPGRADE_NAME] according to your logs
    export DAEMON_NAME=c4ed
export DAEMON_HOME=$HOME/.c4e-chain
cosmovisor add-upgrade [UPGRADE_NAME] $(which c4ed)
  • Check node logs:
    journalctl -fu c4ed -o cat
