bash
wget -O 0gchaind https://github.com/0glabs/0g-chain/releases/download/v0.5.3/0gchaind-linux-v0.5.3
chmod +x ./0gchaind

Let's stop & move binary to Cosmovisor then start node

bash
sudo systemctl stop 0gchaind
sudo mv ./0gchaind $HOME/.0gchain/cosmovisor/upgrades/v0.5.0/bin/0gchaind
sudo systemctl start 0gchaind

Check version

bash
0gchaind version

Done!
