Enable indexer** sed -i "s/^indexer *=.*/indexer = \"kv\"/" $HOME/.evmosd/config/config.toml ### **Create a Service file** sudo tee /etc/systemd/system/ogd.service > /dev/null << EOF [Unit] Description=OG Node After=network.target [Service] User=$USER Type=simple ExecStart=$(which evmosd) start --home $HOME/.evmosd Restart=on-failure LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF ### **Start the Node** sudo systemctl daemon-reload && sudo systemctl enable ogd && sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat ### **Download Snapshot** wget https://rpc-zero-gravity-testnet.nofena99.org/latest_snapshot.tar.lz4 Stop the node sudo systemctl stop ogd Backup priv\_validator\_state.json cp $HOME/.evmosd/data/priv_validator_state.json $HOME/.evmosd/priv_validator_state.json.backup Reset DB evmosd tendermint unsafe-reset-all --home $HOME/.evmosd --keep-addr-book Extract files fromt the arvhive lz4 -d -c ./latest_snapshot.tar.lz4 | tar -xf - -C $HOME/.evmosd Move priv\_validator\_state.json back mv $HOME/.evmosd/priv_validator_state.json.backup $HOME/.evmosd/data/priv_validator_state.json Restart the node sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat ### **Create a Wallet for Your Validator** evmosd keys add $WALLET_NAME !Note: save seed pharse. If you don't save the seed pharse you can't get it back if you want to recover wallet use command: evmosd keys add $WALLET_NAME --recover ### **Extract the HEX Address to Request Some Tokens from the Faucet** echo "0x$(evmosd debug addr $(evmosd keys show $WALLET_NAME -a) | grep hex | awk '{print $3}')" You can extract the private keys in address above, use command: evmosd keys unsafe-export-eth-key $WALLET_NAME You can add account with private keys in metamask, account use faucet token if you want. Save private keys add to metamask to faucet token ### **Faucet Token** [https://faucet.0g.ai/](https://faucet.0g.ai/) Note: The faucet gives you _100000000000000000aevmos_. To make the validator join the active set you need at least _1000000000000000000aevmos_ (_10 times more_) ### **Check Wallet Balances** evmosd q bank balances $(evmosd keys show $WALLET_NAME -a) ### Check if Node Synced evmosd status | jq .SyncInfo.catching_up If your node synced (`"catching_up"=False`) you can create validator ### **Create a Validator** evmosd tx staking create-validator \ --amount=10000000000000000aevmos \ --pubkey=$(evmosd tendermint show-validator) \ --moniker=$MONIKER \ --chain-id=$CHAIN_ID \ --commission-rate=0.05 \ --commission-max-rate=0.10 \ --commission-max-change-rate=0.01 \ --min-self-delegation=1 \ --from=$WALLET_NAME \ --gas=500000 --gas-prices=99999aevmos \ -y You can check your Validator status here. Please allow some time for your validator to be added to the 0G Validator list. ### **Backup Validator Keys** cp $HOME/.evmosd/data/priv_validator_state.json $HOME/.evmosd/priv_validator_state.json.backup ### **Check After Validator Created** evmosd q staking validator $(evmosd keys show $WALLET_NAME --bech val -a) --- *Originally published on [Nofena99](https://paragraph.com/@nofena99/0g-node-setup-guide)*
