```

**Create service**&#x20;

```
tee $HOME/celestia-appd.service > /dev/null <<EOF

EOF
sudo mv $HOME/celestia-appd.service /etc/systemd/system/

sudo systemctl daemon-reload
```

```
celestia-appd keys add wallet
```

\
Check addr Validator<br>

```
 celestia-appd keys show yourwallet --bech val -a
```

**Snapshot**

```
sudo systemctl stop celestia-appd 

cp $HOME/.celestia-app/data/priv_validator_state.json $HOME/.celestia-app/priv_validator_state.json.backup 

rm -rf $HOME/.celestia-app/data $HOME/.celestia-app/wasmPath

mv $HOME/.celestia-app/priv_validator_state.json.backup $HOME/.celestia-app/data/priv_validator_state.json 

sudo systemctl restart celestia-appd && sudo journalctl -u celestia-appd -f
```

Check sync\ <br>

```
celestia-appd status 2>&1 | jq .SyncInfo.catching_up
```

If it is False => Create Validator

```
