[Install]
WantedBy=multi-user.target
EOF
```

```bash
sudo systemctl daemon-reload
```

## Download snapshot for fast sync

backup priv\_validator\_state.json

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

download and extract files from archive

```bash
curl https://testnet-files.itrocket.net/celestia/snap_celestia.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.celestia-app
```

move priv\_validator\_state.json back

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

Start the node and check logs

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

Check sync status. false = synced

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

## Create or recover wallet

> Dont forget to save mnemonic

create wallet

```bash
celestia-appd keys add $WALLET
```

recover wallet

```bash
celestia-appd keys add $WALLET --recover
```

set your wallet var

```bash
WALLET_ADDRESS=$(celestia-appd keys show $WALLET -a)
VALOPER_ADDRESS=$(celestia-appd keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="$WALLET_ADDRESS >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="$VALOPER_ADDRESS >> $HOME/.bash_profile
source $HOME/.bash_profile
```

## Request tokens from the faucet 🆓

> Request tokens from discord "faucet" channel <https://discord.com/invite/YsnTPcSfWQ>

--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(celestia-appd tendermint show-validator) \
--moniker "moniker" \
--identity "" \
--website "" \
--details "" \
--chain-id mocha-4 \
--gas auto --gas-adjustment 1.5 --gas-prices 0.005utia \
-y
```

## Useful commands ⚙️

Sync status
