echo "PEERS=\"$PEERS\""

# Update the persistent_peers in the config.toml file
sed -i -e "s|^seeds *=.*|seeds = \"$SEEDS\"|; s|^persistent_peers *=.*|persistent_peers = \"$PEERS\"|" $HOME/.mantrachain/config/config.toml
```

#### create service file

```
sudo tee /etc/systemd/system/mantrachaind.service > /dev/null <<EOF
[Unit]
Description=mantrachaind
After=network-online.target

[Service]
User=$USER
ExecStart=$(which mantrachaind) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

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

#### enable and start service

```
sudo systemctl daemon-reload
sudo systemctl enable mantrachaind
sudo systemctl restart mantrachaind && sudo journalctl -fu mantrachaind -o cat
```

#### Snapshot

#### Stop the service and reset the data <a href="#stop-the-service-and-reset-the-data" id="stop-the-service-and-reset-the-data"></a>

```
sudo systemctl stop mantrachaind
cp $HOME/.mantrachain/data/priv_validator_state.json $HOME/.mantrachain/priv_validator_state.json.backup
rm -rf $HOME/.mantrachain/data
```

#### Download latest snapshot <a href="#download-latest-snapshot" id="download-latest-snapshot"></a>

```
curl -L https://snapshots.coinhunterstr.com/mainnet/mantra/snapshot_latest.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.mantrachain
mv $HOME/.mantrachain/priv_validator_state.json.backup $HOME/.mantrachain/data/priv_validator_state.json
```

#### Restart the service and check the log <a href="#restart-the-service-and-check-the-log" id="restart-the-service-and-check-the-log"></a>

```
sudo systemctl restart mantrachaind && sudo journalctl -u mantrachaind -f --no-hostname -o cat
```

## Auto Installation

```
bash <(wget -qO- https://raw.githubusercontent.com/CoinHuntersTR/props/refs/heads/main/AutoInstall/MantraMainnet.sh)
```

### Sync Node

> Node ağ ile eşleşmiş olması gerekiyor. Bunun için `mantrachaind status 2>&1 | jq` komutunu çalıştırdığınızda `false` çıktısı vermesi gerekir. `True` çıktı alırsanız aşağıdaki adımlara devam etmeyin.

### Run a Validator

```
cd $HOME
```

> İlk önce Pubkeyimizi alıyoruz.

```
mantrachaind comet show-validator
```

`{"@type":"/cosmos.crypto.ed25519.PubKey","key":"0LuMdRNJpWGiH+b+................"}` buna benzer bir çıktı alacaksınız.

> Sonrasında validator json dosyası açıyoruz.

> Aşağıdaki dosyayı kendinize göre düzenlemeyi unutmayın. Validator ismi, site linkleri vs.

```
cat << EOF > ~/validator.json
{   
    "pubkey":{"@type":"/cosmos.crypto.ed25519.PubKey","key":"BVTxen+wn6ZgBPUqsgdFDonZ3cr2r+eoYRfF8sTx6kQ="},
    "amount": "10000uom",
    "moniker": "",
    "identity": "",
    "website": "",
    "security": "",
    "details": " Coin Hunters Community ",
    "commission-rate": "0.1",
    "commission-max-rate": "0.2",
    "commission-max-change-rate": "0.01",
    "min-self-delegation": "1"
}
EOF
```

> terminale yapıştırdıktan sonra, CTRL X Y enter ile çıkıyoruz.
>
> Şimdi tekrardan node restart atalım

```
sudo systemctl restart mantrachaind && sudo journalctl -u mantrachaind -f
```

> Şimdi aşağıdaki komutu çalıştırıyoruz. `wallet` yerine kendi cüzdan isminizi yazmayı unutmayın. Terminale cüzdan kurmak için `Useful Commands` bölümüne bakabilirsiniz.

```
mantrachaind tx staking create-validator ~/validator.json --from wallet --gas="auto" --gas-adjustment 2 --gas-prices="0.01uom"
```
