#### Create a service

```bash
sudo tee /etc/systemd/system/stchaind.service > /dev/null <<EOF
[Unit]
Description=stchaind Daemon
After=network-online.target
[Service]
User=$USER
ExecStart=$(which stchaind) start
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF
sudo systemctl daemon-reload
sudo systemctl enable stchaind
```

#### Initialize the node

```bash
# Set node configuration
stchaind config chain-id stratos-1
stchaind config keyring-backend file

# Add seeds
sed -i -e "s|^seeds *=.*|seeds = \"cdbd7ce27584e699d9b9e6d72a1551666c750e4d@35.86.41.142:26656,ce225e67f7a383b50c91aeb902a86dd3ecb70d65@34.84.212.13:26656\"|" $HOME/.stchaind/config/config.toml

# Set minimum gas price
sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"1000000000wei\"|" $HOME/.stchaind/config/app.toml

# Set pruning
sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \

```

#### Snapshot (Nodestake.top❤)

```bash
SNAP_NAME=$(curl -s https://ss.stratos.nodestake.top/ | egrep -o ">20.*\.tar.lz4" | tr -d ">")
curl -o - -L https://ss.stratos.nodestake.top/${SNAP_NAME}  | lz4 -c -d - | tar -x -C $HOME/.stchaind
```

#### Start service and check the logs

```bash
sudo systemctl start stchaind && sudo journalctl -u stchaind -f --no-hostname -o cat
```
