agd init --chain-id $chainName <node_name>
```

6. **Download genesis.**

```
curl https://main.agoric.net/genesis.json > $HOME/.agoric/config/genesis.json
```

7. **Add seeds and peers to `config.toml`.**

```
peers=$(jq '.peers | join(",")' < chain.json)
seeds=$(jq '.seeds | join(",")' < chain.json)
sed -i.bak -e "s/^seeds *=.*/seeds = $seeds/; s/^persistent_peers *=.*/persistent_peers = $peers/" $HOME/.agoric/config/config.toml
```

8. **Set up minimum gas price.**

9. **Set up pruning (optional).**

```
pruning="custom"
pruning_keep_recent="100"

pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.agoric/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.agoric/config/app.toml
```

10. **Create service file.**

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

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

[Install]
WantedBy=multi-user.target
