You can tune fuegod behavior at startup by passing flags on the command line. There is no separate config file — all options are provided as arguments each time you launch the daemon. This page covers the most useful flags for network binding, RPC access, peer management, and data storage.
Network and RPC flags
These flags control how the daemon listens for peer connections and exposes its RPC interface.
| Flag | Default | Description |
|---|
--p2p-bind-port <port> | 10808 | UDP/TCP port for peer-to-peer connections. Open this port in your firewall to allow inbound peers. |
--p2p-external-port <port> | — | Advertise a different external P2P port (useful behind NAT or port forwarding). |
--rpc-bind-ip <ip> | 127.0.0.1 | IP address the RPC server listens on. Change to 0.0.0.0 only if you intend to serve remote clients. |
--rpc-bind-port <port> | 18180 | TCP port for the HTTP RPC interface used by wallets and tools. |
--restricted-rpc | off | Limit the RPC server to read-only, safe methods. Recommended when exposing RPC beyond localhost. |
--enable-cors <domain> | — | Add a Access-Control-Allow-Origin header for the specified domain, enabling browser-based RPC clients. |
Do not bind --rpc-bind-ip to 0.0.0.0 without also enabling --restricted-rpc. Unrestricted public RPC access allows anyone to trigger mining, roll back the chain, or query sensitive pool data on your node.
Logging
| Flag | Default | Description |
|---|
--log-level <0-4> | 2 | Controls log verbosity. 0 is nearly silent; 4 (trace) prints everything. Level 2 is suitable for most day-to-day use. You can also change this at runtime with the set_log console command. |
Data directory
| Flag | Default | Description |
|---|
--data-dir <path> | Platform default | Directory where the daemon stores blockchain data, peer state, and pool state. Useful for running multiple nodes or storing data on a separate volume. |
| File | Description |
|---|
blocks.dat | Raw blockchain block data |
blockindexes.dat | Index mapping block hashes to positions in blocks.dat |
poolstate.bin | Persistent mempool (unconfirmed transaction pool) state |
p2pstate.bin | Peer connection state, including known peer addresses |
Peer connection flags
| Flag | Description |
|---|
--add-peer <IP:port> | Connect to a specific peer at startup in addition to seed nodes. |
--add-exclusive-node <IP:port> | Connect only to this peer. The daemon skips seed nodes and the peer discovery process entirely. Useful for private or local testing setups. |
--seed-node <IP:port> | Use a custom seed node instead of (or in addition to) the hardcoded ones. |
Remote node / fee flags
| Flag | Description |
|---|
--fee-address <XFG address> | Set a fee address for remote node usage. Wallets connecting to your node as a remote node can be charged a small fee that goes to this address. |
Example: public RPC node
To run a node that serves RPC to remote clients on a non-default port with restricted access:
./fuegod \
--rpc-bind-ip 0.0.0.0 \
--rpc-bind-port 18180 \
--restricted-rpc \
--enable-cors "*" \
--fee-address fireYourXFGAddressHere \
--log-level 2
Example: private node with custom data directory
./fuegod \
--data-dir /mnt/storage/fuego-data \
--p2p-bind-port 10808 \
--rpc-bind-port 18180 \
--log-level 1
