Struct DevnetConfig 

pub struct DevnetConfig {
    pub node_count: usize,
    pub base_port: u16,
    pub bootstrap_count: usize,
    pub data_dir: PathBuf,
    pub spawn_delay: Duration,
    pub stabilization_timeout: Duration,
    pub node_startup_timeout: Duration,
    pub enable_node_logging: bool,
    pub cleanup_data_dir: bool,
    pub evm_network: Option<Network>,
}

Configuration for the devnet.

Each configuration is automatically isolated with unique ports and data directories to prevent collisions when running multiple devnets.

Fields

node_count: usize

Number of nodes to spawn (default: 25).

base_port: u16

Base port for node allocation (0 = auto).

bootstrap_count: usize

Number of bootstrap nodes (first N nodes, default: 3).

data_dir: PathBuf

Root directory for devnet data.

spawn_delay: Duration

Delay between node spawns (default: 200ms).

stabilization_timeout: Duration

Timeout for network stabilization (default: 120s).

node_startup_timeout: Duration

Timeout for single node startup (default: 30s).

enable_node_logging: bool

Enable verbose logging for devnet nodes.

cleanup_data_dir: bool

Whether to remove the data directory on shutdown.

evm_network: Option<Network>

Optional EVM network for payment verification. When Some, nodes will use this network (e.g. Anvil testnet) for on-chain verification. Defaults to Arbitrum One when None.
