Struct PaymentConfig 

pub struct PaymentConfig {
    pub cache_capacity: usize,
    pub rewards_address: Option<String>,
    pub evm_network: EvmNetworkConfig,
    pub metrics_port: u16,
}

Payment verification configuration.

All new data requires EVM payment on Arbitrum — there is no way to disable payment verification. The cache stores previously verified payments to avoid redundant on-chain lookups.

Fields

cache_capacity: usize

Cache capacity for verified XorNames.

rewards_address: Option<String>

EVM wallet address for receiving payments (e.g., “0x…”). If not set, the node will not be able to receive payments.

evm_network: EvmNetworkConfig

EVM network for payment processing.

metrics_port: u16

Metrics port for Prometheus scraping. Set to 0 to disable metrics endpoint.
