}

Fields

fee_percent: f32

Fee percentage (e.g., 0.02 for 2%)

reserve_fee_min: Amount

Minimum reserve fee

network: Option<String>

Bitcoin network (mainnet, testnet, signet, regtest)

chain_source_type: Option<String>

Chain source type (“esplora” or “bitcoinrpc”; defaults to “bitcoinrpc”)

esplora_url: Option<String>

Esplora URL (when chain_source_type = “esplora”)

esplora_parallel_requests: usize

Number of parallel Esplora requests during wallet sync.

Public Esplora servers often rate-limit bursty clients, so the default is conservative. Increase only when using a private or higher-limit Esplora server.

bitcoind_rpc_host: Option<String>

Bitcoin RPC host (when chain_source_type = “bitcoinrpc”)

bitcoind_rpc_port: Option<u16>

Bitcoin RPC port

bitcoind_rpc_user: Option<String>

Bitcoin RPC user

bitcoind_rpc_password: Option<String>

Bitcoin RPC password

mnemonic: Option<String>

BIP-39 mnemonic for the BDK wallet

batch_config: BatchConfig

Batch processor configuration

num_confs: u32

Number of confirmations required for incoming payments.

Must be >= 1. A value of 0 is rejected at startup because the confirmation check still requires the transaction to have an on-chain anchor (i.e. 0 would mean “confirmed in any block”, not “accept unconfirmed”). Use 1 for “accept any confirmation”.

min_receive_amount_sat: u64

Minimum receive amount in sats

min_send_amount_sat: u64

Minimum send amount in sats

sync_interval_secs: u64

Wallet sync interval in seconds
