Defined in:
lib/bsv/transaction/fee_models/satoshis_per_kilobyte.rb

Overview

Fee model that charges a configurable number of satoshis per kilobyte.

Uses the transaction’s estimated size (from templates for unsigned inputs, actual size for signed inputs) to compute the fee.

Examples:

model = BSV::Transaction::FeeModels::SatoshisPerKilobyte.new(value: 100)
fee = model.compute_fee(transaction) # => 25 (for a ~250 byte tx)
