Protocol Fee Model (3% Basis Points)

WAproxy applies a fixed protocol fee defined in basis points (BPS).

Default configuration:
FEE_BPS = 300
= 3%

The protocol fee is calculated as:

protocol_fee = amount_sat × 300 / 10000
receiver_gets = amount_sat - protocol_fee

The fee is deducted from amount_sat, not from the wallet balance. Network fees remain external and are deducted separately by the blockchain layer.

Example:

amount_sat = 20000
protocol_fee = 600
receiver_gets = 19400

This model ensures transparent accounting and deterministic fee application. The protocol does not dynamically change fee rates during execution and does not depend on market conditions.

Execution requires:

wallet_balance >= amount_sat + safety_margin

The protocol fee does not block execution. It is applied consistently across supported coins using the same integer-based logic.

WAproxy applies execution fees deterministically. It does not perform pricing or valuation.
