# Fees Aggregator Fees are split into two categories: Protocol Fee and Integrator Fee. No protcol fee is taken on trades performed through the Aftermath Smart-Order Router. The Integrator Fee allows dApps which utilize the Aftermath Smart-Order Router to specify their own fee if they wish. Users should refer to their respective documentation to determine if an Integrator Fee has been applied. Aftermath Aggregator allows setting an optional platform fee, configurable per swap via the API.\ • If no fee is configured for a given swap, no fee is applied, and users receive the full output.\ • When a fee is applied, Aftermath retains 2.5% of whatever platform fee is set, as part of its protocol overhead. Trades peformed on Aftermath.finance do not charge an Integrator Fee. There is no fee for performing a swap on Aftermath.finance or AF.lol through the Aftermath Smart-Order Router. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
