# Solver Trading Fees

## Settlement Costs in Symmio

**Solvers and Market Makers enjoy zero fees.**\
Symmio’s settlement cost structure is designed to encourage the participation of professional market makers and solvers. Solvers and Market Makers do **not** pay settlement fees. This approach mirrors the “Market Maker programs” seen in Order Book DEX environments, where liquid and efficient markets are rewarded by charging makers differently—often zero fees—to encourage tighter spreads and better liquidity for all users.

**User-facing Product-Specific Settlement Costs**\
Settlement costs are not one-size-fits-all. The exact fee structure varies depending on the product type.  Every product category has different settlement costs, read more in each respective category:

**Platform Fees and Affiliate Credits**\
A portion of each platform fee is allocated to the exchange’s affiliate partner—the frontend builder. This means that if you run a frontend interface integrated with Symmio, you can earn a share of the fees generated when traders execute orders through your platform. To learn more about becoming a frontend partner and start building with our toolkit, visit the [Choosing an Exchange](/trader-documentation/choosing-an-exchange.md) section and explore the [Frontend SDK](https://github.com/SYMM-IO/frontend-sdk).

***

**Overview**\
As a B2B-focused solution, Symmio provides a “Derivatives as a Service” model that empowers builders to launch their own decentralized perpetual or derivatives exchanges. Whenever traders execute trades through the Symmio clearing layer, a platform fee is applied. This fee supports the ecosystem, incentivizes liquidity provision, and helps maintain the high-performance clearing infrastructure.
