GMX has introduced builder fees for third-party developers operating on the Solana network, allowing them to collect additional revenue from trading orders. This update enables developers to publish custom fee rates onchain that are added to standard trading costs for eligible position orders.
Why it matters
This mechanism provides a new monetization channel for developers building on Solana by allowing them to capture a portion of the value from trading activity. For operators, it marks a shift toward developer-centric revenue models within decentralized execution environments.
Developers can now levy fees on eligible position orders at rates like 0.01%, which results in a 10 cent charge on a $1,000 position increase. While market, limit, and stop-loss orders are included in this fee structure, liquidations and swaps remain excluded.
The players
GMX
A decentralized exchange platform that provides perpetual trading services across various blockchain networks.
Solana
A high-performance blockchain network that serves as the infrastructure for decentralized financial applications.
The details
Developers publish their specific fee rates directly onchain, which traders then acknowledge by signing orders at that rate. The builder fees operate as an add-on to standard trading fees, with collected amounts settling into a claimable treasury for the developer. All orders routed through this system continue to utilize existing liquidity pools and oracle pricing mechanisms to ensure consistent execution.

Market Landscape
This development integrates new monetization tools directly into the Solana network liquidity pool execution framework. It marks a transition from standard platform fees to a tiered model that incentivizes third-party development through direct revenue capture.
Operators currently deploying solutions on Solana should evaluate whether implementing builder fees aligns with their user acquisition strategy or creates excessive friction. Carefully track trading volume changes to ensure that additional fee layers do not drive users toward lower-cost alternative protocols.
The takeaway
The addition of builder fees provides a new way to capture value from trading activity, but it requires careful balancing of developer revenue against user cost sensitivity. Monitor order flow metrics closely to determine how these added charges affect total platform adoption in the coming quarter.
