Integrators can configure trading fees for users accessing Lighter through their interface, within global limits set by Lighter. #### Integrator Fees Integrators may configure fees for both spot and perpetual markets. Global limits set by Lighter: * Perpetual markets: up to 10 bps * Spot markets: up to 1% * Minimum fee increment: 0.01 bps #### User Approval Before fees can be applied, the user must sign a message approving the integrator’s fee configuration. This approval: * authorizes the integrator to charge the configured fees * includes an expiry period (if integrator decides to include one) * can be revoked by the user at any time The approval has signature requirements depend on whether the integrator and user share the same L1 account. * Different L1 accounts: L1 approval + L2 confirmation * Same L1 account: L2 confirmation only #### Begin your Integration: API Docs: Python SDK:
