Fee Tiers

Platform-level configurable schedules assigned to merchants. Stored in fee_tiers (no instance_id — platform-global).

interface FeeConfig {
  creation_fee_pct: number;           // e.g. 2.0
  creation_fee_flat: number;          // e.g. 0.25 USDC
  creation_fee_min: number;           // e.g. 0.25 USDC
  claim_fee_pct: number;              // e.g. 0.0
  claim_fee_flat: number;             // e.g. 0.0
  changelly_markup_pct: number;       // e.g. 0.5
  bridge_developer_fee_pct: number;   // e.g. 1.0
  // Planned additions for distribution:
  rebate_pct: number;                 // e.g. 1.5
  rebate_volume_tiers: VolumeTier[];  // [{threshold_usdc: 50000, rebate_pct: 2.0}]
  rebate_settlement_delay_days: number; // e.g. 7
}

Fee tiers are managed by the platform admin via the System tab (AdminFeeTiersTab).
