Type Alias: TokenTransferFeeConfig

TokenTransferFeeConfig = { destBytesOverhead: number; destGasOverhead: number; fastFinalityFeeUSDCents: number; fastFinalityTransferFeeBps: number; finalityFeeUSDCents: number; finalityTransferFeeBps: number; isEnabled: boolean; }

Defined in: chain.ts:242

Token transfer fee configuration returned by TokenPool v2.0 contracts.

Remarks

Contains two fee dimensions per finality mode (default vs custom/FTF):

• A flat USD surcharge (in cents) added to the CCIP fee via FeeQuoter
• A BPS rate deducted directly from the transferred token amount by the pool

"Default" fields apply when finality is 0 or 'finalized' (standard finality). "Custom" fields apply when finality is a block depth \> 0 (Faster-Than-Finality).
