Getting Fee Info

​

Background

This doc describes functionality in Skip Go for accessing standardized information about the various fees that a user can incur while swapping or transferring. Common fees include:

• Affiliate fees (e.g. fees you charge the user for swapping on your frontend)
• Bridge and relayer fees
• Smart Relayer fees
• Gas fees

​

Understanding incurred fees from all sources: estimated_fees

estimated_fees in the response of /route and /msgs_direct provides a Fee array where each entry gives information about a particular fee.

Each Fee object in the array will have the following attributes:

• fee_type: Enum giving the kind of fee — SMART_RELAY , SWAP , BRIDGE, RELAY , GAS
• bridge_id : If the fee is a relayer fee (RELAY) or a bridge fee (BRIDGE), this gives the ID of the bridge charging the fee (or the bridge where the relayer is providing a service)
• amount : The amount of the fee (expressed in the token the fee will be charged in)
• usd_amount: Estimated USD value of the fee
• origin_asset : An Asset object containing useful metadata for displaying and identifying the token in which the fee is denominated
• chain_id : Chain ID where the fee will be collected
• denom : Denom of the token in which the fee is denominated
• tx_index: The zero-indexed identifier of the transaction where the user will incur this fee (For multi-transaction routes, fees may be incurred after the first transaction)
• operation_index: The zero-indexed entry in the operations array where the user will incur this fee
