KyberSwap fees: distinguish the swap from the product

There is no useful single answer to “What is the KyberSwap fee?” until the product and route are identified. A same-chain aggregator swap, a cross-chain transfer and a liquidity-management action can have different charges.

Start with the fee's owner

The aggregator documentation allows integrating applications to customize fees. A third-party app using KyberSwap infrastructure may therefore add terms that differ from the provider's own interface.

The cross-chain guide separately identifies a platform fee and any underlying protocol fee. It shows those details at route review. A statement about one of those charges cannot establish that the other is absent.

Do not import a pool's fee schedule

If a search result describes an older pool product, it may explain what liquidity providers charge within that pool. That is a different scope from the current aggregator service. Record the product title, publication context and date before using a numerical rate in a comparison.

For a specific trade, inspect the returned output and the disclosed charges. Determine whether a charge is already deducted from the output or is a separate payment. The network fee shown by the wallet is another line item with a different recipient.

Surplus is another allocation to understand

The API documentation discusses treatment of favorable execution differences. That should be evaluated separately from a fixed fee: a policy governing better-than-estimated execution does not apply identically to every trade.

A practical fee question

Ask, “For this input, output, network and selected route, what amount reaches my wallet and which additional costs remain?” This is answerable from the current quote and wallet confirmation. A blanket assertion that the whole KyberSwap product family is free or charges a historical percentage is not.
