Fees
Exactly which fees a swap or bridge pays and where they go.
| Fee | Who receives it | Where it shows |
|---|---|---|
| Network fee (gas) | The chain's validators | "Network cost" line |
| 0x fee | 0x, as reported in the quote | "0x fee" line |
| Bridge provider fees | The bridge provider | One line per component the API returns |
| Integrator fee | ZK OS | "Integrator fee" line |
Integrator fee#
The ZK OS integrator fee is currently None. It is off by default and only applies when the operator configures both a recipient address and a rate. When enabled, the rate in basis points is shown on every quote and in the confirmation dialog before you trade. For swaps it is taken in the sell token; for bridges it is collected in the sell token on the origin chain.
Slippage is not a fee, but you may receive less than quoted, down to the "Minimum received" amount.
