# Referral

Integrators of Mayan Swap SDK and widget can earn from swaps by setting their wallet address as the referrer.

The default referrer fee rate is **10 bps** ([basis points](https://en.wikipedia.org/wiki/Basis_point)), however as a referrer, you have the flexibility to set your referral fee rate according to your preferences. The referral fee can range from **0 **up to** 50 bps**.

For [WH](/architecture/wh-swap) method you can set your referrer fee [here](https://explorer.mayan.finance/referrer-fee), for [Swift](/architecture/swift) and [MCTP](/architecture/mctp) you can simply pass the `referrerBps` parameter to the SDK or API.

<Info>
  Please check [Mayan SDK](https://github.com/mayan-finance/swap-sdk) and [widget](/integration/swap-widget)to see how you can set your referrer address

*P.S. zero bps makes sense if you want to just track swaps going through your widget or SDK.*
