Revenue share
We share our fee with you.
Send customers with your referral link. You earn a share of our fee on every order — they see our live rate, you just share a link.
Run private
crypto swaps.
Quote, create, get paid — three signed calls, signed webhooks, one production exchange behind them.
Two ways to earn.
Share our fee on the traffic you send us, or add your own markup through the API. Use either — or both.
Markup
Add your margin on top.
Integrate through the API and add your own margin on top of our rate. We re-quote and sign it; you keep the markup, we keep the base fee.
Three calls,
start to finish.
Get a quote, create the order, watch it settle. Sign the exact bytes you send — we re-quote server-side, so your price always matches ours.
