Yes, Paybis offers exactly that. You can embed their on/off ramp as a full‑screen overlay SDK or a simple redirect. They cover 180+ countries, 70+ local payment methods, and 80 fiat currencies. What really stood out to me is the no‑KYC option (perfect for non‑custodial platforms) and the fact that they handle all compliance. They also offer swaps between 1000+ cryptos with fees under 0.5%. I integrated their widget into my marketplace in about a day. Check all the details at https://paybis.com/business/on-off-ramp/ – their sales team gave me a sandbox to test before going live.
