SWYPE API Guide: Build Non-Custodial Crypto Swaps Without Exposing Routing Logic

If you’re building a crypto product in 2026, users expect two things at the same time: Fast route execution Clear trust boundaries That combination is exactly where SWYPE is useful. It gives teams a non-custodial routing interface for public swaps, private swaps, and fiat-connected flows, while keeping proprietary route selection internals abstracted.
