Headless tokenisation.
Full lifecycle. Your UI.

FRACTIONED's API gives developer teams everything they need to embed tokenisation into existing products. No UI constraints. No vendor lock-in on the frontend. Just clean REST endpoints covering the entire token lifecycle — from creation to distribution.
