AFAIK, Curve25519 is about the PFS/key-agreement.
Ed25519 is about authentication of the end-points, and depends upon what's
in the certificates (if any are used) to validate the end points.
CoAP-EST does not say anything actually about authentication; i.e. how we
get the Secure Transport. It's out of scope for this document.
(But, in scope for draft-ietf-6tisch-dtsecure-zerotouch-join )
