We have released support for Box Verified Enterprise (BVE) EIDs in Box Sign.
Previously, all signing links generated by Box Sign were on the app.box.com subdomain and not on the subdomain configured via the BVE EID.
Now, Box Sign takes into account the BVE settings and generates signing links on the configured subdomain (if EID is BVE) or on app.box.com (if EID is not BVE).
If a customer on a Box Verified Enterprise EID blocks app.box.com as part of their network settings, their internal users now can access the signing links just like they access shared links today.
More info on BVE here.
