Quick update on this fip. I've spent the past couple weeks improving our observability and stability on the snapchain side so i've only just got back to implementing it. In that time we also added scoping on the message types that a gasless snapchain signer can submit.
Scoping and a sliding TTL will help prevent unauthorized and unintended signer use without compromising UX and devX. We borrowed scoping and sliding TTLs vaguely from OAuth so the semantics and language are already familiar in the web dev community.
