Documents, contracts and keys with signature
Original documents and keys move between offices, notaries, tenants and lawyers with a signature or OTP at handoff.
- Legal ops
- property managers
- conveyancers
- HR onboarding tools

Some things still have to physically move: wet-ink contracts, passports for verification, keys to a flat. Couriers take a day and give a tracking number, not a name.
