A personal link. A code to the phone. And it is signed.
The deal is run as a ladder rather than as an email chain: purchase offer, the technical specification required under the Sale (Apartments) Law, contract, and then a signing order in which each party signs in turn. The link opens on the signer's phone, a one-time code proves it is them, and the signature is captured. What comes out the other side is a signing certificate carrying the document hash — and the signed document is the proof this is a transaction system and not a listings board.
