Tokenizing a real-world asset is mostly a document problem, less a chain problem. We put private aircraft deals on Ethereum, and the token accumulated signed documents and deal state from listing to closing. Minting was the easy part. Modelling who signs what, in what order, and what happens when one party stalls took the rest of the project. The chain ended up as the audit trail rather than the product.
We think it is worth checking where your deal state really sits.
