A design note on how we built NFT business renting — because the architecture is the product.
The obvious way to build NFT rental is a new smart contract: escrow the token, encode the lease on-chain, redeploy every time the business model changes. We deliberately did not do that.
On AIBIZ, the NFT holds exactly one thing: lifetime ownership. Everything rental lives on the rail — the server-side registry every consumer asks:
- A lease ENDS by its timestamp. No cron job, no scheduler that dies silently. The residency question simply stops answering with the renter when the term passes, and the chip is home.
- While rented, the OWNER is locked out of execution — only the renter may run the chip. Enforced at the invoke gate.
- Guest keys fail CLOSED: every use re-checks the live lease. Expiry kills access mid-request, not at the next cleanup.
- Per-feature scopes, identity NFTs, card payments, top-ups — all shipped in days, with zero contract redeploys.
When rental demand proves out, a contract-level version (ERC-4907 style) can make leases provable without the rail — as an addition, never a prerequisite. Iterate the business model on the rail; harden what stabilizes into the chain.
