Legacy contracts

Legacy contracts remain integrated so existing positions stay spendable.

Sale

Sale v4, v3 and v2
Pre-batch sale escrow

Rent

Rent v5, v4, v3, v2 and v1
Bulk Rent v6 and older
Rental vault versions matching each listing

Lend

Lend v1 is deprecated and read-only.
Do not create new Lend positions.
Do not reintroduce automatic renewals without an allowlist and prepaid credit.

Rules

Legacy contracts keep their legacy fee behavior.
New listings use the current version.
A contract upgrade requires new addresses and a documented migration.
