What it returns

The active ENS names (on BASE also Basenames) linked to one wallet, newest registration first, up to 50 per page: each name, whether it resolves to this wallet, whether this wallet owns it (directly or through the name wrapper), the address it resolves to, its owners, and its registration and expiry times. Anyone can point a name they own at any address, so a name with resolvesHere true and ownedHere false says nothing about who the wallet is — ownedHere is the signal of control. For the one primary name only, use wallet-labels. Keep passing nextCursor back as cursor until it is null. An address with no names answers an empty list.
