Cronos ID wallet

What is Cronos ID (CROID)?

A name instead of an address

Cronos ID is the naming layer for the Cronos chain. Instead of handing someone a forty-two character string, you register a readable name that resolves to your address, and the same identity is meant to carry notifications and messaging addressed to that name. Registration is a subscription rather than a purchase: the name is held for a chosen period and has to be renewed, and the fee can be paid in CRO or in CROID.

CROID is that system's own token, used for paying registration and renewal and for governance of the service. Two details matter when you hold it. The first is gas: CROID is a token on Cronos, and every transfer of it, every renewal, every registration is paid for in CRO, so an empty CRO balance freezes the whole thing no matter how much CROID sits in the wallet. The second is that the domain itself is not the token. The name you register is a separate on-chain item tied to the address that holds it, so if you ever move your CROID somewhere else, the name stays with the address that registered it.

Renewals are small, occasional transactions rather than a one-off event, and Tangem handles them by tap: the phone builds the transaction, the card signs it against the back of the phone, and the CRO you need for gas sits in the same wallet next to the CROID. No cable, no charging, which is what you want from a wallet you reach for a couple of times a year to keep a name alive.
