Гаманець для Zeebu

What is Zeebu (ZBU)?

Zeebu belongs to an unusual corner of crypto: wholesale telecom settlement. Carriers that exchange voice and data traffic invoice each other constantly across borders, and those invoices normally crawl through correspondent banks. The Zeebu platform settles them on-chain instead, and ZBU is the token that circulates inside that system, issued to participating carriers in connection with the volume they settle through it.

For someone simply holding ZBU, the operational detail that matters is that it exists as an ERC-20 on several chains at once. Each deployment is its own contract with its own balance, and a transfer only ever moves within one of them. Sending ZBU to a counterparty who is watching a different chain means the tokens are not lost but are not where they are being looked for either, and recovering the situation depends entirely on who controls that address.

Fees follow the chain, not the token. On one network the transaction is paid for in ETH, on another in BNB, and ZBU itself never covers its own transfer cost, so a balance with no gas coin beside it is stuck.

Because this is a token people actually move rather than only store, Tangem keeps the relevant gas coin in the same wallet as the ZBU and signs each payment by a tap of the card on the phone, with no cable, no charging and no desktop involved. Settling from a card you carry suits a token built around settling invoices.
