Once the exchange reopens its withdrawal and deposit services, users will be able to utilize the new deposit address.\r\n\r\nKuCoin also declared that it would keep supporting ERC-20 QuarkChain token deposits to the early ERC20 address. The QuarkChain tokens held on the KuCoin exchange will be replaced automatically with the MainNet ones.
