デベロッパの回答 、 Hi, You do not need to set up the "Delta Account" to run on multiple devices. https://support.delta.app/en/articles/1462016-how-can-i-sync-two-multiple-devicesThis link can show you how to do it without needing the Delta Account. If any issues you can reach out to us at Settings in Delta - Support - Contact Support. - RE
デベロッパの回答 、 Hi, You can press the + button to add wallets. However if you think Delta is a real exchange or wallet itself, this is not correct. You cannot buy, sell or hold assets on Delta, we just track. You can head to Settings in Delta - Support - Contact Support for more information. - RE
