A rede é TokenMint Chain e não TokenMint Testnet.

Егор Андреев (ID: 0000002e70e6485b) Voted 1 ★ - Updated 11/04/2022 Самый глупый кошелек. Создаю пароль и ни один даже сложный критериям не соответствует, набрал абракадабру с множеством повторяющихся символов и сразу все ОК. Мнемонику скопировать нельзя, а если скриншотишь, то снова пароль и новая мнемоническая фраза, которую надо скопировать. Записывать на листочек при такой глупой безопасности бред. Никому не советую данный кошелек - он просто ужасен.
