The error “Account does not exist” indicates that your TRX account has not been activated. You can activate your TRX wallet by depositing TRX into the wallet.
If you want to make transactions after the activation, please make sure there is enough available TRX in your wallet to provide bandwidth and energy. Otherwise the transfer will fail or you will get the error “Not enough TRX or bandwidth for transfer”.
Therefore, it is recommended to transfer 50~100 TRX to your wallet, then you can successfully make transactions after your TRX wallet is activated.
