I have an .dat file from Stratis. And i want to open this wallet on a new computer. Can anyone explain how to do that? The wallet is completly sinc. And i removed the .dat file and put there the old .dat file. But it doesn`t work.
What exactly does not work? You could try to navigate to the folder of your Stratis wallet in a command prompt and then open the stratis executable with the -rescan command behind it, this should do a rescan of the blockchain and calculate the balances and addresses in your wallet.dat file
