keystoremetamask
I am very shocked. After a crash on my computer, I lost my Seed Words file to access my MetaMask account. However, I found a Keystore file (UTC or json file), but when I import it into MetaMask I can not find my Ethereum. I'll get another ETH adress and there is no ETH in my wallet.. How is this possible? And how do I get back into my old account without Seed Words, but with UTC keystore file? If this succeeds, it will make me very happy!
Kind regards,
Koen
Thanks for asking, this is a common question but did not have a good public answer. I've updated the MetaMask user FAQ to include a response, and am copying that answer here:
MetaMask does not currently display your token balances, but that doesn't mean you can't manage your tokens with MetaMask!
Since MetaMask allows any website to interact with the blockchain, you can use any token managing UI you like to view and send tokens.
A few popular options are:
Just visit any of these sites with MetaMask installed, and you'll be able to manage your tokens freely.
All you need to do is import the JSON file using mist. Open mist, press Ctrl I and drop your wallet json file into the resulting dialog.
