I want to contribute at ICO but i had a serious problem with this project.
The problem is here:
How to make a back up of my wallet? without back up wallet the project is failed.
If no answer the project is failed.
Why wouldn't there be a way to backup wallet. The browser mining is BETA and the NIM tokens are ERC20 ethereum tokens. Why is this even a question?
Someone said if put F12 there is private key,but how to import?
Betanet is just a demo of our Blockchain we will create wallet apps, cold storage wallets and an entire Ecosystem of applications.
We are adding a import/export tool. For now you can export your private key opening your console (yes, with F12) and introducing: Nimiq.get().wallet.keyPair.toBase64();
This is explained in our API documentation
