How to start using Mitilena Wallet

  • You need to understand that there is always a blockchain address and this address will have its own private key (password).
  • You need to randomly generate your address and private key here.
  • Go to Mitilena wallet, click “Add wallet” and enter the address in the blockchain. You do not need to enter your private key.
  • Your new address and current balance will appear in the list of your wallets.

You need to find out what you have:

  • Private key to your blockchain address.
  • Seed phrase (12-16 words) from your addresses.
  • You have neither the first nor the second, but only funds in some wallet or exchange.

Let's analyze each case separately.

So, the first case:
This is the easiest option.

  • You need to randomly generate your address and private key here.
  • Go to Mitilena wallet, click “Add wallet” and enter the address in the blockchain. You do not need to enter your private key.
  • Your new address and current balance will appear in the list of your wallets.
  • When you need to send funds, you will only enter your private key at that point.

The second case:

Different wallets and exchanges may inadvertently generate addresses from seed phrases differently. We advise you to create new wallets with us, and transfer funds there from the old wallet. However, you can try to save the seed phrase:

  • Go to Mitilena wallet, click “Add wallet” and enter the address in the blockchain. You do not need to enter your private key.
  • Your new address and current balance will appear in the list of your wallets.
  • When you need to send funds, the last step is to ask for a private key or mnemonic (seed phrase, 12-16 words). We have a standardized extraction of private keys from the seed phrase, the first 50 addresses are checked. Most likely, the algorithm will be able to extract the private key from your seed phrase. We advise you to check on a small amount.

The third case:

  • You need to understand that there is always a blockchain address and this address will have its own private key (password).
  • You need to randomly generate your address and private key here.
  • Go to Mitilena wallet, click “Add wallet” and enter the address in the blockchain. You do not need to enter your private key.
  • Your new address and current balance will appear in the list of your wallets.
  • Go to your old wallet or exchange and withdraw the funds to your new address in the Mitilena wallet.
