Why can’t I see my balances when I unlock my wallet?

This is most likely due to the fact that you are behind a firewall. It is common for the API that is used to display the balance to be blocked by firewalls. You will still be able to send transactions, but you will need to use a blockchain explorer, such as Etherscan, to view your balance.

Why can’t I see the account I have just created in the blockchain explorer (e.g., Etherchain, Etherscan)?

Only active accounts are visible in a blockchain explorer. Once you have transferred some ETH into the account, it should be visible.

How does MyEtherWallet actually work?

I am trying to unlock my wallet but it keeps freezing / hanging.

Sorry you are having trouble. Decrypting the keystore files is an intensive process and takes longer in Javascript. We recommend:

  1. Using Google Chrome.
  2. Clicking “Continue” when you see the unresponsive error alert pop up.
  3. Closing other intensive programs open (e.g., a lot of browser tabs, video games, etc.).

The combination of the above typically eliminates the problem. If it doesn’t, please contact us and include your browser and OS and we can advise from there.

Why am I seeing two different versions of my Ethereum address — one with uppercase letters and one with lowercase letters?
Capitalization simply means the address has a checksum, which will detect input errors. Both addresses refer to the same wallet and are fully functional.

For example, two versions of an Ethereum address are below.

● 0x0430894efd64349c078877E42F1c7c7B838cf108

● 0x0430894efd64349c078877e42f1c7c7b838cf108

The address containing lowercase letters is not checksummed. Mistyping a letter or number in this address can result in the loss of ETH. On the other hand, the upper case checksummed version of the address will detect typos and inform you of an invalid address.

For this reason, MyEtherWallet warns you when your address is not checksummed. Remember to double check the address to prevent any issues.

If you are sending ETH to one of your own wallets, you can save the checksummed address via the “View Wallet Info” page and copy the address displayed there.
