Refer to this list of common errors and solutions.

  1. ‘Invalid Address’

    • MEW only supports Ethereum-related crypto transactions.

    • If you’re trying to send a token that has launched mainnet, you will likely need to send this crypto to an Ethereum address at an exchange like Binance to make the swap to mainnet.

  2. ‘Not Checksummed’

    • The checksum version of your address is the version that includes both capital and lowercase letters, for accuracy.

      The address itself is not different.

    • You can find this version by searching your address on

  3. ‘Out of Gas’ or ‘Insufficient funds’

    • All transactions on the Ethereum blockchain require ETH for the fuel to make transactions happen.

    • None of this fee comes to us but goes to the remote miners working to keep the blockchain secure and progressing.

  4. Unintelligible Error / Other

    • Please reach out to us with as much information as possible.
