If you have ETHEREUM selected as your payment coin please be aware we no longer support withdrawals to contract addresses. You will still be able to withdraw your ETHEREUM funds to an externally owned address (EOA) More details on EOA addresses can be found here
You will see the following error message if you attempt to withdraw to a contract address: ‘Address must be an Externally Owned Address (EOA), not a contract address’. You will need to add an Externally Owned Address via the Wallets page in the console in order to withdraw your ETH funds.
Please make sure you are entering the exact wallet address you wish to send your funds to and double-check for any mistakes.
