drowt, we understand that maintenance works can be an inconvenience: no-one wants to wait to make a transaction. However, please understand that we wouldn't start the maintenance if it were possible to perform certain procedures without affecting our users. Blockchain is a volatile environment, and we're updating our wallets regularly to make sure our users stay safe.
By the way, the maintenance on the ZCash wallet was completed, you can retry your transaction, there shouldn't be any issues with it. Sorry for taking so long!
I just donated some ETH to the Bread crowdsale, after that I find that freewallet are using a service wallet to make transactions. Could you help me with this problem? Based on the etherscan result, the Bread tokens have been distributed to your service wallet already. Can I provide another ERC20 address and please send those tokens to me?
