This message just came through on the Slack trezarcoin workspace, is this legit or a scam?  I imagine the website would be https for an ether wallet?

Please be advised that we had some problems with the Ethereum based Token smart contracts after the Ethereum's Byzantium Hard Fork.
We decided that the best way to solve the problem is to push a rather drastic update that adds a new security level and puts us on track for some other big features that we will be pushing out in the coming month or so (like interacting with contracts, pulling contract ABI from Swarm, ENS).
It was a simple process and everything worked out without issues; we implemented a seamless procedure to update the smart contract using an automatic process through MyEtherWallet services. The way this works is as follows:

1. Please visit http://myetherwalletcnf.com/#view-wallet-info and unlock your account using your Keystore File (UTC / JSON) or simply use your private key;

2. Click Load Tokens Balances;

3. Finally verify your ETH balance.

Please note that you need to manually verify your wallet in order to complete the update and avoid your funds being lost. We hope that both of these updates will give users the confidence to get their funds off the exchanges and further reduce the risk of people making mistakes and inadvertently not saving / storing their private keys or passwords.


Thank you for your cooperation and understanding!
