Orbit users have slowly started to reach out to the platform on social media, asking for transactions to be canceled and to receive funds back. One user said their transaction is still pending validation. 

Can you please cancel the pending transactions/bridging attempts ? I didn't know that you guys got hacked and i just want my tokens back.
The transaction hasn't been yet confirmed by a validator. Please.

Another user posted that users are confused and “on edge” waiting for validators, saying that no one is answering requests.

Please answer the question when you will connect validators. Moreover, most transactions for completely different tokens are now expected to take 24 hours. Could you pleasee nable validators already? People are confused and on edge. Nobody is answering. Comments were closed.
