Unlocking a wallet index exchange is a risky thing right? Do we need to move tokens to temp MEW and then access that wallet?
Do you mean unblock wallet through IDEX exchange?
In my opinion, you should to use MEW to transfer token to a temporary address to unblock on IDEX exchange instead of use the primary address to do this.
I do not know the future IDEX exchange will be a scam exchange or not, although until today I did not see any problem related about lose money after used IDEX exchange
