There is no way to change the STADIUM_ADDRESS
if it is compromised
I understand the STADIUM_ADDRESS is immutable but this is a possible vulnerability if the this address is compromised in any way, specially in the case of the STADIUM_ADDRESS becomes blacklisted by any token, this will revert every attempt to send it the commission from any contest.
If the STADIUM_ADDRESS is compromised in any way the prize will be locked forever.
Manual
add a function controlled by an owner that can change the STADIUM_ADDRESS in case something goes wrong. maybe also add a timelock if necessary.
