INFINITY_TOKEN global variable mutability to immutable
Content:
I noticed that other contracts use immutable to optimize gas consumption, and the only global variable in the InfinityStaker.sol contract that will change during the deployment phase and not change later is not set to immutable, so I suggest changing the mutability of INFINITY_TOKEN to immutable.
