1. Use of addrSet variable in HomeFi.sol

The addrSet variable in HomeFi.sol, does not look to have any significant use other than checking if the address is already set.
This can be also achieved by checking for already set addresses such as projectFactoryInstance or communityContract or even checking the length of wrappedToken[].
The addrSet variable can be safely removed with small code modification.
Code:

2. tokenCurrent1-3 can an array

In HomeFi.sol, three separate variables are defined for tokenCurrent(1-3). These variables are primarily used as indexes and it seems the number of currencies is always 3. In this case, instead of defining 3 separate variables, one array of length 3 can be defined to store all three currencies. This will save some storage gas.
Additionally, these 3 variables can be completely removed and directly referenced when populating the wrappedToken map at line 148
This will make the code a little smaller and much more readable.

Code:

3. Remove unused code:

The below code is never used and can be safely removed to save some gas

Code:
https://github.com/code-423n4/2022-08-rigor/blob/main/contracts/Community.sol#L910-918
https://github.com/code-423n4/2022-08-rigor/blob/main/contracts/HomeFi.sol#L314-322

4 bool parameter for delegateContractor can be removed

Code:
https://github.com/code-423n4/2022-08-rigor/blob/main/contracts/delegateContractor.sol#L148

The function delegateContractor(bool _bool) take bool parameter. However, this parameter can be removed as I am assuming when the function is called, the contractDelegated will either be true or false and that can be determined by evaluating the existing value of contractDelegated.
The code can be changed to contractDelegated = !contractDelegated;

Thx for the findings
3. It is used for meta transaction and we need to override as it is present in both ContextUpgradeable and ERC2771ContextUpgradeable
4. then maybe a more suitable name would be toggleContractorDelegation
