How to add funds to a Governor treasury?

Support Contracts
1

I am working on creating a DAO using the ERC20Votes and Governor contracts. I created the governor using the wizard, however I don't see any function for adding funds to the Governor treasury. I imagine this is necessary so that the token holders can vote for proposals that allocate funds from the treasury. Is this function already implemented or do I have to implement it myself?

Your Governor is using a timelock. The funds should be transferred to the timelock contract. No special functionality is necessary, you can just transfer ETH or ERC20 into the timelock address.

You should generally try this out with a small amount of funds first to make sure you can use them later!
