CommunityCounter is a reaction to other counter contracts that enforce strict rules on who has permission to modify a global counter. The crypto space tenets are based on sovereignty, privacy, and community. Instead, many in our industry are losing the plot and are building systems that are becoming centralized, permissioned, and controlled by the few.

Thankfully, there are those of us who will fight to keep the original promises alive. CommunityCounter is one of those projects. A public good that provides a global counter that anyone can increment. The gas costs are socialized and individuals do not need to expose their underlying wallet to modify the counter: they can do so anonymously if they wish.

How to use

Using ERC-4337, users do not need to sign a transaction to modify the counter. Instead users can send a UserOperation (an ERC-4337 transaction) with the increment or decrement method as the callData value. As long as the community has funded the CommunityContract with enough ETH to cover the costs, then the counter will be updated. No metadata about the user who sent the UserOperation will be exposed publicly.

To keep the contract topped up with enough ETH, community members can call the depositTo() method on the EntryPoint contract. Users who wish to top up can send a transaction directly (using their wallet), or fund a wallet privately to send the deposit transaction. By topping up the contract, you are helping to ensure that the counter stays private and free for members who might need it.
