Preferably these actions are onchain so the CBTs can be dropped automatically to the earners, but they can also be off-chain by allowing the community to give CBTs retroactively based on a performed activity in the real world. Later on, these tokens can be used as a merit-based governance, for reputation, as a community credit score for under-collaterlised loans, or any creative ways the community can think of.\n\nFor this specific example project, with which we were finalists at ETHGlobal Paris, we forked a Safe{Wallet} and added a social layer to it. The purpose was to showcase how you can attach a specific value of CBTs to specific actions inside a Safe, and make a multi-sig more engaging to interact with by adding a Feed/Chat and reputation points to the proposed actions. When a proposal is passed, the proposer receives the reputation points (RP) that are attached to these specific types of proposals. They can range from proposing a new member, to proposing swaps, buying an ENS, or putting the community treasury to generate yield.\n\nSince the creation of the Community-bound tokens a couple of weeks ago, another team built another use-case around it for the Superhack, and we received a lot of interest from web3 communities who want to implement this to measure the engagement of their members, and gamify their communities\n\nHow it's Made:\nWe modified two parameters of the standard ERC-20 token to make it transferable to only a whitelist of addresses that comes, for example, from a Safe.\n\nThe deployed ERC-20 can only be ownable by community members, which in this case can only be added by the Safe multi-sig owner (the Safe itself). The functions mint() and transfer() can only be executed by the members of that community.\n\nWe forked Safe{Wallet} and integrated Push Chat into it. We then used Hardhat to deploy our custom made ERC-20 Community Bound Token to Sepolia, Linea, Gnosis Chain, Mantle, Zetachain and Celo.\n\n", "logoImgData": {}, "bannerImgData": {}, "projectGithub": "TroopFinance", "projectTwitter": "communitybound_"}
