The problem Karma Calculator solves

• Identify users who believe in on chain transactions
• Identify good users who are not dumping tokens every now an then
• Find users fit for your protocol/usecase by tweaking the weights used to calculate Karma
• For example, if you are a AMM, identify wallets who have already interacted with Uniswap, Sushiswap, 1inch etc
• Identify L2 users, ENS owners,
• Identify potential sponsors by giving higher rank to public goods supporters(Gitcoin funders)

Challenges I ran into

• Third party APIs for getting transaction data
• No central repository for all the router contracts for various protocols. We need a DefiPulse but for protocol contracts not just metrics
