Description

Build a dApp using an indexer to check the activities of given EVM addresses. Activities are based on smart contract interactions and transactions. For example, a mint() call or approve() call to a contract can be considered an activity. Categorize the activities and build useful scoring systems using the activity data.

If users connect their wallets to the dApp (Metamask or Talisman), you can calculate their scores and add them to a leaderboard.

Interesting scoring systems:

Trader Score 📈: based on how often the users interact with the DEXes and operate token swaps and how much their volumes are

Farmer Score 👨‍🌾: based on how often the users provide liquidity on various DeFi protocols and how much they provided

Degen Score 💰: based on how often the users’ position on lending protocols and CDPs and how high their leverages are

Diamond Hand Score 💎🙌: based on how long in average for users to hold certain tokens

Acceptance Criteria

Implement 2+ scoring systems for on-chain addressesBuild a dApp that allows users to connect their wallets, calculate their scores, and record on the leader boardUsing a data indexer like SubSquid or SubQuery.
