Astar Bounty #14 Submission

Project

Astar Identity Scoring System

Open-source React + TypeScript dApp that ranks EVM addresses on Astar using public Blockscout activity.

Repository

Local project path:

• /root/astar-identity-scoring

What it does

• Connects an injected EVM wallet such as MetaMask or Talisman
• Accepts any EVM address for manual scoring
• Loads public example addresses from Astar activity
• Scores addresses using three systems:
  • Trader
  • Farmer
  • Diamond hand
• Shows a live leaderboard saved in local storage
• Explains the metrics behind each score

How it matches the bounty

The bounty requested:

• an indexer-based Astar EVM activity checker
• 2+ scoring systems
• wallet connection
• leaderboard display

This project uses the public Astar Blockscout API as the indexer source and turns the data into a scoring dashboard.

Data source

• https://astar.blockscout.com/api

Used endpoints:

• module=account&action=txlist
• module=account&action=tokentx

Scoring

• Trader
  • contract calls
  • approvals
  • unique counterparties
  • gas spent
• Farmer
  • token transfer volume
  • unique token contracts
  • active days
• Diamond hand
  • estimated average holding duration
  • estimated longest holding duration
  • currently held contracts

Validation

Passed locally:

• npm run lint
• npm run test
• npm run build

Notes

• Leaderboard data is stored locally in the browser.
• Public sample loading is best-effort and can fall back to manual address analysis.
• The UI is responsive and designed for desktop and mobile review.
