Project Description

This project shows how easily meaningful insights can be derived from blockchain data, including:

  • Transactions
  • Token transfers
  • Contract deployments
  • ENS domain actions (registrations, renewals)

From this data, the app estimates:

  • Likely user time zones (based on timestamps)
  • Linked or associated wallets

Just enter any Ethereum address to reveal insights typically unavailable on standard explorers.

How it's Made

Data is sourced from the Blockscout API:

  • General info:
    https://eth.blockscout.com/api/v2/addresses/{address}

  • Transactions (per chain):
    https://{chain}.blockscout.com/api/v2/addresses/{address}/transactions

  • Token transfers:
    https://{chain}.blockscout.com/api/v2/addresses/{address}/token-transfers

  • ENS data:

    • Address lookup: https://bens.services.blockscout.com/api/v1/1/addresses:lookup
    • Domain events: https://bens.services.blockscout.com/api/v1/1/domains/{domain}/events
    • Domain info: https://bens.services.blockscout.com/api/v1/1/domains/{domain}

Timestamps from user interactions help infer time zones.
Connections between wallets are estimated by weighting interaction patterns.
