Demonstrate the potential of leveraging even minimal on-chain data effectively

Problem Statement

This project shows how easily meaningful insights can be derived from blockchain data, including:TransactionsToken transfersContract deploymentsENS domain actions (registrations, renewals)From this data, the app estimates:Likely user time zones (based on timestamps)Linked or associated walletsJust enter any Ethereum address to reveal insights typically unavailable on standard explorers.

Solution

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}/transactionsToken transfers:https://{chain}.blockscout.com/api/v2/addresses/{address}/token-transfersENS data:Address lookup:https://bens.services.blockscout.com/api/v1/1/addresses:lookupDomain events:https://bens.services.blockscout.com/api/v1/1/domains/{domain}/eventsDomain 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.
