Address Reputation Checker

WHAT IT DOES

Address Reputation Checker is a read-only security tool that evaluates the reputation of any Ethereum wallet address using on-chain data and community-sourced flag lists. It checks addresses against known scam, phishing, and sanctioned lists, analyzes transaction history, token balances, contract interactions, transaction frequency, first and last transaction timestamps, unique counterparties, and unique contracts interacted with. The tool computes a reputation score from 0 to 100, with corresponding reputation levels (Good, Fair, Poor, Flagged), and displays a detailed breakdown of risk factors that contributed to the score.

HOW TO USE

Enter any wallet address and click Check Reputation. The tool scans recent transaction history using Transfer events as a proxy for activity, checks the address against built-in flag lists, and analyzes behavioral patterns. Results include the reputation score, reputation level, any flags detected (scam, phishing, sanctioned), ETH balance, transaction count, unique counterparties, unique contracts interacted with, first and last transaction blocks, and a detailed list of risk factors. All data is presented in a clean, informative dashboard.

ADAPTIVE LOG-CHUNKING WITH BACKOFF

Public RPC providers enforce wildly different eth_getLogs block range limits — some allow 10,000 blocks, others cap at 1,000, and many reject requests that exceed their internal buffer. Instead of guessing a safe range and failing on the first rejection, this checker walks backwards from the latest block in dynamically sized chunks. When a request is rejected, the chunk size is halved and retried immediately. This guarantees that the scan completes on any provider without overwhelming the endpoint, and without giving up after a single refusal. The tool separately scans incoming and outgoing Transfer events to build a comprehensive view of the address's activity patterns and counterparty relationships.

WHAT IT CANNOT SEE

This tool cannot detect off-chain reputation or social activity. It cannot identify private key compromises. It cannot access centralized exchange AML/KYC data. It cannot detect future malicious intent. It cannot analyze cross-chain activity. It cannot verify the identity or intent behind any address. It relies on community-sourced flag lists which may be incomplete or contain false positives. The reputation score is based solely on on-chain patterns and flag lists, and does not constitute financial or security advice. It cannot detect phishing attempts, wallet drainers, or compromised dApps that have not yet been flagged by community sources.

PLEASE NOTE

EVM ONLY. Supports all Ethereum-compatible networks (Ethereum, Goerli, Sepolia, Optimism, Arbitrum, Polygon, and others). No Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. This tool is intended for informational purposes only and should not be used as the sole basis for security decisions. Always conduct your own research and use multiple independent sources when evaluating address reputation. Flag lists are examples only and may not reflect actual current threats.
