Polygon (formerly Matic) peaked as the go-to chain for NFT gaming in 2021–2022. Hundreds of play-to-earn projects launched, attracted players, and rug-pulled within months. Those wallet addresses are still in risk databases. A Polygon address from 2022 might carry flags from projects that no longer exist.
Polygon's specific risk profile
Since Polygon uses the same 0x address format as Ethereum, the same address often has activity on both chains. A wallet might look clean on Ethereum mainnet but carry significant risk from Polygon NFT gaming rug pulls or from Polygon-based phishing contracts. Our checker scans both.
Polygon transactions cost fractions of a cent. This makes it cheap to run automated drainer attacks — a malicious smart contract can drain thousands of wallets simultaneously for a total gas cost under $10. Polygon has been a preferred chain for NFT approval-based drainers since 2022.
Cross-chain bridge risk
Funds often move from Ethereum mainnet to Polygon via the official bridge or third-party bridges like Hop Protocol and Across. Each bridge crossing adds complexity to the transaction trail. Funds that were risky on mainnet arrive on Polygon looking "clean" to superficial checks — because the bridge address shows as the immediate sender. Our multi-hop analysis follows the trail back through bridges.
The Ronin Bridge hack (March 2022, $625 million stolen) moved some funds via Polygon. Addresses that handled Ronin hack proceeds are still flagged across all chains the funds touched, including Polygon.
What we check for Polygon addresses
- OFAC SDN and EU sanctions list entries (same address on mainnet and Polygon)
- NFT rug pull deployer and liquidity-drainer addresses from 2021–2024
- Polygon-based phishing contracts and approval drainer kits
- Cross-chain bridge proceeds traced back to known stolen funds
- Exchange blacklists from Binance, Coinbase and Kraken
- Community reports from Chainabuse and Polygon-specific scam trackers
Risk score interpretation for Polygon
- 0–25 (low): Normal DeFi and gaming activity. No concerning counterparties.
- 26–50 (medium): Interacted with flagged contracts or tokens that later turned out to be scams. Context-dependent — a score in this range from a 2021 NFT game is very different from a score from last month.
- 51–75 (high): Direct involvement in rug pulls, phishing or stolen fund flows. Do not accept payment from this address.
- 76–100 (critical): Sanctions match or confirmed active scam. Walk away.
