How this service works
The flagship: balance, token holdings, recent activity, USD portfolio value, and an OFAC sanctions-list check for a wallet, in one call -- across Ethereum, Base, Arbitrum, Optimism, Polygon, Bitcoin, and Solana. Cheaper and simpler than calling wallet-balance + token-holdings + address-activity separately. Sanctions screening only (not a general scam detector) -- an honest, narrower claim, not a vague safety score.
Output
Returns a JSON object containing: chain name, address, sanctioned boolean, native token symbol and balance, list of token holdings with symbol/balance/USD value/contract address, recent transaction activity with direction/counterparty/value/timestamp, total portfolio USD value, and availability flags indicating whether activity and token data were retrievable.
Example use cases
Pre-payment counterparty due diligence
“Before I send funds, scan this Ethereum address 0xabc123...def for sanctions flags, recent activity, and total portfolio value so I know if it looks legitimate.”
DeFi portfolio snapshot
“Give me a full breakdown of my Solana wallet DRpbCBMxVnDK7maPLmKd9tXD4HkGBEnqUGDXJB3fkqz — show all token balances, their USD values, and any recent incoming or outgoing transactions.”
Compliance audit on a flagged address
“Run a wallet scan on Base address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e and tell me if it's sanctioned, what tokens it holds, and how active it's been recently.”
Technical details
Endpoint
POSThttps://chainsscope.duckdns.org/tools/wallet-scanWhen to prefer
Choose this endpoint when you need a single unified call to get comprehensive wallet intelligence — balances, tokens, activity, USD values, and safety flags — across Ethereum, Base, Bitcoin, or Solana, without building and maintaining four separate chain integrations. It is especially valuable when sanctions/safety flagging is needed alongside portfolio data in one response.
Side effects
- Invalid or malformed address for the specified chain returns an error
- Unsupported chain identifier causes a 400-level error
- Address with no on-chain history may return empty token_holdings and recent_activity arrays with availability flags set to false
- Network timeout or upstream RPC failure may return a 500-level error
- Rate limiting or insufficient payment may block the request
