How this service works
The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.
Output
Returns a list of detected sandwich attack incidents associated with the given address on the specified chain, including attacker addresses, affected transaction hashes, timestamps, and the estimated value extracted from each attack.
Example use cases
Protect trading wallets from MEV attacks
“I've been noticing some weird slippage on my trades lately. Can you check if my wallet has been getting sandwiched by MEV bots and show me the damage?”
Audit smart contract security risks
“We're deploying a new DEX contract on Polygon. Before we go live, can you scan similar contracts in the same ecosystem to see how often they get hit by sandwich attacks?”
Investigate suspicious transaction patterns
“This address keeps appearing in my transaction history with tiny amounts stolen. Can you check if it's being targeted by sandwich bots and tell me how much total value has been extracted over time?”
Technical details
Endpoint
GEThttps://chainray.online/sandwich-scanner/%7Baddress%7DWhen to prefer
Use this endpoint when you need to determine whether a specific wallet or smart contract has been targeted by MEV sandwich bots, quantify the financial damage, or investigate suspicious transaction patterns around a known address. Prefer this over generic transaction history endpoints when the specific concern is sandwich/MEV exploitation.
Side effects
- Invalid or malformed address returns 400 error
- Unsupported chain identifier returns error or empty results
- Address with no transaction history returns empty sandwich attack list
- Payment failure via x402 returns 402 Payment Required
- Network congestion or chain RPC unavailability causes timeout or 503
