x402
EVM Multi-Chain Address Activity Scanner is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-01).
Checks a given EVM wallet address across ten EVM-compatible chains to determine which networks it has ever had activity on

How this service works
Which of ten EVM chains has this address ever touched — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object indicating success, a receipt with transaction hash and payment details, and a timestamp. The core result identifies which of ten supported EVM chains the queried address has ever had on-chain activity on, allowing the caller to understand cross-chain presence of a wallet.
Example use cases
Cross-chain wallet due diligence
“Before I send funds to this address 0xAbCd1234567890abcdef1234567890abcdef1234, can you check which EVM chains it has any history on so I know it's a real, active wallet?”
DeFi user chain footprint research
“I'm researching this wallet 0xdead000000000000000042069000000000000000 — can you tell me which of the major EVM networks it has ever touched?”
Airdrop eligibility pre-screening
“We want to airdrop tokens to 0xBEEF0000000000000000000000000000000beef only if it's been active on certain chains — can you scan it across all ten EVM networks and tell me which ones it has activity on?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/evm-multi-chain-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, broad cross-chain presence check for a wallet across ten EVM networks in a single call, rather than querying each chain individually. It is ideal for due diligence, fraud detection, airdrop screening, or user profiling where you need to know which chains an address has ever interacted with, not just the current state on one chain.
Side effects
- Invalid or malformed address (not a valid 0x-prefixed 40-hex-character string) returns an error
- Payment failure or insufficient USDC balance causes a 402 rejection
- Network timeouts if one or more of the ten chains are temporarily unreachable
- Address with zero activity on all chains returns an empty or all-false result
- Rate limiting if too many calls are made in quick succession
