How this service works
Resolve a token symbol or contract address to the canonical Base contract, so an agent swapping or accepting 'USDC' gets the real one. Catches lookalike and impostor contracts sharing a symbol.
Output
Returns the canonical contract address for the queried token on Base, along with verification status indicating whether the queried address or symbol maps to the legitimate contract. Flags lookalike or impostor contracts that share the same symbol but are not canonical.
Example use cases
Safe DeFi swap verification
“I'm about to swap into USDC on Base — can you verify that the contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is the legitimate canonical USDC and not a scam token sharing the same symbol?”
Agent wallet funding safety check
“My agent is about to accept a USDC payment from a counterparty — can you check if the token contract they're sending from is the real USDC on Base or an impostor?”
Token address lookup before listing
“I'm building a token list for my DEX aggregator — can you resolve the symbol WETH to its canonical contract address on Base and flag any known lookalikes with the same symbol?”
Technical details
Endpoint
GEThttps://chainverdict.xyz/v1/verify/token/:qWhen to prefer
Use this endpoint whenever an AI agent is about to perform a token swap, accept a payment, or interact with any ERC-20 on Base where the contract address source is not hard-coded and trusted. It is specifically designed to catch the impostor/lookalike token attack vector — where a malicious token shares a symbol with a legitimate one — which generic blockchain lookup APIs do not explicitly guard against.
Side effects
- Unknown symbol or address returns a not-found or unverified response
- Querying a token not deployed on Base returns an error or empty result
- Malformed contract address (wrong length or checksum) may return a validation error
- Network or chain data unavailability causes a service error
