How this service works
Base L2 EVM token safety verifier: simulates buy/sell, transfer taxes, honeypot checks, proxy resolution, and liquidity. Pass ?token=<Base ERC-20 address>.
Output
Returns a structured JSON object containing: token address and chain, simulation results (buy/sell success, amounts in/out), contract analysis (proxy status, ownership, flags), liquidity metrics (pool depth, reserves), and a plain-language recommendation summarizing overall safety.
Example use cases
Honeypot check before DeFi trade
“I'm about to swap into this Base token at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 — can you check if it's a honeypot and whether I'd actually be able to sell it afterward?”
Transfer tax discovery for token
“What are the buy and sell transfer taxes on this Base L2 token? Contract is 0x4ed4e862860bed51a9570b96d89af5e1b0efefed — I want to know before I commit funds.”
Liquidity and contract safety audit
“Can you do a full safety audit on Base token 0x940181a94a35a4569e4529a3cdfb74e38fd98631? I need to know about its liquidity, whether the contract is a proxy, and if there are any red flags.”
Technical details
Endpoint
GEThttps://a2a-verifier-production.up.railway.app/verifyWhen to prefer
Use this endpoint when you need a quick, automated safety assessment of an ERC-20 token specifically on the Base L2 network before executing a trade or recommending a token to a user. It is distinct from general Ethereum mainnet scanners and combines buy/sell simulation, honeypot detection, tax analysis, proxy resolution, and liquidity checks in a single call — ideal for DeFi agents that need a holistic risk verdict without calling multiple separate APIs.
Side effects
- Invalid or malformed token address (not a 0x 40-hex-char address) returns a validation error
- Token address not deployed on Base L2 returns a contract-not-found error
- RPC or simulation timeout may return incomplete results
- Unverified or heavily obfuscated contracts may yield limited analysis
- Payment not received (x402) results in 402 Payment Required response
