How this service works
Returns a grade (BASED/MID/COOKED/RADIOACTIVE) based on the contract's own state: code size, name, symbol, decimals… Returns: an AI-written token verdict on one token contract: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the contract's own state), a one-liner and a roast, and the facts read: code size, name, symbol, decimals, supply, owner(), proxy slots. It does not read holders, liquidity or price and makes no safety or legitimacy call. Query: token (token contract, 0x + 40 hex).
Output
Returns a grade enum (BASED/MID/COOKED/RADIOACTIVE) with a short one-liner and a roast string, plus raw facts: is_contract, code_bytes, name, symbol, decimals, total_supply, owner address, owner_renounced boolean, proxy_slot details, proxy_implementation address, proxy_slots_checked list, and erc20_shaped flag. RADIOACTIVE means not a contract or not ERC-20 shaped. COOKED means proxy slot is set AND owner is live. MID means one of those. BASED means neither.
Example use cases
Quick rug-risk screen before buying
“Before I ape into this new token, can you run a verdict on 0x6B175474E89094C44Da98b954EedeAC495271d0F and tell me if the owner is still live and whether there are any proxy upgrade slots set?”
Comparing two tokens for trustworthiness
“I'm looking at two tokens — 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE — can you grade both and tell me which one is more BASED based on their on-chain contract state?”
Verify a new launch contract isn't a proxy
“This new token just launched at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — can you check if it's ERC-20 shaped, whether the owner has been renounced, and if any proxy implementation slots are set? I want the full roast.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/token_verdict?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, purely on-chain structural assessment of an Ethereum token contract — checking for proxy upgradeability, live ownership, and ERC-20 validity — without needing holder counts, liquidity depth, or price data. Ideal for pre-trade screening, contract auditing workflows, or flagging suspicious proxy patterns. Not a replacement for full security audits or liquidity analysis.
Side effects
- Invalid address format (not 0x + 40 hex) returns validation error
- Address is not a deployed contract — grade returns RADIOACTIVE with is_contract: false
- Contract is not ERC-20 shaped (no decimals/totalSupply) — grade is RADIOACTIVE
- RPC node unavailable or timeout causes service error with ok: false
- Token contract is valid ERC-20 but has no owner() function — owner field null
