How this service works
Token risk check on Base: upgradeable proxy detection (EIP-1967), ownership renouncement status, real Uniswap V3 liquidity pool presence vs WETH, and mint() function presence
Output
Returns a JSON object indicating whether the contract uses an upgradeable proxy pattern (EIP-1967, UUPS, or Transparent Proxy), the specific upgrade mechanism detected, and any basic red flags or suspicious characteristics found in the contract on Base.
Example use cases
Example prompt
“Can you check if the Base contract at 0x4200000000000000000000000000000000000006 uses any upgradeable proxy pattern like UUPS or Transparent, and flag any red flags I should know about before interacting with it?”
Technical details
Endpoint
GEThttps://cryptointel-production.up.railway.app/contract-checkWhen to prefer
Use this endpoint when you need to quickly assess whether a Base smart contract is upgradeable and who controls the upgrade key — critical before approving large transactions, staking funds, or integrating a DeFi protocol. Prefer this over generic blockchain explorers when you need structured, programmatic output about proxy patterns specifically on Base.
Side effects
- Invalid or malformed contract address returns an error
- Contract address not found on Base network returns not-found error
- Non-contract address (EOA wallet) may return no proxy data
- Network timeout or RPC issues cause 5xx errors
- Missing address query parameter returns validation error
