How this service works
Rule-based risk check for any ERC-20 token on Base, straight from the chain and without AI - contract and proxy (upgradeable?), owner and whether it was renounced, risky owner functions in the bytecode (mint, pause, blacklist, fees, trading switches), owner share of supply and DEX liquidity on Uniswap V2/V3 and Aerodrome in USD. Returns ok, caution or avoid with reasons in under two seconds. Technical check, not investment advice.
Output
Returns a risk verdict of 'ok', 'caution', or 'avoid', along with specific reasons. Includes whether the contract is a proxy/upgradeable, the owner address and renouncement status, detected risky functions in the bytecode (mint, pause, blacklist, fee manipulation, trading switches), the owner's share of total supply, and USD liquidity figures across Uniswap V2, Uniswap V3, and Aerodrome DEXes.
Example use cases
Pre-trade token safety check
“Before I buy into this token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, can you check if the contract is safe — look for mint or blacklist functions, whether the owner renounced control, and how much liquidity is on Uniswap or Aerodrome?”
DeFi bot rug-pull guard
“My trading bot is about to ape into a new Base token at 0x0578d8A44db98B23BF096A382e016e29a5Ce0ffe — can you do a quick on-chain risk scan and flag it as ok, caution, or avoid before it executes?”
Research new Base token launch
“I'm seeing a lot of hype around a new token on Base with address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you check the contract for proxy upgrades, risky owner functions, and what the owner's share of supply looks like?”

Endpoint
POSThttps://x402op-edge-39830b.fly.dev/p/base-token-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, on-chain risk signal for a Base ERC-20 token — no AI hallucination risk, no off-chain data sources, sub-2-second response. Prefer it over AI-based token analysis when you need auditable, rule-based verdicts. Prefer it over generic blockchain explorers when you want a structured risk summary (owner functions, liquidity, supply share) rather than raw chain data. Best suited for pre-trade checks in trading bots, DeFi dashboards, or user-facing token vetting flows on Base mainnet or Base Sepolia.
Side effects
- Invalid or malformed contract address returns a validation error
- Contract address exists but is not an ERC-20 token — may return incomplete data or error
- Token has no DEX liquidity — liquidity fields return zero or null
- Network mismatch (specifying base-sepolia for a mainnet token) returns no data
- RPC or on-chain data unavailability may cause timeout or partial response
- Very new tokens with no deployment history may have limited analyzable bytecode
