How this service works
Static search of a VERIFIED Ethereum contract's Solidity source (Blockscout) for max-wallet, max-transaction and cooldown rules, with the matching lines. Unverified contracts are reported as such, not guessed. Bytecode-only and non-Ethereum chains are not covered; a hit is a clue, not proof of a trap.
Output
A JSON object containing the contract name, verification status, compiler version, Blockscout source URL, a verdict (e.g. LIMIT_RULES_FOUND or NO_LIMIT_RULES), and a findings array listing each rule type found (max-wallet, max-transaction, cooldown) with a count of matching lines and example line numbers and text. Includes a note about limitations (e.g. limits set via owner calls or upgrades may not be visible), plus a timestamp of when the check was performed.
Example use cases
Pre-buy token safety check
“Before I buy into this token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, can you check the contract source for any max-wallet or max-transaction restrictions that could trap my investment?”
DeFi research due diligence
“I'm writing a report on meme coin mechanics — can you pull the anti-whale rules from the verified Solidity source for the PEPE token contract at 0x6982508145454ce325ddbe47a25d4ec3d2311933 and show me the actual lines that define them?”
Bot trading limit detection
“I'm building a trading bot and need to know if 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE has any cooldown or holding-cap rules in its contract source that would block rapid buys — can you check?”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/anti-whale-limit-detector?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, source-code-level scan of a verified Ethereum contract for anti-whale rules (max wallet, max transaction, cooldown) and want matched line evidence — not just a flag. Prefer it over general contract explorers when you want structured, machine-readable output for agent pipelines. Not suitable for unverified contracts, bytecode-only analysis, or non-Ethereum chains.
Side effects
- Unverified contract: returns a report noting the contract is unverified rather than guessing from bytecode
- Non-Ethereum chain address: not supported, no result returned
- Invalid or malformed address: likely returns an error or empty result
- Contract with limits set through owner calls or proxy upgrades: keywords may not appear in source, returning false negative
- Keyword match without enforcement: a hit is flagged as a clue, not confirmed proof of an active trap
