How the owner could rug you

None of the common owner-side rug mechanisms were found in the code. That is not a clean bill of health — see the limits below.

⚪Contract cannot mint new tokens
Not found
⚪No ability to pause or block transfers
Not found
⚪No address blacklist functionality
Not found
⚪No configurable transfer fee/tax
Not found
⚪Contract is not upgradeable via proxy
Not found
⚪No privileged withdrawal of user funds
Not found
⚪No owner/admin role exists
Not found

This checks only what the code can do. It cannot see whether liquidity is locked, how concentrated holders are, or what the team intends — those need live on-chain data. Absence of these mechanisms is not proof a token is safe.

What this could cost you

How much money would you put into this? We'll show you what you could actually lose — in dollars, not just a scary word like "risk."

None of the common rug mechanisms were found, so there's nothing to calculate against here. That's not the same as "safe" — see the limits above.

Scope of this review

This contract's code is 26,412 characters (after removing comments and whitespace) — only the first 9,000 were analyzed, so parts of it were not examined. That's the real reason, not a vague size limit: 17,412 characters were cut off the end. The contract's own code was read first, so what was cut is mostly shared library code.

What the code allows

Mint authority
Not found

Evidence: No mint function or role; only external pair contract mint is called.

Owner privileges
Not found

Evidence: No owner variable, no onlyOwner modifiers, no Ownable inheritance.

Transfer restrictions
Not found

Evidence: No blacklist, no pause flag, no gating logic before token transfers.

Fees on transfer
Not found

Evidence: No fee state variable or setter; swap calculations use library amounts directly.

Upgradeability
Not found

Evidence: No proxy pattern, no admin that can change implementation.

Pausable functionality
Not found

Evidence: No pause() / unpause() functions or modifiers.

Ownership status
Not found

Evidence: No owner address stored; constructor only sets immutable factory and WETH.

Worth reading yourself

  • ›immutable factory and WETH addresses set in constructor
  • ›receive() only accepts ETH from WETH contract
  • ›All liquidity and swap functions interact with external pair contracts; no internal state that can be altered by an admin

What this did not check

  • ›Source code was truncated at 9000 characters; any code beyond the visible portion could introduce owner/admin logic not captured here
  • ›Liquidity lock status, holder concentration, and actual on‑chain balances are not visible in the source and were not checked

Automated review of verified source only. Not an audit. Does not cover on-chain state, holder distribution, liquidity, or deployer behavior. It cannot tell you whether a token is safe or whether to buy it. Absence of a finding is not evidence that a contract is sound — it may mean the relevant code was not readable, not verified, or not reached.

Want more than the free read?

A real security researcher personally reads this contract's verified source — not an automated re-run of the free check.

What's checked

The same 7 owner-power categories as the free check — mint authority, ability to disable trading, blacklist power, mutable fees, upgradeability, privileged withdrawal, and whether ownership is still active — plus 4 categories the free tier doesn't cover: exact current fee values and where they're set, whether ownership itself can be transferred (and to whom), any hardcoded or owner-settable exceptions to fees/limits/blacklist, and external contracts this one calls out to and trusts.

How it's done

I read the contract's actual verified source directly — no token-window truncation, since a person isn't limited by an LLM's context size the way the free tier is. Every finding cites the specific function or modifier it comes from; if the code doesn't determine something, the report says so instead of guessing.

What you get

A written report emailed to you within 24 hours: a plain-English summary, every finding with its evidence, and what the review could not determine from source alone.

Disclaimer: this is a capability review of verified source code, not a formal security audit and not investment advice. It reports what the contract's owner/admin technically CAN do — it does not check on-chain state, liquidity depth, holder concentration, or deployer behavior, and it does not certify a contract as safe.

This is a surface read

It reports capabilities visible in source. It does not model economics, test exploit paths, or reason about how contracts interact. A real review does — with runnable proofs for anything it claims.
