What raised the score
  • Owner can change the buy/sell tax
  • A privileged address can change transfer or wallet limits
  • Liquidity < $50k
  • Code: ETH trapped in contract
  • Code: Use of tx.origin for authorization
Exact factors
  • Owner can change the buy/sell tax
  • A privileged address can change transfer or wallet limits
  • Liquidity < $50k ($45,561 across 1 pairs — thin market)
  • Code: ETH trapped in contract (Medium, static analysis)
  • Code: Use of tx.origin for authorization (Medium, static analysis)

Each factor is an on-chain fact recorded at the time of this analysis. The score is computed from them by a deterministic function, so the same contract returns the same score for anyone who runs the audit. How scores are computed

Early-stage analysis. This token has limited on-chain history (3h old). New tokens carry elevated risk — data may change rapidly. Always verify independently before investing.

How holder types affect the score

Share held by contracts — treasury, vesting, bridge or staking — is discounted against share held by wallets when the score is computed: a contract cannot decide to sell the way an anonymous holder can, though it can still be drained or voted to sell. Effective concentration is the figure the risk score is actually calculated from.

Security Findings

3 Medium1 Low6 Info
Medium

ETH trapped in contract

The contract accepts ETH but lacks a mechanism to withdraw it, meaning any ETH sent to the contract will be permanently locked.CD-01

Issue

The contract accepts ETH but lacks a mechanism to withdraw it, meaning any ETH sent to the contract will be permanently locked.

Fix

Add a function restricted to the owner that allows for the withdrawal of accidentally sent ETH.

Status

Unresolved

Medium

Use of tx.origin for authorization

The _getTaxWithPoolState function uses tx.origin to determine tax rules, which is vulnerable to phishing attacks where a user is tricked into calling a malicious contract that then interacts with this token.CD-02

Issue

The _getTaxWithPoolState function uses tx.origin to determine tax rules, which is vulnerable to phishing attacks where a user is tricked into calling a malicious contract that then interacts with this token.

Fix

Replace tx.origin with msg.sender to ensure that the immediate caller is the one being evaluated for tax rules.

Status

Unresolved

Medium

Owner can modify transfer fees

The owner has the ability to change the tax fees applied to token transfers via the finalizeMigration function, which could be used to unexpectedly increase costs for users.CP-07

Issue

The owner has the ability to change the tax fees applied to token transfers via the finalizeMigration function, which could be used to unexpectedly increase costs for users.

Fix

Implement a timelock or a maximum fee cap to limit the owner's ability to change tax rates arbitrarily.

Status

Unresolved

Low

Owner can modify trading limits

The owner can adjust transfer or wallet limits through the finalizeMigration function, potentially restricting user access to their tokens.CP-08

Issue

The owner can adjust transfer or wallet limits through the finalizeMigration function, potentially restricting user access to their tokens.

Fix

Document these limits clearly in the project's public documentation and consider using a multi-sig wallet for the owner address.

Info

Who holds the supply

The ten largest holders own 20.7% of supply. Of that, 8.5% in DEX pools — not holders that can sell, so excluded from the concentration score. What remains: 9.8% in wallets, 2.4% in other contracts. 1,684 holders in total.QA-HOLDERS

Fix

Watch the largest wallets that are not exchanges, pools or locks — those are the ones that can move the price.

100.0% of the pool's LP is burned or time-locked. 100.0% of the LP tokens were sent to a burn address — that liquidity can never be withdrawn by anyone.

Asset class: Project token

Basis: no class-specific evidence. Tokenomics — Supply: fixed — the contract has no mint function. Control: a role-controlled contract. Code: not upgradeable (no proxy). Fees: 3% on buy, 3% on sell.

Info

Recently launched — less than a day of market history

The token's oldest DEX pool is less than a day old. Age is not part of the risk score — a new token is not a risky one by default — but a short history means fewer trades and holder changes behind the facts in this report.QA-RECENT

Issue

The token's oldest DEX pool is less than a day old. Age is not part of the risk score — a new token is not a risky one by default — but a short history means fewer trades and holder changes behind the facts in this report.

Fix

Re-check ownership, liquidity and holder distribution as the token matures; those are the facts that move early.

Analysis

AI Copilotas of audit · Nov 7
Executive SummaryWhat the contract is and what the review found

The FlapDirectTaxToken is a minimal clone implementation of an ERC-20 token with integrated tax and anti-sniper mechanisms. While the core token logic follows standard patterns, the contract includes centralized administrative controls over transfer fees and trading limits. The audit identified risks related to trapped ETH and the use of tx.origin for authorization, which could impact security under specific conditions.

Technical8/10Low risk

The architecture utilizes EIP-1167 minimal clones to ensure immutable logic deployment. Code security is generally robust, adhering to standard ERC-20 interfaces and safe math practices via Solidity 0.8.x. However, the reliance on tx.origin for internal tax logic introduces potential security vulnerabilities against malicious contract interactions. Coverage includes 7.1 Architecture, 7.2 Code Security, 7.3 Access Control, 7.6 External, and 7.8 Operations.

Governance7/10Low risk

Economic parameters, including tax rates and anti-sniper windows, are fully controlled by the contract owner. This centralized governance allows for rapid response to market conditions but poses a risk to token holders if the owner account is compromised. Coverage includes 7.4 Economic and 7.5 Governance.

Upgrades8/10Low risk

The contract is deployed as an EIP-1167 minimal clone, which is inherently immutable. There is no upgrade path for the logic contract, ensuring that the rules defined at deployment remain consistent. Coverage includes 7.7 Upgrades.

Final RecommendationWhat to do about this score

It is recommended to implement a withdrawal function to recover any ETH accidentally sent to the contract address.

Additionally, refactor the tax logic to rely on msg.sender rather than tx.origin to prevent potential security bypasses via intermediate contract calls.
