What raised the score
  • Owner can pause all transfers
  • A privileged address controls a switch that decides whether transfers go through
  • Owner can blacklist or freeze individual holders
  • Owner can change the buy/sell tax
  • Liquidity not locked
  • Top-10 concentration > 70%
Exact factors
  • Owner can pause all transfers
  • A privileged address controls a switch that decides whether transfers go through
  • Owner can blacklist or freeze individual holders
  • Owner can change the buy/sell tax
  • Liquidity NOT locked (93% of the pool) — held by independent providers — market-depth risk
  • Top-10 concentration > 70% (100.0% total → 99.8% effective; 99.8% in EOAs, 0.0% in contracts; 0.2% burned, locked or in pools excluded)

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 (5d 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.

LP tokensNot locked

The LP tokens of the analysed pool are not locked or burned, so whoever holds them can withdraw that liquidity.

Centralized Control Over Trading Status

The owner can use the setCanBuy and setCanSell functions to completely halt trading for all users. This allows the owner to prevent any buying or selling activity at their discretion.CP-05

Issue

The owner can use the setCanBuy and setCanSell functions to completely halt trading for all users. This allows the owner to prevent any buying or selling activity at their discretion.

Fix

Implement a time-lock or a decentralized voting mechanism for these functions to prevent sudden, unilateral trading halts.

Status

Unresolved

Medium

Arbitrary Blacklisting of Holders

The setBlacklisted function allows the owner to prevent specific addresses from transferring or selling their tokens. This effectively gives the owner the power to freeze user assets.CP-06

Issue

The setBlacklisted function allows the owner to prevent specific addresses from transferring or selling their tokens. This effectively gives the owner the power to freeze user assets.

Fix

Remove the blacklist functionality or restrict its use to a transparent, community-voted process for addressing malicious activity only.

Unresolved

Medium

Owner-Controlled Transfer Fees

The setTaxes function allows the owner to change the buy and sell tax rates at any time. This could be used to extract value from users or make the token effectively untradeable.CP-07

Issue

The setTaxes function allows the owner to change the buy and sell tax rates at any time. This could be used to extract value from users or make the token effectively untradeable.

Fix

Set a hard cap on the maximum tax rate that can be set by the owner and implement a time-lock for any changes to the tax parameters.

Who holds the supply

The ten largest holders own 100.0% of supply. Of that, 0.2% in DEX pools — not holders that can sell, so excluded from the concentration score. What remains: 99.8% in wallets, 0.0% in other contracts. 1,577 holders in total.QA-HOLDERS

Analysis

AI Copilotas of audit · Oct 31
Executive SummaryWhat the contract is and what the review found

The YUN token is a standard ERC-20 implementation with added centralized controls for taxes, blacklisting, and trading status. While the core token logic follows standard patterns, the contract grants the owner significant power to restrict user activity and modify economic parameters. 7.1 Architecture: Standard ERC-20 with custom hooks. 7.2 Code Security: Standard implementation. 7.3 Access Control: Centralized owner control. 7.4 Economic: Owner-defined tax rates. 7.5 Governance: None. 7.6 External: No external integrations. 7.7 Upgrades: None. 7.8 Operations: Owner-managed.

Technical6/10Medium risk

The contract utilizes a standard OpenZeppelin-style ERC-20 structure, ensuring compatibility with common DeFi protocols. The code is clean and follows established patterns for token transfers. However, the inclusion of custom logic in the _transfer path introduces centralized points of failure. The implementation of tax and blacklist logic is straightforward and correctly uses the onlyOwner modifier.

Governance1/10High risk

The economic model is entirely controlled by the contract owner, who can adjust buy/sell taxes at will. This creates a high risk for token holders, as the owner could theoretically set taxes to 100% or disable trading entirely. There are no governance mechanisms or time-locks to protect users from sudden changes in token utility or economic policy.

Upgrades6/10Medium risk

The contract is not upgradeable, meaning the logic is immutable once deployed. This eliminates risks associated with proxy-based upgrade vulnerabilities. However, it also means that any errors in the current logic cannot be patched without a migration.

Final RecommendationWhat to do about this score

Token holders should be aware that the contract owner possesses absolute control over the ability to trade and the economic cost of transfers.

It is recommended that the owner renounce ownership or transition to a multi-signature wallet or decentralized governance model to mitigate the risk of unilateral actions. Users should monitor the contract for any changes to the tax rates or trading status, as these can be modified at any time by the owner. No further technical changes are required for the current logic, but the centralization of power remains a significant concern for long-term holders.
