What raised the score
  • Owner can pause all transfers
  • Mintable supply, nominal cap 19669%/year — effectively unbounded
  • Upgradeable proxy — the admin can replace the logic
  • Liquidity not locked
  • Top-10 concentration > 30%
Exact factors
  • Owner can pause all transfers
  • Mintable supply, nominal cap 19669%/year — effectively unbounded
  • Upgradeable proxy — the admin can replace the logic
  • Liquidity NOT locked (100% of the pool) — who holds it cannot be verified
  • Top-10 concentration > 30% (86.8% total → 36.1% effective; 3.8% in EOAs, 80.8% in contracts; 2.2% 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

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.

What the token's controller can do

The contract lets its controller — a ProxyAdmin contract — mint new supply; pause all transfers. Nothing independent vouches for whoever holds them, so each is a live risk to holders.QA-POWERS

Issue

The contract lets its controller — a ProxyAdmin contract — mint new supply; pause all transfers. Nothing independent vouches for whoever holds them, so each is a live risk to holders.

Fix

Check who holds these powers and whether a timelock or multisig stands between them and holders.

Liquidity not locked

0.0% of the pool's LP is burned or time-locked. 100.0% is held, unlocked, by 1 address(es) other than the owner/deployer. One of them — a contract, 0xe875…e34f — holds 99.9% and can remove that share at once; who controls it is not visible on-chain, so it is not treated as an independent provider. Some pools are concentrated-liquidity (V3/V4) positions; shares above are by position as GoPlus reports them.QA-LIQUIDITY

Who holds the supply

The ten largest holders own 86.8% of supply. Of that, 2.2% in DEX pools — not holders that can sell, so excluded from the concentration score. What remains: 3.8% in wallets, 80.8% in other contracts. 2,845 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.

Analysis

AI Copilotas of audit · Nov 5
Executive SummaryWhat the contract is and what the review found

The protocol implements a standard Burn-and-Mint ERC-20 token with UUPS proxy upgradeability and pausable functionality. The architecture relies on OpenZeppelin's battle-tested libraries for access control and proxy management. No critical vulnerabilities were identified in the provided code map. The protocol is highly centralized, granting significant power to the DEFAULT_ADMIN_ROLE and MINTER_ROLE.

Technical7/10Low risk

The contract utilizes standard OpenZeppelin libraries for 7.1 Architecture and 7.2 Code Security. 7.3 Access Control is robust, utilizing role-based permissions for minting, pausing, and administrative tasks. 7.6 External interactions are limited to standard ERC-20 operations, minimizing attack surfaces.

Governance1/10High risk

7.4 Economic risk is present due to the minting capability, which allows for significant supply dilution. 7.5 Governance is centralized under the DEFAULT_ADMIN_ROLE, which controls all administrative parameters. Users should be aware that the owner can pause transfers and mint new tokens at will.

Upgrades1/10High risk

7.7 Upgrades are managed via the UUPS pattern, which is the industry standard for gas-efficient proxy upgrades. The implementation includes 7.8 Operations safeguards such as the DEFAULT_ADMIN_ROLE delay mechanism for administrative changes. This structure ensures that upgrades are controlled and traceable.

Final RecommendationWhat to do about this score

The protocol is well-structured and follows secure coding standards.

To further enhance security, consider implementing a multi-signature wallet or a DAO-based governance structure for the DEFAULT_ADMIN_ROLE to mitigate the risks associated with a single point of failure. Regularly monitor the minting activity and administrative role changes to ensure transparency for token holders. Ensure that the private keys associated with the administrative roles are stored in secure, cold-storage environments.
