The DERC20 contract is a standard ERC-20 token with additional governance, voting, and vesting capabilities. The protocol relies on a centralized owner to manage minting rates and pool transfer restrictions. While the code follows standard OpenZeppelin patterns, the high level of administrative control over token supply and transferability introduces significant trust requirements for token holders.

Exact factors
- Owner can pause all transfers
- A privileged address controls a switch that decides whether transfers go through
- Mintable supply — no cap found, dilution unbounded
- LP lock status UNKNOWN — the pool's LP could not be read
- Top-10 concentration > 30% (100.0% total → 48.2% effective; 16.2% in EOAs, 80.0% in contracts; 3.8% 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.

Security Findings
MediumCentralized Control Over Token Supply
The owner has the authority to call updateMintRate and release, which can increase the total supply of the token. This allows the owner to dilute the holdings of existing token holders at their discretion.CP-01
Issue
The owner has the authority to call updateMintRate and release, which can increase the total supply of the token. This allows the owner to dilute the holdings of existing token holders at their discretion.
Fix
Implement a timelock on minting functions or transition ownership to a DAO to ensure community oversight of supply changes.
Status
Unresolved
MediumCentralized Control Over Transferability
The owner can use the lockPool and unlockPool functions to enable or disable transfers for specific pools. This grants the owner the ability to effectively freeze user assets or halt trading activity.CP-05
Issue
The owner can use the lockPool and unlockPool functions to enable or disable transfers for specific pools. This grants the owner the ability to effectively freeze user assets or halt trading activity.
Fix
Restrict the use of pool locking to emergency scenarios only and document the criteria for such actions to provide clarity to users.

InfoWho holds the supply
The ten largest holders own 100.0% of supply. Of that, 3.8% burned — not holders that can sell, so excluded from the concentration score. What remains: 16.2% in wallets, 80.0% in other contracts. The deployer/owner wallet itself holds 16.2%. 11 holders in total.QA-HOLDERS

Analysis
AI Copilotas of audit · Oct 25The architecture leverages well-audited OpenZeppelin libraries for ERC-20, Votes, and Permit functionality. 7.1 Architecture and 7.2 Code Security are robust, utilizing standard patterns for state management. 7.3 Access Control is correctly implemented using Ownable, though it grants extensive power to the owner. 7.6 External dependencies are limited to standard libraries, minimizing integration risks.
7.4 Economic and 7.5 Governance aspects are centralized under the owner's control. The owner can influence supply through minting and restrict liquidity via pool locking. While inflation is capped at 2% annually, the ability to trigger minting and lock pools creates a high dependency on the owner's integrity. 7.8 Operations are transparent but rely on the owner's timely execution of administrative functions.
7.7 Upgrades are not supported as the contract is not a proxy. This ensures immutability of the logic, which is a strength for security. No upgrade-related risks are present.
To improve security, consider transitioning the ownership to a multi-signature wallet or a decentralized governance contract to mitigate the risk of a single point of failure.
Additionally, implementing a timelock for sensitive administrative functions like updateMintRate would provide transparency and protection for token holders against sudden supply changes.
