The DERC20 contract is a standard ERC-20 implementation with additional governance-controlled minting and transfer-restriction capabilities. While the code follows standard OpenZeppelin patterns, the centralization of power in the owner address poses a significant risk to token holders. The protocol demonstrates 7.1 Architecture (standard), 7.2 Code Security (high), 7.3 Access Control (centralized), 7.4 Economic (inflationary), 7.5 Governance (owner-centric), 7.6 External (standard), 7.7 Upgrades (N/A), and 7.8 Operations (standard).

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 Minting Authority
The owner has the authority to mint new tokens via the updateMintRate and release functions. This allows the owner to increase the total supply, which directly dilutes the value of existing tokens held by users.CP-01
Issue
The owner has the authority to mint new tokens via the updateMintRate and release functions. This allows the owner to increase the total supply, which directly dilutes the value of existing tokens held by users.
Fix
Implement a decentralized governance mechanism or a hard-coded minting schedule that limits the owner's ability to arbitrarily increase supply.
Status
Unresolved
MediumCentralized Control Over Token Transfers
The owner can toggle the isPoolUnlocked switch via the lockPool and unlockPool functions. This allows the owner to unilaterally halt or resume token transfers, effectively freezing user assets at will.CP-05
Issue
The owner can toggle the isPoolUnlocked switch via the lockPool and unlockPool functions. This allows the owner to unilaterally halt or resume token transfers, effectively freezing user assets at will.
Fix
Remove the ability for the owner to pause transfers, or implement a multi-signature requirement and a public notice period before any transfer restrictions are applied.

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%. 3,034 holders in total.QA-HOLDERS

Analysis
AI Copilotas of audit · Oct 22The contract utilizes well-audited OpenZeppelin libraries for core ERC-20 functionality. Code quality is high, with clear separation of concerns and standard implementation of EIP-712 and ERC-20Votes. The logic for vesting and inflation is correctly implemented, though it relies heavily on the owner's timely execution of administrative functions.
The economic model is inflationary, allowing the owner to mint tokens up to a 2% annual cap. This provides the owner with significant control over token supply and holder dilution. The governance structure is entirely centralized, lacking a timelock or multi-signature requirement for sensitive operations.
The contract is not upgradeable, which provides immutability for the core logic. This eliminates risks associated with proxy storage collisions or malicious implementation swaps. Users can rely on the current code remaining unchanged throughout the contract's lifecycle.
It is recommended to transition the owner role to a decentralized multi-signature wallet or a DAO governance contract to mitigate the risks of single-point-of-failure.
Additionally, implementing a timelock on sensitive functions like updateMintRate and lockPool would provide transparency and allow the community to react to administrative changes.
