The DERC20 contract is a standard ERC-20 implementation with additional governance and vesting features. The protocol relies on a centralized owner to manage minting rates and pool transfer restrictions. While the code follows standard OpenZeppelin patterns, the high degree of administrative control presents a significant centralization risk to 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 Minting Authority
The owner has the ability to mint new tokens via the updateMintRate and release functions. This allows the owner to increase the total supply, which dilutes the value of existing holdings.CP-01
Issue
The owner has the ability to mint new tokens via the updateMintRate and release functions. This allows the owner to increase the total supply, which dilutes the value of existing holdings.
Fix
Implement a timelock on minting-related functions or transition ownership to a decentralized governance model to ensure community oversight.
Status
Unresolved
MediumCentralized Transfer Control
The owner can use the lockPool and unlockPool functions to toggle a switch that determines whether transfers are permitted. This gives the owner the power to effectively freeze user assets or halt trading.CP-05
Issue
The owner can use the lockPool and unlockPool functions to toggle a switch that determines whether transfers are permitted. This gives the owner the power to effectively freeze user assets or halt trading.
Fix
Restrict the use of transfer-halting functions to emergency scenarios only and consider adding a public event log or community-based veto mechanism.

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%. 2,747 holders in total.QA-HOLDERS

Analysis
AI Copilotas of audit · Oct 22The architecture utilizes robust OpenZeppelin libraries for ERC-20 and governance functionality. 7.1 Architecture is modular, and 7.2 Code Security is high due to the use of audited standard implementations. 7.3 Access Control is strictly enforced via Ownable, though it grants extensive power to the owner. 7.6 External dependencies are limited to standard, well-vetted libraries.
7.4 Economic and 7.5 Governance aspects are heavily centralized. The owner has the ability to mint tokens and halt transfers, which directly impacts the token's economic stability. While minting is capped at 2% annually, the lack of a timelock or multi-sig requirement for these actions increases the risk of abuse.
7.7 Upgrades are not applicable as the contract is not a proxy. 7.8 Operations are straightforward, relying on the owner to trigger vesting releases and update parameters. The lack of upgradeability ensures immutability of the core logic, which is a positive security trait.
To improve security, the protocol should transition ownership to a multi-signature wallet or a decentralized governance contract to prevent single-point-of-failure risks.
Implementing a timelock on sensitive functions like updateMintRate would provide transparency and allow the community to react to significant economic changes. Additionally, consider documenting the exact logic of the pool locking mechanism to ensure users understand the conditions under which their ability to transfer tokens might be restricted. Regular audits of the owner's operational procedures are recommended to ensure that administrative keys are managed securely.
