What raised the score
  • A privileged address controls a switch that decides whether transfers go through
  • Mintable supply β€” no cap found, dilution unbounded
  • LP lock status UNKNOWN β€” the pool's LP could not be read

Exact factors
  • A privileged address controls a switch that decides whether transfers go through
  • Mintable supply β€” no cap found, dilution unbounded
  • LP lock status UNKNOWN β€” the pool's LP could not be read
  • Top-10 concentration > 30% (100.0% total β†’ 48.2% effective; 16.2% in EOAs, 80.0% in contracts; 3.8% burned, locked or in pools excluded)
  • Contract source NOT verified β€” its logic cannot be read

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 (7h old). New tokens carry elevated risk β€” 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.

Security Findings

Privileged Supply Minting and Inflation Control

The contract allows the privileged owner to mint new tokens and adjust the annual inflation rate by calling the updateMintRate(uint256) function. When invoked, it executes mintInflation(), creating new tokens that dilute existing holders up to the hardcoded maximum rate of 2% annually. Additionally, the release() function transfers vested tokens from contract custody to recipients based on vesting schedules.CP-01

Issue

The contract allows the privileged owner to mint new tokens and adjust the annual inflation rate by calling the updateMintRate(uint256) function. When invoked, it executes mintInflation(), creating new tokens that dilute existing holders up to the hardcoded maximum rate of 2% annually. Additionally, the release() function transfers vested tokens from contract custody to recipients based on vesting schedules.

Fix

Subject the updateMintRate function to a transparent timelock contract or direct decentralized DAO governance voting, and consider enforcing strict time-delayed caps before inflation adjustments take effect.

Privileged Pool Transfer Switch Control

The contract contains an administrative transfer-gating mechanism where the owner can call lockPool(address) and unlockPool() to toggle the isPoolUnlocked boolean switch and assign the target pool address. When locked, token transfers or interactions routed through the specified liquidity pool can be restricted or refused, placing secondary market trading under centralized control.CP-05

Issue

The contract contains an administrative transfer-gating mechanism where the owner can call lockPool(address) and unlockPool() to toggle the isPoolUnlocked boolean switch and assign the target pool address. When locked, token transfers or interactions routed through the specified liquidity pool can be restricted or refused, placing secondary market trading under centralized control.

Fix

Remove the ability to arbitrarily lock liquidity pools once trading has commenced, or strictly enforce automated time-based unlocks and multisig/timelock safeguards to avoid centralized trade restrictions.

Who holds the supply

The ten largest holders own 100.0% of supply. Of that, 3.8% burned β€” 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%. 10,027 holders in total.QA-HOLDERS

Analysis

AI Copilotas of audit Β· Oct 24
Executive SummaryWhat the contract is and what the review found

The audit evaluated the DERC20 token contract deployed on Base. The codebase implements a standard OpenZeppelin-derived ERC-20 structure with voting extensions (ERC20Votes), linear vesting logic, and an inflation mechanism capped at 2% annually. However, centralization vectors exist around transfer gating and mint rate manipulation controlled by a privileged owner address.

Technical4/10Medium risk

Under 7.1 Architecture and 7.2 Code Security, the contract relies heavily on robust OpenZeppelin primitives, including ERC20Votes, ERC20Permit, and standard Math libraries. Standard safe math protections native to Solidity 0.8.26 prevent integer overflows, and vesting releases utilize explicit linear math. However, under 7.6 External and 7.8 Operations, pool gating introduces operational dependencies where transfer paths can be restricted. For example, the lockPool and unlockPool mechanisms directly modulate pool interaction paths, posing transactional risk if improperly maintained.

Governance3/10High risk

In terms of 7.4 Economic considerations, the token enforces a hardcoded upper limit on yearly inflation at 2% (MAX_YEARLY_MINT_RATE_WAD), preventing hyperinflationary abuse. Additionally, 7.5 Governance is strengthened by multi-signature ownership controls (3-of-6 threshold) rather than an unconstrained EOA. Nevertheless, under 7.3 Access Control, the contract owner possesses unilateral authority to call updateMintRate and trigger minting, as well as halt pool liquidity via lockPool. An example of this risk is the owner's ability to trigger immediate supply dilution through periodic minting intervals.

Upgrades4/10Medium risk

Regarding 7.7 Upgrades, the deployed DERC20 contract is non-upgradeable and deployed without proxy indirection, preventing unauthorized implementation swaps. The contract relies on static storage layouts and immutable inheritance patterns for its voting and token behaviors. However, administrative functions such as transferOwnership and updateTokenURI retain mutable parameters that alter token presentation and operational management. For instance, modifying the token URI or transferring ownership without a two-step timelocked confirmation can lead to governance handover risks.

Final RecommendationWhat to do about this score

Implement a formal timelock and decentralized governance module to intermediate all administrative calls currently restricted to onlyOwner, particularly lockPool, unlockPool, and updateMintRate.

Additionally, adopt a two-step ownership transfer pattern (such as OpenZeppelin's Ownable2Step) to prevent accidental transfer of administrative privileges. Consider bounding pool locking mechanics so that user funds cannot be permanently restricted in secondary liquidity pools, and ensure transparent emission schedules are published on-chain to provide predictable supply dynamics for token holders.
