No code-level findings — an SPL mint exposes no auditable program source

I-01This token is an SPL token mint, not a deployed program: there is no contract source code on-chain for a line-by-line review, so no code-level vulnerability could be identified either way. The assessment on this page therefore rests on holder concentration, which are read directly from chain state and from third-party risk registries.

Category Ratings

TechnicalMedium6/10

The メイちゃん (MEI) token is implemented using the spl-token-2022 program. Both the mint authority and freeze authority have been revoked, ensuring no new tokens can be minted and no existing tokens can be frozen by an external party. There is no transfer hook configured, meaning transfers are not subject to custom on-chain program logic. The default account state is not frozen, allowing new accounts to receive tokens without requiring unfreezing.

GovernanceHigh1/10

The token exhibits moderate holder concentration, with the top 10 accounts holding approximately 40.74% of the total supply. This level does not trigger high concentration warnings. The total DEX liquidity is $24,994, which is sufficient to avoid the 'Very Low Liquidity' flag. The 24-hour volume to liquidity ratio is 5.07, which does not indicate wash trading. The DEX pair has been active for 140 days, providing a reasonable track record.

UpgradesMedium5/10

The token's mint and freeze authorities are revoked, preventing any further changes to supply or account freezing capabilities. The metadata is immutable, ensuring that the token's name, symbol, or image cannot be altered post-launch. No upgradable features like transfer fee or transfer hook are present or configured to be upgradable.

Liquidity Depth

$6.8K

The risk score reads depth across every pair. The volume figure and the volume-to-liquidity ratio elsewhere on this page describe only the pair this audit analysed, so the two are not directly comparable.

What Raised This Score

6 factors

Ownership status UNKNOWN (owner could not be resolved)
Mint capability UNKNOWN (implementation ABI unreadable)
Contract source NOT verified
Top-10 concentration > 70% (86.2% total → 86.2% effective; 86.2% in EOAs, 0.0% in contracts — extreme)
Liquidity NOT locked (owner can withdraw — rug-pull risk)
Liquidity < $10k ($6,802 across 1 pairs — easily drained)

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
