What raised the score
  • Top-10 concentration > 70%
  • Liquidity < $10k
  • Token age < 30 days
Exact factors
  • Top-10 concentration > 70% (85.9% total → 85.9% effective; 85.9% in EOAs, 0.0% in contracts — extreme)
  • Liquidity < $10k ($6,302 across 1 pairs — easily drained)
  • Token age < 30 days (still settling)

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

Info

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

This 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 mint/owner authority, mint capability, LP lock/burn state, holder concentration, which are read directly from chain state and from third-party risk registries.I-01

Executive SummaryWhat the contract is and what the review found

This audit of the BlockFall (BLOCK) SPL Token Mint found no critical or high-severity risks based on the provided on-chain facts and external security signals. The mint and freeze authorities are revoked, and no permanent delegate or transfer hook is configured. Holder concentration is low, and liquidity is moderate with normal trading patterns. Third-party risk registry data was clear, and no balance or metadata mutability was detected. Initial holder distribution data was unavailable from chain-native RPC, but top 10 holder percentage was provided by an external security signal.

Technical10/10Low risk

The BlockFall token is implemented using the spl-token-2022 program, indicating a modern token standard. Both the mint authority and freeze authority have been revoked, ensuring no new tokens can be minted and no accounts can be frozen post-launch. No transfer hook is active, meaning transfers are not subject to custom on-chain program logic. The default account state is not frozen, allowing new accounts to receive and transfer tokens immediately. The token also lacks balance mutability, preventing arbitrary adjustments to user balances.

Governance3/10High risk

The token exhibits a healthy holder distribution, with the top 10 token accounts holding only 16.16% of the supply, mitigating risks of whale-induced price volatility. Total DEX liquidity stands at $54,433, which is sufficient to avoid severe slippage for moderate trades. The 24-hour volume to liquidity ratio is 2.62, indicating normal trading activity without signs of wash trading. The DEX pair has been active for 10 days, providing a short but stable initial track record.

Upgrades10/10Low risk

The mint authority and freeze authority are both revoked, preventing any further changes to the token's supply or account freeze status. The token utilizes the spl-token-2022 program, but no upgradable extensions like transfer hook upgradability or transfer fee upgradability are active. Furthermore, the token's metadata is immutable, ensuring that its name, symbol, or image cannot be altered after launch. This configuration provides a high degree of immutability and predictability for token holders.

Final RecommendationWhat to do about this score

Holders should verify on-chain that the mint and freeze authorities remain revoked to ensure the token's fixed supply and unfreezable nature.

While current liquidity is moderate, monitor DEX liquidity and trading volume for any significant changes that could impact exit opportunities. Regularly check for any new flags from independent third-party risk registries, as their assessments can evolve based on new data or developer activity. This token appears to be well-configured from a security perspective based on current data.
