| Finding | Percentage |
|---|---|
| SELFDESTRUCT enabled | 97% |
| tx.origin used in sensitive logic | 91% |

| No verified source on Basescan | 34% |
?? Critical: SELFDESTRUCT in 97% of Contracts
When enabled in a proxy pattern, an attacker who gains admin access can call selfdestruct on the implementation, making all proxies unusable and locking user funds permanently.
?? tx.origin - Phishing Vulnerability in 91%
Using tx.origin for authorization is a well-known anti-pattern. Any contract in the call chain inherits the same authorization.
?? Unchecked Low-Level Calls - 78%
Low-level calls return a boolean success value. 78% of contracts don't check it. When a call fails silently, contract state becomes inconsistent.
