Executive Summary
Between June 20-22, 2026, Cipher Zero scanned 440 verified smart contracts on Base mainnet.
| Finding | Percentage |
|---|---|
| SELFDESTRUCT enabled | 97% |
| tx.origin used in sensitive logic | 91% |
| Unchecked low-level calls | 78% |
| Missing reentrancy guard | 67% |
| Centralized ownership (not renounced) | 82% |
| 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.
