Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Malicious Code: A backdoor validation mechanism ('IsAdmin') bypassed standard security procedures, allowing unauthorized administrative actions. Rigorous auditing of signature-verification pathways is required to prevent re-introduction of bypass checks.
Access Control: Lack of centralized permission checks led to vulnerabilities where messages could skip vital authorization steps. Ensuring all entry-point handlers flow through a unified enforcement mechanism is critical.
Denial of Service: Creation of invalid coin values (e.g., negative amounts via sdk.NewInt64Coin) triggered critical state-machine panics, halting block production. All inputs to stateful SDK functions must be validated beforehand.
