7 EOT / And several useful pro tips: - Proper design = fewer sleepless nights for devs & users - Consider each function as a potential entry point - Explicitly define access rules for all sensitive operations - And never trust user input without validation 🛡️ #blockchainsecurity

6/❗️ Important: If you vibe code smart contracts for your #crypto project using AI, keep in mind that LLMs can't handle access control design part for you as there's no one-size-fits-all approach to implementing access control, and there are too many varied examples over the net

5/ Prevention: - Ensure initialization functions can only be called once and only by authorized entities - Use access control patterns like Ownable or RBAC to manage permissions - Use modifiers like onlyOwner or custom roles to sensitive functions - Test and audit your code 🔍

4/ Common cases: - No access modifiers: functions left public when they should be private / restricted - Weak role management: admins / minters are not properly verified - Initializer exploits: unprotected initialization functions that anyone can call post-deployment

3/ Hackers seek and exploit access control vulnerabilities to gain unauthorized access to critical functions and data within the contract and abuse the contract processes #cybersecurity

2/ Access control is how a smart contract defines and restricts who can call critical functions (e.g. withdrawing funds or updating settings)

🔐 Access control vulnerabilities are among the top causes of smart contract hacks. Let’s take a quick look at what improper access control attacks are & how to mitigate them 🧵👇 #DeFi #crypto #DeFiSecurity
