Day32/1001 chasing the bag with @cantinaxyz and learning with @CyfrinUpdraft ✅The danger of Reentrancy. Allowing the contract to send Eth before updating balance will give the hacker access to keep hitting send till wallet is drained. Remember the last DAO hack #Solidity #Rust #Web3 #Solana

Why you should use Multi-Signature Wallet. Always Store Your Signer Keys Separately. The strength of multi-sig security lies in how you distribute the private keys of your signer wallets. Never keep all your signer keys on one device or in a single location. If all keys are exposed at once e.g., if they’re all stored on a malware-infected computer), your multi-sig wallet loses its security advantage and becomes as vulnerable as a regular single-key wallet.

Security Auditing tips ✅ Inability to grant proper access control to only verified users for critical functions can expose your smart contract to vulnerability. ✅ Indulge Role-based Access Control (RBAC) fixed on least privilege principle. #solidity #Rust #Solana #Eth

Smart Contracts: Privilege Escalation and Access Control Ensuring appropriate access control, which permits only authorized users to carry out sensitive operations, is one of the most important components of smart contract security. If this is not done, privilege escalation may occur, giving attackers unapproved access to important contract functionalities. Typical Problems with Access Control ** Missing onlyOwner Checks: If important functionalities are not restricted to the contract owner, everyone may be exposed. ** Improper Role-Based Access Control (RBAC): Security flaws can be caused by roles that are too permissive or by permissions that are not specified correctly. ** Exposed Admin Functions: If privileged functions (such upgradeability and pausing) are left exposed, they can be exploited. #Solana
