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

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

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

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.

GM I discovered that we don't have so many DevOps engineers migrating to the Web3 space. I've been wondering if there's no enabling environment of they don't know the goldmine in it. Blockchain Security and Web3 DevOps is the new gold mine that is well gated.

GM I just passed the Certification: Chainlink Fundamentals exam on @CyfrinUpdraft ! updraft.cyfrin.io/courses/chainl… Big thanks to @PatrickAlphaC for the good job he's doing with this course. My first certification in web3 security

GM Chainlink data stream can perform magic with off chain interface for real time data. Almost done with Chainlink fundamentals. It's been a sweet journey altogether.

So you just got a new PC for your work or home use, why go for the manual way of installing packages? When you can simply automate the development setup installation of Rust, Git, Foundry, Hard hat etc Automation is key to avoid time wasting. #Solidity #Rust #Foundry

GM "Like Cortes you must locate the root of your problem. It is not the people around you; it is yourself, and the spirit with which you face the world." Chase Web3 security with your body and soul, there will be a big reward for staying true to the grind. #Solidity #Rust #Bugbounty

GM I'm not resting on my Tech Journey so I will be running a 50 days study trip to revisit Core DevOps concepts so I can shoot for DevOps roles in the Web3 sphere. I will be doing this alongside the Blockchain security course I started with @CyfrinUpdraft Expecting a burnout soon 😔

Day18/1001 with @cantinaxyz and @CyfrinUpdraft course. Best practice for beginners Indulging credible security auditors is essential for your contract, this helps checkmate against vulnerability that will be unnoticed during development phase. Keeping it real.

I deployed a basic Counter Contract on Sepolia testnet. Then i did the Chainlink automation upkeep to spin up the event every 15 mins with a Cron job scheduler on Time-Based automation process. grinding with @CyfrinUpdraft #Solidity #Web3 #Blockchain #Chainlink

Best practice while using Chainlink Automation. ** Implement essential authorization while using access Control feature like "Ownable" or indulge Role-based Access control mechanism to restrict sensitive functions to only authorized users. Always uphold the sole principle of least principle. #Solidity

GM GM Please remember not to make the beginner's mistake by hard coding your essential values like addresses. Use constructor parameters, constants, or configs. Such that you can adjust them when needed without redeploying everything to your remote Repo. This is for Blockchain developers.
