And make sure to audit 'em! You wouldn't buy a car without checking it first, right? Same thing. Safety first, folks! #CryptoAudit 🕵️‍♂️🔍

Secure your smart contracts, bros! Multiple devs should agree on upgrades. Don't let one bad apple spoil the whole barrel. #CryptoWisdom 🧙‍♂️🔮

[Mo Ashouri, PhD @ashourics]

That's what can happen with insecure upgradable smart contracts. A bad actor could 'upgrade' the contract to scam users. #CryptoScams🚫

[Mo Ashouri, PhD @ashourics]

Imagine a smart contract like a vending machine. You put in a coin (ETH), and get a candy (token). But what if some jerk changed the machine to give rocks instead? #NotMyCandy 🍬💔

[Mo Ashouri, PhD @ashourics]

But, fam, every coin has two sides. They can be insecure. Hackers can exploit 'em. Not cool, right? That's why we gotta talk 'bout it. #CryptoSecurity🔒

[Mo Ashouri, PhD @ashourics]

First, what's an upgradable smart contract? It's a contract we can change after it's live. Like upgrading an app, but for crypto. Ain't that cool? 😎💡 #CryptoUpgrades

[Mo Ashouri, PhD @ashourics]

#CryptoCommunity! It's @ashourics talkin' 'bout something big today. Insecure upgradable smart contracts in Ethereum. Hold onto your hats, pals. We're diving deep! #Ethereum #SmartContracts 🚀

By default, the Rust compiler does not generate optimized binaries, which is vital for the wide spectrum of applications. In this video, I show you some tips and tricks to optimize your binaries in Rust.

Before releasing your Rust code, always fuzz it, why do not you use cargo fuzz?

[Mo Ashouri, PhD @ashourics]

Fuzzing help to extract tricky bugs that often you cannot find them by doing a normal code audit. This is specially critical for DeFi smart contracts. In my YouTube channel I posted a video explaining how to perform fuzzing for Solidity contracts:

How to protect yourself against unlimited tokens approval hacks?
3- If you already have open approves for a variety of dApp, consider revoking them with tools like:

How to protect yourself against unlimited tokens approval hacks?
2- Some wallets (e.g., MetaMask) allow edit the approved amount. So consider only allowing it to use the amount you would like to risk.

How to protect yourself against unlimited tokens approval hacks?
1- Do your own research when interacting with an unknown or even well-known dApps ! some users have lost their funds by staking or swapping their tokens !
