I want to pinned this here I promised by this time next year my life will be so much more better as smart contract developer and security researcher.

@moonpay @KeyboardCatBase x.com/i/status/20423…

@KeyboardCatBase your KEYCAT was delivered

$KEYCAT coded.

@PatrickAlphaC 🤣🤣 i love this man

Putting this here for no reason

@moonpay How about me @moonpay I am learning web3 security my computer got broken saved smoe cash but still short i will buy a good computer and keep working on making Crypto safe.

the giveaway wallet got refilled

@Learnernoearner Thanks you for providing free signal and giveaway may God reward you

200$ giveaway Thank you for being here Comment smth nice will pick winner in couple hours

Day 32 of becoming a Smart Contract Developer🔥 Just Completed My foundry Course Today🎉. It's been Exciting and Challenging. Today i Learnt: ✅Forked Test Environment ✅Learnt How to Deploy the contract on a testnet Thanks @CyfrinUpdraft #web3 #solidity #Foundry

@xKeywordx Congratulations broo

I, FINALLY, broke the ice. I hoped for at least Medium here, but I'll take this as a first BB win.

@Surlymarn Am telling you explore b4 u die

God abeg make i no kpai for "Rimin kebe" @uptown_crypto 😭😭

@0xZulkifilu I learn this on tuesday ✅

✅ QUIZ #6 ANSWER — C) The transaction reverts Solidity 0.8.0+ reverts on overflow with Panic(0x11). uint8 max = 255. 255 + 1 overflows uint8 → revert. For wrap-around behaviour in 0.8.0+: 👇 Pre-0.8.0: answer was B (silent wraparound). This was the biggest 0.8.0 breaking change — SafeMath libraries are no longer needed.

SOLIDITY QUIZ #6 What is the value of x after calling increment()? A) 256 B) 0 C) The transaction reverts D) Compiler error Reply + explain why 👇Full answer in 24 hrs in comment section. Solidity quiz will keep coming daily, my goal is to make sure every developer and auditor benefit from it.

@0zpan @HackenProof Congratulations

Grinding #Web3security

🔓 YESTERDAY'S BUG — REVEALED. The vulnerability: integer overflow in increaseLockTime(). function increaseLockTime(uint256 secondsToAdd) external { lockTime[msg.sender] += secondsToAdd; } In Solidity below 0.8.0, uint256 arithmetic wraps silently on overflow. An attacker exploits this to escape their time lock early: Attack sequence: 1. User deposits. lockTime[attacker] = block.timestamp + 1 weeks (roughly: 1,700,000,000 + 604,800 = 1,700,604,800) 2. Attacker calls increaseLockTime with: secondsToAdd = type(uint256).max - lockTime[attacker] + 1 3. lockTime[attacker] overflows and wraps to 0 4. withdraw() checks: block.timestamp > 0 — TRUE 5. Attacker withdraws immediately, before their lock expires This is an Ethernaut Level 15 challenge — it has caught many experienced developers off guard because the function name sounds protective. "Increasing" the lock sounds safe. But the arithmetic has no ceiling. FIXED FUNCTION: 👇 This is why arithmetic boundaries always deserve explicit scrutiny — especially in functions users can call themselves.

@immunefi @Ehsan1579 Congratulations @Ehsan1579

Security researcher @Ehsan1579 just brought home $300,000 from a critical report via Immunefi. He's absolutely on fire in 2026. If you pledge $IMU behind him, you both earn $IMU when he finds more bugs: immunefi.com/pledge/bpop232…

$1M+ milestone ✅ just in 90 days, bro is absolute beast & web3sec gem.. he is just getting started ig, 9months left i think $5M+ by the year end?

I want to share something honestly in my early days, the one and only person I was learning from was @PatrickAlphaC He’s incredibly smart, highly credible, and truly one of the most legit people in the space. If you don’t know him yet, then you’re seriously missing one of the best voices in Web3. If you’re looking for someone solid to learn from, he’s absolutely one of the best, especially if you’re a developer or you want to be.

@justice95441214 @icekied @NigeriaStories But this is single birth no matter how rich you're you have no power over this 🤷‍♀️ unless you want to kill the whole pregnancy

@icekied @NigeriaStories Was about asking same thing. Why always the poor?

BREAKING NEWS: A woman, Hafsatu Yusuf, has given birth to quintuplets at the Murtala Muhammad Specialist Hospital, Kano, with the state government assuming responsibility for their medical care.

@DhanushK1271650 @PatrickAlphaC @CyfrinUpdraft Congratulations bro

wrote my first ever smart contract today woohooo!!! thnx @PatrickAlphaC @CyfrinUpdraft

@hamidonsolo Alhamdulillah may Allah see us through and may Allah bless you for this exceptional help you're doing for free
