@HackenProof Classic CEI violation leading to Reentrancy...
_safeMint triggers an external call before updating usedPass[msg.sender] = true;. An attacker can re-enter and bypass the single-use check completely.....

[Chain Shield @DeFiAudit]

My latest Web3 audit:

🎯 5 Dups (radar works, speed doesn't).
❌ 2 Rejected (I see a flaw, devs see "defensive design").
💰 Payout: $0 & a headache.

Bug bounty is a masterclass in humility. We go again! 🛡️

#BugBounty #Web3Security

[Chain Shield @DeFiAudit]

Nothing tests your sanity like 5 Duplicates on a massively complex project. 🤯
I almost gave up. But when the easy bugs are gone, you look at the math. Found a fatal time-logic flaw and pulled 2 NEW bugs 🕵️‍♂️⚡
Keep digging.
#SmartContracts #BugBounty

Let's wait for the result.

@xKeywordx @immunefi I was banned from this platform because I reported six duplicate vulnerabilities..
What sin have I committed?

[Chain Shield @DeFiAudit]

@MitchellAmador Huge milestone! Losing a report to an empty duplicate is frustrating. My high-severity report was closed & triggered an SNR autoban, despite a functional Mainnet-forked PoC for exact economic extraction. Eager for manual review to test this new era!

Echo Protocol was hacked for $76M, but the attacker only cashed out $820K. Why? Zero exit liquidity. You can mint infinite unbacked tokens, but you can't drain what isn't there.
The real tragedy? No Timelocks or Mint Caps. Don't build Web3 on Web2 security. 🛡️💻 #DeFi

@pawel_research Not dumb, just no exit liquidity. You can mint $76M from thin air, but you only drain the actual TVL in pools. The real tragedy? Missing basic on-chain guards: no Timelocks, no Mint Caps. A complete architecture failure

@arshadkazmi42 @Hacker0x01 Platforms are drowning in AI spam, while researchers building functional Mainnet-fork PoCs pay the price—often facing unfair SNR autobans. Bounties must reward actual proof, not who clicked submit first. Great tip on tracking NA duplicates!

[Chain Shield @DeFiAudit]

@VagnerAndrei98 @immunefi 100% agreed. The disconnect between protocol specs and platform triage is a real issue. I just got hit with a strict SNR autoban immediately after a report closure, despite providing a fully functional Mainnet-forked PoC demonstrating exact economic extraction..good work

Always enforce strict slippage parameters at the protocol level. 🛠️🛡️ #Solana #DeFi #SmartContractAudit

[Chain Shield @DeFiAudit]

A reminder for DeFi developers: Relying on the frontend for slippage protection is NOT enough. If your smart contract lacks an explicit min_lamports_out guard during liquidity withdrawals, it leaves users completely exposed to MEV sandwich attacks on-chain.

@claimyshare Est-ce vraiment nécessaire d'avoir autant de temps ?

@AtpHassan @idOS_network @idos We'll see how things change after them.

@chameleon_jeff That’s exactly why Hyperliquid stands out it delivers what blockchain truly promised: verifiable transparency, not blind trust.
CEXs still sell "trust" as a feature instead of proving it onchain.

Hackers don’t just exploit code… they exploit human nature.
Stay sharp. Stay skeptical. Protect your assets.

In crypto hackers don’t always attack the code..
Sometimes they attack you..
This is called Social Engineering the art of exploiting human psychology..
