This issue of Hashingbit features the launch of Ethereum Layer 2 Taiko, new cross-chain standards from Uniswap Labs and Across, the introduction of PayPal USD on Solana, and Fantom's collaboration with Google Cloud. It also covers ZK security advancements for AggLayer and Atoma's AI tools on Sui. Additionally, it includes developer tools for smart contract auditing and Solidity developers, and highlights QuillAuditâs AI agents detecting vulnerabilities in the $NORMIE token.

Hacks and Scams đš
NORMIE
Loss ~ $881K
NORMIE memecoin on the Base network exploited, resulting in a loss of 224.98 ETH (approx. $881,686).
Our QuillShield AI agent detected the same vulnerability in just one second.
Exploit due to a smart contract vulnerability that allowed unauthorized minting of tokens.
Attacker used 2 ETH from Sushi Router to swap for 171,955 NORMIE tokens, then matched the token deployerâs balance by swapping 5 million NORMIE tokens.
Vulnerable _get_premarket_user function added attackerâs address to the premarket user list by matching the team wallet balance.
Flash loan of 11,333,141 NORMIE tokens taken, with 9,066,513 swapped for 65.97 ETH to manipulate token supply.
Remaining tokens used in Uniswap V2 pair and skim function to withdraw assets.
Logic flaws in _transfer and swapAndLiquify functions allowed bypassing checks and minting additional tokens.
Token supply inflated to 650 billion NORMIE tokens; attacker profited 224.98 ETH (approx. $881,686).
Exploiter manipulated contract permissions, used flash loan to drain the contract, bought tokens at no cost, and sold them.
Meta Dragon
Loss ~ $180k
Over 4000 NFTs were compromised in the MetaDragon hack on 28th May 2024, with community members losing approximately 2400 NFTs after deductions for the META fund and marketing.
The NFT contract remains insecure; users are advised to refrain from minting new NFTs.
Significant losses were incurred by community members, investors, and liquidity providers.
MetaDragon plans to compensate each NFT at a rate of "10,000 META + 0.15 BNB".
Total compensation amounts to approximately 24 million META and 360 BNB.
The compensation process will begin gradually with updates provided on progress.
Some partners and major holders have expressed willingness to postpone their claims, prioritizing the compensation of other members, which is deeply appreciated by the MetaDragon team.
