The project was audited by SolidProof and InterFi. The project announced that they intended to relaunch the token, and asked the exploiter to consider returning 80% of the funds, keeping 20% as a "bug bounty".
Uwerx crypto-based freelancer platform exploited
Uwerx is a nascent project intending to build a blockchain-based freelancer marketplace, because what better concepts to combine than blockchains and the gig economy? Sadly for them, just after completing their token presale, it was hit with a flash loan exploit that enabled an attacker to siphon 176 ETH (~$324,000) from the platform.
LeetSwap exploited on Base
Although Coinbase's Base blockchain is at this stage intended for testing only, people have begun bridging substantial assets to the platform and using various services in anticipation of its official launch.
One such service is LeetSwap, which describes itself as the "The #1 DEX ecosystem for elite degens built on the leetest blockchains", and which recently launched its service on Base. On August 1, LeetSwap was exploited after an attacker discovered a function that allowed them to manipulate token prices on the project for a profit of around 342 ETH (~$624,000).
LeetSwap attempted to contact the hacker via social media, asking them to return all but 50 ETH (~$92,000, or around 15% of the stolen funds).
Phisher briefly snags $20 million before it's frozen by Tether
A zero-transfer attack, also called an address poisoning attack, occurs when a phisher creates a blockchain address very similar to that of a target victim's wallet, and sends zero-value token transactions to the victim's addresses from the phishing wallet in hopes that the victim will later mistake the phishing address for the real one and send funds to it. It sounds unlikely to work, but users often fail to verify every character of the destination address they're using, opting instead to copy it from their transaction histories, and this can profit scammers substantially.
Someone intending to transfer Tether stablecoins amounting to $20 million apparently didn't think it was important to double-check the address, and fell for such an attack.
However, only 51 minutes after the theft, the victim had managed to get Tether to add the thief's address to its blacklist, freezing the assets and thwarting the attack. The rapidity of the freeze led various people to question who the victim might be who could get Tether to intervene so quickly.

BALD memecoin plunges after $25.6 million rug pull
A memecoin called $BALD, built on the Coinbase Base test network, appears to have rug pulled for at least $25.6 million. Although the Base network is meant to be used for developer testing, some people have tried to trade on the network before its official launch.
A pseudonymous crypto user called "Bald" announced that they would be selling $BALD tokens on the Base network, and the token — apparently named after the hairless Coinbase CEO Brian Armstrong — quickly skyrocketed in price. However, the token deployer emptied tokens priced at around $25.6 million from the liquidity pool two days after launch in apparent rug pull. The token price quickly plunged by around 90%.
Conspiracy theories emerged that the Bald account was in fact operated by Sam Bankman-Fried, the former CEO of FTX who is on house arrest under strict supervision and without access to most websites as he awaits trial later this year.
SEC goes after Richard Heart and his projects Hex, PulseChain, and PulseX
The SEC filed charges against Richard Heart, the operator of Hex, PulseChain, and PulseX. Despite Heart's best attempts at evading securities laws — including by asking people to "sacrifice" tokens in exchange for PLS and PLSX to avoid using the term "invest" — the SEC says he's been conducting unregistered securities offerings amounting to more than $1 billion.
In addition to the unregistered offerings charge, the SEC alleges Heart and PulseChain misappropriated $12.1 million to fund Heart's lavish lifestyle. Among other things, he purchased a McLaren sports car, five luxury watches, and a $4.3 million 555-carat black diamond called "Enigma", allegedly using funds from the sale.
Bug in Vyper smart contract language enables multiple exploits on Curve and related projects
Some types of Curve factory pools, including one operated by AlchemixFi and one by JPEG'd, were exploited. The attack stemmed from an issue in the Vyper language, a smart contract programming language that is similar to Solidity. Early investigations suggested that versions of the Vyper compiler had improperly implemented a re-entrancy guard, leaving some projects vulnerable to that type of attack. Vyper tweeted an announcement that the versions were vulnerable, and urged "projects relying on these versions [to] immediately reach out to us".
Curve itself lost $61 million to the exploit. AlchemixFi was exploited for around $13 million in assets, and JPEG'd suffered a $11 million loss. MetronomeDAO suffered a $1.6 million loss, Ellipsis Finance lost $68,600, and Debridge Finance lost around $24,600.
Altogether, somewhere between $88 million and $100 million was taken, though some exploits appeared to be whitehat actions intended to preserve funds. The primary exploiter also later returned some of the stolen funds, refunding the entire amount to AlchemixFi and 90% of funds to JPEG'd in exchange for a 10% "bug bounty".
Kannagi Finance rug pulls for over $2 million
The defi yield aggregator project Kannagi Finance rug pulled on July 29 as its creators drained the $2.13 million total value locked. Kannagi Finance deleted its website and social media accounts following the exit scam.
Blockchain security firm SolidProof had audited Kannagi in June.
Memecoin launch by Pauly0x costs traders at least $2.2 million
Traders hoping to get in on the next big memecoin eagerly snapped up a token called Pond0x, a Pepe the Frog-branded memecoin launched by Pauly0x. Pauly0x is Jeremy Cahen, a crypto personality best known for his creation of CryptoPhunks, NotLarvaLabs, and involvement in the Ryder Ripps lawsuit.
However, serious flaws in the Pond0x contract resulted in traders losing at least $2.2 million as people discovered that anyone could transfer coins belonging to other people. People quickly began rushing to steal coins from one another.
Pauly0x responded by blaming the traders who bought and sold the tokens, and spent the following day variously posting on Twitter that he was teaching people a lesson, that it wasn't his fault that people lost money, and suggesting that the flaw was part of a bigger plan for the project. "No one stole your tokens lol. The contract is literally designed as such," he wrote to angry traders accusing him of a rug pull. He added to the website a message reading, "GREED KILLS".
DeFiLabs rug pulls for $1.6 million
A defi project called DeFiLabs was able to rug pull for $1.6 million thanks to a backdoor written into the smart contract. After traders bought into the project, its creator was able to call the
withdrawFunds function to make off with the project's assets.DeFiLabs claimed on Twitter that the platform "encountered an unexpected issue" while "undergoing maintenance and updates".
DeFiLabs had been audited by blockchain security firm CertiK.

CoinsPaid hacked for $37.3 million
The CoinsPaid crypto payment platform, which provides payment services to various online casinos, reportedly suspended withdrawals under mysterious circumstances. The company later deleted a handful of tweets pertaining to the incident, which they ascribed to a "technical issue".
After prominent Bitcoiner Jameson Lopp tweeted that the issue "look[s] more like a hack", CoinsPaid replied "Our team is aware of the issue... Please wait for the official announcement on this topic." Crypto researcher zachxbt responded, "The issue is you got hacked by North Korea that's what lol", referencing the increasing suspicion that the Lazarus group may be behind the disruption. Sure enough, CoinsPaid later confirmed that they had been hacked for $37.3 million, and announced that they suspected the Lazarus Group was behind it.
Some have been speculating that there are connections between this incident and the $60 million hack of the Alphapo crypto payments processor on July 22. Alphapo also provided services to various online casinos. Indeed, there seem to be connections between Alphapo and CoinsPaid, and they may in fact be operated by the same people.
