Polygon disclosed multiple previously undisclosed security vulnerabilities that were recently fixed through two hard forks, which could affect its proof-of-stake network. The vulnerabilities involve Polygon's Bor and Heimdall clients, including denial of service risks, validator resource exhaustion, and defects affecting checkpoint and milestone processing.Polygon stated that these vulnerabilities were fixed through the Austin and Kyoto hard forks, and the fixes were privately tested before being deployed to the mainnet and publicly disclosed. The most serious issue involved Heimdall, where a carefully crafted transaction could force validators to perform excessive processing work, thereby disrupting the network. The Austin hard fork also fixed two denial of service risks in Bor that could slow down block processing or cause node crashes.Polygon indicated that these vulnerabilities were not exploited on the mainnet, and the fixes were proactively deployed before the details were made public. Nodes running outdated client versions have fallen out of consensus after the hard fork activation height and must upgrade to rejoin the standard network. All Polygon PoS nodes are required to upgrade to Bor v2.1.0, and validators and full nodes must upgrade to Heimdall v0.11.0, both upgrades are now effective on the mainnet.

Cosmos Labs released a technical report, admitting that it previously misjudged an integer underflow vulnerability in the Cosmos EVM, which led to attacks on six blockchain networks between August 20 and 25, resulting in a total theft of approximately $5.7 million in tokens. The attacker exploited the vulnerability to underflow account balances to the maximum value of 2^256-1, then performed a reverse operation to transfer the inflated balance out, thereby stealing tokens from the target accounts without creating tokens out of thin air.The report shows that researchers submitted the defect through a bug bounty program on April 25, but testers were unable to reproduce it on the existing Cosmos chain configuration, so Cosmos Labs silently patched it in May. Independent researchers confirmed in early August that the vulnerability affected all Cosmos EVM chains, and Cosmos Labs released a patch on August 19, but the first attack occurred about 20 hours later.In terms of specific losses, MANTRA lost 720.9 million tokens (approximately $3.6 million), TAC lost nearly 3 billion TAC, and KiiChain lost about 148 million KII. Both MANTRA and KiiChain criticized Cosmos Labs for not notifying the affected chains in advance and suggesting a shutdown, with KiiChain stating that the patch would take several days to deploy while a shutdown would only take a few minutes. Cosmos Labs stated that it has coordinated responses with 40 chains and assisted 13 chains in completing repairs or shutdowns before being attacked.

CryptoQuant analyst Darkfost stated that the inflow of Bitcoin to exchanges has surged sharply in the past 7 days, peaking as BTC attempted to break through the $80,000 mark. Binance led with an average daily inflow of 10,700 BTC, followed by Coinbase Advanced with an average of 7,100 BTC, and both Kraken and OKX exceeding 2,000 BTC.He pointed out that $80,000 represents the average cost basis for all capital invested in BTC and is a critical breakeven point, where many investors choose to lock in small profits or stop losses. As the BTC price pulls back, selling pressure is weakening, and if the selling pressure continues to ease, Bitcoin may soon test this resistance level again.

Liquid Capital founder Jack Yi stated on the X platform: "As expected, there has been a slight pullback. If it continues to pull back to around $75,500, it will be a great new opportunity, and I remain optimistic about the rise after the slight pullback. Investing and trading are the hardest things. I entered the mining circle in 2015 at a low BTC price and later successfully invested in Quantum and others, catching the crazy bull market of 2017. This was entirely a matter of luck, but at the time, I thought it was skill, as I had previously achieved some success in entrepreneurship and investment in classical industries.Later, I crazily invested in hundreds of projects, most of which failed and a few succeeded. As investment opportunities decreased, I began to work hard on learning trading, which requires even more respect. I succeeded in trading nine times in a row, but the tenth failure brings me back to square one."

According to The Defiant, oracle provider RedStone reports that tokenized RWA assets on the Stellar chain surpassed $3 billion in July, a significant increase from $785 million in January, while the total locked value in DeFi is only $213 million. The lending protocol Blend holds $127 million, and the pool accepting RWA as collateral is just over $2 million, indicating that RWA issuance has outpaced on-chain availability.The growth is primarily driven by four products: Amundi and Spiko overnight swap fund ($713 million), Spiko T-Bill fund ($536 million), Ondo USDY (over $533 million), and VuMe Bond 2030 ($500 million). RedStone points out that the settlement cycle of RWA does not match the 24/7 on-chain lending market, and the pricing mechanism is the current main bottleneck. Stellar already has 55 SEP-40 price data sources provided by RedStone. RedStone also mentioned that DTCC plans to bring its $114 trillion in custodial assets to Stellar by 2027.
