Bitcoin developer and Wizardsardine CEO Kevin Loaec warned that a BTC fork triggered by the BIP-110 proposal could expose users to replay attacks, potentially causing real BTC to be sent when they try to sell coins on the forked chain, CoinDesk reported. Loaec said both chains would accept the same transaction signatures immediately after a fork, and automatic replay protection would not apply. As a result, if a user signs a transaction to sell coins on the forked chain, a third party could submit the same transaction to Bitcoin’s main chain, causing the same amount of BTC to be transferred there as well. He added that ordinary investors who do not know how to safely split assets across the two chains should avoid any on-chain transactions during a fork period. "split" BIP-110 is a proposal to restrict the inclusion of non-payment data such as images and text in Bitcoin transactions. Activation requires support from more than 55% of the most recent 2,016 blocks, or 1,109 blocks, but current miner support is only around 2.6%, meaning the proposal has effectively failed to reach consensus. Even so, from block height 961,632, expected this weekend, BIP-110 nodes are designed to automatically reject blocks without that signal, raising the possibility that the Bitcoin chain could split in two if some nodes continue operating on a separate chain.

Polymarket will shift its settlement method to a time-weighted average price, or TWAP, to curb artificial price swings, CoinDesk reported. The platform decided to replace the single price snapshot method used in short-term crypto markets with TWAP. Earlier, researchers at Stanford University in the U.S. and Singapore Management University said an analysis of five-minute Bitcoin contracts found a pattern in which large trades hit Binance in the final seconds before settlement, moved prices, and were followed by settlement. They added that prices repeatedly snapped back to prior levels shortly after unusual large trades on Binance caused the moves. Polymarket said it made the change in response to the findings and continued complaints from traders.

U.S. Senate Republican leader John Thune’s office has told industry participants it still may file cloture to begin Senate consideration of the CLARITY Act before the August congressional recess, according to Crypto in America host Eleanor Terrett. Terrett said the move would help lay the groundwork for a September vote on the CLARITY Act and signals Republican leadership intends to prioritize the bill once the Senate returns. Still, the effort requires securing votes that are not yet in hand, resolving differences over yield-related issues, and reaching agreement on bipartisan ethics provisions.

Sen. Angela Alsobrooks said lawmakers will keep working toward passing the CLARITY Act properly after the U.S. Senate delayed a vote on the bill until September. Alsobrooks said more than a year of bipartisan cooperation has been focused on reaching a fair agreement on consumer protection, preventing deposit outflows, curbing illicit finance and addressing ethics issues, adding that the goal remains to pass the CLARITY Act properly.

BitMEX said it will shut down exchange operations at 4:00 a.m. UTC on Sept. 23, while the platform spent the past two years in sale talks with potential buyers including rival exchanges and payments platform Exodus but failed to reach a deal, CoinDesk reported. According to the report, negotiations were hindered by efforts to preserve the founders' control, the company’s past negative image, and slowing growth. An industry source who requested anonymity said potential buyers were uncomfortable that co-founders Arthur Hayes, Ben Delo and Samuel Reed had stepped back from the business after being criminally charged in the U.S. in 2020 but still controlled a significant portion of the company’s equity. The sale process is said to have targeted a roughly $1 billion valuation, though it was not confirmed whether any formal bid proposals were submitted.

U.S. Republican Senator Cynthia Lummis, a leading pro-crypto lawmaker, said efforts to advance the CLARITY bill would not stop and the fight over crypto legislation was far from over. The comment came after the Senate earlier decided to delay a vote on the CLARITY bill until September.

The U.S. Treasury Department’s Office of Foreign Assets Control sanctioned Iranian cryptocurrency exchanges Shelbit and Aban Tether, saying they had supported funding for Iran’s Islamic Revolutionary Guard Corps and facilitated illicit finance.

Bybit has filed a civil lawsuit against North Korea, its Reconnaissance General Bureau (RGB), and the Lazarus Group over last year’s $1.5 billion hack, CoinDesk reported. The exchange filed the case in the U.S. District Court for the District of Columbia and also secured a preliminary injunction barring the transfer or disposal of certain assets tied to the incident while the case is underway, according to CoinDesk. Bybit CEO Ben Zhou said, "Our goal is to put user protection first, recover as much as possible, and hold accountable those behind these attacks." Zhou added, "The Lazarus attack was not simply an attack on Bybit. It was an attack that shook trust in our industry." He said Bybit has worked closely with investigators, exchanges, regulators, judicial authorities and now the court, and plans to seek additional relief. The civil case is proceeding separately from an ongoing criminal investigation by U.S. law enforcement authorities, the report said. The Lazarus Group stole about $1.5 billion worth of Ethereum from Bybit in February last year.

Coinbase CEO Brian Armstrong said on X the Senate did not take up the CLARITY bill this week, calling the outcome disappointing while expressing gratitude and backing Senate Majority Leader John Thune’s pledge to bring the bill forward in September. Armstrong added that interest in the technology continues to grow regardless of the congressional calendar, Congress has an important role to play, and voters are closely watching who helps and who blocks the bill’s passage. He said the effort is closer than ever to its goal and urged lawmakers to finish the bill in September.

Open-source crypto payment processor BTCPay Server warned an active exploit targeting a discovered vulnerability is under way and could lead to fund losses.

Galaxy Research said an estimated 1,719 BTC has been stolen so far in the Coldcard incident, with losses likely exceeding $130 million. More than 250 cases have been reported so far, and Galaxy Research added the total could expand to more than 2,300 BTC if all cases are ultimately confirmed.

Blockaid CEO Ido Ben-Natan said the Coldcard vulnerability incident exposed a structural weakness in crypto’s reliance on private keys, The Block reported. Ben-Natan said systems built around private keys can ultimately create a single point of failure. He added that the Coldcard case was particularly shocking because the wallet was designed to keep private keys offline and separated from the internet, yet hackers exploited a flaw in which Coldcard devices did not generate sufficient randomness during wallet seed creation. Ben-Natan said simply storing assets somewhere and forgetting about them is not a real solution, as the security landscape changes very quickly. He stressed that users must either remain continuously vigilant or delegate security decisions to specialized institutions.

Bitcoin wallet activity surged without a corresponding rise in inflows to major exchanges following the Coldcard hack, according to UBC Blockchain, citing Santiment data. As of July 31, local time, Bitcoin active addresses stood at 978,000, about 1.6 times the July average. From Aug. 1 to 6, daily average active addresses were around 720,000, above July’s roughly 610,000. By contrast, average daily inflows to exchanges from Aug. 1 to 6 were about $1.55 billion, below July’s average of about $1.67 billion. UBC Blockchain said, "콜드카드 해킹으로 인해 주요 거래소로의 자금 유입 없이 비트코인 월렛 활동이 급증했다."
