Uniswap initiates a temperature check for the activation of v4 protocol fees, introducing a tiered fee controller system

According to official news, Uniswap Labs has released a temperature check proposal, suggesting the activation of protocol fees in the v4 pool. This proposal follows the rapid governance process previously approved by UNIfication and will directly enter a five-day Snapshot voting period, followed by on-chain voting.Due to the Hook architecture of v4 making fee settings more complex than v2/v3, the proposal has designed the V4 Fee Controller system, which includes two core contracts: V4FeePolicy calculates the fees for any pool based on governance rules, and V4FeeAdapter is responsible for executing governance overrides and collecting fees into TokenJar. Fees are calculated hierarchically based on the family of the pool: first checking the specific trading pair rate set by governance, then the family default rate, and finally the global default rate.This proposal aims to activate fees for three types of pool families across 11 chains including Ethereum, Arbitrum, Base, and BNB Chain: static rate pools without Hooks, CCA pools after continuous liquidation auctions, and aggregator Hook pools. The rates for aggregator Hook pools are adjusted by a 25x multiplier, with a default of 10 bp for non-Base chains (3 bp for stablecoin pairs) and a default of 3 bp for Base chains (1 bp for stablecoin pairs). All fees will flow into each chain's TokenJar, and the amount of UNI burned on L2 and Alt-L1 will be cross-chain bridged to the Ethereum mainnet and sent to the 0xdead address.The Snapshot voting window is from July 7 to July 12, and on-chain voting will start during the week of July 13. Since GovernorBravo limits each proposal to 10 actions, two on-chain votes will be submitted in parallel to cover all chains.

Zhao Changpeng: We are no longer operating the trading platform; BNB Chain is developing a new version that is faster, cheaper, and has more privacy controls

Binance founder Zhao Changpeng (CZ) participated in an exclusive interview on the Galaxy Brains podcast with Galaxy Research Director Alex Thorn. CZ stated that he is no longer operating the trading platform, allowing him more time to communicate with developers, and he is excited about some new features of BNB Chain. He mentioned that BNB Chain is developing the next version, which will be faster, cheaper, and include more privacy controls.CZ also advised blockchain developers not to make major upgrades during a bull market, but to push forward significant updates during the quieter times of a bear market. CZ said that he was skeptical about RWA (Real World Assets) about a year to a year and a half ago, uncertain whether the related assets would be traded or could develop. However, the speed of RWA's development surprised him, as stablecoins, oil futures, AI stocks, and others have gained good acceptance in the crypto community. This indicates that many people globally have been looking for access to these assets.Crypto should not be seen as an independent industry, but rather as a new technological tool that makes financial transactions faster, cheaper, and more transparent. He believes that traditional financial institutions can use blockchain, and crypto companies can also provide services similar to traditional finance, such as loans, savings, stock trading, remittances, and payments. In the future, there should not be a clear distinction between traditional finance and crypto, but rather a more globalized, faster, and lower-cost financial industry.

Analysis: Anthropic refuses to fix the Fable jailbreak vulnerability, leading the U.S. government to implement export controls

David Sacks, the head of AI and crypto affairs at the White House, stated that although the commercial version of the Mythos series model Fable released by Anthropic this week includes safety barriers, once those barriers are bypassed, users will be able to access Mythos's advanced cyber attack capabilities. Sacks pointed out that Anthropic had previously described Mythos as a "cyber weapon" that requires regulation, so fixing the related vulnerabilities should have been its responsibility.Sacks mentioned that a partner trusted by both Anthropic and the U.S. government discovered a jailbreak method to bypass the safety barriers while testing Fable. The U.S. government subsequently requested Anthropic CEO Dario Amodei to fix the vulnerabilities or take the model offline, but this request was refused. Anthropic stated in a declaration that the vulnerability is "not serious," a claim that contradicts the judgment of the U.S. government and relevant partners.Sacks stated that Anthropic has always emphasized that safety should be prioritized, but this time it prioritized maintaining consumer-grade model services. In response, the U.S. government reluctantly imposed export control measures on Anthropic and hopes that Anthropic will resolve the safety issues as soon as possible to lift the related restrictions and restore the full release of Fable.Sacks also denied that this action is related to previous disputes between the U.S. Department of Defense and Anthropic, stating that the government recognizes Anthropic's technological capabilities and believes that the current issues can be resolved relatively easily, with the initiative currently in Anthropic's hands.

After 14 years, Bitcoin addresses from the Satoshi Nakamoto era have shown activity, and some dormant wallets may still be controlled by their original owners

According to CoinDesk, an address from the "Satoshi era" that has never been used since March 2011, holding 35.55 bitcoins (approximately $2.54 million), made a transfer this week, which is seen as one of the first publicly visible responses from defendants in a lawsuit involving approximately 3.8 million bitcoins (valued at about $285 billion) in New York.On-chain data shows that the address transferred 15 BTC to a new address on June 2, keeping the remaining 20.55 BTC as change. The address initially received bitcoins on March 27, 2011, when the price of BTC was less than $1.In March of this year, a plaintiff using the pseudonym "Noah Doe" filed a lawsuit in New York state court alongside two LLCs from Wyoming, attempting to claim ownership of approximately 3.8 million long-dormant bitcoin wallets under New York's lost property law, positioning themselves as the "discoverer." The court approved sending on-chain notifications to the relevant wallets via the bitcoin OP_RETURN field.In July 2025, the advisory firm Salomon Brothers Strategic Advisors sent dust transactions with links to legal notices to 39,000 wallets, including the aforementioned address, requesting holders to prove ownership within 90 days.Alex Thorn, head of research at Galaxy Research, pointed out that the address corresponds to defendant number 38215 in the case, stating, "Clearly, these bitcoins have not actually been abandoned."Additionally, another address that had been dormant for 15 years, 1CDSyXAQxro4FPUoqAQb81642ruqDsUiNp, also transferred 20 BTC (approximately $1.48 million) on the same day, but this address did not appear on Noah Doe's list of lawsuits.Analysis suggests that the on-chain movements mentioned above indicate that some bitcoins from the Satoshi era, considered "abandoned assets," are actually still under the control of the original holders.
