Sky has been confirmed as the provider of USDS liquidity for FX Layer, the stablecoin exchange system for Spark and Uniswap.
According to Foresight News , Sky (formerly MakerDAO), in conjunction with Spark and Uniswap, announced that approximately $150 million in liquidity migrated from Sky's USDS ecosystem to its previously launched stablecoin FX Layer project. USDS serves as the initial pricing asset within the network, providing basic liquidity for the USDS/USDT and USDS/PYUSD pools. The three parties stated that this is the first large-scale implementation of this liquidity framework, with a long-term vision of enabling more issuers (such as PayPal's continuously expanding PYUSD, Ripple's RLUSD, and institutions like Robinhood and Revolut exploring stablecoin businesses) to access this shared infrastructure, rather than building their own independent liquidity networks. They also aim to explore ways to allow idle funds to generate returns within the governance framework even when not participating in market making. Previously, on June 25, Spark and Uniswap announced the joint launch of the stablecoin exchange system FX Layer, which aims to provide shared liquidity infrastructure for multiple stablecoin issuers such as banks, fintech companies, and payment companies, avoiding the need for them to build their own liquidity pools, market makers, and inventory management. Spark, as the orchestration layer, determines how liquidity is allocated and coordinated among different stablecoins, while Uniswap v4 provides a programmable AMM architecture (a DualPool hook based on hooks mechanism) to execute specific transaction paths.

Uniswap has proposed extending the UNIFication burn program to v4 liquidity pools.
PANews reported on July 8th that, according to Cryptopolitan, Uniswap Labs has proposed extending the UNIfication burn program to Uniswap v4 liquidity pools, requesting UNI holders' approval to charge protocol fees on some v4 pools and use a portion of the revenue to buy back and burn UNI tokens. A snapshot vote will be held from July 7th to 12th, lasting five days. The UNIfication program currently runs on 11 chains, increasing token value by distributing protocol revenue to stakers and burning tokens. If the v4 extension proposal passes, it will further strengthen the deflationary mechanism of the UNI token and may attract more liquidity to the v4 version. The community response has been generally positive, but some smaller liquidity providers are concerned that increased protocol fees may affect their yields.
WEEX Market Observation: Uniswap V4 Hook concept tokens collectively strengthened, with SATO surging over 78% in 24 hours.
According to Mars Finance, on May 21st, WEEX market data showed that the Uniswap V4 Hook concept sector continued its strong performance, with market sentiment significantly improving. SATO led the sector with a 24-hour gain of 78%, currently trading at $0.77127; SLOP and UPEG rose by 32%, currently trading at $1.12 and $957.51 respectively; LOOP gained 31%, currently trading at $1.02. Market analysis suggests that this surge is closely related to the increasing market attention to Uniswap V4's customizable Hook functionality and the overall recovery of the crypto market. The Hook mechanism allows developers to embed custom logic into the transaction lifecycle, providing greater flexibility for liquidity management, fee strategies, and more innovative DeFi scenarios, thus driving investment in related concept tokens. WEEX Labs cautions that most Hook concept projects are still in their early stages of development, and price fluctuations are easily affected by technological advancements, community sentiment, and market liquidity. Users should fully understand the project's fundamentals and the risks of smart contracts before participating, and participate in the market rationally.

Uniswap initiates v4 protocol fee activation temperature check, introducing a tiered fee controller system.
According to official sources, Uniswap Labs has released a temperature check proposal to enable protocol fees in v4 pools. This proposal follows the fast-track governance process previously approved by UNIFication, directly entering a five-day snapshot vote followed by on-chain voting. Because the v4 Hook architecture makes fee setting more complex than v2/v3, the proposal designs a V4 Fee Controller system containing two core contracts: V4FeePolicy calculates fees for any pool based on governance rules, and V4FeeAdapter is responsible for executing governance coverage and collecting fees to the TokenJar. Fees are calculated hierarchically based on the pool's family: first, the fee rate for a specific trading pair set by governance is checked; second, the default fee rate for that family is checked; and finally, the global default fee rate is checked. This proposal aims to activate fees for three types of pool families across 11 chains, including Ethereum, Arbitrum, Base, and BNB Chain: static fee rate pools without Hooks, CCA pools after continuous liquidation auctions, and aggregator Hook pools. The fee rate for the aggregator Hook pool, after a 25x multiplier adjustment, is 10 bp for non-Base chains (3 bp for stablecoin pairs) and 3 bp for Base chains (1 bp for stablecoin pairs). All fees will flow into the TokenJar of each chain. The UNI burning amount on L2 and Alt-L1 will be bridged across chains to the Ethereum mainnet and sent to the 0xdead address. The Snapshot voting window is from July 7th to 12th, and on-chain voting will begin the week of July 13th. Because GovernorBravo limits each proposal to 10 operations, on-chain voting will be submitted in parallel on two chains to cover all chains.
