first_img Uniswap launched StablePair Hook, a dynamic fee rate to help LP capture the value of stablecoin transactions

According to The Block, Uniswap Labs announced the launch of a new tool, StablePair Hook, designed specifically for stablecoin trading pairs such as USDC/USDT and USDC/USDG.Uniswap Labs stated that StablePair Hook can provide traders with consistent and predictable quotes, allowing liquidity providers to retain more of the value they create. Data shows that in the second quarter, the trading volume of exchanges between stablecoins on Uniswap reached $43.4 billion, surpassing the total of the other three major on-chain trading venues.StablePair Hook replaces fixed rates with dynamic rates, which adjust based on the degree of price deviation from the reference price within the pool. When the price is close to the reference price, the Hook adjusts the transaction fee for each trade to maintain a fixed bid-ask spread; when the price deviates from the reference range, trades that push the price away incur no fees, while trades that pull the price back to the reference price use a Dutch auction mechanism, with fees decreasing block by block from high to low until accepted by the trader. Uniswap Labs stated that this allows liquidity providers to retain more value from price returns.The first batch of StablePair Hook pools will go live on Ethereum, supporting USDC/USDG and USDC/USDT trading pairs. This Hook can be upgraded through Uniswap governance, and the fee system and other parameters can be adjusted without migrating liquidity.

Former Deputy Governor of the Bank of England Jon Cunliffe has joined blockchain payment company Fnality and serves as the Chairman of the UK entity

According to Bloomberg, Jon Cunliffe, the former Deputy Governor for Financial Stability of the Bank of England, has joined the blockchain payment company Fnality and will serve as the Chairman of its UK entity. Jochen Metzger, the former Director General for Payment and Settlement Systems of the German central bank, has been appointed as a member of the Supervisory Board of Fnality Europe and is expected to serve as its Chairman; Ron Berndsen, the former Head of Supervision and Head of Market Infrastructure Policy at the Dutch central bank, will also join the Supervisory Board.Fnality operates a wholesale payment system that allows banks to settle debts using central bank currency balances. Its pound sterling system, regulated by the Bank of England, went live in 2023 and is currently seeking regulatory approval to launch versions in US dollars and euros. Fnality states that the system is designed to support the tokenized trading of traditional assets such as stocks and bonds, enabling the synchronized flow of securities and payment funds across interconnected digital networks, thereby shortening settlement times and supporting round-the-clock trading. Fnality was established in 2019, with investors including major financial institutions such as Goldman Sachs, UBS Group, Santander Bank, Bank of America, and Citigroup.

Arthur Hayes released the FLOP yellow paper, planning to airdrop all tokens

Arthur Hayes released a new project FLOP white paper on social media. FLOP is a proof of useful inference (PoUI) blockchain and native currency aimed at the agent economy, where AI agents can use FLOP to pay miners for inference fees. The network adopts an architecture that combines PoUI with account-based chains, where agents submit session requests to the memory pool containing model weight hashes, maximum latency, computational load, confidentiality flags, and fees. Miners complete the inference and return proofs, which validators incorporate into blocks to complete settlements.The initial supply of FLOP is approximately 2.48346 billion tokens, all allocated for airdrops, with no VC pre-mining or auctions. The first phase of reward distribution allocates 75% to miners, 10% to validators, 10% to agents, and 5% to regular stakers. The average block time for the network is 1 second, with a roadmap goal of sub-second block times. The initial block reward is 96 FLOP, halving every 730 days, for a total of five halvings, after which it will permanently remain at 3 FLOP.The maximum number of validators is capped at 1,000, with approximately 50 rotating monthly based on verified workload and online rates. Miners and validators must stake FLOP, and malicious behavior may face penalties of up to full forfeiture and bans. Governance is conducted through FLOP improvement proposals, requiring a two-thirds approval from active validators in most cases.
