The on-chain spot exchange Rialto has launched the Robinhood Chain token issuance platform Varo. Varo adopts a contract architecture based on Uniswap V3, with no binding curve or graduation fees. Tokens can be traded instantly through the Uniswap liquidity pool at the time of issuance and can be integrated with platforms such as Uniswap, GMGN, LI.FI, BasedBot, and Definitive.Each token issued on Varo has a fixed supply of 100 million tokens, and the initial market value is set by Varo (for example, 60,000 USDG or 30 WETH). There are no reserved shares for teams or developers, and liquidity positions are permanently locked in the contract. The trading fee is 1%, of which 30% belongs to Rialto.The project team also stated that a "one code corresponds to one token" mechanism is used to prevent confusion with tokens of the same name and that the higher initial market value setting aims to reduce the economic incentive for sniper bots to accumulate tokens at low cost.

According to DefiLlama data, the Ethereum chain random NFT acquisition protocol Fake World Assets, developed by the two-person team Token Works, surpassed the daily revenue of Collector Crypt on Solana within four days of its relaunch on July 20.On July 25, the peak daily revenue reached $447,604, with total fees of $1.6 million, and approximately 90,000 transactions including about 35,000 draws, with a trading volume of around 2,000 ETH. After that, activity declined, with revenue in the past 24 hours dropping to $167,869, ranking second in daily revenue among Ethereum protocols, only behind Sky ($464,303), and ahead of Aave ($105,282) and Uniswap ($76,028).In this protocol, depositors list NFTs along with their pledged ETH collateral (similar to Uniswap V2 trading pairs), where the collateral determines the weight of each NFT and provides depositors with irrevocable continuous bids to reacquire the NFT. Anyone can pay the acquisition price generated by the liquidity pool to obtain a randomly selected NFT.The pool has accumulated over 1,500 NFTs including CryptoPunks, with randomness provided by Chainlink VRF. The token emission incentives expire 15 days after launch, and daily fees have decreased by about half from their peak. Collector Crypt on Solana remains the leader in this sector, with users spending over $209 million on its card packs in June alone.

Uniswap founder Hayden Adams posted on the X platform in response to the controversy over the v4 fee switch, clarifying that "the reduction of LP fees" is a misunderstanding; the protocol fees are additive rather than deductive, and LPs still earn 30 basis points per transaction.Regarding the claim that "the protocol takes 25% of LP profits," he stated that on a 30 basis point pool, the protocol fee is 5 basis points, accounting for about 14% of the total transaction fees, and LPs have not lost any of their earnings. Hayden Adams also pointed out that centralized exchanges charge 100 to 200 basis points per transaction, making Uniswap's 5 basis point fee at the 30 basis point level 20 to 40 times cheaper. He also criticized some forked projects that charge 100% transaction fees but use uneven inflation set by token voting to "compensate" LPs.

Uniswap stated that the cumulative trading volume of Robinhood Chain on Uniswap has exceeded 10 billion dollars, achieving this scale in less than a month.

According to official news, Uniswap has launched Permissioned Pools, a new hook standard in Uniswap v4 that supports permissioned asset trading through automated market makers (AMM), with compliance enforced directly on-chain. Permissioned asset pools are collaboratively built by on-chain asset management teams. The first batch of partners includes Superstate, Securitize, and Dowgo.

The Robinhood Chain token launch platform Pons will release version 2, planning to introduce multiple feature updates. It is reported that Pons v2 will introduce a Bonding Curve mechanism priced in ETH, remove trading restrictions for non-developer wallets, and support custom trading pairs, including RWA assets such as USDG, NVDA, AAPL, and HOOD.In addition, Pons will adopt a redesigned fee structure using Uniswap V4 pools and Hook, with creators defaulting to receive fees in ETH; when the token value reaches 4.2 ETH, it will automatically graduate to a permanently locked full-range position on Uniswap V4. Other updates include the addition of a CTO feature with a 3-day time lock, support for collecting fees in stablecoins or other tokens, and the introduction of an optional tax mechanism for each buy and sell transaction.

Uniswap announces the official launch of DualPool Hook. DualPool is an open-source Uniswap v4 Hook, jointly designed and developed by Spark and Uniswap Labs, allowing market makers to earn yields by depositing idle assets into lending protocols during the waiting period for liquidity funds to be executed, and to withdraw funds back to the liquidity pool when a transaction occurs.From an external perspective, DualPool is indistinguishable from a regular Uniswap v4 liquidity pool, and traders, aggregators, and solvers still complete transactions through the Pool Manager. Its internal mechanism is that liquidity funds are stored in an ERC-4626 yield vault and are automatically withdrawn when a transaction needs to be executed, deployed to concentrated liquidity positions, thereby ensuring transaction execution while allowing idle funds to continuously generate lending yields.

According to The Block, Uniswap governance will conduct two key on-chain votes from July 19 to 26. The first proposal aims to enable protocol fees for the v4 version liquidity pools for the first time, covering seven chains: Ethereum, Arbitrum, Base, BNB Chain, Polygon, Optimism, and Robinhood Chain, targeting three types of pools: static fee pools, pools initiated through continuous liquidation auctions, and aggregator hooks pools; proposals for the remaining five chains will be submitted later.The second proposal, submitted by Uniswap founder Hayden Adams, aims to extend the fee mechanism of v2 and v3 to Robinhood Chain. The fees generated from both proposals will enter the UNIfication burn mechanism. Last month, the Uniswap protocol set a record by burning 186,000 UNI in a single day.

Uniswap founder Hayden posted on the X platform that Uniswap has just submitted two governance proposals for final on-chain voting, including enabling v2 and v3 protocol fees on the Robinhood Chain, as well as enabling v4 protocol fees on Ethereum, Base, Arbitrum, Robinhood, BNB, Polygon, and Optimism. The remaining third proposal related to v4 chain is about to be submitted.Both proposals will direct all new protocol fees into the existing UNI burn mechanism. Based on the current trading volume, especially the trading volume related to Robinhood, the impact on UNI burn is expected to be significant.

DeFi infrastructure company Enso disclosed in a report a type of malicious liquidity pool called "toxic pools," which manipulates trading simulations to return false optimal quotes to wallets and DEX aggregators, and alters logic during actual on-chain execution. Enso stated that the relevant malicious contracts can identify read-only simulation environments and return optimized prices, but once the trades are broadcasted on-chain, they execute at worse prices or result in transaction failures.A manipulated Curve pool processed over 129,000 exchanges, resulting in approximately $225,000 in inflated quotes, with over 37,000 transactions rolling back and consuming nearly $30,000 in gas fees. On Polygon, a malicious Uniswap v4 hook attracted routing systems with false exchange rates, subsequently triggering a 99.1% transaction failure rate. Enso stated that it has updated its execution protection product Enso Shield to detect false quotes in Ethereum and Polygon environments.

According to a report by The Block, a study commissioned by 1inch and conducted by Dune found that approximately 85% of concentrated liquidity in decentralized exchanges such as Uniswap v3, Uniswap v4, PancakeSwap v3, and Aerodrome Slipstream is not effectively utilized. The research analyzed the performance of nearly 200 active liquidity pools across 7 chains in 26 weekly snapshots, tracking an average liquidity of about $1.84 billion per week, of which approximately $1.6 billion is in an inefficient state.Specifically, on the Uniswap v3 platform, among the liquidity that has deviated from the market-making price range, 44.5% has not been adjusted for more than 90 days, making it the platform with the highest proportion in this study; in contrast, Aerodrome has a ratio of about 20%, with 58% of idle funds having been adjusted within the last 30 days.Additionally, only about 35% of idle funds are located within 5% of the market price, approximately 43% deviate from the market price by more than 25%, and another 17% deviate by more than 100%. In terms of fund size, positions exceeding $1 million hold about 47% of idle funds, amounting to approximately $260 million.

Uniswap initiated a governance proposal to extend the protocol fee collection and UNI burning mechanism to the Robinhood Chain, covering versions v2, v3, and v4.According to the proposal, the protocol fees generated on the Robinhood Chain will be sent to the TokenJar contract on that chain, and Searchers can redeem the fees by bridging UNI back to the Ethereum mainnet and sending it to the burn address.

Interactive Brokers announced on Tuesday the expansion of its digital asset business, adding trading tokens such as Aave, Aptos, Canton, Lido DAO, Monad, NEAR Protocol, Plasma, Pax Gold, and Uniswap, and supporting 24/7 stablecoin wallet transfers via USDC, PYUSD, and RLUSD.As of mid-2026, Interactive Brokers manages approximately $930.3 billion in client assets, with cryptocurrency trading commissions starting at 0.12% to 0.18% of the total transaction amount, with a minimum order fee of $1.75, and no additional spreads, markups, or custody fees. The company stated that accounts in the UK and Ireland cannot use stablecoin two-way deposits, and clients of the Irish affiliate cannot access the newly launched crypto assets.

Uniswap announced that teams can now directly configure and initiate Uniswap Auctions in the Uniswap Web App. This feature is supported by Continuous Clearing Auctions (CCA), which are used for on-chain token distribution, price discovery, and liquidity guidance.According to reports, CCA is now live on the Robinhood Chain, allowing teams to run token auctions on-chain, discover more market-oriented issuance prices, and launch liquidity on Uniswap v4 after the auction ends. Previously, projects like Aztec and Cap have used Uniswap Auctions for permissionless and transparent on-chain token distribution.Uniswap stated that the new launch process supports importing existing tokens or creating new tokens, and allows for configuring auction parameters and liquidity pool settings after the auction. The current interface supports Ethereum, Base, Arbitrum, and Unichain, with plans to expand to more chains in the future.

DeFiLlama data shows that Uniswap's trading fees in the past 24 hours were approximately $5.027 million.Uniswap founder Hayden Adams stated that Uniswap's daily trading fees are second only to Tether and Circle, and significantly higher than projects like Hyperliquid and Pump.

Uniswap founder Hayden posted on the X platform, stating that many people have not noticed that the Uniswap protocol fees have been activated and UNI has been burned. He continues to receive replies believing that the protocol fees have not been activated.Currently, there are 3 governance proposals being voted on: 1) Robinhood Chain fees (v2/v3); 2) v4 fees; 3) fee bridge cleanup on xlayer, ava, megaeth, sonium.

Uniswap founder Hayden posted on the X platform that 99.5% of the DEX trading volume related to Robinhood Chain comes from Uniswap.

According to Onchain Lens monitoring, the Summer.fi attacker wallet (0x7BF...b3bdca) received 6.017 million DAI from the attack event; since then, 1.35 million DAI has been transferred, exchanged for ETH via Uniswap, and transferred to Tornado Cash through a second wallet (0x46e...eba7).Currently, the original wallet still holds approximately 4.67 million DAI, and the second wallet still holds 50 ETH.

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.

The security analysis platform GoPlus tweeted regarding the incident where "a user exchanged approximately 1126 ETH (about 2.01 million USD) for 5776 LIT (about 14,000 USD) on Uniswap, resulting in a loss of nearly 2 million USD." The core reason for this incident was not a sandwich attack, but rather backrunner arbitrage within the same block. The routing contract injected a large amount of WETH into a liquidity-poor AVAIL/WETH trading pool, causing the user to buy AVAIL at a severely deviated market price (about 120 times the reasonable price). Subsequently, within the same block, the backrunner executed a reverse trade on the pool with a minimal amount of AVAIL at the real price, withdrawing approximately 1072 WETH, and paid most of it (about 1018 ETH) as builder payment to Titan Builder.
