From Robinhood to Arc, Uniswap Captures Massive Traffic as v4 Accelerates Liquidity Grab

Author: Nancy, PANews

Arc's mainnet debut got off to a hot start, briefly capturing the market's attention, but it couldn't escape a "one-day wonder" performance. In this short-lived on-chain frenzy, Uniswap captured the traffic and emerged as the winner.

From Robinhood Chain to Arc, the growth dividends brought by new chain traffic are becoming a key driver of Uniswap's recent growth. At the same time, v4 is rapidly catching up to v3, gradually becoming an important force in Uniswap's expansion of its liquidity landscape.

Riding the Robinhood Chain Dividend, Uniswap Captures Arc Traffic

Over the past month, UNI has staged a strong rally, with a cumulative gain of 108.9%, rising from $3.2 to $6.9. Even as the broader crypto market has recently pulled back, UNI has continued to climb against the trend. Behind the sustained rise in token price, in addition to improving market sentiment, Uniswap's growing trading volume and protocol revenue have become important fundamental support.

DeFiLlama data shows that over the past month, Uniswap has processed cumulative trading volume exceeding $79.5 billion, surpassing the combined trading volume of PancakeSwap, PumpSwap, and Aerodrome over the same period. In the past 24 hours alone, Uniswap's trading volume approached $3.86 billion, several times that of second-place PancakeSwap.

The sustained growth in trading volume has also directly driven up Uniswap's protocol revenue. DeFiLlama data shows that over the past quarter, Uniswap's protocol revenue reached $23.15 million, and over the past 30 days it reached $5.26 million, ranking first among DEX revenues.

Currently, Robinhood Chain has become the main driver of Uniswap's recent revenue growth. Taking September data as an example, this month Robinhood Chain contributed approximately $6.48 million in protocol revenue to Uniswap, accounting for 65.5% of total revenue over the same period. Although revenue from Robinhood Chain has declined from its earlier peak as the meme trading frenzy cooled and some high-fee pools were withdrawn, Uniswap's overall protocol revenue has not seen a significant decline.

After the fee switch on Robinhood Chain was activated at the end of July, the pace of UNI burns accelerated significantly. Dune data shows that in less than two months, UNI burns contributed by Robinhood Chain have accounted for 19.3% of total burns. Looking at daily data, this share is even higher: on September 17, UNI burns from Robinhood Chain accounted for half of the day's total burns, significantly higher than other networks such as Ethereum and Base.

Leveraging its liquidity and user base as a leading DEX, Uniswap has also become a priority partner for new chains competing for traffic. On the first day of Arc's mainnet launch, Uniswap announced full integration with Arc and became its preferred DEX. As trading activity on Arc heated up rapidly after launch, Uniswap gained a new trading traffic entry point.

Dune data shows that on September 16, Uniswap's trading volume on Arc exceeded $410 million. By comparison, Uniswap's trading volume on the first day of Robinhood Chain's mainnet launch was approximately $70.5 million. Looking solely at first-day mainnet trading volume, Arc brought significantly more traffic to Uniswap than Robinhood Chain. However, this round of Arc trading frenzy brought Uniswap mostly incremental traffic, and since Uniswap has not yet activated the fee switch on Arc, this portion of trading volume cannot yet be converted into UNI burns.

At the same time, as Arc ecosystem tokens have generally seen significant pullbacks, on-chain liquidity has also declined, and whether the short-term trading frenzy can continue remains uncertain. For Uniswap, whether Arc can, like Robinhood Chain, transform from a short-term traffic entry point into stable trading volume and sustained revenue remains to be validated by subsequent market performance.

New Chain Traffic Boosts V4 Growth, Hook Mechanism Exposed to Malicious Risks

Uniswap is returning to the center of on-chain liquidity competition, and the rise of V4 is becoming an undeniable driving force. Among its features, Hook, as one of V4's core innovations, is gradually becoming an important growth point for Uniswap.

Blockworks data shows that Uniswap v4 is steadily narrowing the trading volume gap with v3, with its latest weekly trading volume share rising to 48%, approaching v3's 52%. In terms of fee revenue, v4's weekly fee revenue share has also risen from 8% at the end of July to 25%, while v3's share fell from 87% to 67% over the same period.

The penetration speed of V4 on new chains is noteworthy. On Robinhood Chain, v4's weekly trading volume share has reached 42%; on Base, this figure is 11%, and on Arbitrum and Optimism it is 18% each. Even on the just-launched Arc, v4's single-day trading volume contribution share has reached 29.7%.

In addition to steadily increasing market share, the asset structure of v4 trading is also changing. In July, v4 trading was mainly concentrated in meme coins, stablecoins, and L1 and L2 tokens; by August, stablecoins, tokenized assets, and meme coins became the main trading types, with meme coins' trading share declining from the previous month. Stablecoins have been able to maintain an important position in v4 trading because the version's underlying execution efficiency and fee design are more suited to stablecoin trading needs.

As the v4 version expands rapidly, Hook trading is also accelerating. Blockworks data shows that most of v4's trading activity still comes from regular pools, but Hook-related trading has been climbing since August, currently accounting for 44%, up from single-digit levels previously.

Hooks allow developers to customize dynamic fees, token issuance mechanisms, RWA and permissioned pools for liquidity pools based on different assets and trading scenarios. Compared to v3's relatively fixed fee configurations, v4 offers a more flexible trading mechanism, enabling liquidity pools to be customized for specific scenarios.

Robinhood Chain is one example. As an L2 focused on tokenized stocks and other assets, its cumulative trading volumes on Uniswap v3 and v4 have reached $24.3 billion and $23.35 billion respectively, already quite close in scale. In the latest weekly trading volume, v3 accounts for 58% and v4 for 42%, and the gap between the two has been narrowing since the initial launch. This also indicates that v4's growth is not merely trading migration driven by version iteration, but is also related to the emergence of new chains, new assets, and customized trading needs. As more assets and trading scenarios come on-chain, the Hook mechanism will also expand more liquidity scenarios for Uniswap.

However, as the application scale of v4 and Hooks expands, related security risks are also beginning to attract attention. The 0x protocol recently posted that it has observed a significant increase in the number of malicious Uniswap v4 Hooks. Such Hooks may display favorable prices during the quote request phase but change the actual execution price at trade settlement, misleading aggregators, wallets, and trading applications, ultimately harming user interests.

0x stated that it has routed 81.92 million transactions this year, with total trading volume reaching $42.67 billion, of which approximately 70% of transactions involve Uniswap liquidity. The protocol conducted static analysis, dynamic analysis, and trade data observation on 84,163 Hooks across 6 chains, and based on this determined that only 19.4% are safe Hooks, 54.2% are classified as malicious, and another 26.4% may have malicious behavior.

The protocol also pointed out that some malicious Hooks distinguish between quote requests and real trading scenarios by detecting the Ethereum Virtual Machine (EVM) environment or using random fees. This means that the price users see during the quote phase may not be realized at settlement, and the actual value of assets received may be up to 50% lower than the quoted price. In response to this issue, 0x stated that it has adopted measures such as advanced detection and liquidity pool review to prevent related pools from entering its routing system, and reminded routers, applications, and users to pay attention to whether quotes match actual execution results.

In response, Uniswap founder Hayden Adams said that the so-called "routing to bad Hooks" issue is a technical mishandling, and the team can seek assistance to resolve it. He also emphasized that Uniswap v4 Hooks have already unleashed significant innovation potential, and recommended that developers use the Uniswap API. He explained that the Uniswap API supports obtaining the best market prices, avoiding malicious Hooks, and accessing all Uniswap liquidity without additional routing fees. In addition, the API supports cross-chain swaps and integrates external liquidity through aggregator Hooks, further expanding into a complete aggregator.

From the increase in v4 trading share to the continued growth in Hook trading share, Uniswap is expanding into new chain and new asset markets through more flexible liquidity mechanisms. But as customization features become increasingly rich and asset boundaries continue to expand, balancing innovation and security will also become a challenge Uniswap needs to face.
