Why devs say Uniswap’s v4 launch will kick start Ethereum’s ‘DeFi renaissance’ – DL News
- Ethereum DeFi developers are optimistic about Uniswap V4’s potential.
- The blockchain network has been pilloried in recent years by agile competitors and infighting.
Despite hosting a $75 billion ecosystem, Ethereum is clunky, riddled with hidden perils, and missing much of the functionality traders expect of centralised trading venues like Coinbase.
On Friday, Uniswap, Ethereum’s biggest decentralised exchange, launched its fourth version — V4 — introducing new features with the potential to vastly improve the DeFi experience for users.
“The DeFi renaissance is coming, and Uni V4 is going to be at the heart of it,” Ari Rodriguez, chief technology officer at DeFi protocol Arrakis, which builds on top of Uniswap V4 told DL News, echoing the sentiment among other developers.
“Uni V4 can be thought of as a foundational layer and projects will build all kinds of new protocols on top of this,” Rodriguez said. “We’ve barely scratched the surface of what’s possible.”
But nothing is guaranteed, and adopting the new features made possible by V4 takes time.
Rival blockchain Solana is biting at Ethereum’s heels. At the same time, the Ethereum community is embroiled in infighting over a perceived lack of leadership at the blockchain’s nonprofit foundation.
A DeFi renaissance
In 2020, activity on Ethereum exploded as developers began to fully explore the possibilities of the blockchain.
During this period, known as “DeFi summer,” dozens of new, innovative protocols hit unprecedented valuations, enriching those who had noticed the trend early.

Many of Ethereum’s faithful, nostalgic for this heady time, are hoping that new products like Uniswap V4 can kick start another wave of innovation.
Uniswap V4′s most-anticipated feature is Hooks — extra snippets of code that let developers build features such as limit orders, time-weighted token purchases, and dynamic fee systems that react to market volatility, directly on the Uniswap protocol.
Hooks open up more yield strategies and new user experience features, such as automatic limit orders and interactions with lending markets, BP, the pseudonymous founder of liquidity management protocol Gamma, told DL News.
Rodriguez said Arrakis will use Hooks to help token issuers manage their Protocol Owned Liquidity.
Protocol Owned Liquidity is where a project uses its treasury or reserves to provide liquidity on decentralized exchanges like Uniswap.
But there are trade-offs. Hooks make providing liquidity on Uniswap V4 “an order of magnitude” more complex than on its predecessor, Uniswap V3, Rodriguez said.
“DeFi is getting more sophisticated,” BP said. “It will bring in a lot more creativity and differentiation to the ecosystem.”
Other new Uniswap V4 features include combining all the code that manages liquidity into a single smart contract. This so-called singleton design reduces the computations needed when users swap tokens on Uniswap, reducing the fees they need to pay.
BP said the singleton contract means Gamma can deploy new yield and liquidity strategies that had previously been too costly for users.
If these innovations capture the market’s attention, the potential growth could be huge. At the start of the 2020 DeFi summer, Ethereum DeFi protocols held around $600 million. By the end of the year, that number had swelled to $17 billion.
Solving problems
Aside from improving existing apps, Uniswap V4 also makes new protocols possible.
One of Uniswap’s most persistent problems is that trading bots syphon money from liquidity providers via something called LVR — or loss-versus-rebalancing.
LVR refers to the losses LPs incur due to arbitrage bots taking advantage of stale prices in liquidity pools. By rebalancing pools, bots earn a small profit and make prices more competitive for traders — but at the expense of liquidity providers.
Angstrom, a project building on top of Uniswap V4, says it can stop bots from impacting LPs using Hooks.
Angstrom isn’t the only project working on eliminating LVR. Rival exchange CoW Swap is also tackling the problem through its automated market maker.
Another project called LIKWID is using Uniswap V4 to create a margin trading protocol that doesn’t rely on price oracles — services that provide offchain price information to onchain smart contracts.
Some of DeFi’s biggest exploits in recent years have been caused by hackers finding ways to manipulate price oracles, letting them steal millions of dollars from DeFi protocols.
Whether these improvements will be enough to change Ethereum’s fortunes isn’t clear.
The high-profile crypto collapses of 2022 plunged Ethereum DeFi into a years-long ice age. Although Bitcoin and other crypto assets roared to all-time highs over the past year, Ethereum and its DeFi ecosystem have fallen short.
Ether’s price continues to lose ground against rivals like Solana and XRP.
The launch of Uniswap V4 barely moved the price of the protocol’s own UNI governance token.
