Uniswap Labs Officially Launches Layer-2 ‘Unichain’

Uniswap Labs, the primary developer behind one of the largest decentralized exchanges (DEX), Uniswap, shared Tuesday that its long-awaited layer-2 network, Unichain, is now live.
Powered by Optimism’s OP stack, Unichain—like other layer-2s on Ethereum—offers faster and cheaper transactions compared to Ethereum’s mainnet. Developers can deploy apps onto the network, which has been optimized specifically for decentralized finance (DeFi) and aims to serve as «the home for liquidity across chains,» according to Uniswap Labs.
For Uniswap Labs, the benefit of launching a layer-2 is twofold: it will provide a better experience for users of Uniswap and similar platforms, and it will create a new revenue opportunity in the form of network fees. A representative for Uniswap Labs told CoinDesk that «around 20%» of the chain’s revenue will go directly to the company.
Unichain has been in testing since October 2024 and is classified by Uniswap Labs as a «stage-1» rollup, meaning it has elements of decentralization but retains some centrally-controlled safeguards at this early phase.
The network is built on the OP Stack, a modular framework that lets developers build interoperable layer-2 chains based on Optimism’s optimistic rollup technology. Several well-known teams have come out with their own OP Stack-based layer-2’s, including Coinbase’s ‘Base’, Kraken’s ‘Ink,’ World’s ‘World chain,’ and Sony’s ‘Soneium.’
What makes Unichain different?
Dozens of layer-2 chains have popped up over the last few years, and Uniswap co-founder Hayden Adams believes that most of them will ultimately be used for specific use cases rather than serve as general-purpose blockchains. “We are anticipating a world of many, many different use cases, of which trading is a small subset,” Adams told CoinDesk in an interview.
In collaboration with Ethereum research and development firm Flashbots, the Uniswap team said it has created a Trusted Execution Environment (TEE) on Unichain. The TEE is a secure area for more sensitive transactions and is meant to optimize the chain for DeFi by allowing for more advanced trades and faster transaction finality.
“Essentially, we want Unichain to be a chain that is good for liquidity creation, good for trading, good for applications that need to be co-located with them, and then good for applications that essentially want access to liquidity but should not be co-located,” Adams said.
Building on Optimism
As part of its integration with Optimism’s «Superchain» ecosystem, Uniswap Labs has agreed to give 2.5% of Unichain’s gross revenue—or 15% of Unichain’s net revenue, whichever is greater—to the Optimism Collective, a consortium of people and companies that steward Optimism’s rollup tech. Many of the chains in the Optimism Superchain ecosystem have agreed to similar setups, including Coinbase and Kraken.
In exchange for building on Optimism, both Coinbase and Kraken received grants of Optimism’s OP governance tokens from the Optimism Foundation, which controls a treasury of tokens earmarked to help grow the ecosystem. Coinbase agreed to receive up to 118 million OP tokens, while Kraken agreed to 25 million. Uniswap Labs declined to comment on whether it had its own deal with the Optimism Foundation.
Ahead of Unichain’s mainnet launch, Uniswap Labs announced that 65% of the chain’s net revenue will go to the Unichain Validation Network—a group of validators and stakers securing the blockchain.
UVN will act as “another layer of transparency and validation of the network,” Adams said.
“Part of the uniqueness about us as a project that has always been decentralized first, is that we are actually reducing the role and the power of sequencer relative to other things that are running more centralized sequencers,” Adams added.

London Stock Exchange Unveils Blockchain-Based Platform for Private Funds

The London Stock Exchange Group (LSEG) said it facilitated the first transaction on a new blockchain-based platform for private funds.
LSEG’s Digital Markets Infrastructure (DMI), built using Microsoft Azure, is designed to use blockchain technology across the full lifecycle of an asset, from issuance to settlement, with greater scale and efficiencies than existing systems, according to a Monday announcement.
Investment manager MembersCap and digital asset exchange Archax were onboarded as DMI’s first clients and conducted the first transaction, which raised money for MembersCap’s MCM Fund 1.
LSEG said it will ensure DMI works with current market services in blockchain technology as well as traditional finance (TradFi).
DMI and its first transaction are «significant milestones demonstrating the appetite for end-to-end, interoperable, regulated financial markets» blockchain technology, Dark Hajdukovic, LSEG’s head of digital markets infrastructure, said in the statement.
TradFi exchanges in numerous markets have been embedding blockchain technology into their platforms as a means of increasing efficiency and reducing costs. Last week, the Nasdaq filed a proposal with the U.S. Securities and Exchange Commission (SEC) to tokenize stocks on its exchange for trading on the blockchain with trades assigned the same priority as the legacy method.

Bitcoin Cohorts Return to Net Selling as Market Continues to Consolidate

Glassnode data shows that all wallet cohorts have returned to distribution mode, with a net selling of bitcoin, according to the Accumulation Trend Score breakdown by wallet cohort.
This metric disaggregates the Accumulation Trend Score to show the relative behavior of different groups of wallet. It measures the strength of accumulation for each balance size based on both the entities’ size and the volume of coins acquired over the past 15 days. (For more details on the methodology, see this Academy entry.)
- A value closer to 1 signals accumulation by that cohort.
- A value closer to 0 signals distribution.
Exchanges, miners and other similar entities are excluded from the calculation.
Currently, all cohorts, from wallets holding less than one bitcoin to those holding more than 10,000, are net sellers. This follows last week’s rally, when some whales — most notably the 10-100 BTC and 1,000-10,000 BTC cohorts were buying. They have since flipped back to selling.
Bitcoin was recently hovering near $117,000 after Asia’s trading session pushed it up from $115,000 dollars over the weekend. Over the past three months, Asia has consistently driven bitcoin roughly 10 percent higher, according to Velo data. In contrast, the European trading session has been marked by pullbacks, which has been seen on Monday so far. In addition, bitcoin is down more than 10% in the EU market over the past three months.
Overall, the market remains in consolidation, a trend likely to persist through September. On current data, the $107,000 marked at the start of September still appears to be the most probable bottom.

Memecoins Under Pressure as SHIB, Dogecoin Slide After Shibarium Loses $2.4M in Hack

Top meme tokens traded under pressure as a multimillion dollar hack of Shiba Inu’s layer-2 network, Shibarium, dented investor confidence in joke cryptocurrencies.
On Sunday, Shibarium fell victim to a flash loan attack on its validator system, which drained about $2.4 million in ether (ETH) and SHIB. The CoinDesk Memecoin Index has dropped 6.6% in the past 24 hours. The broader market CoinDesk 20 Index (CD20) is down just 2.3%.
The attacker borrowed 4.6 million BONE, the governance token for the Shiba Inu ecosystem, often linked to the decentralized exchange (DEX) ShibaSwap, through a flash loan to gain control of the majority of validator keys. The keys act as gatekeepers of the network, confirming transactions and ensuring security.
With that control, the attacker was able to game the system into approving unauthorized transactions and walk away with a large amount of crypto assets from the bridge that connects Shibarium with the Ethereum blockchain. The process is akin to someone temporarily taking over a bank’s security system to approve unauthorized withdrawals. A flash loan is a loan raised with no upfront collateral and returns the borrowed assets within the same blockchain transaction.
The Shiba inu team was able to prevent a bigger, more serious breach because the BONE tokens used to gain control were reportedly tied to validator 1 and remained locked by the staking rules.
Nevertheless, markets reacted negatively breach, which again underscores the perennial security issues with blockchain technology.
Memecoins drop, broader market bid
SHIB fell by the most in three weeks on Sunday (UTC), losing 4% $0.00001369, and has continued to weaken to trade recently at $0.00001359. The cryptocurrency experienced considerable volatility throughout the 23-hour trading window ended Sept. 15 at 02:00 UTC, with the aggregate range encompassing $0.000006191, a 4% oscillation from peak to trough.
The session commenced with pre-dawn fragility as SHIB retreated from $0.000014156 to establish a pivotal trough of $0.000013547 at 14:00 UTC. Volume of 1.064 trillion tokens surpassed the 24-hour mean, signaling robust distribution pressure and prospective capitulation, according to CoinDesk Research’s technical analysis model.
The BONE token, which initially doubled to over 36 cents, is now down over 2% on a 24-hour basis, trading at around 20 cents.
According to the technical analysis model:
- SHIB established a critical underpinning at $0.000013547 during elevated volume selling pressure exceeding 1.064 trillion tokens.
- The token constructed successive higher lows and consolidation parameters between $0.000013600-$0.000013780.
- Recovery momentum is demonstrated by ascending channel formations with sustained higher lows, indicating potential continuation towards the $0.000014000 resistance.
- Volume patterns exceeded 24-hour averages during the decline phase, confirming potential capitulation levels.
- Terminal hour trading exhibited decisive upward momentum with 1% appreciation, confirming a breach above the resistance threshold.
Large DOGE transfers add to bearish sentiment
Meanwhile, SHIB’s peer dogecoin (DOGE) fell 4% to 27.80 cents on Sunday and has since lost further 5% to 27.36 cents, according CoinDesk data.
A massive transfer of DOGE to a centralized exchange likely added to the bearish mood in the market. According to Whale Alert, crypto exchange OKX received 119,306,143 DOGE, worth over $34 million, from an unknown wallet. Such large transfers are typically associated with an intention to liquidate holdings.
