Ethereum News: Silicon L2 Shutdown, BlackRock ETH Buys and Machi Loss

Ethereum News Today: ARK, BlackRock and Silicon L2 Shutdown Updates

Ethereum news today spans four corners of the ecosystem: a smaller L2 network winding down, a debate over value capture, a trader's rough week, and a pause in institutional buying. Together, the stories from September 3, 2026 show a network maturing in some areas while consolidating in others, even as demand for ETH stays healthy.

At a Glance

• Layer 2 network Silicon has stopped new deposits and begun shutting down, with about $9.75 million in assets still on chain and a December 31 withdrawal deadline.

• ARK Invest researcher Lorenzo Valente argues Ethereum updates built the most successful L2 franchise model in crypto but charges too little for settlement, unlike Solana and Hyperliquid.

• Trader Machi made roughly $11 million in a week, then gave back about $7 million trading ETH and BTC.

• BlackRock 15-day, $1.16 billion ETH buying streak has ended, though its crypto ETF clients have not net-sold since mid-August.

Silicon Network Begins Shutdown With $9.75M Still on Chain

The Ethereum L2 network Silicon stopped accepting new cross-chain deposits on September 2 and entered its shutdown process. Users now have until December 31 to withdraw assets before the network and its block explorer cease operations. 

As a non-custodial service, funds left unclaimed after the deadline may become unrecoverable. Silicon runs on Polygon CDK and was tied closely to Korbit, a major South Korean exchange whose Web3 Wallet is also being discontinued.

Which Assets Are Still Locked on Silicon?

Data from L2BEAT shows roughly $9.75 million remains on the chain:

Assets originally bridged in can return to the mainnet during the withdrawal window, provided users keep enough ETH for gas. Tokens issued natively on Silicon face a harder path, since they can't bridge back directly and depend instead on whatever liquidity remains inside the shrinking network.

Shutdown Timeline

• September 2, 2026: New deposits stop; shutdown begins.

• September to December 2026: Window to withdraw or transfer eligible assets.

• Before December 31: Final deadline to exit funds.

• After December 31: Network and explorer shut down permanently; unrecovered assets may be lost.

ARK Says Ethereum Built a Successful L2 Model but Captures Too Little Value

ARK Invest researcher Lorenzo Valente compared Ethereum, Solana, and Hyperliquid to McDonald's, Chipotle, and In-N-Out, arguing each represents a distinct value-capture structure rather than variations on one theme. 

In his view, Ethereum resembles a franchise system that expanded successfully through L2s but undercharges for settlement, building the biggest franchise network in crypto without collecting enough rent. 

Solana behaves more like a company-owned model that keeps fees and MEV internal. Hyperliquid (HYPE) takes vertical integration furthest, with no VC backing and token buybacks creating the shortest value-capture chain, though that concentration carries its own risk.

Machi Loses $7M Trading ETH and BTC in One Week

Analytics platform Arkham reported that trader Machi earned about $11 million in a single week, then lost roughly $7 million the following week trading ETH and BTC. The swing is a reminder of how volatile outcomes can be even for experienced traders, and whether Machi recovers the loss remains an open question.

BlackRock's $1.16B Buying Streak Comes to an End

BlackRock's ETH accumulation streak has concluded after the firm bought approximately $1.16 billion worth over 15 consecutive days, with its most recent ETF print showing zero net flows. Notably, its clients have not net-sold since mid-August, suggesting the pause reflects a natural lull rather than a shift in institutional sentiment.

What These Developments Mean for Investors

Silicon's closure shows the pressure smaller L2s face as liquidity consolidates around larger Ethereum networks like Base and Arbitrum. ARK's critique raises fair questions about whether Ethereum's settlement layer is priced correctly as L2 activity grows. Machi's losses are a reminder of short-term trading risk, while BlackRock activity sustained, if paused, buying signals demand hasn't disappeared.

What to Watch Next

Track the Silicon withdrawal deadline, whether more small L2s face similar consolidation, whether the value-capture debate prompts any protocol changes, and whether BlackRock resumes purchases in the coming weeks.

Ethereum news today reflects a mixed but active landscape: L2 consolidation continues, analysts are scrutinizing the network's value-capture model, large traders remain exposed to sharp swings, and institutional demand has stayed strong even as BlackRock's streak takes a pause.
