Developments from the past week followed a familiar pattern: the loudest headline was a founder selling tokens, while the more consequential news sat one layer below. Governance decisions are reshaping protocol economics. Institutional capital is quietly accumulating. Miners are repositioning as compute infrastructure companies. The eight developments below span protocol design, stablecoin expansion, capital markets, and one lawsuit that reopens the worst chapter in recent crypto history.

Vitalik Is Selling, But the Reason Matters

Vitalik Buterin's tracked wallets fell from roughly 241,000 ETH to 224,000 ETH over the course of February. The 17,000 ETH sold corresponds directly to an allocation he declared in January: funds earmarked for privacy research, open hardware, and software security projects. Execution ran in small batches via CoW Protocol, the standard approach for large holders avoiding slippage. The Ethereum Foundation announced a parallel cost-cutting period, trimming non-essential spending while maintaining its technical roadmap.
‍

The optics are uncomfortable regardless of the stated purpose. Ethereum is down substantially from its October high, staking yields have compressed to around 2.8%, and corporate holders are sitting on large unrealised losses. A steady outflow from the founder's wallet into that environment reinforces questions the ecosystem has struggled to answer: what is ether's investment case in 2026, when it is underperforming gold, underperforming Bitcoin, and generating less fee revenue than at its peak? The sales are not the cause of Ethereum's problems. They are a visible symptom of a protocol still searching for a clear value proposition at current prices.

Uniswap Votes Itself Into Profitability

For most of its existence, Uniswap processed trillions of dollars in trading volume and passed all fees to liquidity providers. The protocol generated activity but no income of its own. That changed late last year when governance activated a fee switch redirecting a share of trading fees toward UNI burns, and this week a follow-on vote extended the model to eight additional Layer 2 chains.
‍

The new v3OpenFeeAdapter removes the need to activate fees pool by pool, applying protocol charges automatically across all v3 liquidity pools based on their fee tier. Since late 2025, existing fee activation has burned over $5.5 million in UNI. The expansion adds an estimated $27 million in annual revenue on top of that.
‍

For Q1 2026, DeFi Llama recorded Uniswap's first measurable gross profit at roughly $3.12 million, compared to effectively zero across all prior periods. Whether the higher protocol cut migrates some fee-sensitive market makers to rival DEXs on the same chains is what the next quarter will determine.

Ripple Begins Letting Go

Since 2017, Ripple has deployed over $550 million into XRP Ledger development, with most routes running through Ripple-controlled programmes. On February 26, the company announced a shift toward distributed funding. The new FinTech Builder Programme targets institutional-grade applications on the XRP Ledger, with mentorship and investor access from Dragonfly, Pantera, and Franklin Templeton. Community-driven microgrants will run through the XAO DAO, while university partnerships across Oxford, UC Berkeley, and Fundação Getulio Vargas in São Paulo support early-stage builders. A unified XRPL funding hub will connect all routes in one place.
‍

The context matters. DeFi deposits on the XRP Ledger dropped from $120 million to $49 million since July. The ledger's long-serving CTO departed in October. XRP staking is in validator voting but has not passed. Ripple is pushing for a broader ecosystem at a moment when the chain needs momentum, and the question is whether distributing control produces more builders or just more complexity.

Circle's Best Year and a Bigger Target

Circle's Q4 2025 results were substantial. USDC circulation reached $75.3 billion, up 72% year-over-year against a 40% internal target. On-chain transaction volume hit $11.9 trillion, a 247% annual increase. Adjusted EBITDA came in at $167 million, up 412% from Q4 2024.
‍

For 2026, the company is targeting 40% USDC growth. The Arc blockchain testnet, built specifically for regulated financial institutions with stablecoin-denominated fees and compliance features, has processed over 166 million transactions since October and is on track for mainnet launch later this year. Visa uses USDC for continuous settlement with US issuers. Intuit has a multi-year infrastructure partnership. Circle Payments Network has 55 enrolled financial institutions with 74 more in the pipeline.
‍

The primary risk is rate sensitivity. Around 56% of USDC reserve income is shared with Coinbase, and reserve yields decline as US Treasury rates fall. Q4 showed that volume growth can absorb some of that pressure, but the balance will tighten in a falling-rate environment.

Miners Are Becoming Infrastructure Companies

MARA Holdings announced a partnership with Starwood Capital Group on February 26 to convert select mining sites into hyperscale data centers. MARA contributes energy-rich sites with established grid connections; Starwood Digital Ventures handles construction, tenant sourcing, and operations. The platform targets one gigawatt of near-term IT capacity, with a pathway to 2.5 gigawatts. Sites are designed to switch between Bitcoin mining and AI compute depending on market conditions, giving MARA flexibility rather than forcing a full conversion.

MARA reported a $1.7 billion net loss in Q4, driven largely by unrealised Bitcoin writedowns, with revenues down 6% year-over-year. The Starwood deal follows the same logic covered here in prior weeks: CleanSpark acquiring 447 acres in Texas for hybrid mining-HPC use, and IREN announcing AI data center expansion alongside mining. The pattern is now the standard capital allocation strategy across listed miners, not an exception to it.

$864 Million, Institutions Still Writing Cheques

Crypto and blockchain companies raised $864 million across 63 deals in February, down 19.3% from January but still reflecting sustained interest. Sixteen deals exceeded $10 million. Capital concentrated in stablecoin infrastructure, institutional tooling, and compliant platforms.
‍

KPMG's Pulse of Fintech report noted that traditional financial institutions are now treating blockchain settlement as an operational replacement rather than an experiment. Japan's yen stablecoin segment also moved: Penguin Securities raised 2.8 billion JPY and JPYC secured 1.78 billion JPY. February's numbers show capital flowing toward businesses solving specific institutional problems, not those chasing retail speculation.

The Terraform Lawsuit Reaches Jane Street

Todd Snyder, the bankruptcy administrator winding down Terraform Labs, filed suit in Manhattan federal court against Jane Street on February 23. The complaint, heavily redacted, centres on a specific sequence: on May 7, 2022, Terraform quietly withdrew 150 million UST from the Curve 3pool. Within ten minutes, before any public disclosure, a wallet attributed to Jane Street pulled 85 million UST from the same pool.
‍

The lawsuit claims Jane Street held material non-public information through a private communication channel involving a former Terraform intern who had moved to Jane Street as a trader. Jane Street called the lawsuit "baseless" and noted that losses resulted from Terraform management's own fraud. That point is accurate but does not address the insider trading claim.

The case follows a $4 billion suit against Jump Trading filed in December 2025, which alleged a similar arrangement. Do Kwon received a 15-year sentence. The administrator's job is recovering assets for creditors, and Jane Street reported over $24 billion in profit in Q4 2025. The gap between those figures and what retail holders lost is what the court will now have to sit with.

Abu Dhabi Is Still Buying

SEC 13F filings published in mid-February showed Mubadala Investment Company and Al Warda Investments holding a combined position above $1 billion in BlackRock's iShares Bitcoin Trust as of December 31, 2025. Mubadala held approximately 12.7 million shares valued at $630 million; Al Warda held 8.2 million shares valued at $408 million. Mubadala added nearly four million shares during Q4, a 46% increase, while Bitcoin fell sharply.
‍

Sovereign funds do not make experimental bets. Their governance structures and reporting requirements make large speculative positions effectively impossible. The Abu Dhabi disclosures reflect a deliberate decision to build long-term Bitcoin exposure through regulated US products, the same framework applied to infrastructure, private equity, and commodities. Luxembourg's Intergenerational Sovereign Wealth Fund became the first European state fund to invest directly in Bitcoin earlier this year. The Qatar Investment Authority is reportedly building a dedicated digital assets team. The allocation decision and the drawdown are two separate things.

Where This Week Points

Eight stories, eight different angles on the same shift. Protocol governance is generating real revenue for the first time. Stablecoin issuers are posting quarterly results that beat targets by double digits. Miners are converting energy assets into AI infrastructure because the margins are better. Sovereign funds are adding Bitcoin during drawdowns, not cutting exposure.

The Jane Street lawsuit sits apart from all of that. It looks backward rather than forward. But it is part of the same maturation process. For crypto to function as a serious asset class, the failures that defined its worst periods need to be examined in court, with evidence and accountability, rather than recycled endlessly on social media. That process is now underway, four years after the fact. It is slow, but it is happening.
