Quick Breakdown: Upexi submits an SEC filing for a $1 billion shelf registration to expand Solana holdings and for general purposes. Shares (UPXI) fall 7.5% to $1.84 amid investor concerns over dilution and crypto volatility. The company ranks fourth among corporate Solana holders, with 2.1 million SOL valued at $262.3 million. ​ Upexi, a Nasdaq-listed firm that pivoted to a Solana treasury strategy in late April 2025, filed a $1 billion shelf registration with the U.S. Securities and Exchange Commission on December 23. The filing allows issuance of common stock, preferred stock, debt, warrants, and units over three years for working capital, research, debt repayment, and Solana accumulation. Shares closed down 7.54% at $1.84, reflecting market jitters despite an after-hours recovery to $1.92. New: @Solana treasury company @UpexiTreasury, which manages about 2M $SOL on its balance sheet, has filed a shelf registration with the SEC to raise up to $1B. pic.twitter.com/mlR7paJyWc — SolanaFloor (@SolanaFloor) December 24, 2025 The move signals renewed intent to grow its treasury, which has been stagnant since a July 23 purchase of 83,000 SOL that brought holdings to nearly 2 million tokens, worth $381 million at the time. Solana now trades at $123.75, down 57.5% from its January 2025 peak of $293.31, leaving Upexi with a 19% paper loss on its $262.3 million stash. CoinGecko ranks Upexi fourth among public firms, behind leaders that have embraced digital asset treasuries amid 2025’s crypto pullback.​ Treasury strategy fuels volatility Upexi’s shift from consumer products and e-commerce to Solana focus drove a 600% stock surge post-announcement, with unrealized gains offsetting business losses of $13.7 million. Purchases halted amid a broader market cooldown and doubts about the sustainability of the crypto treasury, yet the shelf filing hints at an aggressive resumption. A prior $500 million credit line in July supported buys, positioning Upexi for blockchain adoption if Solana rebounds. Revenue fell 39% to $15.81 million in 2025, underscoring reliance on crypto upside. Market reactions temper enthusiasm Investor response highlights risks: shelf offerings often dilute shares, and Solana’s 2025 slump eroded its treasury value from $525 million. Beta of -0.50 indicates lower volatility than the market, but 52-week gains of 96% mask recent slides. Meanwhile, the Solana blockchain successfully weathered a massive 6 terabits-per-second DDoS attack, maintaining total operational stability without any downtime or transaction delays. By contrasting this resilience with past outages and the struggles of rival networks, the text highlights how technological upgrades such as QUIC and stake-weighted quality of service have strengthened the system’s infrastructure.

XRP and solana ETFs continued to attract modest but steady inflows, underscoring selective investor demand. Ether Turns Red Again as Bitcoin ETFs Sink Further Risk appetite cooled further across crypto exchange-traded funds (ETFs) as the holiday-shortened week approached, with investors pulling more capital from bitcoin and ether while keeping a cautious bid for XRP and solana products. Bitcoin.com News logo Bitcoin ETFs posted a fourth consecutive day of outflows, while ether ETFs slipped back into the red. XRP and solana ETFs continued to attract modest but steady inflows, underscoring selective investor demand. Ether Turns Red Again as Bitcoin ETFs Sink Further Risk appetite cooled further across crypto exchange-traded funds (ETFs) as the holiday-shortened week approached, with investors pulling more capital from bitcoin and ether while keeping a cautious bid for XRP and solana products. Bitcoin spot ETFs recorded a net outflow of $188.64 million, extending their losing streak to four consecutive sessions. The pressure was concentrated in just four funds, led overwhelmingly by Blackrock’s IBIT, which alone shed $157.34 million. Fidelity’s FBTC followed with a $15.30 million outflow, while Grayscale’s GBTC saw $10.28 million exit. Bitwise’s BITB rounded out the day with a smaller $5.72 million outflow. Despite the continued withdrawals, trading activity remained active at $3.16 billion, and total net assets were largely unchanged at $114.29 billion. Ether ETFs also reversed course, returning to outflows after a brief rebound. The group posted a net exit of $95.53 million, driven primarily by Grayscale’s ETHE, which lost $50.89 million. Blackrock’s ETHA added to the pressure with a $25.04 million outflow. Smaller but notable exits were also seen on Bitwise’s ETHW at $13.98 million and Franklin’s EZET at $5.61 million. Total value traded dipped to just under $1 billion, while net assets held steady at $18.02 billion. XRP ETFs continued their steady run, albeit at a slower pace. The group added $8.19 million on the day, entirely driven by Franklin’s XRPZ. Trading volume came in at $12.41 million, with total net assets holding firm at $1.25 billion, suggesting investors remain comfortable maintaining exposure even as flows moderate Solana ETFs also stayed in positive territory, bringing in $4.20 million. Bitwise’s BSOL led with a $1.64 million inflow, followed closely by Grayscale’s GSOL at $1.46 million and Fidelity’s FSOL at $1.10 million. Trading activity reached $28.57 million, pushing total net assets up to $940.96 million as solana ETFs inch closer to the $1 billion milestone. As markets get set to close for the Christmas holiday, the year-end outlook for bitcoin and ether ETFs continue to look bleak with more capital departure. On the other hand, XRP and solana look to finish strong after their impressive debuts in 2025.

As Bitcoin $87,744.31 struggles to consolidate under its previous peak, seasoned analyst Peter Brandt suggests that the current market cycle is not yet complete. According to Brandt, the structure of cycles that span over several years may allow for a more severe pullback before a lasting bottom is formed. He hints at volatile and unsettling price movements in the short term, predicting that the next major bull peak could be delayed until around September 2029. This discussion reignites the debate on whether Bitcoin’s weakness presents an opportunity or a warning for altcoins. Contents Brandt’s Perspective on Market Bottom What Awaits the Altcoin Front? Brandt’s Perspective on Market Bottom Peter Brandt emphasizes that Bitcoin’s long-term charts indicate that cycles are completed over years rather than months, hinting that the current structure appears unfinished. He notes that the price remaining significantly below its recent peak and the lack of strong momentum return could indicate that the deep cleansing process in the market has not yet concluded. Brandt’s cautious stance is based on Bitcoin’s recurring pattern over the past 15 years. This behavioral pattern involves severe corrections following significant parabolic rises that wipe out excessive leverage and speculation, paving the way for a new cycle. This historical pattern leads the analyst to keep “worse case” scenarios on the table. In more extreme assumptions, Brandt points to the mid-20,000 dollar range as a potential cycle bottom, suggesting the risk of falling below 60,000 dollars should not be ignored if selling pressure accelerates. What Awaits the Altcoin Front? Bitcoin’s failure to maintain critical psychological levels and signals of market share softening direct some investors toward the potential for capital rotation. Historical cycles have shown relative performance increases in specific segments of altcoins while Bitcoin hovered in a horizontal range, bringing similar expectations back to the forefront. Ethereum $2,952.28, DeFi, tokenization, and their central roles in institutional experiments are frequently cited as potential beneficiaries. A scenario where Bitcoin lacks direction could see selected altcoin projects shine. On the other hand, analyst Benjamin Cowen highlights that a broad-based altcoin rally may not occur unless macroeconomic and monetary conditions are favorable. Cowen argues that investors lingering with expectations of a weak altcoin season could see these unmet expectations deferred to 2026. He adds that long-term wealth building is more about holding robust, quality assets rather than chasing speculative narratives. Currently, there is no clear consensus within the altcoin market. Asset managers like Bitwise believe that if liquidity conditions become favorable, Bitcoin, Ethereum, and Solana could reach new peaks in 2026. Experts like Arthur Hayes, however, describe the altcoin season not as a one-time event but as an ongoing process driven by narrative shifts and capital flows changing waves.

The latest Builder’s Block brings a dense batch of arbitrum updates, spanning protocol post-mortems, new learning content, and emerging economic debates across the ecosystem. Summary Technical post-mortem on Prysm Mainnet Learn and build with Stylus, WASM, and oracles Workshops on agentic payment flows and Solana migration Ecosystem highlights and economic debates Governance, proposals, and community discussions Closing notes from Builder’s Block 008 Technical post-mortem on Prysm Mainnet The Arbitrum Foundation released a detailed analysis of the recent Prysm Mainnet “Fusaka” incident. The post-mortem explains the technical root cause, how it affected validator and network participation, and the specific mitigation steps taken. Moreover, the report outlines the patches shipped in v7.0.1+, designed to prevent a similar disruption. These changes strengthen client robustness while keeping compatibility with Ethereum’s upgrade path. Learn and build with Stylus, WASM, and oracles New “Learn Build” resources focus on helping developers deepen their skills across the Arbitrum tech stack. A long-form explainer examines how Stylus leverages WebAssembly to overcome EVM limits and improve performance. This deep dive shows how WASM can unlock more efficient computation and lower gas costs while preserving full interoperability with existing EVM smart contracts. That said, the article also stresses careful benchmarking when migrating high-value workloads. Another piece delivers an optimized RedStone oracles technical breakdown. It details the redstone oracle integration with Arbitrum Stylus and how oracle data can be processed with lower latency and reduced costs for on-chain applications. Developers can also access a complete five-part course dedicated to Arbitrum Stylus. The YouTube series includes an introduction to Stylus, a speedrun, a Uniswap fork implemented in Stylus, a module on Stylus data types, and an overview of the Stylus CLI. Workshops on agentic payment flows and Solana migration A new workshop on agentic payment flows targets teams building for x402 and AP2. In this session, CapxAI and Arbitrum walk through Agentic Payment Flows and Private AI Inference, illustrating how programmable agents can route and protect payments on L2. Moreover, the ecosystem is pushing cross-chain growth with resources for teams that want to migrate solana applications to Ethereum liquidity. The StylusPort handbook and CLI/MCP assistant help Rust-based projects move to Arbitrum Stylus while keeping familiar tools. Ecosystem highlights and economic debates The latest arbitrum ecosystem announcements highlight fresh launches and notable community threads. A key feature examines l2 vs l1 economics, comparing fundamental differences between Ethereum L1 and L2 models. This analysis covers long-term sustainability, sequencer revenue structures, and data availability costs. However, it also raises open questions about how fee markets and profit-sharing will evolve as L2 adoption accelerates in 2025. Another technical talk explores confidential payments lending and sealed-bid lending auctions on Arbitrum. The discussion explains how confidential stablecoins and on-chain auction designs can be combined to protect user privacy while preserving transparent settlement. An end-of-year event titled “Meet Steven Goldfeder” features the CEO of Offchain Labs. The session, available both in person and online, provides community members with a chance to hear directly about Arbitrum’s roadmap and recent milestones. Governance, proposals, and community discussions On the governance and research side, the community is discussing Vitalik Buterin’s ideas for trustless gas prediction markets. This architecture aims to improve fee estimation and enhance block market efficiency on L2s through market-based forecasts. In parallel, an AIP proposes activating ArbOS 51, also known as “Dia”. The constitutional change would align with Ethereum’s Fusaka upgrade, refine gas pricing logic, and ship critical node optimizations to strengthen the rollup’s performance. Another live proposal, “Stablecoin Fast Lane”, suggests a specialized transaction path similar to TimeBoost, tuned for stablecoin payments. Moreover, the design targets reduced latency for financial transactions by prioritizing time-sensitive flows without undermining general-purpose usage. These discussions, combined with continuous arbitrum updates from the Foundation and community, show how governance, research, and infrastructure upgrades are converging to optimize the L2 stack. Closing notes from Builder’s Block 008 Builder’s Block #008 closes with a reminder to keep experimenting across the stack, from Stylus WASM performance to new oracle pipelines and confidential finance primitives. Overall, the latest edition underlines Arbitrum’s push for performance, security, and developer-focused tooling across the ecosystem.
