Solflare is integrating lending yields directly into the wallet—DeFi is entering the default interface. Fewer steps are needed, but risk disclosures must keep pace. ① Solflare has launched Earn, allowing users to supply USDC to the Kamino lending market directly within their wallet. This consolidates what previously required switching to external apps into a unified wallet experience across mobile, web, and browser extensions. ② This reduces user friction—eliminating the need to search for entry points, identify websites, and repeatedly connect. For underlying protocols, wallets now serve as distribution channels to reach stablecoin holders. ③ However, adding a yield button doesn’t change the economic nature of the funds: USDC is deposited into a lending contract, where rates fluctuate with market conditions and should not be interpreted as fixed interest or bank deposits. ④ Product disclosures can typically be dismissed quickly and may take longer during high traffic. Therefore, “no lock-up period” and “instant access under all circumstances” must be understood separately—liquidity risk and contract risk remain the user’s responsibility. My own view: When wallets integrate yield features, clear risk communication becomes a key product differentiator. I prefer interfaces that transparently explain where funds go, exit conditions, and why yields change—not just those that amplify APY numbers. @Solana_zh @solana @solflare @kamino

Phantom brings prediction markets to U.S. users, changing the value of the wallet entry point. Users expressing opinions and completing trades are now appearing on the same page. ① Phantom is gradually rolling out prediction markets powered by Kalshi to eligible U.S. users, covering short-term price movements of select crypto assets, sports, and real-world events—with direct access integrated into the existing app. ② For the product, this extends users’ focus from “what assets do I hold?” to “what outcomes do I believe in?” Existing balances and usage habits reduce the friction of trying new trading scenarios. ③ However, it’s essential to understand the business boundaries: account approval, due diligence, and trade execution are handled by Kalshi. Adding an entry point does not mean all aspects of these markets become on-chain activities on Solana. ④ “For U.S. users” does not mean unrestricted access—availability varies by market category, and event contracts may result in total loss of investment; short-term markets can amplify the impulse to place frequent bets. My own assessment: This demonstrates the value of distribution entry points—and has made me more attentive to whether the product helps users understand settlement rules. There remains a significant gap between predicting a single event and building sustainable trading advantages. NFA / DYOR @Solana_zh @solana @phantom @Kalshi

Google’s custody initiatives are worth studying more than the phrase “big tech endorsement.” Before institutions enter on-chain, they must first resolve who can move funds. ① Solana officially disclosed that Google has launched a multi-party computation (MPC) custody system for institutions, currently in private preview with major financial institutions, with a commercial launch targeted for early 2027. At this stage, it should not be portrayed as fully commercially available. ② These systems handle digital asset control: how keys are managed, how signing permissions are allocated, and how critical operations are executed. For institutions, even if on-chain transfers are fast enough, internal authorization and security protocols still determine adoption speed. ③ I’m more interested in whether it can integrate into existing enterprise workflows. Holding tokens on the balance sheet and incorporating tokens into daily operations are two entirely different levels of complexity—the latter requires a continuously available operational framework. ④ Private preview information does not mean client funds have been massively migrated, nor does it imply Alphabet has purchased SOL. The actual scope of support, liability allocation, commercial terms, and user scale remain to be disclosed. My own assessment: Institutional adoption is often driven by these less glamorous capabilities. Once custody, approval, and operational recovery are properly addressed, financial products can operate sustainably. I’m watching this path closely—but I separate product progress from market sentiment. NFA / DYOR @Solana_zh @solana @Google

TVL has grown for 12 consecutive quarters, yet gross profit has declined: DeFi shouldn’t be judged solely by deposit rankings. Sanctum’s latest quarterly report is worth examining more closely than just “record-breaking scale.” ① On October 23, Sanctum released its Q3 2026 report. The project disclosed that TVL reached approximately 18.6 million SOL at quarter-end, marking the 12th consecutive quarter of growth. Note that this reflects the scale at quarter-end, not new deposits added this week. ② However, another set of figures shows the opposite trend: gross profit declined by approximately 6.2% quarter-over-quarter in USD terms and by about 16.3% in SOL terms. The same business, measured in a different unit, reveals a different magnitude of change. ③ The project attributes the decline primarily to a one-time revenue spike from large LST redemptions in the prior quarter; Solana Compass further notes that this quarter also included a significant one-time redemption. Therefore, when evaluating profitability, it’s essential to distinguish between episodic and sustainable income. ④ TVL growth does not immediately translate into proportional revenue; gross profit is not net profit, nor does it directly indicate token holder returns. These figures are based on project disclosures and reporting; I have not independently verified them. My own assessment: This report has shifted my focus toward “how much sustainable income each unit of assets generates.” While growth in scale is important, if revenue relies heavily on occasional large transactions, sustainability must be assessed more cautiously. Next quarter, I’ll closely monitor whether new assets are being retained and whether the business has genuinely improved after excluding episodic income. NFA / DYOR @Solana_zh @solana @sanctumso

Staking ratio reaches 69%; validator operational conditions should also come into focus. Bitwise’s new report reminds me that network security must consider both capital and operational conditions. ① On October 20, Bitwise released its Q4 2026 Staking Report. Here, Q4 refers to the report version; the Solana section primarily describes conditions at the end of the third quarter and should not be interpreted as an immediate measurement after Alpenglow’s launch. ② According to the report’s metrics, approximately 69% of supply is staked, with a gross yield of 5.99%, down from the previous 6.38%. Gross yield is not the net return individual users receive, nor is it the current platform-promised APY. ③ The same report notes a decline in the number of validators from 696 to 659, and discusses pressure from operational costs. When interpreting such data, it’s important to distinguish between validator records, active voting accounts, and independent operational entities to avoid conflating different metrics. ④ These end-of-quarter figures occurred prior to the activation of the new consensus, so they cannot be used to assert whether Alpenglow has improved or worsened current validator profitability; post-upgrade costs and participation levels require new data. My own view: A secure network requires sufficient staking as well as sustainable participation across operators of all scales. I will monitor subsequent staking concentration, operational barriers, and client distribution, avoiding judgments of network health based solely on a single yield metric.

557 million stablecoin transfers are striking, but payment demand needs to be viewed from multiple angles. ① On October 18, Solana officially stated on X that stablecoin transfer volume reached 557 million in September, a 33% month-over-month increase, averaging approximately 18.6 million transfers per day. First, clarify the unit: this is count of transfers, not USD value. ② High-frequency transfers can occur in various scenarios such as trading, market making, and automated fund management. Even if the statistics are accurate, further differentiation is needed between retail payments, institutional fund movements, and automated machine activity. ③ The September data was disclosed this week and should not be presented as real-time October performance; nor should the 557 million transfers be interpreted as 557 million users. A single business transaction may involve multiple transfers, and the same address may repeatedly perform operations. ④ The materials reviewed so far do not provide sufficient detail for independent replication of the methodology. Therefore, rankings and growth rates should be attributed as “officially disclosed,” and independent verification remains pending; a secondary report cannot substitute for a data audit. My own assessment: I accept stablecoin activity as a useful entry point for observation, but I will continue seeking adjusted values, accounts with repeated usage, and real merchant case studies. Only by breaking down this single growth curve into distinct demand categories can we assess its sustainability. NFA / DYOR @Solana_zh @solana @SolanaFndn

BAYC IP launches Solana-based cards; next, see if collectors become players. Mudwater integrates physical, digital collectibles, and gaming into a single product initiative. ① On October 18 (Beijing Time), Yuga Labs introduced Mudwater: a physical and digital card project centered on the BAYC IP, with digital assets built on Solana. The announcement mentioned 120 artwork pieces and a release design of 10,000 boxes, each containing 24 packs. ② What’s noteworthy here is how an existing IP organizes new collectible and gaming experiences—but this does not imply a migration of existing BAYC NFTs or ApeCoin as a whole. Selecting a network for a single product is distinct from migrating an entire ecosystem. ③ The physical-to-digital conversion mechanism described in the product materials has yet to be launched. The cards used in current game demos are not equivalent to all on-chain cards held by players being fully integrated into gameplay. ④ Fees must be analyzed separately: the 2.5% reflection mentioned in the materials and the separately listed 2.5% royalty cannot be combined and misinterpreted as a total transaction cost of only 2.5%. Collectibles also carry risks of low trading volume and difficulty exiting positions. My own view: An IP can attract initial attention, but sustained engagement depends on content and gameplay. I’ll closely track delivery progress, replayability, and actual player retention to determine whether this hype can transform into a genuinely enjoyable, repeat-play product.

After on-chain payments, bookkeeping is still required—Altitude has integrated updates directly into accounting workflows. Whether categorization suggestions save time is a small but noteworthy factor in enterprise adoption. ① On October 21, Altitude introduced the Accounting Suggestion Engine, which recommends transaction types and accounting categories based on similar counterparties, amounts, and historical posting records, with future integration support for QuickBooks and Xero. ② While on-chain transactions show fund movements, businesses still need to determine whether they represent vendor payments, customer receipts, or internal transfers. Clarity in reconciliation and classification directly impacts whether finance teams will continue using the system. ③ This feature is designed as a suggestion tool requiring human confirmation—not as an automated solution for all accounting tasks. Historical records may contain errors or be irrelevant to new transactions; users must still review the underlying business context. ④ The official documentation preserves manual editing paths and retains users’ saved selections. Reducing redundant data entry and preventing sync errors is more meaningful to validate than broadly labeling it an “AI finance agent.” My own assessment: This is an enterprise application direction I’m willing to track. Its impact should be measured by how many repetitive tasks are saved per month, whether classification errors decrease, and whether financial closing accelerates—these require real customer data to answer. It’s premature to draw conclusions about the product at this stage. @Solana_zh @solana @altitude

A QR code connects multiple payment pathways, but stablecoin payments still require the invoice step. Altitude demonstrates the X9.150 solution, focusing on how payment requests are reliably interpreted. ① On October 19, Altitude introduced on X a QR code payment demo based on X9.150: linking different settlement pathways—such as FedNow, RTP, or Solana USDC—to the same payment request. ② Its product demonstration illustrates the workflow: identifying a signed request, verifying its content, obtaining user confirmation for payment, and then updating the invoice with the payment status. For businesses, knowing which invoice corresponds to which payment is as critical as making the payment itself. ③ Signature verification provides evidence of origin and content integrity, but it cannot alone confirm the authenticity of the transaction context, delivery of goods, or reasonableness of each charge. Business-level review still has its essential role. ④ This should currently be understood as a proof-of-concept and demonstration—not as evidence that all banks support it or merchants have fully enabled it. The official scope of availability, fees, failure handling, and general rollout timeline remain to be disclosed. My own assessment: I’m keen to follow these payment workflow improvements. Whether businesses adopt them will depend on whether verification, authorization, payment, and reconciliation can be seamlessly connected. Only when the entire process becomes truly effortless will on-chain settlement become a practical everyday tool. @Solana_zh @solana @altitude

Helius expands pre-confirmation permissions; earlier signals require clearer state boundaries. Low-latency tools can improve responsiveness, but the product must know when to consider an action complete. ① On October 17 (Beijing Time), Helius announced that its pre-confirmation feature is now available to all paid plans, adding four new filtering capabilities: source, signer, signatures, and instructions. This week’s update expands both availability and filtering functionality. ② For applications that need to track specific signers or instructions, filtering reduces irrelevant messages, enabling programs to receive relevant signals earlier. However, this feature is not universally available on free plans, nor is it new this week. ③ Documentation distinguishes between stages of different signal sources: notifications after local execution differ in contained state information from those received before execution. Developers cannot ignore the specific meaning of signals merely because they arrive earlier. ④ Pre-confirmation does not equal final settlement. Application design must account for scope coverage, potential duplicate notifications, connection recovery, and the eventual final state—especially when displaying balances or delivering assets. My own assessment: The value of such features depends on whether the business can correctly leverage the early notice. I’d prefer to see clear “pending confirmation” indicators and robust error recovery, avoiding user confusion caused by interfaces that appear too fast and imply irreversibility. @Solana_zh @solana @Helius
