MetaMask announced a partnership with the Stellar Development Foundation to make Stellar a default network in both its mobile app and browser-extension wallet, with the integration going live on the day of the announcement. All existing MetaMask accounts will automatically derive Stellar addresses from their existing seed phrases with no extra setup, and existing Stellar users can import their original seed phrases to migrate.

MetaMask Chief Product Officer Gal Eldar framed the integration as part of the wallet's "Open Money" strategy, saying the goal is for the same payment infrastructure to serve all users. The default-network placement removes the manual network-addition step that non-EVM chains have typically required in MetaMask.

Stellar addresses are deterministically derived from users' existing mnemonics rather than requiring a new seed phrase, and the change applies to both mobile and extension clients. The announcement did not disclose on-chain volume targets for the integration.

Moody's Ratings assigned an A2 long-term deposit rating and a P-1 short-term deposit rating to Ripple USD (RLUSD), the dollar-backed stablecoin issued by Ripple subsidiary Standard Custody & Trust Company, the agency said on Tuesday. A2 is the sixth-highest long-term grade on Moody's scale and P-1 is its top short-term grade.

Moody's said the ratings reflect the quality of RLUSD's reserves, which are held mainly in Treasury bills, other short-term U.S. government assets and cash, most of it with custodian BNY. The action gives the stablecoin an independent credit assessment at a time when Ripple is pitching it to institutional users.

Moody's said RLUSD targets 103% coverage of tokens in circulation, and eligible institutional holders can redeem at par within two business days; the agency also flagged that Standard Custody is not a bankruptcy-remote entity and that RLUSD holders do not currently have a direct ownership interest in the reserves. The ratings were requested by the issuer, and Moody's noted that the GENIUS Act, due to take effect in 2027, will exclude required reserves from an issuer's bankruptcy estate.

BNY (Bank of New York Mellon) has begun offering custody services for XRP, according to CryptoSlate, extending its institutional digital-asset custody coverage to the asset. The offering currently exists in only one rollout type, a narrower scope than a full multi-model launch.

The report frames the addition as an expansion of institutional custody support for XRP, giving bank-grade custody coverage to an asset that previously sat outside this particular channel.

The rollout is limited to a single custody type, which tempers the scope of the announcement even as it adds a major bank to XRP's custody line-up.

Iron Fish said on Oct. 28 that it is investigating abnormal minting of wIRON, the wrapped version of its token on Base, and has asked cross-chain bridge provider ChainPort to carry out an urgent review. The team told users not to buy wIRON on Base or use the related bridge until further notice because full 1:1 reserve backing can no longer be guaranteed.

By its own statement, Iron Fish can no longer guarantee that wIRON on Base is fully backed 1:1, which puts the redemption value of the wrapped asset in question while the investigation continues.

Iron Fish said it will publish further updates once the facts are confirmed; the cause of the abnormal minting has not been disclosed. The advisory covers both buying wIRON on Base and using the associated bridge.

TechCrunch reported on October 27 that large-scale conversions of convertible notes have revealed the full extent of Amazon's ownership stake in Anthropic, putting the cloud giant in line to earn far more from the AI lab's planned IPO than venture investors. Amazon structured much of its investment as convertible notes — debt that converts into shares upon an IPO or sale — rather than taking stock up front.

The disclosures indicate that a corporate backer, not traditional venture firms, holds the largest single financial upside in one of the sector's most anticipated listings. Venture investors including Menlo Ventures, Sequoia, Sound Ventures and Spark Capital are still expected to see billions in returns, according to the report.

Amazon has invested billions in Anthropic beyond its initial commitment, a $4 billion investment the company said it had completed. The report attributes the unusually large gap between corporate and venture returns to Anthropic's sheer size, since lead venture investors in a typical tech IPO hold double-digit percentage stakes.

SK Hynix reported record third-quarter results on Wednesday, with revenue of 104.6 trillion won (up 328% year over year) and operating profit of 83.3 trillion won (up 632%), an 80% operating margin — the first time its quarterly sales topped 100 trillion won and above the 77.5 trillion won operating profit analysts surveyed by Bloomberg had expected. The company said demand for memory will keep outrunning supply through 2030 and that its DRAM and HBM volumes through 2029 are effectively sold out.

The disclosure gives hard earnings data on how long the AI memory shortage is expected to last: SK Hynix says customer volume requirements are more than double what it can supply today, with long-term agreements covering more than half of its 2027 and 2028 capacity. CEO Kwak Noh-Jung attributed confidence in continued AI spending to cloud customers reporting 30% to 80% year-over-year revenue growth and backlogs up two- to five-fold.

Net income was 39.8 trillion won, up 216% year over year but down 58% from the second quarter; CFO Kim Woo-hyun said the gap came from 32.6 trillion won of net non-operating expenses, led by an 11.6 trillion won currency loss and a 22.9 trillion won investment valuation loss. Long-term agreements with 14 key customers including global cloud providers cover more than 50% of 2027-2028 capacity, typically run five years, allow prices to move within an agreed range and include safeguards such as deposits; SK Hynix expects investment to rise significantly in 2027 as the first phase of its Yongin complex enters full-scale operation.

JPMorgan Chase, Coca-Cola, Dell Technologies, AMD, Adobe, Applied Materials and Sandisk were added to OKXICE TSV's list of objecting issuers in a notice dated Tuesday (Oct. 27), bringing the total to 33 from 26 a day earlier. Under the SEC's innovation exemption, a timely written objection bars the venue from listing a third-party tokenized version of a company's stock.

Each timely objection legally removes those shares from the venue's listable universe, so the rapid escalation from nine objectors on Oct. 15 to 33 directly narrows a high-profile tokenized-equity product. JPMorgan is the third major bank to object, after Goldman Sachs and Wells Fargo.

The list stood at 16 on Oct. 19 and 22 on Oct. 23; earlier objectors include Microsoft, Alphabet, Goldman Sachs, Wells Fargo, Intel and Oracle, while Nvidia, Tesla, Apple and Amazon have not objected so far. The notices have not disclosed the companies' reasons, and an objection applies only to that venue.

Robinhood reported record revenue of $1.4 billion alongside a 14% drop in profit, with the results tied to losses in its own portfolio holdings. The online brokerage's shares came under pressure after the report, falling about 6.6% in pre-market trading from a $95 close on October 27 to $88.

The quarter shows Robinhood's top line expanding even as profitability weakens, and the stock reaction indicates investors are weighing the profit miss over the record revenue.

Crypto transaction revenue fell 55% year-over-year to $120 million in the third quarter ended September 30, though it still topped Street forecasts. Coverage of the results also pointed to declining interest income and rising expenses weighing on profit despite record trading activity in stocks, options and prediction markets.

DailyCoin published an analysis arguing that a third-party vendor incident at Coinbase exposes the security weaknesses contractors can introduce to exchange private-key and customer infrastructure. Search excerpts describe the vendor as analytics provider Amplitude, which experienced a security incident affecting a small subset of Coinbase customer contact data, while Coinbase said it found no evidence of unauthorized access to its systems.

The episode highlights how third-party vendors can become an indirect exposure path for exchange customer data, even when the exchange says its own systems were not breached.

The described exposure involved customer contact data rather than private keys, and Coinbase said funds were unaffected. No loss figure or confirmed private-key compromise has been disclosed.

Kamino, a lending and liquidity protocol on Solana, has launched USDC loans collateralized by Backpack-issued tokenized stocks, letting borrowers draw dollar liquidity against tokenized equity positions instead of selling them. The product marks a new use of tokenized equities as DeFi loan collateral.

The launch makes tokenized equities usable as collateral inside an onchain credit market, extending real-world asset integration and cross-market composability on Solana. It also puts equity-price and off-market-hours risk directly into a DeFi lending pool.

Backpack issues its tokenized equities through Backpack Securities, with Sunrise handling custody and token issuance, and the tokens can be redeemed for underlying value — a mechanism described as creating a price floor relative to the represented asset. Kamino positions itself as an open-source credit and liquidity protocol on Solana that supports borrowing against onchain collateral through transparent markets.

Microsoft said it recorded $10 billion in revenue from commercial arrangements with OpenAI, including revenue-sharing payments, in the quarter ended September 30. The disclosure quantifies how much Microsoft's top line currently depends on the partnership.

The figure shows the partnership remains a large, direct contributor to Microsoft's reported revenue, not only a strategic investment.

The $10 billion covers commercial arrangements with OpenAI including revenue-sharing payments for the quarter ending September 30. Microsoft has not signed off on OpenAI's proposed changes to the revenue-share terms.
