Polygon Labs has completed its acquisition of Coinme, and its Open Money Stack is now a US-regulated payments platform that supports USD inflows via bank transfer, card, or cash deposits for on-chain settlement. Named clients include Tazapay, Mesh, Toku, and Kira.

The deal folds regulated US money-transmission capability into Polygon's payments stack, giving the Open Money Stack a fiat on-ramp channel through which bank, card, or cash dollars can be moved on-chain for settlement.

BlockBeats reported that the platform covers 48 US states, holds 37 state-level money transmitter licenses plus 11 applicable exemptions, and is registered with FinCEN as a money services business; the first customers use it for cross-border business payments, account top-ups, global payroll, and USD services.

Nasdaq-listed Evernorth has selected Ripple, Kraken, Coinbase and BitGo as its first institutional partners to deploy roughly 473 million XRP, worth about $648 million at current prices, through institutional strategies starting in the fourth quarter. The company said it will later expand into lending on the XRP Ledger and on-chain DeFi strategies, with the deployment led by former Coinbase Asset Management co-CIO Hugo Jeandesboz.

A publicly listed treasury company is naming regulated exchanges and custodians to actively put a nine-figure XRP reserve to work rather than simply holding it, which ties a large XRP position into established institutional custody and trading venues.

The plan is a stated intention to deploy from the fourth quarter onward, not a completed deployment. The 473 million XRP figure is valued at approximately $648 million at current prices, and the XRP Ledger lending and on-chain DeFi expansion is described as a future step.

Payward, the parent company of crypto exchange Kraken, agreed to acquire Lithuania-based Saldo Bank for an undisclosed amount, a deal that would give it a European Union banking license. The acquisition is subject to regulatory approval and is expected to close in 2027.

The deal would let Payward offer EU customers interest-bearing deposits, loans, card services and euro payments, expanding it beyond crypto trading, and would make it the first crypto firm to buy a European bank, according to the Financial Times.

Saldo Bank had €163.9 million (about $180 million) in total assets at the end of 2025, up 22.7% year over year, and is licensed in Lithuania, Finland, Sweden and Germany with a passport to operate in the Netherlands; it offers deposits, consumer and business loans and payment services. Payward said its banking business has already originated more than $2 billion in loans and holds a Federal Reserve limited-purpose master account and an electronic money institution license in Ireland.

Ledger asked resellers and distributors in Indonesia, Singapore, Thailand, the Philippines, Vietnam, Malaysia and Hong Kong to suspend sales and take its hardware wallets off the shelves while it investigates suspected device tampering, the company said in a post on X on Tuesday. The request expands earlier stop-sale and shipment-suspension measures against regional reseller CryptoBilis, an investigation made public on Oct 9.

The move removes Ledger devices from retail shelves across a region and puts the integrity of the hardware-wallet supply chain, a core assumption of self-custody, under scrutiny. In Germany, MediaMarkt Saturn stopped selling Ledger devices in stores and online with Ledger's agreement after a customer reported an implant, though no funds were lost.

Ledger's Donjon security team found the implant reads the 24-word recovery phrase from the device's screen during setup and sends it out over LTE; anyone holding that phrase can restore the wallet and move its funds. Onchain investigator Specter has traced more than $86 million in suspected thefts, a figure Ledger says it has not verified.

Science Corporation, the neurotech company led by former Neuralink president and co-founder Max Hodak, has implanted its PRIMA vision-restoring chip in its first patient with Stargardt disease. Hodak announced the implant on stage at TechCrunch Disrupt, describing the PRIMA work as part of the company's path toward a novel brain-computer interface (BCI).

It is the first human implant of PRIMA in a Stargardt disease patient, a concrete milestone for Science Corporation's neurotech program. Hodak framed the implant as a step along the company's longer-term BCI ambitions.

The announcement covers a single patient, and Hodak presented it at TechCrunch Disrupt rather than through a peer-reviewed publication. Science Corporation has separately raised a $230 million Series C round, disclosed in March 2026, as it pushes to bring its brain implant to patients.

Strategy’s USD Cash fell 60% from $1.61 billion on August 30 to $640.5 million on October 11, according to the company’s latest disclosure this week. Most of the spending went to buybacks of STRC, its high-yield dividend preferred stock, which had briefly collapsed to $71.25 from a $90–100.03 offering range.

The buybacks consumed cash that Strategy had mostly raised by diluting MSTR common shareholders, and at the disclosed pace its USD Cash would run out in roughly four weeks if not topped up. The company is the largest corporate bitcoin treasury holder, so its dollar liquidity bears on how much room it has to keep accumulating BTC.

Strategy’s August USD Cash figure included expected, not-yet-settled stock sale proceeds, which the company footnoted. A separate “USD Reserve,” earmarked for bond coupons and dividends, stood at $4.88 billion on October 11, down from $5.10 billion on August 30 — a combined decline of about 18%. Strategy’s board doubled the STRC buyback authorization to $2 billion in September, with just $354.8 million of that remaining as of October 11.

Bitcoin dropped below $82,000 after a hotter-than-expected core CPI reading renewed expectations that the Federal Reserve may raise interest rates, The Block reported on Oct. 14. The decline followed the release of the inflation data, which pointed to firmer underlying price pressures.

Rate expectations are a primary channel through which macro data hits risk-asset pricing, and the move shows bitcoin trading in line with that sensitivity. Bloomberg data cited by Livemint showed that in 8 of the last 10 Fed hikes, bitcoin was lower a month later.

Core CPI tracks consumer price changes while excluding food and energy, which tend to be more volatile. The report was published on Oct. 14.

Coinbase published a blog post on Tuesday urging Bitcoin developers to begin quantum-resistance preparations immediately, warning that consensus changes and ecosystem migrations "can take years." The exchange, which says it custodies roughly 5% of all Bitcoin, laid out technical requirements including support for a flexible "container" design such as BIP-360, a staged "1-of-2" classical-plus-quantum spending path, compatibility with the MPC key-splitting used by custodians, and separate governance for dormant and Satoshi-era coins.

The post is positioned as a set of requirements from one of the network's largest stakeholders rather than a mandate, and it is a proposal rather than a deployed upgrade or consensus change. Coinbase argues that waiting for a cryptographically relevant quantum computer to be announced would leave too little time to respond.

Coinbase stressed that any transition would need to protect both existing and newly created coins, fit Bitcoin's limited block space, work for ordinary wallets and institutional custody alike, and offer a migration path for coins that never move. It said dormant, lost, or exposed coins including Satoshi-era holdings are a separate governance problem, and cautioned that any rescue mechanism must itself be quantum-safe so that an attacker with only an exposed public key could not exploit it.

DriveWealth, a brokerage-as-a-service platform, announced a partnership with Ripple to integrate blockchain capabilities — stablecoin settlement, payments, custody and prime brokerage — into its global investment infrastructure. The collaboration focuses first on integrating Ripple's stablecoin infrastructure in Europe, with plans to extend to the United States and other markets.

DriveWealth supplies API-based trading infrastructure to banks, fintechs, broker-dealers and consumer brands, so the tie-up would push an existing enterprise stablecoin into brokerage settlement and cross-border funding rails if implemented. The arrangement was announced as a plan rather than a completed integration.

The stated scope includes access to Ripple Payments to streamline cross-border fund inflows, digital asset custody in Europe with later expansion to other markets, and exploration of institutional business such as equities financing through Ripple Prime. No timeline, transaction volumes or commercial terms were disclosed.

An open letter published Tuesday asks AI labs to "airgap" cyber-capable models by default — physically disconnecting them from any outside network. More than 400 scientists signed it, including AI pioneers Geoffrey Hinton and Yoshua Bengio, and the count reached 450 signatures by Wednesday, including UC Berkeley's Stuart Russell and MIT's Ron Rivest, co-inventor of RSA.

The letter is non-binding and carries no immediate enforceable effect on labs, but its signatories warn that without prompt changes to AI development and deployment practices, such incidents will keep occurring and future ones will be far more damaging to exposed critical infrastructure.

Under the proposal, airgapping would be the default at least initially for any model with serious hacking skills, while anything needing more freedom, such as internet access, would follow standards set by a new international body created with governments that would also collect containment-failure reports and eventually make them public. The industry's own response has largely pointed the other way: in August, OpenAI President Greg Brockman cited his company's breach in an essay urging every security team to deploy AI agents immediately.

Anthropic published a post titled "Preparing for the 2026 US midterms" setting out how its AI models will be governed during the election period, covering election-integrity policy, usage limits on political campaigning, and misinformation safeguards.

The post commits a leading frontier AI lab to concrete behavioral obligations around a US election cycle, although these are voluntary, self-imposed measures rather than regulatory requirements.

The election guidance sits alongside Anthropic's annual Usage Policy update, which the company says it publishes each year in response to evolving model capabilities and customer feedback.
