Cardano’s ADA Token Now Accepted at Spar Supermarkets in Switzerland

0

In brief

  • Cardano’s ADA token is now available as a payment option in 137 Spar stores across Switzerland.
  • The brick-and-mortar retail payments option is available through Cardano’s integration with fiat on- and off- ramp platform DFX.swiss.
  • The partnership is “planting seeds” for a financial ecosystem in which “paying with ADA is as natural as paying with a card,” the Cardano Foundation’s CEO said.

Cardano’s ADA token is now available as a payment option in Spar supermarkets across Switzerland, following the blockchain’s integration with fiat on- and off-ramp platform DFX.swiss.

The integration leverages DFX.swiss’ crypto payment standard Open Crypto Pay, already used to enable payments in cryptocurrencies including Bitcoin, Ethereum, and the USDC, USDT and DAI stablecoins.

Open Crypto Pay enables Cardano users to spend ADA tokens from native wallets to be used directly at the checkout for payment in Swiss Spar stores, by scanning a QR code. Stores receive payment in Swiss francs, “regardless of the cryptocurrency the customer paid in,” according to the Open Crypto Pay website.

The platform does not implement specific double-spend protection for brick-and-mortar merchants, calling it a “theoretical issue” as unlikely given the technical complexity and ease with which other methods of non-payment, such as “leaving a store without paying,” can be accomplished.

So far, 137 Spar supermarkets across Switzerland and neighboring Lichtenstein can accept payments using Open Crypto Pay—though according to a map on its website, stores in Geneva, Swiss capital Bern, and Davos, which hosts the World Economic Forum, have yet to be onboarded.

Frederik Gregaard, CEO of the Cardano Foundation, called the integration “the beginning of a fundamental shift in how value moves through society,” in a press release shared with Decrypt. He added that the partnership is “planting seeds” for a financial ecosystem in which “paying with ADA is as natural as paying with a card.”

Switzerland and crypto

Switzerland has gained a reputation as an early adopter of crypto, with some 350 businesses in the city of Lugano now accepting Bitcoin for payment as of December 2025.

While a citizen-led initiative has campaigned for an amendment to the Swiss Constitution to allow the country’s central bank to add Bitcoin to its reserves, the Swiss National Bank remains ambivalent about the prospect.

In April 2025, the bank’s chairman Martin Schlegel rejected the idea, citing crypto’s volatility and market liquidity as concerns. “Cryptocurrency cannot currently fulfill the requirements for our currency reserves,” he added.

CLSK sold one of its highest proportions of mined BTC during February.

0

CleanSpark (CLSK), a U.S.-based bitcoin mining company that operates large-scale data centers, sold almost all the bitcoin it produced last month to generate cash for an expansion into artificial intelligence (AI) and high-performance computing (HPC).

The Nasdaq-listed miner produced 568 BTC in February and sold 553 BTC, roughly 97%, according to its latest operational update. The sales generated about $36.65 million in proceeds at an average price of $66,279 per bitcoin, one of the highest production-to-sales ratios the company has reported.

The sale reflects a broader trend among bitcoin miners pivoting toward AI and HPC, with companies increasingly selling either new production or reducing their balance-sheet holdings to help fund new data center and infrastructure development.

CleanSpark still maintains a sizable treasury. As of Feb. 28, it held 13,363 BTC, with 1,086 BTC pledged as collateral or recorded as receivables related to derivative transactions.

Operationally, the company continues to scale its mining platform. CleanSpark reported 50 EH/s of operational hashrate, roughly 7 percent of the global network’s computing power.

The company also closed on a second Texas campus, adding 300 megawatts of ERCOT approved capacity and bringing its total contracted power portfolio to 1.8 gigawatts.

Riskified anuncia la expansión de la inteligencia de agentes de IA para proteger a los asistentes de compras de IA nativos de los comerciantes

0


En el marco de una creciente adopción de agentes de IA nativos y chatbots en sitios web de tiendas minoristas, Riskified aprovecha su exclusiva infraestructura de datos para ayudar a que los comerciantes implementen asistentes de compras de IA seguros y altamente personalizados

Riskified (NYSE: RSKD), líder en inteligencia de riesgo y fraude para comercio electrónico, anunció hoy la expansión de su plataforma de inteligencia de agentes de IA, una iniciativa que posiciona a la empresa como la protección definitiva para la próxima era del comercio electrónico. A medida que los comerciantes explican sus propios asistentes de compras de IA conversacionales nativos para elevar la experiencia de cliente, Riskified garantiza que estos nuevos puntos de contacto estén protegidos contra sofisticadas formas de fraude y abuso.

Los minoristas están realizando grandes inversiones para llevar a los agentes de IA directamente a sus fachadas digitales. Una investigación de McKinsey & Company destaca esta tendencia y señala que el 82 por ciento de las organizaciones minoristas ya han lanzado pilotos de IA generativa dedicados a reinventar el servicio al cliente.

En un contexto donde los comerciantes diseñan sus asistentes de compras de IA para ofrecer una personalización profunda y sus programas de lealtad en función de las preferencias de los clientes, Riskified ofrece una capa de inteligencia de riesgo crítica que convierte a estas interacciones en inteligentes y seguras. Debido a que Riskified analiza el historial de compra completo del cliente final en una extensa red global de marcas de comercio electrónico, ofrece datos altamente diferenciados que los comerciantes no pueden desentrañar por su cuenta.

“Los comerciantes que buscan lanzar sus propios asistentes de compra virtuales tienen una ventaja crucial al mantener relaciones personalizadas y directas con sus compradores”, señaló Assaf Feldman, director de tecnología y cofundador de Riskified. “La función de Riskified es ser la capa de inteligencia de riesgo definitiva para mejorar y proteger las interacciones de los agentes de IA. Al potenciar el historial de los clientes propios del comerciante con perspectivas de nuestra vasta red compuesta por múltiples comerciantes, ayudamos a garantizar que cada transacción y reclamo realizado a través de un agente de IA del comerciante tenga detrás una identidad verificada”.

El objetivo de Riskified es proteger estos nuevos puntos de contacto contra formas sofisticadas de fraude y abuso mediante la introducción de distintas funcionalidades diseñadas específicamente para los asistentes de compras de IA conversacionales de los comerciantes:

  1. Señales de identidad de agentes de IA: permiten que un agente de compras de IA del comerciante realice consultas directas a Identity Graph de Riskified para recuperar indicadores de riesgo adicionales y resolver una identidad de forma programática. Esto puede hacerse a través de mejoras a AI Agent Approve, nuestra integración de MCP en AWS Marketplace, a través del protocolo de agente a agente (A2A) de Google, o a través de API REST estándar. En este modelo, Riskified actúa como “agente de confianza” y presta servicios de inteligencia de riesgo en tiempo real directamente en distintos momentos de la experiencia de compra donde puede agregar más valor. Por ejemplo, los agentes de IA nativos pueden obtener señales de riesgo en tiempo real mientras conversan con el cliente y ofrecer decisiones de reembolsos o cambios de producto instantáneas basadas en el riesgo y la elegibilidad del cliente.
  2. Mejoras al diseñador de políticas de agentes de IA: dentro de Riskified Decision Studio, los comerciantes pueden identificar y aplicar reglas comerciales para gestionar el riesgo del volumen de pedidos que proviene de sus agentes de compras de IA. Este control permitirá que los comerciantes implementen con confianza los agentes conversacionales de IA de marca propia sin exponerse a abusos de reclamos de reembolsos programáticos, arbitraje de revendedores o abuso de promociones.

El enfoque pragmático y específico de Riskified aborda la realidad de que las redes de fraude ya están explotando los protocolos agénticos y los chatbots de forma temprana. Al concentrarse en la resolución de identidad y las anomalías en patrones de compra, Riskified garantiza que la transición hacia compras mediadas por IA en los sitios web de los comerciantes siga siendo un factor para impulsar los ingresos, no un riesgo.

U.S. Contractor Arrested In $46M Theft Of Government Crypto

0

John Daghita, an alleged U.S. government contractor accused of stealing more than $46 million in cryptocurrency from the U.S. Marshals Service (USMS), was arrested last night on the island of Saint Martin in a coordinated operation between the FBI and French authorities. 

The arrest, confirmed via tweet by FBI Director Kash Patel, involved the French Gendarmerie’s elite tactical unit and the International Cooperation Team Serious Crime Unit.

“Thanks to the International Cooperation Team Serious Crime Unit of the French Gendarmerie National in Saint Martin, and the Groupe d’intervention de la Gendarmerie nationale of Guadeloupe for the outstanding coordination,” Patel wrote. “The FBI will continue working 24/7 with our international partners to track down, apprehend, and bring to justice those who attempt to defraud American taxpayers—no matter where they try to hide.”

The case centers on allegations that Daghita, identified online by blockchain investigator ZachXBT as “Lick,” exploited insider access to siphon digital assets from government-linked wallets. 

Daghita is the son of Dean Daghita, president and CEO of Command Services & Support (CMDSS), a Virginia-based technology firm contracted by the USMS to manage and dispose of certain categories of seized cryptocurrency.

CMDSS was awarded the contract in October 2024 to handle digital assets not supported by major exchanges, including funds tied to complex criminal cases and high-profile seizures, such as the 2016 Bitfinex hack. 

Daghita had access to millions in crypto

According to ZachXBT, Daghita demonstrated the ability to move millions of dollars in real time during a dispute recorded in a private Telegram chat. Subsequent on-chain analysis linked those wallets to addresses known to hold government-seized assets.

ZachXBT reported that one wallet allegedly controlled by Daghita held 12,540 ether, valued at roughly $36 million at current prices. 

Other transaction trails suggest approximately $20 million was removed from USMS-linked wallets in October 2024, most of which was returned within a day, though roughly $700,000 routed through instant exchanges was not recovered. 

Estimates of total suspected thefts may exceed $90 million when accounting for activity observed in late 2025.

U.S. officials have not publicly detailed how Daghita allegedly accessed the crypto or the wallets, nor whether CMDSS’s internal controls were bypassed or exploited. 

The case follows heightened scrutiny of the U.S. Marshals Service’s cryptocurrency holdings, which some analysts estimate at over 198,000 BTC, worth tens of billions of dollars. 

Allegations of insider theft and improper management have intensified calls for reform in how federal agencies secure and track digital assets, especially those seized from criminal cases.

US Bitcoin Reserve Has No Purchase Plans

0

One year ago, US President Donald Trump signed an executive order establishing a strategic crypto stockpile. Now, one year later, its value has decreased by billions.

At the beginning of his administration, Trump formed a working group to study how the government could best implement and regulate crypto. This included the Bitcoin (BTC) and crypto reserves.

Much has happened since. The first year of the Trump administration brought a number of macroeconomic and policy changes. Some of these, like new, friendly regulations from Washington, have been good for crypto. Others, like punitive tariffs and geopolitical escalation, have not.

Now the US’ crypto stockpile sits, with its token reserves largely unchanged since its establishment.

Little change in Trump’s crypto stockpile

On March 6, Trump formed the Strategic Bitcoin Reserve and U.S. Digital Asset Stockpile by executive order.

The Bitcoin reserve would comprise solely that asset, while the crypto stockpile would be a diverse collection of altcoins. Ahead of the executive order, Trump said that it would include XRP (XRP), Solana (SOL) and Cardano (ADA).

Both would “not acquire additional assets for the U.S. Digital Asset Stockpile beyond those obtained through forfeiture proceedings.”

The order effectively consolidated the forfeited assets, which at the time were spread across many different federal regulatory and law enforcement agencies. According to the order, it would also create an opportunity for the government to capitalize on the seized crypto.

“Taking affirmative steps to centralize ownership, control, and management of these assets within the Federal government will ensure proper oversight, accurate tracking, and a cohesive approach to managing the government’s cryptocurrency holdings,” the order stated.

The government does not publish the exact details of either the Bitcoin reserve or the crypto asset stockpile, but blockchain analysis firm Arkham Research has identified several blockchain wallets associated with the US government.

At publishing time, government crypto holdings are valued at $22,393,867,000, some $22 billion of which alone is Bitcoin. Other major holdings are stablecoin USDC (USDC), Ether (ETH), Wrapped Bitcoin (WBTC) and BNB (BNB).

Data collected on March 4.

How much these assets constitute the formal stockpile itself, or how and whether they were moved, is still not public information. But the dollar value has fallen significantly. According to Arkham, the US’ cumulative holdings were worth over $30 billion when Trump signed the order. At publishing time, they are worth $22 billion, a 26% decrease.

The White House appears unshaken by this. Deputy Press Secretary Kush Desai said regarding the recent price slump, “Volatility in a free market in which the government does not set prices is not going to change the Trump administration’s commitment to ensuring American dominance in cryptocurrency and other cutting-edge technologies of the future.”

Bitcoin token balance unchanged with no plans to buy

Despite hopes from Bitcoin maximalists that the US would start buying Bitcoin, the balance remains unchanged. Since the executive order, the US government has held 328,272 BTC.

The token balance of Ether, the next top asset by holdings in the US government’s portfolio, dropped off following the executive order, suggesting either an exchange or transfer. But after April 2025, the token balance stayed much the same.

Tether’s USDt (USDT), the largest stablecoin by token balance in the US’ portfolio, saw a significant jump in May 2025 of over 200 million tokens, before decreasing to pre-March 2026 levels.

These buying and selling patterns are not particularly clear. As noted above, the government makes no public disclosures about volumes.

While the new crypto reserve strategy did not completely preclude the government from buying Bitcoin, it required any purchases to be done in a budget-neutral fashion. AI and crypto czar David Sacks said last year, “It cannot add to the deficit, it cannot add to the debt, it cannot tax the American people.”

“It won’t cost the taxpayer dimes, but if the secretaries can figure out how to accumulate more bitcoin without costing taxpayers anything, then they are authorized to do that.”

One year on, it isn’t clear how or whether the administration has developed such a strategy.

Jason Yanowitz, co-founder of crypto firm Blockworks, told the BBC last year that a crypto stockpile made of several different assets could negatively impact markets. “Without a clear framework, we risk arbitrary asset selections, which would distort the markets and drive a loss of public trust.”

“Ensuring transparency through independent audits and public reporting is crucial for fostering innovation instead of favouritism,” he said.

The idea of Bitcoin reserves, be they at the state or corporate level, grew last year following the success of software company-cum-Bitcoin investment vehicle Strategy. The narrative of Bitcoin as digital gold made holding the asset an attractive prospect for government budgets.

According to data from tracking site BitcoinTreasuries.net, 10 countries hold Bitcoin, including the US, China, Ukraine, El Salvador, the United Kingdom and North Korea.

At the corporate level, analysts are expecting consolidation as the bear market continues. Wojciech Kaszycki, chief strategy officer of crypto infrastructure and treasury company BTCS, previously told Cointelegraph that companies with Bitcoin treasuries below net asset value will be acquired by operating businesses.

Bitcoin reserves are still a new idea that has yet to be tested in the depths of crypto winter.
