Ripple, the leading blockchain technology company that provides blockchain-based solutions to banks and financial institutions, has just invested in Flutterwave, Africa’s biggest fintech unicorn.

 

The investment, which was part of Flutterwave’s Series E funding round, aligns with the unicorn’s long-term value proposition to build Africa’s leading unified payments infrastructure that connects the continent seamlessly to the global economy.

 

 

According to Flutterwave, the partnership is built on three core pillars: embedding Ripple’s RLUSD into Flutterwave’s payment rails to scale large volume payments and remittances; leveraging Ripple’s XRP Ledger for faster transaction clearing; and deploying a unified API that seamlessly bridges Flutterwave’s domestic network with Ripple’s global payment network.

 

"This investment marks a pivotal moment in our journey, enabling us to significantly scale our infrastructure and expand our stablecoin-enabled payments roadmap,” said Olugbenga "GB" Agboola, Flutterwave’s Founder and CEO.

 

“By unlocking faster settlement and lower cost cross-border payments, we are building a payment superhighway that connects African commerce directly to the global economy. This partnership is a catalyst for Nigerian and African sovereignty in the digital financial age, ensuring our markets are primary participants in the global digital asset revolution.”

 

Through partnering with Ripple, Flutterwave takes a significant step towards achieving its “stablecoin first” payment infrastructure that eliminates traditional bottlenecks. By integrating Ripple’s RLUSD stablecoin into its payment infrastructure, Flutterwave aims to deliver immense speed, liquidity, and cost efficiency to Africa’s cross-border payment network, transforming how Africa interacts with global markets.

 

About Flutterwave 

Flutterwave is one of Africa’s leading fintech companies. Launched in 2016, Flutterwave was created to solve fragmented payment systems that limited Africa’s connection to the global economy. Through a single API and platform, Flutterwave enables businesses to accept payments, make payouts, and process cross-border transactions across Africa and internationally.

 

Since its inception, Flutterwave has raised over $ 500 million through multiple funding rounds and is currently valued at $ 3.2 billion, making it Africa’s most highly valued fintech company. Its services are available in more than 35 African countries, and its payment infrastructure supports over 150 currencies.

 

 

Stablecoin issuer Tether has announced its role as the lead investor in Neura Robotics’ recent Series C funding round. The funding round, which raised an estimated $1.4 billion, included Qualcomm, Amazon, and NVIDIA among other investors.

 

 

By investing in Neura Robotics, Tether is extending its influence beyond the digital asset industry, enabling it to deploy some of its core technologies into the humanoid robotics ecosystem. The partnership also enables the integration of Tether’s Wallet Development Kit and Tether’s self-custody wallets into the Neura Robotics system.

 

Through this integration, Tether provides a foundation that enables Neura Robotics to develop robotic systems that earn micropayments for tasks, transact with other robotic systems, and autonomously facilitate transactions and receive payments between machines without human intervention.

 

As part of its partnership, Neura Robotics will collaborate on testing, improving, and deploying Tether’s QuantumVerse Automatic Computer, known as QVAC, into its Neuraverse ecosystem. QVAC is Tether’s open-source, decentralized artificial intelligence platform that enables users to run and fine-tune large language models directly on their devices without relying on cloud servers.

 

“As robotics moves beyond scripted automation and into true autonomy, the infrastructure behind it must evolve as well,” said Paolo Ardoino, chief executive officer of Tether.

 

“Autonomous machines need the ability to process information locally, make decisions, and transact without relying on centralized intermediaries. QVAC brings that edge-first intelligence to the platform while WDK handles the secure financial layer. Together, they enable machines to execute tasks, account for outcomes, and operate independently. NEURA Robotics shares that vision, and this investment reflects our confidence in what autonomous robotics can become.”

Japan’s top three largest banks, Mitsubishi UFJ Financial Group (MUFG), Sumitomo Mitsui Banking Corporation, and Mizuho Bank, Ltd, have announced plans to jointly launch a yen-backed stablecoin by March 2027.

 

In a recent press release, the three megabanks said plans were already in place for the trio to conduct actual commercial transactions using the stablecoin. This is not a test or pilot program but a real financial infrastructure enabling stablecoin-based payments.

 

As a major step toward this goal, the three megabanks signed a Memorandum of Understanding (MoU) to establish a voluntary joint council responsible for developing the stablecoin operational framework, including issuance infrastructure, systems, schemes, governance, and future collaboration with other institutions.

 

Together with the Financial Services Agency (FSA), Japan’s primary financial regulatory authority, the three banks conducted a FinTech Proof of Concept pilot program around November 2025. The goal of the pilot was to assess whether multiple banks could jointly issue the stablecoin while ensuring compliance with all regulatory, legal, and compliance standards.

 

The Mitsubishi UFJ Financial Group’s partnership with the two other megabanks comes shortly after Mitsubishi Corporation, an entity within the broader Mitsubishi Group, adopted JPMorgan’s Kinexys blockchain network for cash management for its global subsidiaries.

 

Just like Japan’s megabanks' collaboration to launch a stablecoin, other banks have made similar moves, notable among which is Qivalis, a consortium comprising 37 European banks that are collaborating to launch a stablecoin for the euro.

 

Stablecoins continue to grow rapidly, with many traditional financial institutions entering the sector. According to a recent report, stablecoin transaction volume exceeded 28 trillion dollars in the first quarter of this year, approaching the 33 trillion dollar annual transaction volume recorded in 2025. US dollar pegged stablecoins still make up a large share of the global stablecoin supply, representing about 97 percent of the total global stablecoin supply.

 

 

Zodia Custody, a company that provides institutional custody for cryptocurrencies and digital assets, has secured a payment license from Luxembourg’s Commission de Surveillance du Secteur Financier (CSSF), the country’s primary financial regulator.

 

 

With this payment license secured, Zodia Custody is set to expand beyond crypto custody, its main offering, and is now moving into both the custody and seamless transfer of electronic money tokens and stablecoins within the European Union.

 

“Institutional adoption of crypto assets demands infrastructure that meets the highest standards of regulatory adherence and operational efficiency,” said Ami Nagata, Managing Director, Luxembourg at Zodia Custody Europe.

 

“Securing a Payment Institution license alongside our MiCA CASP authorization is a critical step in bridging our capabilities across crypto asset safekeeping. With both licenses in place, our clients have the certainty they need to manage their electronic money token and crypto asset strategies across Europe, with full confidence that their assets are safeguarded within a bank-grade environment.”

 

Alongside the payment license and the MiCA license it secured in December last year, Zodia Custody is now well-positioned to serve as a core infrastructure provider for institutional digital finance. Securing these licenses removes structural barriers and counterparty risks commonly associated with crypto asset service providers.

 

The securing of the Luxembourg payment license comes shortly after Standard Chartered made a non-binding offer to acquire Zodia Custody. Although the acquisition cost was not publicly disclosed, the offer has already been accepted by Zodia Custody shareholders.

 

Zodia Custody currently serves a number of institutional clients, including 21Shares, Re7 Capital, Bitwise, and BitMEX. In April of this year, Zodia Custody partnered with BitMEX to integrate the Interchange platform into BitMEX's infrastructure to enable off-exchange trading, a move that enhances the safety of clients' assets on the BitMEX platform, especially in the event of a security breach.

 

 

Mastercard is expanding its stablecoin settlement capabilities to support intraday, weekend, and holiday settlements using both fiat currencies and on-chain card settlements.

 

 

According to Mastercard, the expansion is aimed at providing users across the company's global payments network with greater flexibility, allowing them to better manage liquidity and gain greater control over how their money moves. The expansion is also expected to facilitate transactions that depend on timing and transparency, including cross-border payments, treasury operations, and payouts.

 

"The next phase of stablecoin adoption is about real-world utility, especially in settlement, where timing and liquidity matter most," said Raj Dhamodharan, executive vice president of Blockchain & Digital Assets at Mastercard.

 

"By introducing intraday and weekend settlement options across our global network, we're expanding how partners manage liquidity and operate in an always-on digital economy while maintaining the trust, resilience, and safeguards they expect from Mastercard."

 

With this expansion, Mastercard will support additional stablecoins, including Paxos's PYUSD, USDG, and USDP; Ripple's RLUSD; and SoFi's SoFiUSD, in addition to Circle's USDC, which it already supports. These stablecoins will be supported across multiple blockchain networks, including Arbitrum, Base, Canton, Ethereum, Polygon, Solana, Tempo, and XRPL.

 

ARQ (formerly known as DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei will be among the first companies in the United States and Latin America to support Mastercard's stablecoin settlement options, with further expansion expected throughout the year.

 

Mastercard's addition of more settlement options comes shortly after the payments giant acquired BVNK, a leading stablecoin infrastructure company, in March. The acquisition is part of Mastercard's broader strategy to connect on-chain payment rails with traditional fiat rails.

 

Mastercard is currently one of the world's largest payment processing networks, with more than 150 million merchant locations across 210 countries and territories. The company processed approximately $10.6 trillion in gross dollar volume (GDV) and reported net revenue of about $8.4 billion in the first quarter of this year.

 

 

Decentralized finance protocol Ethena Labs has partnered with Anchorage Digital, a digital asset infrastructure provider, to expand its presence in institutional lending through Anchorage Digital's Atlas Collateral Management platform, which manages institutional-grade digital asset collateral.

 

 

As Ethena Labs seeks to deepen its involvement in institutional lending, the partnership will see Anchorage Digital act as collateral manager for Ethena's institutional lending activities. This arrangement allows Ethena to focus on deploying capital for loans, while Anchorage Digital manages and safeguards the associated collateral under its custody.

 

"Institutions want access to crypto native capital, but not at the cost of custody, controls, or operational rigor. Atlas Collateral Management lets protocols like Ethena Labs meet institutional borrowers where they are, combining the speed of DeFi with the standards institutions require," said Nathan McCauley, Co-Founder and CEO of Anchorage Digital.

 

Through the Atlas Collateral Management platform, Anchorage can monitor collateral and loan thresholds in real time, support margin processes, and execute rules-based actions when necessary. Because the collateral remains under Anchorage's custody and does not move on the chain, Ethena can access traditional institutional lending markets without requiring institutions to adopt blockchain native custody solutions or interact directly with DeFi smart contracts.

 

For borrowers, the collaboration provides access to crypto native credit while allowing them to maintain their existing custodial, compliance, and risk management frameworks. Atlas offers protocols a streamlined way to expand into institutional lending without building and maintaining their own collateral management, monitoring, and liquidation infrastructure.

 

The partnership between Ethena Labs and Anchorage Digital builds on an existing relationship. In July 2025, Ethena partnered with Anchorage Digital Bank, the first federally chartered crypto bank in the United States, to become the primary issuer of USDtb, Ethena Labs' institutional-grade stablecoin.

 

As part of its broader push into institutional lending, Ethena recently partnered with Solana-based DeFi platform Jupiter and Bitwise Asset Management to launch an institutional-grade USDe lending market on Jupiter's lending platform.

 

The partnership between Anchorage Digital and Ethena Labs comes at roughly the same time as Coinbase's investment in Ethena Labs, which included the purchase of an undisclosed amount of ENA tokens. Coinbase and Ethena are working together to launch on-chain savings and finance products for Coinbase's more than 100 million users.

 

 

MoneyGram has launched MGUSD, a U.S. dollar pegged stablecoin on the Stellar blockchain network, aimed at facilitating cross border transfers and remittances.

 

According to MoneyGram, the MGUSD stablecoin is designed to serve non crypto native users, particularly people who regularly move money across borders and those with little or no access to local financial services, including individuals living in high inflation markets.

 

 

By launching MGUSD, MoneyGram aims to provide these users with greater financial stability, enabling them to hold and access their dollar denominated MGUSD assets around the clock and convert MGUSD into local currencies whenever they choose, from anywhere in the world and on their own terms.

 

"The stablecoin market has largely focused on the asset itself. MoneyGram is taking a fundamentally different approach. Starting with our distribution platform, we're using stablecoin as a foundation to build future applications on our global network," said Anthony Soohoo, Chairman and Chief Executive Officer of MoneyGram.

 

"MGUSD is the stablecoin we built for our customers, for the families sending money home and for the billions of people around the world with limited financial access."

 

The launch of MGUSD was made possible through partnerships with several companies involved in the project. These include Stellar, which provides the blockchain on which MGUSD is issued; Bridge, a Stripe owned company that serves as the regulated issuer of the stablecoin; M0, which provides the smart contract infrastructure for minting and burning the stablecoin; and Fireblocks, which provides custodial services.

 

MGUSD will be integrated directly into the MoneyGram app through a self custodial wallet that will allow users to view their dollar denominated balances. Although MGUSD has launched in the U.S. market, MoneyGram said it plans to expand the stablecoin's availability globally.

 

About MoneyGram 

MoneyGram is a global financial services company that provides fast, accessible cross border money transfers, particularly for people with limited access to traditional banking services. Its core mission is to make sending money across borders simple, reliable, and accessible to millions of migrant workers and their families.

 

In line with this mission, MoneyGram operates one of the world's largest networks, with nearly 500,000 agent locations worldwide and more than 5 billion endpoints. The company serves more than 60 million active users across 200 countries and territories.

 

 

Block's Cash App has officially begun rolling out USDC stablecoin payments to its nearly 60 million monthly users. The feature went live today for roughly 25% of the platform's user base, with full availability expected by the end of the week.

 

The rollout covers four blockchain networks: Solana, Ethereum, Polygon, and Arbitrum. Users can now send USDC from their Cash App wallet to external wallets on any of the supported chains, and incoming USDC is automatically converted into a dollar balance within the app. No separate transfer fee applies, at least for now.

 

A Reluctant Pivot, Years in the Making

The launch carries some ideological weight. Jack Dorsey, Block's CEO and longtime Bitcoin maximalist, spent years positioning Cash App as a Bitcoin-first platform. He built out Bitcoin trading, backed mining hardware development, and integrated Lightning Network support for Square merchants globally. Stablecoins were not part of that vision.

 

That changed, grudgingly. In March, Dorsey publicly acknowledged the shift. "I don't like that we're going to support stablecoins but our customers want to use them," he said. "I don't think it's wise to go from one gatekeeper to another." The comment was candid in a way that's rare for major fintech announcements, and it framed the product addition less as strategic enthusiasm and more as a concession to market demand.

 

Block first hinted at the feature on the Cash App website late last year, describing stablecoins strictly as a payments mechanism rather than an investment tool. But that early hint has carried through to the live product.

 

Why Solana (and Why Not Just Solana)

Solana started as the sole chain involved with Cash App. Back in November 2025, Solana confirmed its involvement after sharing a demo by Circle's Jeremy Allaire showcasing a USDC transfer on the network. The choice made sense: Solana transactions typically cost under a cent and settle in under a second, conditions well-suited for the kind of peer-to-peer and remittance use cases Cash App serves.

 

But Block's Miles Suter framed the company's stance as "chain- and coin-agnostic" from the beginning. Solana was a starting point, not a commitment. The live rollout now includes Ethereum, Polygon, and Arbitrum alongside Solana, giving users flexibility across networks with different cost and speed profiles. Ethereum's gas fees can still spike during congestion, which is precisely why Layer 2 options like Arbitrum and Polygon matter.

 

The multi-chain approach also future-proofs the integration somewhat. If one network faces congestion or reliability issues at scale, users and the platform aren't locked in.

 

The Guardrails Are Real

Cash App is not positioning this as a DeFi on-ramp. The feature comes with meaningful restrictions. Sending is capped at $2,000 per day and $5,000 per week; receiving tops out at $10,000 weekly. The service is currently unavailable in New York and on sponsored accounts. Identity verification is required.

 

Perhaps most importantly, the app warns users that blockchain transactions are irreversible. Funds sent to a wrong address or unsupported network are gone permanently. That's a steep hill to climb for a consumer platform serving tens of millions of people who may be encountering on-chain transfers for the first time.

 

Stablecoins Are Here To Stay...and Thrive

Cash App's move lands against a backdrop of surging stablecoin adoption. As of this week, the total market value of stablecoins has hit a record $322 billion, exceeding the foreign exchange reserves of 95 nations, including the UK and Canada. USDC, issued by Circle, is the second-largest stablecoin and already sees over $14 billion in liquidity on Solana alone.

 

Western Union launched Solana-based remittances in the first half of 2026. Stripe has added USDC support across multiple chains. Visa has integrated Solana for stablecoin settlements. The regulatory picture has also clarified somewhat, with the GENIUS Act signed in July 2025 establishing a clearer federal framework for stablecoin issuance.

 

Taken together, this feels less like a novelty launch and more like a platform making its peace with where consumer payments are heading. Dorsey may not love it, but the product is live, the networks are there, and 60 million people now have a relatively frictionless path to on-chain dollar transfers whether they know what a blockchain is or not.

 

EURR and USDR, stablecoins issued by StablR, have each lost their euro and dollar pegs following an exploit on StablR’s multisignature wallets.

 

The exploit, first flagged by on-chain sleuth ZachXBT, led to losses of about $10 million. According to ZachXBT, two contracts tied to StablR were exploited, with the attacker funding their wallet through Circle’s Cross Chain Transfer Protocol (CCTP) on Noble.

 

In a further update on his Telegram channel, ZachXBT said he had helped freeze six figures worth of the stolen funds, while adding that the StablR team appeared to be inactive as the attack was still ongoing three hours after he raised the alarm.

 

Blockchain security company Blockaid also detected the exploit, attributing the compromise to a private key issue in StablR multisignature wallets. According to Blockaid, the attacker gained access to one of StablR’s three multisignature wallets.

 

Since the multisignature wallet had a threshold of 1 out of 3, the attacker, after gaining admin access, replaced the other two legitimate owners. The attacker then minted 8.35 million USDR and 4.5 million EURR stablecoins and swapped them on decentralized exchanges. Blockaid further stated that the attack was not a smart contract bug, but instead a key management and governance failure.

 

A few hours after the incident was flagged, the StablR team issued a security update stating that they were actively working to contain and minimize the impact of the hack.

 

 

At the time of writing, EURR, StablR’s euro-pegged stablecoin, had lost about 53 percent of its value, dropping to about $0.54 according to CoinGecko. USDR, the stablecoin pegged to the US dollar, had risen slightly to $0.99.

 

This is not the first time a protocol has lost its stablecoin peg due to a governance exploit. In March of this year, Resolv Lab suffered a governance exploit that enabled attackers to gain admin access and mint roughly $80 million worth of Resolv’s USR, a dollar-pegged stablecoin.

 

Due to this uncontrolled minting, the USR stablecoin lost its peg to the US dollar, crashing to roughly $0.05 within minutes. USR is currently trading at $0.16 according to CoinGecko.

 

 

Tether, the largest stablecoin issuer, has partnered with the Georgian government to launch GELT, a stablecoin representing the lari, the country’s official currency.

 

 

The partnership, announced on Monday, aims to create a financial ecosystem that supports cross-border commerce, fintech development, and broader access to programmable financial infrastructure across Georgia.

 

GELT will serve as a digital representation of the Georgian lari and will be designed to enable lower transaction costs, near instant settlement, programmable payments, and more efficient movement of value across digital financial systems.

 

“Together with visionary partners like Tether, Georgia is laying the foundations for a more connected, transparent, and digitally empowered financial world,” said Irakli Kobakhidze, Prime Minister of Georgia.

 

The launch of the GELT stablecoin is built on a regulatory framework created by the Georgian government and the National Bank of Georgia. In March this year, the National Bank of Georgia developed a framework governing the issuance of stablecoins.

 

The framework, officially known as “The Rule for the Initial Coin Offering of a Stable Virtual Asset by a Virtual Asset Service Provider,” sets out standards that must be met by all virtual asset service providers (VASPs) operating in the country, including requirements for 100 percent reserve backing, strong consumer protections, proper risk management, and full compliance with the country’s Anti Money Laundering (AML) standards.

 

“Stablecoins are no longer a niche financial instrument. They are becoming part of the infrastructure layer for global finance,” said Paolo Ardoino, CEO of Tether. “Georgia has moved early to create serious regulatory architecture for digital assets and stablecoins, and that clarity creates the foundation for real innovation and adoption.”

 

Georgia’s stablecoin framework is also designed to be compatible with other regulatory frameworks, including the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) and Markets in Crypto Assets (MiCA).

 

By partnering with Tether to launch the GELT stablecoin, Georgia becomes the first country to team up with a major stablecoin issuer to issue a government-supported stablecoin pegged to its national currency. The UAE has also launched a dirham-pegged stablecoin, but unlike Georgia’s GELT, that stablecoin was issued by local consortia rather than a major stablecoin issuer such as Tether.

 

The planned launch of the GELT stablecoin comes shortly after Tether launched its self-custodial wallet. In an effort to increase access to stablecoins, Qivalis recently expanded its consortium to include more banks, which are collectively working to launch a euro-pegged stablecoin.

 

Qivalis, an Amsterdam-based joint venture developing a fully regulated MiCA-compliant euro stablecoin, has expanded its consortium to include 25 new banks.

 

 

With this expansion, the Qivalis consortium now comprises 37 banks across 15 European countries, including major names such as ABN AMRO, Rabobank, Nordea, Intesa Sanpaolo, Banco Sabadell, and Bankinter.

 

Created in early December last year, the Qivalis consortium is a group of European banks that came together to develop a stablecoin pegged to the euro. By launching a euro-pegged stablecoin, Qivalis aimed to create a credible and regulated alternative to the widely used United States dollar stablecoin.

 

The Qivalis euro-backed stablecoin would also eliminate the need for European banks to launch competing bank-issued stablecoins, as it is interoperable and fully compliant with MiCA across the European Union and the European Economic Area.

 

The consortium is currently pursuing an Electronic Money Institution license from De Nederlandsche Bank, the Dutch central bank, with plans to launch a euro-backed stablecoin in the second half of this year.

 

The State of the Stablecoin Market

The stablecoin market continues to grow significantly, with more traditional finance institutions entering and tapping into the expanding sector. According to a recent report, total stablecoin liquidity, or market capitalization, has crossed $320 billion, with US dollar-backed stablecoins accounting for about 95% of the market.

 

Tether (USDT) remains the most widely used US dollar-backed stablecoin, accounting for about 57.96% of the market, or approximately $ 185 billion in market capitalization. USD Coin (USDC) follows, accounting for about 24% of the market and having a market capitalization of roughly $78-79 billion.

 

The euro-denominated stablecoin market still represents a small fraction of the global stablecoin market. According to CoinGecko, euro-denominated stablecoins have a combined market capitalization of roughly $670 million, with EURC from Circle and EURS from Stasis being the two most prominent, with market caps of $436 million and $145 million, respectively.

 

 

Flipcash, a digital payment app founded by Ted Livingston, the founder of messaging app Kik, has partnered with Coinbase to launch USDF, a stablecoin pegged to the U.S. dollar.

 

 

According to Coinbase, the launch aims to make stablecoin issuance more accessible. Through the partnership, Flipcash can leverage Coinbase’s custom stablecoin platform to create its own stablecoin asset without having to handle much of the underlying technical complexity itself. As a result, Flipcash does not need to build an entire stablecoin infrastructure from scratch.

 

The USDF stablecoin will be issued on the Solana blockchain and will be 1:1 backed by USDC. It will also serve as Flipcash’s native currency. Since Flipcash allows users to create their own digital currencies, USDF will be the asset in which those currencies are priced and settled. It will serve as the settlement asset for trading digital currencies within the Flipcash app.

 

Coinbase’s Custom Stablecoin Platform 

Coinbase custom stablecoin, or stablecoin as a service, is a platform launched by Coinbase in 2025 that allows businesses to easily create and issue their own branded stablecoins backed by the United States dollar.

 

As the stablecoin market continues to grow and gain institutional adoption, Coinbase launched its stablecoin platform to make it easier for businesses to enter the stablecoin market, reducing the technical and compliance work associated with issuing stablecoins.

 

Stablecoins launched on Coinbase’s custom stablecoin platform, including USDF, which is the first stablecoin created on the platform, will maintain a 1-to-1 backing with USDC and will be supported across multiple chains, including Base and Solana.

 

About Flipcash 

Flipcash is a Solana-based non-custodial mobile wallet and digital payment app created by Canadian entrepreneur Ted Livingston in 2021.

 

It was created to digitize cash and make peer-to-peer payments as frictionless as possible. Through its “Currency Creator” feature, which officially went live last month, Flipcash allows anyone to create a fixed supply of digital currencies.
