By 2027, stablecoins will process more remittances in Latin America than Western Union. That projection isn't speculation—it's the inevitable outcome of a market shift already in motion. On March 3, 2026, Sequoia Capital and Founders Fund validated this thesis with a $70 million bet on ARQ, the stablecoin-first financial platform formerly known as DolarApp.

ARQ's raise arrives at a pivotal moment for Latin American finance. The region recorded $324 billion in stablecoin transaction volume in 2025—an 89% year-over-year surge—while countries like Argentina and Venezuela now see stablecoin adoption rates exceeding 40% of the adult population. This isn't crypto experimentation. It's financial infrastructure rebuilding from the ground up.

The $161 Billion Remittance Opportunity​

Latin America and the Caribbean received $161 billion in remittances in 2025, a 5% increase from the previous year.

This massive inflow represents lifeline income for millions of families, but traditional money transfer services capture 6-8% in fees and delays. Western Union, MoneyGram, and banks have dominated cross-border flows for decades with infrastructure that treats Latin America as an afterthought.

Stablecoins are dismantling that monopoly. Sending USDT or USDC between the United States and Mexico now costs up to 50% less than traditional channels while settling in minutes instead of days. The math is compelling: on a $161 billion annual market, every percentage point of fee reduction represents $1.6 billion in saved value.

Brazil leads the transformation with $318.8 billion in crypto value received—nearly one-third of all Latin American crypto activity. Over 90% of Brazilian crypto flows are now stablecoin-related, underscoring their role as payment rails rather than speculative assets. The country's stablecoin law, taking effect this month (March 2026), provides regulatory clarity that institutional players have been waiting for.

From DolarApp to ARQ: The Strategic Pivot​

DolarApp launched three years ago with a focused proposition: help affluent Latin Americans access dollar-denominated financial services. The platform enabled users to open dollar accounts, transfer funds across borders, and protect savings from local currency devaluation. It was a digital version of the "mattress dollar"—the age-old strategy of holding US currency as a hedge against inflation.

The March 2026 rebrand to ARQ signals a strategic expansion beyond that niche. CEO Fernando Terrés explained the shift: "Before focused exclusively on solutions for international finances, ARQ now operates as a complete financial platform for daily use, integrating investments, consumption, and credit cards in a single ecosystem."

The company now serves 2 million+ customers and has crossed $10 billion in annualized transaction volume. That scale provides the foundation for a more ambitious vision: replacing traditional banks as the primary financial relationship for Latin America's digital-native consumers.

ARQ's new service portfolio includes:

  • Multi-currency accounts: Users hold digital dollars, digital euros, and local currencies with instant conversion at real market rates without hidden fees
  • International payments: Direct transfers from the US and Europe at real conversion rates, targeting remote workers, freelancers, and expats
  • Wealth management: Access to leading stocks and ETFs with zero trading fees, bringing Wall Street to users previously locked out of US markets
  • High-yield accounts: Up to 4.5% annual earnings on deposits—substantially higher than local bank offerings in high-inflation economies
  • Credit services: The Prestige credit card provides international purchasing power without forex markups

The platform supports deposits via CLABE (Mexico), CVU/Alias (Argentina), PSE (Colombia), and Pix (Brazil), integrating seamlessly with local payment infrastructure while offering stablecoin-powered cross-border rails.

Why Stablecoins Won Latin America​

Latin America's embrace of stablecoins isn't ideological—it's pragmatic survival in economies where currency devaluation can erase 50% of savings value in a year. Argentina's peso lost 90% of its value against the dollar between 2018 and 2023. Venezuela's bolivar experienced hyperinflation that made currency essentially worthless.

In this context, stablecoins like USDT and USDC aren't "crypto"—they're digital dollars.

The adoption statistics are staggering:

  • 75% of Latin American institutional investors now allocate to stablecoins
  • USDT dominates with 68% market share across the region
  • Stablecoin transaction volumes grew 89% year-over-year to reach $324 billion in 2025

USDT emerged as the clear leader in high-inflation economies like Argentina and Venezuela, where users prioritize liquidity and exchange availability over regulatory compliance nuances. Meanwhile, USDC has gained traction in Mexico and Brazil thanks to strategic partnerships with fintech platforms like ARQ that emphasize regulatory compliance and institutional-grade infrastructure.

The remittance use case demonstrates stablecoins' practical superiority. Traditional services charge 6-8% in fees and take 3-5 days for settlement. Stablecoin transfers cost 1-2% (or less with direct peer-to-peer transactions) and settle in minutes. For a worker sending $500 monthly from the US to family in Colombia, that's $300-420 in annual savings—enough to pay for a month of groceries.

ARQ's Competitive Edge: Infrastructure Meets Compliance​

ARQ competes in a crowded fintech landscape that includes regional players like Bitso, Ripio, and international giants like Binance and Coinbase. Its differentiation comes from combining stablecoin infrastructure with regulated financial services.

The platform operates in four countries—Mexico, Brazil, Argentina, and Colombia—each with distinct regulatory frameworks. Brazil's new stablecoin law provides the clearest path for compliant operations. Mexico's Fintech Law (enacted 2018) created a regulatory sandbox that ARQ has leveraged. Argentina's regulatory approach remains fragmented but pragmatic given the peso's instability. Colombia has taken a cautious stance, but remittance flows create permissive conditions for stablecoin adoption.

Kaszek Ventures, a prominent Latin American VC firm, participated in ARQ's previous funding rounds alongside Y Combinator. Kaszek's portfolio strategy reveals the infrastructure thesis: in January 2026, the firm co-led a $55 million Series C for Pomelo, a payments infrastructure company building stablecoin-native global cards and payment tokenization.

This points to a broader trend: Latin American fintech is leapfrogging traditional card networks and correspondent banking infrastructure by building on stablecoin rails from the ground up. ARQ benefits from timing—it's scaling as this infrastructure matures, rather than betting on unproven technology.

The company's $70 million raise will fund "new hires and expansion beyond dollar-denominated transfers," according to Terrés. This likely means:

  1. Credit infrastructure: Launching lending products backed by stablecoin collateral
  2. Geographic expansion: Entering Peru, Chile, and other Andean countries
  3. B2B services: Offering treasury management and payment infrastructure to businesses
  4. Institutional products: High-net-worth wealth management and corporate foreign exchange services

The Infrastructure Race: USDT vs USDC and Regulatory Convergence​

Two stablecoins dominate Latin America's market—Tether's USDT with 68% market share and Circle's USDC gaining institutional traction. Their competition reflects different strategies for emerging market adoption.

USDT built dominance through liquidity and exchange availability. Users in Argentina or Venezuela can find local buyers and sellers for USDT on peer-to-peer platforms within minutes.

This network effect creates self-reinforcing adoption: more users attract more liquidity, which attracts more users. Tether's approach prioritized accessibility over regulatory compliance, enabling rapid growth in markets where formal banking infrastructure is weak or unreliable.

USDC took a different path: partnering with regulated fintech platforms and emphasizing full reserve auditing and compliance frameworks. Circle's strategy aligns with institutional adoption and regulatory convergence. As Latin American governments implement stablecoin regulations—like Brazil's March 2026 law—USDC's compliance infrastructure becomes an advantage rather than overhead.

ARQ's business model depends on both. The platform must support USDT for users demanding maximum liquidity and USDC for customers prioritizing regulatory compliance and institutional credibility. This dual-stablecoin strategy mirrors the broader market: retail users favor USDT, while businesses and high-net-worth individuals increasingly prefer USDC.

The regulatory landscape is converging toward legitimacy. Brazil's stablecoin law mandates full reserves, licensed issuers, and consumer protections—mirroring frameworks in the US (GENIUS Act timeline) and EU (MiCA regulations). This convergence creates opportunities for platforms like ARQ that positioned themselves as compliant infrastructure from the start.

What ARQ's Success Means for Global Fintech​

Latin America has become the proving ground for stablecoin-native financial services. If ARQ can build a $10 billion+ transaction volume business serving 2 million users with stablecoin infrastructure, that model becomes exportable to other emerging markets facing similar currency instability and remittance flows.

Southeast Asia, Sub-Saharan Africa, and Eastern Europe all share Latin America's characteristics: large diaspora populations sending remittances, currency instability, high mobile penetration, and distrust of traditional banks. The total addressable market for stablecoin-first banking extends well beyond Latin America's $161 billion annual remittance flows.

Sequoia and Founders Fund's $70 million bet on ARQ isn't just about Latin America—it's about staking a position in the infrastructure layer of global finance's next phase. If stablecoins become the dominant rails for cross-border payments and savings in emerging markets, the platforms facilitating access capture enormous value.

ARQ's rebranding from "DolarApp" to a broader identity reflects this ambition. The name change removes the dollar-centric limitation, enabling the company to expand into euro-denominated services, local currency products, and eventually cryptocurrency-adjacent offerings like tokenized securities or DeFi access.

The company's growth trajectory—from launch to $10 billion annualized volume in three years—suggests product-market fit at a profound level. Latin Americans aren't using ARQ because they love crypto or believe in decentralization. They're using it because it solves real problems: preserving purchasing power, accessing global financial markets, and sending money across borders cheaply and quickly.

The Path Forward: Consolidation or Fragmentation?​

The Latin American fintech landscape faces a strategic question: will stablecoin-based services consolidate into a few regional champions, or will fragmentation persist across national markets?

ARQ's four-country footprint (Mexico, Brazil, Argentina, Colombia) positions it for regional dominance, but meaningful challenges remain. Each country has distinct regulatory frameworks, local payment systems, and competitive dynamics. Brazil's scale (211 million population, $318.8 billion in crypto flows) makes it an obvious priority, but Argentina's crisis-driven adoption (40%+ adult population using stablecoins) offers explosive growth potential.

Competitors aren't standing still. Bitso, a Mexican crypto exchange, has expanded across Latin America with regulatory licenses and local partnerships. Ripio operates in Argentina, Brazil, Mexico, and Uruguay with a similar crypto-to-fiat strategy. International players like Binance and Coinbase offer stablecoin services with global scale and brand recognition.

ARQ's differentiator is its fintech-first positioning. Unlike crypto exchanges that added banking features, ARQ started as a banking app that uses crypto infrastructure. This matters for user acquisition: consumers don't want "crypto," they want better banking. ARQ's interface, messaging, and product design emphasize financial services over blockchain technology.

The $70 million from Sequoia and Founders Fund provides runway for aggressive expansion, but execution challenges loom:

  1. Regulatory compliance: Navigating four (soon more) national frameworks with different licensing requirements, consumer protection rules, and capital requirements
  2. Customer acquisition cost: Competing with established banks and crypto exchanges for digital-native users in competitive markets
  3. Credit risk: Launching lending products backed by volatile crypto collateral requires sophisticated risk management
  4. Technology infrastructure: Supporting multi-currency accounts, real-time foreign exchange, international payments, and wealth management at scale

Conclusion: Latin America as the Stablecoin Laboratory​

ARQ's $70 million raise validates a thesis that seemed radical just three years ago: stablecoins can become the foundational infrastructure for consumer finance in emerging markets. The company's growth from launch to $10 billion in annualized transaction volume, serving 2 million customers across four countries, proves that product-market fit exists at scale.

Latin America's unique combination of currency instability, massive remittance flows, high mobile penetration, and regulatory pragmatism makes it the ideal laboratory for stablecoin-native banking. The region's $324 billion in stablecoin transaction volume (2025) and 89% year-over-year growth demonstrate that this isn't a niche market—it's a fundamental shift in how money moves across borders and preserves value.

The projection that stablecoins will process more remittances than Western Union in Latin America by 2027 now seems conservative. With 75% of institutional investors allocating to stablecoins and countries like Argentina seeing 40%+ adult adoption, the infrastructure transition is accelerating faster than traditional players can respond.

ARQ's rebrand from DolarApp to a broader financial super app signals the next phase: moving beyond remittances and savings into credit, wealth management, and B2B services. If the company executes this expansion successfully, it won't just disrupt traditional remittance providers—it will challenge commercial banks as the primary financial relationship for Latin America's 650 million people.

For blockchain infrastructure providers, the ARQ story underscores a crucial insight: the most valuable applications of stablecoins aren't DeFi protocols or speculative trading—they're prosaic financial services that solve urgent problems for people living with currency instability. Latin America's embrace of stablecoins proves that when the alternative is watching your savings evaporate to inflation, "crypto" stops being crypto and becomes essential infrastructure.

Stablecoin-based financial infrastructure requires reliable blockchain APIs that can handle high transaction volumes across multiple chains and geographies. BlockEden.xyz provides enterprise-grade API access for Ethereum, Polygon, and other networks supporting stablecoin operations at scale.
