Commercial cross-border payments in emerging markets are now settling on stablecoin rails.
Most stablecoin pitches focus on disrupting U.S. cards. That could take decades to play out. This memo focuses on what is already happening: stablecoins are becoming the preferred method for cross-border commercial payments in emerging markets.
Wex operates in eleven countries today and Corporate Payments processes transactions in over 210. Earlier crypto categories delivered speculation. Stablecoins solve concrete payment problems for Wex's customers and reach markets existing solutions cannot.
What follows is the case for the space, an evaluation framework, and two specific early-stage companies worth a call.
For fifteen years, cryptocurrency adoption beyond speculation and investment has been negligible. Stablecoins are the exception. They are showing real product-market fit for cross-border payments, particularly in emerging markets. The chart below makes the point in a single image: across the largest crypto categories, only stablecoins have moved meaningful real-world payment volume.
Five observations make the case. The first three are happening now. The last two are about what is coming.
Stablecoins moved dollars faster than traditional rails partly because they operated in a regulatory gap. Whether they were money, securities, or payment instruments was deliberately unclear, which let them route around the slow parts of the dollar system. The GENIUS Act, signed July 2025, did not close that gap. It ratified it. Banks that could not touch stablecoins in 2023 are now building tokenized deposit products on the same rails.
The author's recent attempt to pay a contractor in Venezuela went nowhere on the traditional rails. The app that completed the payment was Kontigo, a company in the author's YC batch. The pattern repeats wherever local currency is unstable, correspondent banking is unreliable, or capital controls block currency conversion.
Starlink sells in 120+ countries. Bridge converts Nigerian Naira, Argentine pesos, Brazilian reais, and Turkish lira into USDC, then settles to dollars in SpaceX's U.S. treasury within hours. This allows Starlink to operate in markets where normally wires take a week, currency depreciation erodes the float in transit, and capital controls block direct conversion entirely.
The most striking single-year data point is that 2025 was the first year speculative crypto activity contracted while stablecoin payment volume expanded. The two trends are moving in opposite directions for the first time on record.
The countries that drive stablecoin volume today are where most of the world's net population growth will happen through 2050. India alone will add 220 million people. Nigeria, Pakistan, Indonesia, and the Philippines will add another 340 million combined. The United States will add 39 million. The European Union will lose population outright. The buyers and suppliers of cross-border commerce in 2040 live in different geographies than they do in 2024, and stablecoins are the rail those geographies are already adopting.
AI is about to make commerce machine-to-machine. Agents will negotiate, transact, and settle on behalf of buyers and sellers at speeds and volumes no existing rail was built for. The requirements are narrow and clear: programmable, instant, API-native, cross-border-native, and traceable. Cards have interchange and identity friction. ACH and SWIFT are too slow. Real-time bank rails are domestic. Stablecoins are the only rail that meets all five conditions today.
Wex's existing footprint already overlaps the stablecoin-adoption map in two layers. Fleet card operations in eleven countries directly. Corporate Payments processing across more than 210 countries with 20-plus currencies. Stablecoins fix problems Wex's customers already have.
Stablecoin rails extend Corporate Payments and Mobility into routes and supplier types that virtual cards cannot reach economically. The result is new addressable market and a protected buyer relationship.
Booking.com, OTAs, and corporate AP buyers route long-tail EM payments around Wex's product. The Corporate Payments take rate compresses over the next three to five years.
Wex VC's first job in this category is not financial return. It is strategic signal. Investing in this layer at seed stage shows what Wex's commercial-flow customers will be doing with stablecoins in two to three years. A $2 million check buys partner-network access and product-roadmap visibility worth more than the upside on the financial position alone.
If the assignment is two dimensions, they are regulatory durability and local liquidity depth. Both are the opposite of what a typical seed-stage software bet weighs heavily. Both share a property that makes them work as filters: they compound over years, cannot be faked, and are nearly invisible in pitch decks. Every other dimension a VC normally evaluates (team, distribution, tech, TAM) is still in the rubric below, but at standard weights. A seventh dimension, Wex strategic fit, is added because this is a CVC mandate, not a financial-only bet.
| Dimension | Weight | Why this weight |
|---|---|---|
| Regulatory durability | 20% | EM regulators change the rules constantly. Licenses, named bank partners, and central-bank relationships compound over years and cannot be faked. Companies arbitraging today's gap get repriced when it closes. |
| Local liquidity depth | 20% | The actual hard problem. Settling $500K to Lagos in the hour at a known FX spread takes real infrastructure: bank partners, OTC desks, pre-funded float, crisis liquidity. Invisible in pitch decks. |
| Wex strategic fit | 15% | This is a CVC mandate, not a generic seed bet. Wex's $2 million only beats a financial fund's $2 million if the company gives Wex's roadmap, M&A pipeline, or customer franchise something it actually needs. Without this dimension the rubric collapses to a generic VC ranking. |
| Team and founder fit | 15% | At seed, the team is the asset. Regulatory backgrounds, banking relationships, and target-market operator experience are the cleanest proxy for whether the two heaviest dimensions actually get built. |
| Distribution and network effects | 15% | Platform dynamics are still aspirational. The real near-term concern is concentration: a single customer often drives 60% of volume. Bank, exchange, and mobile-money partnerships compound and reduce that risk. |
| Tech and product | 10% | Mostly commoditized. Everyone integrates Circle, Bridge, Privy, or Turnkey. Pure tech moats last about six months. Real differentiation lives in compliance sophistication, vertical specialization, or novel rail combinations. |
| Addressable market | 5% | Cross-border B2B is a $200 trillion flow. Every deck cites the same McKinsey chart. Differentiates nothing at this stage. |
Filter criteria: B2B rather than consumer; emerging-market focused; check size of $2 million as a non-lead investor in either the current round or the next round. Fifteen companies were screened against the rubric above. The two picks pair an Africa-first operator with scale and unit economics already in production, and a Latin America operator that hedges the single biggest risk to the thesis.
| Company | Stage / Funding | Where they score | Verdict |
|---|---|---|---|
| HoneyCoin | $4.9M Seed, Aug 2025 (Flourish-led, Visa Ventures participated) | Africa B2B at scale. $150M monthly volume, 350+ enterprise customers, profitable. Strong distribution and TAM, durable founder. | Pick 1 · 83 |
| BlindPay (YC W25) | $3.3M Seed, Aug 2025 | Latin America API that uses Pix and SPEI as the on-ramp. $30K to $10M monthly volume in 14 months. Best Wex strategic fit on the list. | Pick 2 · 78 |
| Juicyway | $3M pre-seed Nov 2024 (P1 Ventures-led) | Best disclosed proof of EM payment volume on the list ($1.3B since launch). Africa overlap, but smaller team and earlier than HoneyCoin. | Shortlist · 81 |
| Caliza | $8.5M Seed Sep 2024 (Initialized-led) | Strongest disclosed LATAM regulatory and bank-partner posture on the list. Less route-level liquidity proof than the picks. | Shortlist · 79 |
| Mansa | $10M Seed Feb 2025 (Tether-led) | Highest score on the hardest dimension (liquidity). B2B2B model sold to other fintechs limits direct Wex strategic fit. | Shortlist · 78 |
| TransFi, Cedar Money, Shield | Various | All credible, all scored 75 to 80. Either less differentiated, less Wex-relevant, or covered better by one of the picks. | Shortlist |
| XWeave, Infinite | Early seed | Strong teams and product architecture but no proof yet that the no-prefunding / SWIFT-replacement positioning works at volume. Re-evaluate in 12 months. | Too early |
| Bridge, Yellow Card, Conduit, BVNK | $36M Series A through $1.1B exit | All past the $2M non-lead stage. | Too late |
| Kontigo (YC) | $20M Seed Dec 2025 (DST-led) | Consumer-first product. A Q1 2026 hack and sanctioned-flow allegations raise diligence flags. | Wrong fit |
| Karsa, Blaze, Felix Pago, Mural Pay | Varies | Consumer remittance or stale (no follow-on since 2022). Not B2B at the stage Wex needs. | Wrong fit |
Scores are rounded to the nearest whole point on the 100-point rubric. The two picks are not the highest theoretical scorers on every individual dimension. Mansa beats both on liquidity. Caliza beats both on regulatory durability. The picks win on the weighted total and on the Wex strategic fit dimension, which is what matters for a CVC mandate.

Most stablecoin infrastructure at this stage is pre-volume. HoneyCoin is already on the other side: ~$1.8B annualized across 45+ countries, 350+ enterprise customers (Yellow Card, Onafriq), profitable. The investor syndicate is the tell. Flourish Ventures led with Visa Ventures, TLcom, and Stellar Development Foundation participating. Visa does not back African fintechs at seed casually.
Founder David Nandwa is 24, Kenyan, and advises the Kenyan Parliament on crypto policy. Regulatory durability in Africa is not built through outside counsel. It is built through relationships with the people writing the rules, and HoneyCoin's founder is in that room.
HoneyCoin operates in 11 of the same countries where Wex already has Mobility, Corporate Payments, or Benefits exposure. The product reaches the part of cross-border that virtual cards cannot: African supplier payouts, mobile-money settlement to drivers and merchants, currency-shock-resistant FX. A $2M non-lead buys roadmap visibility and a credible path to a Wex Mobility partnership or a $75 to $150M strategic acquisition in 2027 to 2028, before African stablecoin infrastructure becomes contested by the global processors.
Seed is closed. The entry point is the Series A in 12 to 18 months, which Flourish and Visa Ventures will likely anchor. Track Wex VC's $2M non-lead toward that round.
Most LATAM stablecoin companies treat Pix and SPEI as competitors. BlindPay treats them as the on-ramp. Their integration moves money from a USD account through USDC into Pix, SPEI, PSE, or Argentine Transfers, hitting a local bank account in seconds. The position holds whether the broader thesis breaks bull or bear: if real-time rails win, BlindPay wins as the orchestration layer; if stablecoins win, BlindPay wins as the bridge. A structurally unusual position for a seed-stage company.
Latin America is already in Wex's footprint: Brazil through Repom and the Salvador technology center, Mexico through Corporate Payments. BlindPay's API extends acceptance to long-tail LATAM suppliers that virtual cards cannot reach economically. A $2M investment positions Wex as a strategic partner today and a potential acquirer later. A $50 to $100M acquisition in 2027 to 2028 would give Wex a LATAM stablecoin product before a competitor builds the same thing.
BlindPay will likely raise a $10 to $20M Series A in the next 12 to 18 months. That is the round Wex VC should track toward today.
Two scenarios collapse the thesis. One threatens the LATAM pick. The other threatens the Africa pick. The two picks are chosen so that each one hedges the risk that hits the other.
Both picks could be wrong about the next three years. The portfolio is constructed so that the scenario that kills one pick is the scenario the other pick is designed to survive. The Africa pick has scale and partner-network positioning. The LATAM pick has rail-agnostic architecture. Together they cover the two ways the underlying thesis can break.
Desk research has its limits. Next step is to make some calls.
