Stablecoin Infrastructure for Emerging Markets

Most stablecoin commentary focuses on disrupting U.S. cards and SWIFT. That could take decades to play out. This memo focuses on what is already happening: stablecoins are becoming the preferred rail 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 are different. They solve real problems for the kind of customer Wex already serves. They also compress the economics of how Wex serves those customers today. Both sides of that tension are in scope for this memo.

What follows is an evaluation of the space, a framework for assessing companies in it, and two companies worth a closer look. The goal is to surface where this layer might matter to Wex VC, not to assert that any specific check should be written.

First, a brief primer.

A stablecoin is a digital token pegged 1:1 to the US dollar, backed by reserves at the issuer (Circle, Tether, PayPal, and increasingly banks like JPMorgan). They exist because they let dollars move at blockchain speed for fractions of a cent, 24/7, anywhere with an internet connection. The chart below compares how money actually flows from a US buyer to a Brazilian vendor under each rail, with approximate fees at each step.

Part 1Why now? Why emerging markets?

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.

REASON 1

The gray area got federal endorsement

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.

REASON 2

Funds flow down the path of least resistance

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.

REASON 3

SpaceX demonstrates the enterprise use case

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.

REASON 4

Demographic shifts

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.

REASON 5

Automated agent commerce

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.

Part 2A stablecoin investment evaluation framework for Wex VC.

Why this matters to Wex

Wex's footprint sits inside the geographies where stablecoin adoption is happening: fleet card operations in eleven countries, Corporate Payments processing across 210+ countries with 20-plus currencies. The exposure is asymmetric. Stablecoins solve real problems Wex's customers face. They also compress the economics of how Wex serves those problems today. Any honest evaluation has to hold both at once.

Wex's three segments don't share equal exposure to this shift. Mobility ($1.39B, 52% of FY2025 revenue, flat YoY) overlaps narrowly — specific cross-border trucking and EM driver-payout use cases, but most volume is domestic US fuel cards. Benefits ($797M, 30%, +9.6% YoY) is US healthcare administration and doesn't overlap. Corporate Payments ($477M, 18%, +17.8% YoY in Q4) is where this thesis lives. Inside CP, the structure matters: roughly 75 to 80% of volume is travel (Booking.com, Expedia, OTAs paying global hotels via virtual cards), and the remaining 20 to 25% is Direct AP for construction, insurance, and corporate tail spend — the higher-take-rate slice Wex is actively expanding. The honest reading: stablecoin rails could extend Direct AP into cross-border supplier payments that today flow through wires (offense). They could also undercut card-based interchange across CP (defense). The same infrastructure does both.

Offense scenario

Wex acquires or partners into the rails its customers will use

If stablecoins become how cross-border B2B settles for Wex's customer profile, the options are: own the layer via acquisition, partner with an operator for embedded settlement, or cede the layer. A seed-stage position is optionality on the first two. It is not, by itself, an offensive product strategy.

Defense scenario

Bridge, JPMD, and Conduit approach Wex's customers directly

Booking.com, OTAs, and corporate AP buyers route long-tail EM payments around Wex's product. CP take rate compresses over three to five years. This is the more concrete of the two scenarios.

Wex VC's most useful role in this category is signal, not return. A seed-stage check buys partner-network access and visibility into what Wex's commercial-flow customers will be doing in two to three years. Whether that signal converts into commercial value depends on Wex's broader strategic response to stablecoins, which is an internal question this memo cannot answer. Without that follow-through, a passive seed position is just a small financial bet.

How to evaluate stablecoin companies

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.

Part 3Two companies worth a call.

Filter criteria: B2B rather than consumer; emerging-market focused; reachable with a $2M non-lead check in the current round or the next. Fifteen companies screened against the rubric above. Neither of the two picks is an obvious "invest tomorrow" decision. They are the best available proxies for the underlying thesis: an Africa-first operator with disclosed scale already in production, and a LATAM operator with a structurally rail-agnostic design. Both deserve a call. Neither should be committed to without internal diligence on Wex's strategic response to stablecoins, which is the question that decides whether a seed check is signal or noise.

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.

What sets HoneyCoin apart

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.

Why they matter to Wex (conditional)

Wex does not currently operate in Africa as a strategic priority. HoneyCoin only matters to Wex if Wex decides African B2B payments is a 2027 to 2028 expansion target. That decision is internal and outside the scope of this memo. If Wex is leaning that way, HoneyCoin is the highest-conviction available proxy for what the African layer looks like. If not, HoneyCoin is an interesting standalone Africa-fintech bet without a sharp strategic-fit case for Wex specifically. Being clear about which of those two stories Wex is telling itself is the first piece of diligence.

Round timing

Seed is closed. The natural entry point if Wex does choose to engage is the Series A in 12 to 18 months, which Flourish and Visa Ventures will likely anchor.

BlindPay

Pick 2 · YC W25 · LATAM

A Latin American stablecoin API that integrates with Pix and SPEI rather than competing against them. The most rail-agnostic position on the list, which is why this pick survives the LATAM real-time-rail risk in a way most peers don't.

Seed, Aug 2025

$10M/mo

Ex-PicPay and LendingClub

What sets BlindPay apart

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.

Why they matter to Wex

Latin America is already in Wex's footprint: Brazil through Repom and the Salvador technology center, Mexico through Corporate Payments. BlindPay targets exactly the customer profile Wex's Direct AP product serves, but operates on cross-border payment flows where Wex's virtual cards either don't reach economically or generate compressed margins. The strategic-fit case is more defensible than for any other company on the list, because the path to engagement does not require Wex to enter a new region. It also runs in both directions: BlindPay's rail-agnostic design competes with Wex's CP product if Wex doesn't engage, and supplements it if Wex does. That is the closest the file gets to a forced decision.

Round timing

BlindPay will likely raise a $10 to $20M Series A in the next 12 to 18 months. If Wex chooses to engage in this layer at all, that is the cleanest entry point on the list.

What could kill this.

Three risks. Two are geography-specific and the picks hedge each other on those. The third is structural and the picks don't fully hedge it.

Risk to Pick 2 (BlindPay)

Real-time bank rails win before stablecoins saturate B2B.

Pix has 150 million users. UPI has 450 million. Both began cross-border interop work in 2024.
An India and Brazil Pix-UPI interoperability agreement was signed in 2024.
These rails are real-time, near-zero cost, and require no crypto.
If global EM real-time interoperability matures quickly, the LATAM thesis collapses to a three-year window.

How BlindPay hedges this: BlindPay uses Pix and SPEI as its on-ramp rather than competing against them. If real-time rails win, BlindPay still wins as the orchestration layer. If stablecoins win, BlindPay wins as the bridge. The pick is structurally chosen to be agnostic to which side of this question turns out right.

Risk to Pick 1 (HoneyCoin)

Mobile-money networks build stablecoin settlement natively and disintermediate the rails layer.

M-Pesa, MTN MoMo, and Airtel Money already own the African last mile.
Each has the regulatory licenses, the bank partners, and the customer base.
Adding USDC settlement as a feature would compress HoneyCoin's role to a thin API wrapper.
The African mobile-money operators are the single most credible disintermediation threat on the file.

How HoneyCoin hedges this: HoneyCoin is already operating as a partner to mobile-money networks rather than a competitor, with Yellow Card and Onafriq among its 350-plus customers. Visa Ventures and Stellar's participation in the seed round signal that the partnership thesis is the assumed path. The disintermediation scenario gets harder once HoneyCoin is the default integration layer between mobile money, banks, and the global stablecoin economy.

Risk 3 (structural, not picked-against)

The same rails that defend the CP franchise commoditize its margin pool.

Stablecoin processing fees run roughly 0.5 to 1%. Wex's card-based interchange runs 2.5 to 3.5%.
If cross-border AP migrates to stablecoin rails, the total CP margin pool shrinks regardless of who wins.
Owning seed equity in the rails does not solve this. It only buys an option to participate in the smaller pool that results.
This risk is what would prompt a "wait and watch" stance over "invest now."

Partial hedge only: a seed position pays back only if Wex follows it with operational engagement — commercial partnership, embedded settlement, or acquisition. A passive seed bet does not solve this risk; it just makes Wex's exposure to the disruption slightly less embarrassing if the disruption happens.

Honest read

Both picks face correlated risks (regulatory churn, technology commoditization, customer concentration). The geography-specific hedges above isolate the two largest such risks. They do not eliminate the underlying structural risk that this entire layer compresses faster than the picks can scale. That risk is what makes the investment a question about Wex's operational follow-through, not just about the picks themselves.

What we need to uncover next.

Desk research has its limits. Next step is to make some calls.

1

Wex's strategic posture toward stablecoins. Whether Wex sees this layer as defense (acquire or partner before disruption), offense (build via M&A), or noise (let it play out, react later). Each implies a different check size, timing, and operational commitment. A $2M non-lead seed only makes sense under the first two. This is the diligence that decides whether anything else here matters, and it lives entirely inside Wex.
2

Unit economics on both picks. Volume is semi-public. FX spread, take rate, and gross margin are not. HoneyCoin's profitability claim at $150M monthly is unusual at seed and worth pressure-testing.
3

Customer concentration on HoneyCoin. Yellow Card and Onafriq are publicly named customers. If those two account for the bulk of the $150M monthly volume, the business looks materially different than the headline number suggests.
4

Wex internal roadmap. Whether Conferma, Extend, Sabre, or Mastercard already have stablecoin orchestration plans of their own. Investing in something Wex's own ecosystem will undercut is the worst-case outcome. This is the fastest piece of diligence available and should happen before the first founder call.
