Stablecoin startup Rain has crossed a threshold its CEO is using to reframe the adoption debate: more than 100,000 merchants are now settling stablecoin-originated payments through Rain's infrastructure without having made any change to their payment setup, CEO Farooq Malik said in an interview published Wednesday by The Block. The payments clear through Visa's standard three-day settlement cycle, meaning merchants see ordinary card transactions on their end while Rain handles the crypto conversion behind the scenes.

How the Invisible Settlement Works

Rain holds Visa Principal Member status, which allows it to issue Visa-branded cards directly and authorize transactions across multiple blockchains. When a cardholder spends using a stablecoin balance (such as USDC or USDT), Rain's system converts the value and routes it through Visa's network in what Rain describes as a few hundred milliseconds. Merchants receive fiat on Visa's standard timeline. No crypto integration is required on the merchant side, and no notification is sent. The 100,000 figure therefore does not reflect merchants who chose to accept crypto. It reflects merchants who already accept Visa.

Rain acquired a company called Fern and its Multiplex cross-chain routing engine, which handles the movement between different blockchains and fiat without user input. The combined system processes transactions from any supported stablecoin on any supported blockchain and delivers them to any of the roughly 150 million Visa-accepting locations worldwide.

"Stablecoins are quickly becoming the way money moves in the 21st century, but adoption by users worldwide requires cards and apps that just work," Malik said previously, at the time of the company's Series C announcement in January 2026.

Scale and Funding

Rain reported more than $3 billion in annualized transaction volume as of early 2026, with its active card base growing 30 times year over year and annualized payment volume up 38 times over the same period. The company raised a $250 million Series C in January 2026 led by ICONIQ Capital, bringing total funding past $338 million and valuing Rain at $1.95 billion according to Fortune. Investors in the round included Dragonfly, Bessemer Venture Partners, Lightspeed, Galaxy Ventures, Sapphire Ventures, FirstMark, Norwest, and Endeavor Catalyst.

Kamran Zaki, a partner at ICONIQ, cited Rain's regulatory positioning alongside its technical scale: "Rain demonstrates full-stack technology, regulatory readiness, and real-world scale, positioning it as a platform enterprises can rely on."

Western Union's "Stablecard," built on Rain's infrastructure, is the most visible enterprise deployment to date. It delivers remittances as USDPT, a Western Union proprietary stablecoin on Solana, which recipients can spend at any Visa-accepting merchant upon receipt, according to fintech newsletter Connecting the Dots.

Why This Matters in South Asia and Africa

The invisible-settlement model has direct consequences for two regions where stablecoin use is already widespread but formal infrastructure has lagged.

India ranks first globally in Chainalysis's 2025 Crypto Adoption Index. Pakistan ranks third, and Bangladesh ranks fourteenth. India receives approximately $120 billion in remittances annually, and the average cost of sending $200 there runs around 5.30 percent as of Q3 2025. Traditional global remittance costs average 6.4 percent against a United Nations target of 3 percent. Stablecoin rails can operate at below 0.1 percent, a cost reduction that represents a meaningful structural shift for high-volume corridors. Rain expanded its Visa membership into Asia-Pacific in March 2026, with first program launches targeted for the second quarter of 2026; as of publication, Rain has not issued a public update confirming the status of those launches.

"Businesses operating internationally should not have to stitch together multiple issuing partners just to launch a global card program," Malik said at the time of the APAC announcement.

Nischint Sanghavi, Visa's crypto lead for Asia-Pacific, described the collaboration in a statement: "Our collaboration with Rain reflects our focus on delivering secure, scalable payment experiences."

Pakistan's regulatory posture has also advanced considerably. The country launched a formal regulatory sandbox in the fourth quarter of 2025 with three stablecoin remittance providers in active pilot, a signal of deliberate policy engagement from a market that already ranks third globally in adoption.

In Sub-Saharan Africa, stablecoins account for roughly 43 percent of total crypto transaction volume. The region received more than $205 billion in on-chain crypto value between July 2024 and June 2025, a 52 percent year-over-year increase. Nigeria alone accounted for $92.1 billion of that figure. A 2026 YouGov study found 95 percent of surveyed Nigerian respondents would prefer to receive salaries in stablecoins over local currency. USDT on Tron has become the practical remittance standard across Nigeria, Ghana, and Kenya. Rain listed Africa explicitly as a target expansion region in its Series C use-of-funds disclosures.

The regulatory environment across the continent is also shifting. Kenya passed the Virtual Asset Service Providers Act in October 2025 and abolished a 3 percent digital asset tax in the same legislative package, materially improving conditions for stablecoin infrastructure in one of Africa's largest crypto markets. At the infrastructure layer, Flutterwave's partnership with Polygon Labs, announced in October 2025, extended USDC and USDT transfer capability across its enterprise merchant network, illustrating the scale of the ecosystem Rain is entering on the continent.

Regulatory Backdrop

The GENIUS Act, which became U.S. law on July 18, 2025, created the first federal framework for payment stablecoins. Implementing regulations were due by July 2026, with enforcement set to begin no later than January 2027; as of publication the status of those implementing regulations has not been publicly confirmed. The EU's MiCA framework and Hong Kong's Stablecoins Ordinance, which took effect in August 2025, provide parallel clarity in jurisdictions where Rain operates. Malik has said the GENIUS Act positions Rain to "hyper-accelerate" the ecosystem, shifting stablecoins from their earlier classification as speculative assets toward regulated payment infrastructure.

Visa settled $4.6 billion in stablecoin transactions in the first quarter of 2026, according to figures cited by analyst publication Insights4VC. The 100,000 merchant figure Rain announced Wednesday sits against a much larger ceiling: any of the 150 million Visa-accepting locations globally is already technically reachable. The gap between those two numbers is what Rain is building toward.
