Stablecoins in the Wild: When Fintech Discovers Programmable Money
This article is authored by Arthur Firstov, the Chief Business Officer at Mercuryo, a world chief in crypto funds infrastructure. Arthur is a acknowledged voice on stablecoins, digital banking, and the convergence of web3 and conventional finance – and this text is predicated on his insights from partnerships with greater than 300 corporations, together with Circle, Coinbase, Mastercard, Revolut, and Polymarket.
As the digital property market matures past hypothesis, a brand new part of world finance is rising, one outlined by interoperability, compliance, and inclusion. Speaking at Token2049 Singapore 2025, Arthur Firstov outlined how the subsequent evolution of monetary techniques is closing the hole between decentralized finance (DeFi) and conventional monetary establishments.
The dialog targeted on a easy thought with huge implications: the worlds of crypto and mainstream finance are not parallel universes. They are converging to construct accessible, environment friendly, and clear international markets for each institutional and retail individuals.
A Payment Layer for the Digital-Asset Era
“Stablecoins have gotten the new fintech,” says Firstov, who believes that in the subsequent few years, each fintech firm will, in impact, be a stablecoin firm.
The information helps this trajectory. Recent analysis reveals that stablecoin transfers for funds have already reached roughly $19.4 billion year-to-date in 2025 and are on tempo to surpass $1 trillion yearly by 2030, only for the rising funds use circumstances, not speculative buying and selling. At the similar time, McKinsey now estimates that complete stablecoin transaction quantity throughout all use circumstances has already topped $27 trillion a yr, placing it on a possible path to overhaul legacy networks earlier than the decade is out.
That development highlights how shortly the narrative has shifted from “crypto buying and selling” to “digital settlement rails.”
“In follow, the expertise is seamless. Users should buy digital property with a debit card or Apple Pay, convert them into stablecoins, ship worth globally in seconds, and money out to a checking account,” Firstov explains.
Behind that simplicity is an increasing community of wallets, fintechs, and international fee rails working collectively to energy prompt, borderless transfers, the basis of a brand new digital-asset settlement layer for the fashionable financial system.
From Skepticism to Scale: Klarna, Tempo and the New Rails
One of the clearest alerts that this shift is actual comes from names that, till not too long ago, had nothing to do with crypto.
In late 2025, Swedish digital financial institution Klarna, greatest recognized for its “purchase now, pay later” companies, introduced KlarnaUSD, its first U.S.-dollar stablecoin, constructed on Tempo, a brand new payments-focused blockchain developed by Stripe and Paradigm.
KlarnaUSD is issued by way of Bridge’s Open Issuance platform (a Stripe firm) and is at present stay in take a look at mode, with a full launch on Tempo’s mainnet deliberate for 2026. Klarna explicitly frames the transfer as a approach to:
– Bypass costly, gradual cross-border fee routes
– Tap right into a $120 billion annual cross-border charge pool
– Serve over 100 million current clients on cheaper, programmable rails
For Firstov, this sort of partnership is strictly what “closing the hole” appears like in follow:
“When a digital financial institution like Klarna launches a stablecoin on a devoted funds blockchain, the story is not ‘crypto individuals sending tokens to one another.’ It is mainstream fee corporations quietly rewriting their settlement stack on prime of stablecoin rails.”
Moves like KlarnaUSD on Tempo sit in the similar class as PayPal’s PYUSD and different institution-led experiments: they’re early, managed, and compliance-heavy, however they reveal the place the trade expects the actual development to return from.
Who Is Using It and Why
“The digital-assets viewers often consists of blockchain fans and builders driving innovation in the area,” Firstov says.
But he provides that the person base now extends far past tech insiders:
– Digital nomads managing earnings throughout borders
– People with households overseas sending remittances
– Aspiring founders and freelancers getting paid globally
– More subtle customers exploring new digital-asset merchandise and yield alternatives
This number of customers displays the rising variety in entry. In Latin America and Southeast Asia, the place native currencies typically face extreme volatility, stablecoins are more and more used as on a regular basis banking options fairly than speculative property.
The macro numbers underline the shift. The international stablecoin provide has pushed previous $300 billion, signaling that that is not a distinct segment phase. Meanwhile, new analysis from Protocol Theory (in partnership with Mercuryo) reveals that in the U.S. solely 12 p.c of adults really feel web3 wallets match their lives, in contrast with 64 p.c for conventional digital wallets. That hole highlights each the remaining friction and the measurement of the alternative to make self-custodial experiences as intuitive as the apps individuals already use each day.
Liquidity, Infrastructure and Market Movement
“The actual battlefield at the moment is infrastructure,” Firstov insists. “It doesn’t matter which chain you utilize; what issues is that the rails work round the clock, globally.”
Recent reviews again this up: fee volumes in B2B stablecoin settlements jumped from beneath $100 million monthly in early 2023 to greater than $3 billion month-to-month in early 2025. That sort of development calls for severe plumbing:
– Multi-chain settlement
– Real-time routing
– Robust international compliance and sanctions screening
– Institutional-grade custody and auditability
This is the place examples like KlarnaUSD on Tempo are instructive. Tempo is purpose-built for funds, and Klarna is utilizing it not as a advertising and marketing gimmick, however as a approach to decrease settlement prices for retailers and customers at scale.
Meanwhile, establishments are waking up extra broadly. Tokenized real-world property (RWAs) might attain $2 trillion by 2028, with stablecoins performing as the underlying “plumbing” that strikes worth between markets and devices. Firstov factors to ETF-style flows, digital asset token (DAT) liquidity channels, and controlled rails as early previews of what’s coming subsequent.
The “Golden Era” for Users
“We are getting into the golden period for customers,” Firstov says. “The greatest monetary establishments and blockchain platforms at the moment are competing for distribution. As a end result, customers can entry new monetary merchandise and markets, from stablecoins to tokenized property, with charges close to zero and virtually no premium.”
That is a daring declare, however the numbers give it weight. Cost reductions of as much as 99 p.c have been reported in cross-border transfers utilizing stablecoin rails in comparison with legacy correspondent banking. And as Klarna, PayPal, Stripe, Revolut and others deploy stablecoin-based rails, the taking part in area is shifting from early adopters to international scale.
In impact, customers are getting the upside of institutional competitors: cheaper transfers, sooner settlement, and entry to new merchandise, whereas the heavy lifting occurs behind the scenes in infrastructure.
Final Take
Arthur Firstov and his friends are working at a uncommon inflection level. The merging of DeFi, stablecoins, and institutional finance alerts a future the place cash strikes anytime, anyplace, immediately, and cheaply.
What as soon as seemed like two separate universes, crypto on one facet and banks and fintechs on the different, is quickly turning into a single, programmable monetary material. KlarnaUSD on Tempo is one concrete instance; the subsequent wave will convey extra banks, extra stablecoins, and extra tokenized property onto related rails.
As the underlying infrastructure matures, liquidity deepens, and regulatory readability expands, the promise of programmable cash is not theoretical. The mission now is not only innovation however inclusion, making certain that from retail customers in Argentina to hedge funds in New York, everybody can plug into the similar digital-asset financial system.
