Karsa Is Building a Dollar Bank Account for People Who Can't Get Dollar Bank Accounts

The Macro: Currency Depreciation Is a Tax on Being Born in the Wrong Country

If you hold your savings in Turkish lira, Nigerian naira, or Argentine pesos, you’ve been losing money for years. Not because of bad investments. Not because of overspending. Just because the currency your paycheck arrives in keeps sliding against the dollar. The lira lost roughly 80% of its value against USD between 2018 and 2024. The naira fell more than 70% in a single year after Nigeria’s central bank floated the currency in mid-2023. Argentina’s peso depreciation is so extreme it barely registers as news anymore.

People in these countries are not unaware of the problem. They are actively, desperately trying to solve it. Black market dollar exchanges thrive in Lagos, Cairo, and Buenos Aires. Crypto adoption in emerging markets is significantly higher than in the US or Europe, and it’s not because people are speculating on memecoins. They’re trying to park their savings somewhere that won’t lose 30% by December.

The existing solutions range from clunky to predatory. USDT and USDC are useful but require crypto literacy and wallet management that most people don’t have. Traditional dollar accounts at international banks have minimum balances that are laughable for a teacher in Karachi. Wise and Payoneer serve cross-border freelancers well, but they’re not really savings products.

What’s missing is a product that works like a normal bank app, offers dollar-denominated savings with real yield, and doesn’t require a US address or $10,000 minimum balance. That gap is enormous. We’re talking about 100 million people on the conservative end, probably closer to a billion, who would use this product tomorrow if it existed and they trusted it.

The Micro: A Dollar Account That Runs on Stablecoins Under the Hood

Karsa is a neobank that gives users a USD account backed by stablecoins. You download the app, fund your account, and your money sits in dollar-denominated stablecoins earning 4-5% yield. You get a virtual Visa card (physical is coming soon) to spend online and in person. You can send money to any bank account globally.

The crypto infrastructure is largely invisible to the end user. This is not a wallet app where you need to understand gas fees and seed phrases. It looks and feels like a banking app. The stablecoin layer is the engine, not the interface.

Shahryar Hasnani and Dale Wilson are the founders, both out of New York and part of YC’s Winter 2025 batch. Shahryar previously ran business development at an Ethereum infrastructure startup. Dale was protocol development lead at a layer 1 AI blockchain. They’re crypto-native builders who seem to understand that the mass market doesn’t care about blockchain architecture. It cares about not losing money.

The product is live on both iOS and Android. The landing page lists compatibility with Upwork, Fiverr, Binance, and PayPal, which tells you who the initial target users are: freelancers in emerging markets who earn in dollars through platforms but live in countries with unstable currencies. That’s a smart wedge. These users already have dollar income. They just need somewhere better to keep it.

The competitive field includes Accrue (dollar savings for non-US residents), Chipper Cash (pan-African fintech), and various crypto-native products like Lemon in Argentina. Karsa’s bet is that combining stablecoin yield, a Visa card, and a clean banking UX in one app is the combination nobody has nailed yet.

The Verdict

I think Karsa is going after one of the biggest underserved markets in fintech, and the product design choices suggest they understand the user better than most crypto-adjacent companies do. Hiding the stablecoin infrastructure behind a banking interface is the right call. Most people don’t want to understand how their savings are denominated at the protocol level. They want to know their money is safe and growing.

The risk is regulatory. Every country with a weak currency also has a government that gets nervous when its citizens start parking their savings in dollars. Nigeria has cracked down on crypto exchanges. Turkey has imposed capital controls. Argentina changes its currency rules roughly every fiscal quarter. Karsa will need to navigate this country by country, and any one government decision could shut them out of a major market overnight.

At 30 days, I’d want to see deposit volume from their first cohort of freelancers. At 60 days, I’d want to know if users are treating it as a savings product (sticky) or a transfer corridor (transactional). At 90 days, the question is whether they’ve started expanding beyond freelancers into the broader mass market, because that’s where the billion-user number lives or dies. The product is clean, the team gets the space, and the market pull is undeniable. Execution in hostile regulatory environments is the whole ballgame.
