One Cash

I own 11 different crypto wallets.

I can’t remember why I downloaded most of them. One was “better for NFTs.” Another had “lower fees.” A third was “more secure.” The rest exist because some airdrop required them, or some chain wasn’t supported, or some dApp only worked with that specific one.

You know what I call this? The illusion of choice.

When options become obstacles

Psychologist Barry Schwartz wrote about “The Paradox of Choice“—the more options people have, the more anxious and less satisfied they become. His research showed that when faced with 24 jam varieties, customers were 10 times less likely to buy than when they saw just 6.

Crypto has about 300 jam varieties. And we call that “decentralization.”

But here’s what actually happens: someone wants to pay you in crypto. You send them your wallet address. They say “which chain?” You say “Ethereum.” They say “I only have USDC on Polygon.” Now you need to download a new wallet, or figure out a bridge, or explain why you can’t accept their money.

This is not freedom. This is friction wearing a disguise.

The custody paradox

The same thing happened with custody. We went from “not your keys, not your coins” to a situation where most people can’t even keep track of which coins are in which wallet, on which device, secured by which recovery phrase.

I know people who’ve lost access to thousands of dollars because they have crypto scattered across 15 different wallets and can’t remember which mnemonic goes where. The freedom to choose your own custody model turned into the burden of managing seven different security systems.

What standardization actually means

People hear “standardization” and think “centralization.” They’re not the same thing.

USB-C is a standard. You can still choose your cable manufacturer, your device, your use case. But you know that when you plug it in, it will work. That’s not centralization. That’s interoperability.

The internet has protocols—HTTP, TCP/IP, SMTP. These are standards. They don’t limit what you can build. They enable everyone to build together, and trust that their creations will talk to each other.

Right now, crypto is like the internet in 1987, when every network used a different protocol and nothing connected. We called it “freedom to innovate.” It was actually just chaos.

The path forward

OneCash isn’t trying to eliminate choice. We’re trying to eliminate the paralysis that comes from having too many incompatible choices.

You should be able to choose your favorite wallet, your preferred chain, your security model. But when you want to pay someone, that should work automatically—regardless of what choices they made.

That’s not limiting freedom. That’s fulfilling the actual promise of cryptocurrency: money that works like the internet, accessible to anyone, anywhere, instantly.

My grandmother doesn’t need 47 jams. She needs the one that tastes good and doesn’t expire before she uses it.

Same goes for money.

My grandmother keeps $2,000 in cash under her mattress.

When I asked her why, she said: “Banks are complicated. ATMs have too many buttons. At least I know where my money is.”

She’s 78, sure. But here’s what bothers me: crypto people would say the exact same thing about their wallets today. “I know where my Bitcoin is. I know where my Ethereum is. I know where my Solana is.”

Congratulations. You’ve built something your grandmother would understand perfectly. Which means you’ve failed.

Think about what “money” means. When you hand someone a $20 bill, you don’t explain the Federal Reserve. You don’t discuss monetary policy. You don’t clarify which bank issued it. You just… pay.

That’s what cash does. It abstracts away everything you don’t need to know.

Now look at crypto. To send someone money, you need to know what chain they’re on. You need matching wallets. You need compatible protocols. You need to understand gas fees, bridge protocols, and custody models.

We took the simplest human invention—money—and made it complex again.

The grandmother test

Here’s a thought experiment. Give your grandmother three envelopes:

• One with $100 in US dollars
• One with 0.0015 BTC
• One with a seed phrase to a wallet containing $100 in mixed crypto assets

Which one can she actually use? Which one actually functions as money?

The dollar wins. Not because it’s superior technology. Because it’s standardized. Every merchant accepts it. Every person recognizes it. Every transaction works the same way.

Why fragmentation kills adoption

Most crypto advocates think complexity is a feature. “You need to educate yourself,” they say. “Learn about blockchain. Understand the technology.”

But money doesn’t work like that. Nobody takes a course in monetary theory before buying groceries. The whole point of currency is that you don’t need to understand it to use it.

When you have 50 different chains, 200 different wallets, and thousands of different tokens—each with their own rules, fees, and transfer methods—you haven’t built money. You’ve built a hobby for people who enjoy spreadsheets.

Meanwhile, Venmo moves billions of dollars a day. Why? Because when you want to pay someone, you type their name and press send. That’s it. No chain selection. No gas optimization. No custody concerns.

My grandmother will never use crypto as it exists today. Neither will your barista. Neither will 99% of humanity.

And until we fix that, we’re just building expensive databases for each other.
