Building the Rails
I’ve spent my career on payment rails. First moving money across borders the old way, then helping take a crypto staking protocol past $500M+ in deposits, now on the unglamorous plumbing that lets a crypto balance behave like money you can actually spend. People assume the exciting part of crypto is the speculation. I think the exciting part is the boring part, and the boring part is the only part that lasts.
Took me years inside both worlds to see this clearly: traditional payments and crypto aren’t enemies. Same problem, different layers, and almost everyone arguing about it is confused about which layer they’re standing on. The job, always, is to move value from A to B such that both sides trust it happened. Visa solved this with a vast web of institutions, settlement networks, and trust stacked up over decades. Crypto tries to solve it with math and code instead of institutions. Identical goal. Only the trust mechanism differs, who or what you have to believe.
That reframing kills most of the noise. The crypto maximalist who thinks banks are obsolete has never sat through real cross-border settlement and watched how much hard-won machinery keeps money from just vanishing. The TradFi skeptic who thinks crypto is purely a casino has never felt value move across the world in seconds with no intermediary asking permission. Both are right about the other’s weakness and blind to their own. The interesting work is exactly at the seam. Building the rails where one trust model hands off to the other, where a crypto balance becomes a swipe at a checkout, where math-trust converts cleanly into institution-trust. That seam is where money actually lives now.
And the seam is almost entirely schlep. The part everyone wants, the token, the protocol design, the part you can tweet, is packed with brilliant easily-bored people. The part that makes it real, the reconciliation, the settlement edge cases, the compliance plumbing that makes the magic legal, the off-chain machinery nobody sees, is nearly deserted, and it’s the only part that decides whether real money flows or doesn’t. The unsexy work is the moat, precisely because it repels the people who only want the exciting parts.
There’s a deeper reason this is worth a career. Money is just stored trust. A memory of value owed that everyone agrees to honor. Build payment rails and you’re not really building software. You’re building a new way for strangers to trust each other at a distance, one of the oldest and most consequential things humans have attempted. The deists who founded America got that a functioning society runs on durable trust between strangers. Franklin obsessed over the post, over currency, over the boring infrastructure that lets a republic of strangers actually cohere. Rails are civilization’s load-bearing walls. You don’t see them until they fail.
So when people ask why I work on payments instead of something flashier, the honest answer is the rails are the most important software in the world, and the most important software is almost always the least glamorous. The flashy stuff rides on top of rails someone built in the dark. I’d rather be the person who built the rail than the person who tweeted from the train.
