Six years ago I drew coastlines and trail networks. Now I spend most weeks turning blockchain data into maps: where the validators actually sit, how value moves between chains rendered as something a human can read. The work is still cartography. The clients just pay in stablecoins.
That last part broke my company card before I understood why.
The money showed up fine. Spending it was the problem.
A protocol in Singapore commissions a set of network maps. They pay in USDC, in an afternoon, no wire sitting in limbo for a week. Lovely. Then the balance sits in a company wallet, and every business expense I have (the mapping software licenses, the cloud rendering, the contractor in Lisbon who does my typography) wants a normal card and a normal currency.
For a while I did the clumsy dance. Move stablecoins to an exchange, sell for dollars, wait for the dollars to reach the business account, spend from the company debit card. Three steps, two fees, and a conversion spread I could never quite see clearly, on every single expense.
What actually fixed it
A founder I make maps for asked why I wasn’t funding the spend straight from the stablecoin balance. I didn’t have an answer, so I looked into a corporate card that runs on stablecoins instead of a credit line.
The shift is small to describe and large to live with. The card spends the company’s own stablecoin balance. There’s no convert-to-dollars-first step, because the conversion happens at the point of sale, once, in front of me. The money leaves the company balance when the card taps, not three days later when a pending charge finally decides to commit.
A few things surprised me.
The spend is money we already have. A corporate credit card is a short loan the company pays back later. Funding a card from a balance we already hold means I can’t hand a contractor a payment the business doesn’t actually have yet. For a studio whose income arrives in lumps, that’s calming in a way I didn’t expect.
The fees moved into the light. My old setup charged a spread when I sold stablecoins for dollars, quietly, off where I’d never look. The card charges a conversion fee too, but it’s on the transaction, a number I can compare. I’d rather pay a fee I can see.
The record builds itself. Every purchase lands already tagged: the merchant, the category, the moment it cleared. My month-end admin used to eat most of a day, digging receipts out of email. Now it’s about 20 minutes, and I get that time back to draw.
When the boring setup still wins
I haven’t thrown out the normal account. Clients who pay in plain dollars, and most still do, land in the normal account and get spent the normal way. The credit line is occasionally useful. I’m not routing every coffee through a wallet for sport.
The rule I landed on is simple. Match the card to the shape of the money. Income that arrives as stablecoins gets spent from the stablecoin card, because forcing it back into dollars first pays a toll for nothing. Income that arrives as dollars stays on the old card.
Turns out the business under the maps runs on the same principle as the maps themselves. Work out how the thing actually moves, then draw the route that wastes the least.
