BASIN · CW · XCG
Curaçao changed currency in 2025. The Caribbean guilder replaced a code that had been stable for decades, which is the cheapest possible reminder that a currency belongs in a column rather than in the source.
Not decoration. Every one of them is a field in something we have shipped.

Money in Curaçao. Curaçao is on the Caribbean guilder (XCG), pegged at 1.79 to US$1.00. A stable peg is a gift and a trap: because the rate does not move, teams start treating the two currencies as interchangeable.
They are not. An amount is a number and a currency, and two amounts in different currencies added together are a number in no currency. We store integer minor units with a currency code, convert only at an explicit boundary, and never compare across currencies without converting first.
Four lines, one studio. The same stack builds all of them, which is why the hardware and the app talk to each other.
Tier 1 · Fete Labs
Product engineering for businesses and institutions in Curaçao: web applications, back offices, booking and ordering systems, payments integration and the data layer underneath them. Scalable architecture, type-safe low-latency code, infrastructure built to stay up.
Brief the labTier 1 · Seed
The FetePASS ecosystem covers Curaçao as one of twenty-nine island editions: tickets, food, bookings and a local feed on one pass. Currently in private preview.

Outdoor hotspot hardware for venues, events and public spaces. Lab Release 01, and the proof that this studio ships things you can touch as well as things you can log into. Agents wanted in Curaçao.

For new and young businesses: a managed domain-and-site lease where we handle everything, or a custom launch on a domain you already own, built and handed over with the keys.
