Wherever you are, you're paying the middleman.
If you've ever tapped a card abroad, invoiced across a border, or sent money home, you've paid a spread you never agreed to.
Every tap abroad carries a ~3% card markup you never see itemised — priced into the rate itself.
The freelancer invoices overseas and loses a cut to platform FX before a dollar lands.
The "zero-fee" transfer is priced 2% off the real rate. The fee didn't vanish — it hid.
A business pays across three currencies — and gets taxed by the spread on every hop through USD.
Wages sent home lose up to 6% every month — from the people who can least afford it.
Savings melt in a currency with two rates — the official one, and the one you can actually get.
One fix, for everyone: the real rate. The spread a middleman used to pocket now flows to the community — the LPs, evangelists, and builders behind every swap. That's who you're paying now. And you can be one of them.
Even the fintechs ride the same correspondent rails underneath — they hide the friction rather than remove it. The spread Sera does charge goes to the community providing the liquidity, not to a rent collector — why FX moves onchain first →
