# RateCurb

> RateCurb compares international money transfer rates in real time. We track exchange rates, fees, and transfer speeds across providers like Wise, Remitly, Revolut, and WorldRemit so users can find the best deal for any send corridor.

## What we do

RateCurb is a remittance comparison service. For any source/destination country pair (called a "corridor"), we show:
- Live exchange rates from multiple providers
- Total fees (fixed + percentage)
- How much the recipient actually receives
- Transfer speed estimates
- Historical rate trends

We cover corridors such as USA→Brazil, USA→India, USA→Mexico, UK→India, and hundreds more.
