Traveling Between Argentina and Brazil? Stop Losing Money Every Time You Cross the Border
Every border crossing means a new currency, a new payment system, and another round of exchange rate losses. One app. One balance. Both countries. No fees.
Traveling Between Argentina and Brazil? Stop Losing Money Every Time You Cross the Border
You move between countries. Maybe you live in Buenos Aires and visit Sao Paulo regularly. Maybe you travel across Latin America for work or pleasure. Every border crossing means a new currency, a new payment system, and another round of exchange rate losses. Argentina runs on Mercado Pago. Brazil runs on Pix. Neither accepts the other's payment methods. Every conversion takes a cut.
One app. One balance. Both countries. No fees.
The Problem: Different Payment Systems, Multiple Conversions, Constant Losses
Frequent travelers between Argentina and Brazil — and across Latin America more broadly — face a unique set of frustrations that tourists and residents do not.
Different Payment Systems in Every Country
Argentina's dominant payment method is Mercado Pago QR. Brazil's is Pix. These systems do not interoperate. If you have a Mercado Pago wallet in Argentina, it does not work in Brazil. If you have Pix access in Brazil, it does not work in Argentina. Crossing the border means starting over with payments.
Multiple Currency Conversions
Every time you convert money, you lose a percentage. Travel from Argentina to Brazil and you convert ARS to BRL (or go through USD as an intermediary). Come back and you convert again. Each conversion involves exchange rate markups and fees. Over multiple trips, these compounding losses add up to hundreds or thousands of dollars per year.
Card Rates Are Terrible for Both Countries
Using a card in Argentina converts at the MEP rate — 10-25% worse than the market rate. In Brazil, cards trigger IOF (up to 3.5%) plus foreign transaction fees. A card that gives you a bad deal in one country gives you a bad deal in both.
No Single Solution Exists
Wise gives you a multi-currency account, but it cannot scan a Mercado Pago QR or send a Pix without a local ID. It also uses the MEP rate in Argentina. There is no mainstream financial product that lets you pay locally in both Argentina and Brazil from a single account, at the real market rate.
The Core Problem
Every country has its own payment system, its own currency, and its own set of barriers for foreigners. If you move between countries, you are constantly converting, constantly losing money, and constantly locked out of the most convenient payment methods.
How Peanut Solves This
Peanut gives you a single balance in digital dollars that works in both Argentina and Brazil. Pay via Mercado Pago QR in Argentina and Pix in Brazil — from the same account, at the real market rate, with no fees.
-
One account, both countries. Your Peanut balance works in Argentina and Brazil. No separate wallets, no separate accounts. Cross the border and keep paying.
-
Best available rate in each country. In Argentina, Peanut converts at the cripto dolar rate — approximately 5-8% better than the MEP rate (estimate, as of 2026). In Brazil, you save up to 3.5% because IOF does not apply to Peanut's conversion. You get the best deal in every country you visit.
-
No double conversion. Your balance stays in digital dollars. When you pay in Argentina, it converts once: digital dollars to pesos. When you pay in Brazil, it converts once: digital dollars to reais. No ARS-to-BRL conversion. No intermediary currencies eating your money.
-
No local ID needed in either country. No DNI in Argentina. No CPF in Brazil. Verify once with your passport from any country and pay in both. Verification takes under 2 minutes.
-
No fees. Deposits free. Payments in Argentina free. Payments in Brazil free. Withdrawals free.
Where It Works
Argentina
Pay at over 1,000,000 merchants with Mercado Pago QR — the same payment system used by local residents. Supermarkets (Carrefour, Dia, Coto, Jumbo), restaurants, cafes, kiosks, clothing stores, pharmacies, and street food vendors all accept Mercado Pago.
Need cash? Withdraw pesos from Red ATMs in Buenos Aires, Cordoba, Mendoza, Rosario, Bariloche, Salta, and Ushuaia using a QR code.
Rate advantage: Approximately 5-8% better than the MEP rate used by cards and Wise (estimate, as of 2026). On $1,000 of spending in Argentina, that is $50-$80 saved compared to Wise, and up to $200-$250 compared to cards.

Brazil
Pay at virtually every merchant in Brazil with Pix — restaurants, supermarkets, gas stations, ride-hailing (Uber, 99), hotels, online stores, and street vendors. Over 150 million Pix users nationwide. Instant, 24/7/365.
Rate advantage: Save up to 3.5% — IOF does not apply to Peanut's conversion. Traditional transfers and credit cards are subject to IOF. Peanut is not.
Everything about Peanut in Brazil
The Argentina-Brazil Corridor
This is the most common cross-border corridor in South America. Peanut is built for it. Pay in Buenos Aires on Monday, fly to Sao Paulo on Tuesday, and pay with Pix on Wednesday — all from the same balance. No conversion between ARS and BRL. No new account setup. No additional verification.
As Peanut expands to more countries (Mexico, Colombia, Peru, and others are on the roadmap), your single balance will work in even more places across Latin America and beyond.
