Brazil is one of the largest crypto markets in the world, ranked fifth in global crypto adoption in 2025, up from tenth a year earlier, with about 25 million Brazilians holding digital assets. In the first quarter of 2026 alone, Brazilians purchased $6.8 billion in stablecoins, representing 98% of all cryptocurrency bought abroad during that period, more than doubling compared to the same period in 2025.
The demand is clear: Brazilians want dollar-denominated financial tools that work globally, without the friction and costs of the traditional banking system. A crypto card is one of the most practical answers to that demand but not all cards are built with the Brazilian user in mind.
This guide explains why crypto cards are particularly relevant for Brazilians, what to watch out for, and why Amulets stands out as the strongest option for users who want to earn Solana on every purchase.
The Brazilian Problem: IOF, spreads, and dollar access
Before choosing any financial product, Brazilian users face a specific set of challenges that most international guides ignore entirely.
The IOF tax
The IOF (Imposto sobre Operações Financeiras) is Brazil's financial transaction tax. International purchases made with credit or debit cards, prepaid cards, and traveler's checks are subject to an IOF rate of 3.5% on the foreign currency value converted. This applies to virtually every traditional Brazilian card used abroad, meaning you're paying a 3.5% tax on top of whatever exchange rate and spread your bank charges.
For Brazilians who travel frequently, work with international clients, or simply use global services like software subscriptions, streaming, or cloud infrastructure, this tax accumulates fast.
The spread problem
On top of IOF, Brazilian banks and traditional fintechs typically add a conversion spread of 2–5% when converting reais to foreign currency. It's rarely disclosed clearly, but it's real and it compounds with the IOF to create total costs of 5–8% on every international purchase.
The dollar access gap
Stablecoin transactions are not currently subject to the financial taxes that apply to traditional currency movements, and President Lula suspended plans to tax stablecoin purchases and remittances ahead of the presidential election cycle. This creates a meaningful window for Brazilian crypto users: holding and spending dollar-pegged stablecoins via crypto cards is currently a more cost-efficient path than using traditional banking infrastructure for international purchases.
Why a crypto card makes sense for Brazilians
A crypto card funded with stablecoins (USDC or USDT) addresses multiple pain points at once:
Dollar-denominated spending without going through a Brazilian bank's conversion process
Global acceptance anywhere Visa or Mastercard is accepted
No IOF on the spending itself when the card is issued outside Brazil's traditional banking rails
Crypto rewards on everyday purchases, in real assets
For Brazilians who already hold stablecoins, a crypto card is simply the most logical spending layer on top of what they already own.
Amulets: the best crypto card for Brazilians who hold or want SOL
Amulets is a Solana-native payment card accepted anywhere Visa is accepted, compatible with Apple Pay and Google Pay, and built specifically for stablecoin-first users who want real crypto rewards.
Spend stablecoins, earn SOL
Fund your Amulets account with USDC, USDT, SOL, ETH or BNB. Spend anywhere Visa is accepted: online, in-store, or internationally. Every eligible purchase automatically earns cryptoback in SOL credited directly to your account. No conversion required on your end. No manual redemption.
For Brazilian users with a long-term view on Solana, this is a uniquely powerful combination: dollar-stable spending + automatic SOL accumulation on every transaction.
How the cryptoback tiers work
Every Amulets user starts at 0.5% Cryptoback in SOL. On the first day of each month, the platform reviews your previous month's spending and automatically assigns your reward tier for the next 30 days. The more you spend, the higher your tier and your rate stays locked in for the entire month.
During special Cryptoback Boost campaigns, rates can reach up to 3% in SOL on selected purchases. No subscriptions, no staking, no minimum balance required.
No hidden costs
One of the most important factors for Brazilian users specifically, Amulets is designed for international spending with:
No traditional banking markups on FX
No annual or subscription fees to start earning
No staking requirement to access any tier
This matters because most alternatives, including cards designed for Brazilian users, require you to hold a native token, or cap your monthly rewards at a level that makes the product feel symbolic rather than substantive.
Earn more by referring friends
Amulets' Referral Program is particularly well-suited to Brazil's crypto community, which is large, active, and highly networked. Share your referral link with your community, WhatsApp groups, or social media. Every time someone you referred spends with their card, you earn rewards automatically, with no ongoing effort.
If the people you refer also bring in others, your earnings compound across multiple network levels. Top referrers unlock Ambassador status with higher reward rates and exclusive ecosystem access.
For Brazilian crypto influencers, community leaders, and power users, this creates a real income stream in SOL beyond personal spending alone.
Amulets vs. Other crypto card options for Brazilians
Binance Card (Brazil)
The Binance Card in Brazil is a Mastercard prepaid card with up to 2% cashback in BNB, capped at 250 BRL/month. It carries a 0.9% conversion fee and 1–2% FX fees on foreign transactions. It's a reasonable option for Binance power users already in the BNB ecosystem, but the monthly cap and BNB dependency limit its appeal for users focused on SOL accumulation.
KAST
KAST is Solana-first and globally available, with stablecoin funding via the Solana network. The free tier earns 1% in KastPoints, with higher rates available on paid tiers ($1,000–$10,000/year). However, KastPoints are tied to a future Token Generation Event (TGE), meaning a portion of your rewards is speculative until the $KAST token launches.
Traditional fintechs
Products like Nomad or international accounts from Brazilian fintechs offer dollar access but generally don't provide crypto rewards. They also operate within Brazil's banking regulatory framework, which means IOF may apply depending on how the account is structured and used.
Amulets
The clearest differentiator: real SOL rewards, no annual fees, no staking, no FX markup, and a referral program built for network growth. For Brazilian users who want dollar-stable spending power combined with automatic SOL accumulation, Amulets is the most direct product in the market.
Practical use cases for Brazilian Amulets users
International travel: Spend crypto wherever Visa is accepted, with no traditional banking markup and SOL rewards on every purchase.
Global subscriptions and software: Pay for services like AWS, Adobe, Notion, Netflix (US), or any dollar-denominated subscription and earn SOL automatically.
Freelancers and remote workers: Receive payment in stablecoins, keep value in USDC/USDT, and spend directly without converting to reais and back.
Crypto community builders: Share your referral link with your audience and earn passive SOL on every purchase your network makes, indefinitely.
