Oobit, a payments firm backed by Tether, has integrated its services with Brazil’s PIX network, allowing nearly 170 million users to access and use the dollar-pegged stablecoin USDT for everyday transactions. The integration enables users to deposit Brazilian reais into the app, convert them into USDT, and make instant payments through PIX while still transacting in local currency.
The process mirrors standard PIX usage. Payments can be made by scanning QR codes or using PIX keys, while currency conversion between reais and USDT happens automatically in the background. USDT, issued by Tether, remains the largest stablecoin by circulation and now operates داخل one of the world’s most widely used real-time payment ecosystems.
Expansion backed by fresh funding
The rollout follows Oobit’s $25 million Series A funding round in 2024, led by Tether and Solana co-founder Anatoly Yakovenko. The funding has supported the development of tap-to-pay features and regional expansion, particularly in markets with high mobile payment adoption.
Pix growth supports stablecoin integration
Launched by Brazil’s Central Bank in 2020, PIX has rapidly scaled into a dominant payments infrastructure, processing billions of transactions monthly and reaching nearly the entire adult population. Its ease of use has made it central to both formal and informal economic activity, creating fertile ground for stablecoin-based payment solutions.
Other platforms have pursued similar strategies. In 2023, Nubank partnered with Circle to introduce USDC holdings to its users, signaling growing demand for digital dollar access in Latin America’s largest economy.
Regulation reshapes stablecoin payment models
Despite the momentum, Brazil’s regulatory stance is shifting. In April 2026, the Central Bank introduced Resolution BCB No. 561, which restricts how stablecoins can be used in cross-border payments. Starting in October 2026, electronic foreign exchange providers will no longer be allowed to use digital assets like USDT to settle the international leg of transactions.
The rule does not prevent individuals from holding or trading stablecoins. However, it limits how fintech firms can integrate them into cross-border services, forcing platforms to rely on traditional foreign exchange systems or regulated account structures.
Industry faces strategic adjustment
The new framework pushes companies to adapt. Firms may need to secure licensing as virtual asset service providers under stricter rules or redesign their operations to comply with Brazil’s foreign exchange system. This marks a shift away from stablecoins as a backend settlement layer for international transfers.
While PIX continues to expand with features like recurring payments and regional connectivity, the role of stablecoins within the system is being more tightly defined. For traders and fintech platforms alike, the focus is now on how to operate within these regulatory boundaries while maintaining the efficiency that drove early adoption.
