Coinbase has introduced decentralized exchange (DEX) trading in Brazil, marking a significant expansion of its 'everything app' strategy. The new 'DeFi Mullet' feature enables Brazilian users to access over 10,000 tokens through platforms like Uniswap, allowing for self-custody wallet management without network fees. This launch aligns with Brazil's evolving regulatory landscape, as the central bank prepares to enforce stricter regulations on crypto firms, including licensing, international transaction reporting, and capital requirements up to $7 million, effective mid-2025.
