The exchange is bringing its simplified decentralized trading platform to a key market of 215 million people, even as its stock price faces headwinds amid a market downturn.

Coinbase is expanding the reach of its decentralized exchange (DEX) aggregator, dubbed "DeFi Mullet," to Brazil. The platform allows users to trade tens of thousands of tokens directly from the Coinbase app, abstracting the technical complexities typically associated with decentralized finance (DeFi).

Powered by Coinbase's Ethereum layer-2 network, Base, the "DeFi Mullet" service first launched in the U.S. in October. It enables users to trade on popular DEXs like Uniswap and Aerodrome without leaving the Coinbase interface. Users can trade without network fees by using a self-custody wallet, maintaining full control over their assets. Coinbase did not provide a specific launch date for the Brazilian rollout.

The expansion occurs as Brazil implements new banking-style regulations for the crypto sector, which classify stablecoin transactions and certain self-custody wallet transfers as foreign-exchange operations. The country, with a population of 215 million, is also moving to adopt the international Crypto-Asset Reporting Framework (CARF).

Part of a Broader "Everything App" Strategy

The DeFi Mullet initiative is a key component of Coinbase's strategy to become an "everything app," providing its over 100 million users with "24/7 access" to a wide range of financial services. This vision includes:

• Advancing stablecoin adoption, particularly Circle's USDC.
• Offering tokenized stocks and prediction markets.
• Facilitating early-stage token sales.

The company reported strong adoption of its Base network in Q3 across trading, payments, and social apps. It also highlighted the launch of "Flashblocks," a feature that enables 200-millisecond block times for faster transaction preconfirmations.

Further solidifying its commitment to the crypto economy, Coinbase expanded its corporate Bitcoin treasury, adding 2,772 BTC in Q3 to bring its total holdings to 14,548 BTC, worth approximately $1.3 billion at current prices.

Strong Earnings Contrast with Stock Performance

This strategic expansion is backed by robust financials. Coinbase reported a more than fivefold year-over-year increase in net income for the third quarter, reaching $432.6 million. Total revenue surged 55% to $1.9 billion.

Despite this strong performance, Coinbase's stock (COIN) has not been immune to the recent market correction. Shares are down 25.2% over the past month, trading at around $257.29. This has erased its gains for the year, with COIN now trading nearly flat since the start of 2025, mirroring declines seen in other crypto stocks like MARA and STRAT.
