This week’s top crypto headlines in LATAM highlight a region juggling innovation and regulation, ranging from El Salvador’s blockchain-backed public records to Brazil’s cautious approach to Bitcoin treasuries and the growing momentum of DeFi adoption.

El Salvador uses Bitcoin to secure official documents

El Salvador has begun to utilise Bitcoin technology to maintain official digital records, marking a new era in government transparency.

The initiative, sponsored by the National Bitcoin Office (ONBTC) in partnership with the United States-based startup Simple Proof, uses the OpenTimestamps protocol to assure authenticity and permanence on the Bitcoin network.

This enables any registered document to be verified on the blockchain using its timestamp, resulting in an immutable public record that cannot be changed or falsified.

According to Simple Proof CEO Carlos Toriello, the technology does not save personal information or complete files on the blockchain.

Instead, it creates a cryptographic hash, a unique digital fingerprint, for each page.

This allows you to certify millions of data points with a single transaction while maintaining privacy and network efficiency.

The first formal implementation occurred with the CUBO+ program’s graduation certificates, which are all verifiable via Bitcoin’s blockchain.

Brazil’s Bitcoin Treasuries face regulatory uncertainty

Brazil’s largest Bitcoin treasuries, such as OranjeBTC and Méliuz, face an uncertain regulatory picture as Asia tightens regulations.

While Hong Kong and India have prohibited Bitcoin treasury listings, Brazil takes a more open approach centred on investor education and transparency.

Analysts believe that the country’s regulatory structure will not impose drastic limits, but regulators will continue to monitor listed corporations that serve as indirect Bitcoin investment vehicles.

Experts point out that Brazil’s crypto landscape is more adaptable because of existing instruments such as Bitcoin ETFs and COEs, which already provide exposure to digital assets.

This lessens the requirement for treasury-style organisations to have Bitcoin as their primary asset. Nonetheless, the concept piques regulatory interest, as these firms lack typical operations and blur the border between innovation and monitoring.

The future of Bitcoin treasuries in Brazil will be determined by their ability to preserve transparency and investor safety in the face of shifting global trends.

Bitget Wallet’s Stablecoin boom reflects DeFi’s push for stability

Bitget Wallet’s total value locked (TVL) in stablecoin yield products increased 523% in the third quarter of 2025, topping $80 million, as investors sought transparent and safe on-chain income.

The growth reflects a dramatic shift in DeFi, with consumers preferring self-custodial choices over centralised services.

The growing acceptance of stablecoins in Europe and Asia demonstrates how they are becoming crucial tools for savings and cross-border transactions, bridging traditional and decentralised finance.

This increasing momentum follows the success of Bitget’s Stablecoin Earn Plus, a USDC-based product on Aave that provides a fixed 10% yearly return with real-time accruals.

Bitget Wallet wants to make DeFi earnings as easy to understand as traditional savings by streamlining yield generation.

The company’s emphasis on autonomy, openness, and accessibility reflects the global trend toward self-custody and provable, long-term crypto revenue.
