Vitalik Buterin urges Web3 wallets to improve security, privacy

Published

on

Ethereum co-founder Vitalik Buterin has called for significant improvements in the security and privacy features of Web3 wallets, emphasizing their critical role in fostering wider adoption of decentralized technologies. Speaking at a developer event on Nov. 21, Buterin highlighted the challenges users face with current wallet solutions, including susceptibility to hacks and a lack of user-friendly designs.

Buterin outlined several proposals to address these issues, including integrating advanced cryptographic techniques, such as multi-signature functionality and social recovery mechanisms. He stressed that improving wallet security must go hand-in-hand with protecting user privacy, noting the risks posed by data leaks and surveillance in decentralized ecosystems. These enhancements, he argued, are essential for mainstream users to trust and embrace Web3 platforms.

The Ethereum co-founder also encouraged developers to focus on accessibility, ensuring wallets are intuitive for users with minimal technical knowledge. He pointed to the rise of mobile-based wallets as a promising trend but cautioned that usability should not compromise security. Buterin believes a collaborative effort between blockchain developers and wallet providers is necessary to set new industry standards.

With Web3 adoption accelerating across industries, Buterin’s remarks underline the urgency of addressing these foundational challenges. As decentralized applications continue to gain traction, robust and user-friendly wallet solutions will play a pivotal role in determining the ecosystem’s long-term success. His advocacy for innovation in this space reflects the broader push to make blockchain technology accessible and secure for a global audience.

Brave adds Cardano blockchain support to browser and Web3 wallet

Published

on

Brave, the privacy-centric web browser, has announced the integration of the Cardano blockchain into its native and standalone wallets. This development enables users to directly access Cardano’s assets and participate in its governance features without leaving the Brave interface.

The integration results from a partnership between Brave and Input Output (IO), the development firm behind Cardano. According to Brendan Eich, co-founder and CEO of Brave, this move not only expands multi-chain access but also enhances security, governance participation, and the overall user experience.

Users can now manage ADA and other Cardano-native tokens, execute swaps, and engage in on-chain governance directly through the Brave Wallet. This addition complements Brave’s existing support for Ethereum and Solana, furthering its commitment to providing a comprehensive multi-chain experience.

Robert Roose, founder of Cardano interoperability protocol Mynth, commented that this integration is a significant step toward making Cardano more widespread and interoperable. He noted that most of the necessary infrastructure and tooling are already in place, positioning Cardano for broader adoption.

The partnership also sets the stage for future innovations, particularly concerning Midnight, a privacy-focused Cardano sidechain developed by Shielded Technologies, an IO spinout. Midnight aims to facilitate confidential smart contracts and data protection, with potential applications including free transactions for NFT ticket holders.

This collaboration marks the beginning of a long-term partnership between Brave and IO, with plans to further integrate Cardano’s governance features and expand the functionalities of the Brave Wallet.

Dubai’s Department of Finance (DOF) has entered into a strategic partnership with Crypto.com to facilitate cryptocurrency payments for government services. The agreement, announced during the Dubai Fintech Summit on May 12, aligns with the emirate’s ambition to become a fully digital, cashless society by 2026.

Under this initiative, individuals and businesses will be able to pay for government services using cryptocurrencies via Crypto.com’s digital wallets. These crypto payments will be converted into United Arab Emirates dirhams and transferred to the DOF’s accounts, ensuring seamless integration with existing financial systems.

Amna Mohammed Lootah, Director of Digital Payment Systems Regulation at the DOF, emphasized the significance of this development, stating that it would substantially accelerate the advancement of Dubai’s Cashless Strategy. The DOF has indicated that the service will accept “stable cryptocurrencies,” suggesting that stablecoins pegged to fiat currencies may be utilized, although specific digital assets have not been disclosed.

This move is part of Dubai’s broader strategy to enhance its fintech sector and stimulate economic growth. The DOF projects that the cashless initiative could contribute at least 8 billion dirhams (approximately $2.1 billion) to the economy by fostering the development of financial technology services.

Ahmad Ali Meftah, Executive Director of the Central Accounts Sector at the DOF, noted that the government is actively developing a regulatory framework that promotes innovation while ensuring the highest standards of security and efficiency in digital financial transactions.

Dubai’s progressive approach to digital assets is further evidenced by its recent initiatives, including the pilot phase of a project to tokenize real estate assets on the blockchain and the hosting of the Token2049 conference, which underscores the city’s commitment to embracing emerging technologies.

The collaboration with Crypto.com marks a significant step in Dubai’s journey toward integrating cryptocurrency into its public services, reflecting the emirate’s position as a forward-thinking leader in digital finance.
