Vitalik Buterin, co-founder of Ethereum, makes an appeal to Web3 developers to improve privacy and security in digital wallets. Among the proposals, solutions to simplify transfers between layer-2 networks and integration of advanced features.
Let’s see all the details in this article.
Innovations in web3 wallets: proposals to improve privacy and security
Vitalik Buterin, one of the most influential figures in the world of cryptocurrencies, continues to shape the future of blockchain technology with innovative proposals.
In a post from December 3, the co-founder of Ethereum urged Web3 wallet developers to focus on two fundamental aspects: improving user privacy and strengthening the security of digital wallets.
According to Buterin, wallets are not simple storage tools, but represent the bridge between the user and the functionalities offered by the blockchain:
“A user can benefit from the decentralization, censorship resistance, security, and privacy of Ethereum only if the wallet itself possesses these qualities.”
Buterin has criticized the reliance on specialized wallets for managing private transactions. Currently, making private transfers on Ethereum requires the use of wallets dedicated to privacy, which represents a significant barrier for many users.
His proposal therefore aims to revolutionize this approach. Instead of relegating privacy to a niche, it suggests integrating privacy features directly into standard wallets.
A method could consist of maintaining a portion of the users’ assets as a “private balance” in a privacy pool, usable for executing anonymous transactions.
This idea finds fertile ground following the recent decision of a US court, which determined that the Department of the Treasury exceeded in sanctioning Tornado Cash, a privacy protocol.
This verdict could pave the way for greater development of on-chain features dedicated to privacy.
Security: the importance of multisignature authorization
Regarding security, Buterin recommends the widespread adoption of multisignature authorization in Web3 wallets.
This system, in which multiple signatories must approve a transaction before it is completed, adds an additional layer of protection against potential attacks or unauthorized access.
“The implementation of multifirma in wallets should not be an option, but a standard,”
he emphasized. This approach would guarantee greater peace of mind for users and would increase trust in the system.
Another crucial topic addressed by Buterin concerns the transfers between Ethereum layer-2 (L2) networks, such as Optimism and Arbitrum.
These scalability solutions, designed to enhance the performance of the main network, currently manage over 50 billion dollars in total value locked (TVL).
Buterin has proposed introducing a function in wallets that allows users to send tokens directly to another wallet on a different L2 network, eliminating the need for complex processes.
For example, it suggests adopting addresses that include a suffix indicative of the network, such as @optimism.eth.
With this feature, a user could simply paste such an address into the “recipient” field of a wallet and send the tokens. The wallet would automatically process the transfer, simplifying the user experience significantly.
The push for greater decentralization
Buterin’s proposals are consistent with his goal of accelerating the decentralization of layer-2 networks.
Since last September, he stated that he wants to publicly recognize only the networks that reach a certain level of autonomy, with active fraud or validity proof schemes.
According to his plan, by 2025 only the solutions that meet these criteria will be mentioned, thus encouraging developers to continuously improve their systems.
In other words, Vitalik Buterin’s observations highlight how Web3 wallets must evolve to adapt to the growing needs of users.
Privacy and security can no longer be considered extra options, but must become an integral part of the user experience.
Furthermore, the innovations proposed for cross-layer-2 transfers could revolutionize the interaction with the blockchain, making Ethereum and its scalability networks even more accessible.
