Blockchain Wallet: The Passport to the Web3 World

Blockchain wallets are the gateway and pass for users to enter the Web3 world. Its main functions include creating Blockchain accounts, managing Blockchain assets, exploring the Blockchain ecosystem, and conducting transactions. Similar to traditional banking apps, users can view their asset status and perform operations such as transfers through the wallet.

Compared to traditional payment tools, blockchain wallets have characteristics such as decentralization and anonymity. The assets managed by it belong directly to the user, rather than to a centralized institution's accounting. However, the management of the wallet's private keys also poses challenges for users.

To solve the issue of private key management and enhance user experience, smart contract wallets have become a mainstream solution. It is a type of contract account that behaves like a Wallet, allowing asset management and interaction with DApps without the need for private keys. Multi-signature wallets are a form of smart contract wallets that require multiple key signatures to execute transactions.

Account abstraction is an important concept for further improving wallets. It allows the separation of transaction validation and execution into customizable modules, enabling smart contracts to act as transaction initiating accounts. Proposals like ERC-4337 provide solutions for implementing account abstraction.

In the future, Wallets are expected to become an important entry point and infrastructure for Web3. They will integrate various DApps and become a hub for users to engage in social interactions, shopping, and other activities in the blockchain world. Blockchain wallets are evolving towards becoming the "Alipay" of the Web3 world.
