Web3 infrastructure is taking shape, with five categories of tools and applications leading the future.

The complete realization of the Web3 vision still requires time, but some foundational tools have already begun to play a role. For example, on-chain communication, Web3 email, treasury management, document signing, and data indexing applications are laying the groundwork for Web3. These tools embody several key characteristics of Web3: permissionless access, authenticity, data portability, efficiency, and the "dark forest."

It is worth noting that Web3 will not be completely separate from Web2, but will gradually penetrate and improve upon Web2. Currently, more than 30 Web3 tool applications have been put into use, let's take a look at some of the representative projects among them:

In terms of on-chain communication, Push Protocol and XMTP are two projects that have received significant funding. They enable bidirectional communication between wallet addresses and allow DAPPs to send notifications to users. However, these types of applications still face issues such as spam proliferation.

Web3 email services such as Skiff and Mailchain support logging in with wallet addresses and offer encryption and other privacy protection features. However, they need to enhance integration with DAPPs to improve adoption.

In the treasury management tools, Safe(, the original Gnosis Safe), dominates the market. These tools generally support multi-signature management, payment functions, and data analysis features, serving both DAOs and attracting traditional institutions.

Web3 document signing tools such as ETHSign use wallet addresses for signing, effectively preventing signature forgery.

On-chain data indexing tools such as RSS3 and neeva.xyz aim to simplify the search and analysis of on-chain data, providing users with more readable semantic tools.

These applications demonstrate some common features of Web3: permissionless access, data authenticity, efficient liquidity, and so on. They are laying the foundation for the widespread application of Web3, which may bring more innovative business models and workflows in the future.
