  Web3 is leading a wave of the next generation of web services that even many
Web2 applications are keen to ride. However, the lack of Web3 background for
Web2 developers hinders easy and effective access and transition. On the other
hand, Web3 applications desire for encouragement and advertisement from
conventional Web2 companies and projects due to their low market shares. In
this paper, we propose a seamless transition framework that transits Web2 to
Web3, named WebttCom, after exploring the connotation of Web3 and the key
differences between Web2 and Web3 applications. We also provide a full-stack
implementation as a use case to support the proposed framework, followed by
interviews with five participants that show four positive and one natural
response. We confirm that the proposed framework WebttCom addresses the defined
research question, and the implementation well satisfies the framework WebttCom
in terms of strong necessity, usability, and completeness based on the
interview results.
