Recently, I often hear questions in the community: seeing a project's official website UI design that looks outstanding, taking a screenshot directly as an illustration for my own article; discovering some open-source code that is very useful, copying and pasting it into a commercial project. These actions seem harmless, but in the Web3 world, all ownership and usage rights issues are much more complex than most people imagine.

Take a well-known oracle project as an example. Visiting its official website, browsing its documentation, studying its branding materials—these actions themselves are not problematic. But that doesn't mean these assets become public property. The rules are straightforward: you can look, you can learn, but you cannot use them to make money or claim ownership without authorization.

Why should this matter? There are three details worth clarifying:

**Brand assets are not a self-service素材库**
Logos, visual systems, project names—these are brand assets carefully crafted by the project team and are legally protected. Using them for personal learning or non-commercial discussion is acceptable (for example, citing sources in analytical articles), which is usually fine. But printing merchandise to sell or using them to endorse your own project crosses the line. The community's tolerance for such behavior is very low and will be directly regarded as unprofessional.

**The boundaries of open-source code are not so black and white**
Many projects open-source some code to promote the ecosystem. But "open source" and "arbitrary commercial use" are completely different. The type of license determines what you can and cannot do. Some licenses restrict commercial use, some require attribution. Using code directly without paying attention to these details is like setting a landmine.

Understanding these boundaries is not only about protecting your legal awareness but also a basic quality for establishing yourself in the Web3 community.
