Assistive Technology Support
HiYesNo actively tests and optimizes platform compatibility with mainstream assistive technologies to ensure users with disabilities can effectively use our services.
Tested Assistive Technologies
- Screen readers: NVDA (Windows), VoiceOver (macOS/iOS), TalkBack (Android)
- Keyboard navigation: full site Tab-key navigation, all critical actions completable via keyboard
- High contrast mode: compatible with native OS high-contrast themes
- Text scaling: supports browser 200% font scaling without breaking page layout
Known Limitations
Web3 wallet interactions (such as MetaMask popups) are controlled by third parties; their accessibility is the responsibility of each wallet application. We recommend using wallet apps that support assistive technologies.
Continuous Improvement
Our development team continuously monitors new assistive technology versions and best practices, regularly updating the platform to maintain compatibility. Please let us know immediately if you discover compatibility issues.
