Card3

Card3.ai is a Web3-centric social network with AI tools that aims to make it easier to create and verify professional connections. Using AI, the platform helps participants find relevant partners, build trust and reputation based on offline and online activity.

The platform actively integrates with NFC tokens - physical objects (“phygitals”). The device records meeting information through scanning, helping to securely record IRL meetings with TokenProof.

Card3.ai was demonstrated at the Hong Kong Web3 Festival 2025, where they clarified how AI helps improve networking by automating recommendations and connection analysis.

The platform also provides a layer that connects blockchain, social media and offline activities, creating an end-to-end digital reputation - “ProofofConnection”. This is a new interaction format that can change the approach to networking in Web3.

Card3.ai aims to make social connections and authenticity measurable and trustworthy in Web3, using a combination of AI, physical interaction, and decentralized data recording. This gives the web a new format of professional ecosystem for creators, investors, and real-world participants.
