What is a certificate NFT that cannot be resold or transferred?
Unlike ordinary NFTs, certificate NFTs offered by HEXA are issued in a form that cannot be traded on the secondary market or transferred.
This mechanism ensures reliability as "proof that the person themselves definitely holds it," so it can be used to prove identity, participation or accreditation in the digital world.
Example use: proof of event participation
For example, if you give every participant at an event a "certificate of participation NFT,"
you can run online communities and follow-up activities after the event that only users holding that NFT can join.
Because only the person themselves can hold the NFT, event organizers can reliably identify participants and build ongoing relationships with them (such as forming a fan community or announcing the next event).
How it works
Issue "certificate of participation NFTs" to event participants
Participants receive their own certificate NFT
After the event, they join holder-only communities and follow-up activities
→ Because it cannot be resold or transferred, you can reliably maintain an ongoing relationship with the actual participant
Other uses
Educational institutions and online courses: certificate of completion NFTs, certificate of attendance NFTs
Corporate training and internal awards: proof of in-house qualifications, award commemorations
Government and community organizations: proof of local volunteer participation, proof of digital residency
Fan clubs and brand memberships: use as genuine proof of membership
In every case, the key feature is that the NFT delivers both "proof" and "connection."
About HEXA
HEXA is one of Japan's largest NFT marketplaces, offering a simple system that requires no crypto-assets and supports payment in Japanese yen.
We provide an environment where NFTs can be used not as "speculative products" but as "practical digital tools,"
and are building an ecosystem where a wide range of issuers, including artists, companies and municipalities, can use NFTs with peace of mind.
What's next
Going forward, we will further expand participant-only community features and ongoing follow-up systems that use this certificate NFT function,
and aim to promote its use in education, events, government and business as "NFTs that keep connections going."
