Wakame
A Holdex-built Proof of Attendance Protocol for events
Table of Contents
Wakame is Holdex's bet on what an event-attendance NFT should look like. A Proof of Attendance Protocol where the proof is real, the experience is friendly to people who haven't touched a wallet, and the organiser controls who gets the collectible without trusting attendees to behave. The web product runs at wakame.app and was built end-to-end by Holdex.
Our work covers product co-building and smart contracts. Wakame is Holdex's project. There's no separate company behind it.
What it does
The technical stack is straightforward. NFT tokens, event metadata, and smart contracts handle minting, transfers, and resale. The interesting part is the issuance flow.
The hero feature is Collect by Code. Organisers generate unique six-digit codes (extended in the mobile app to QR scanning at the venue) so only actual attendees can claim the NFT. Limited supplies enforce scarcity at the door, not on the blockchain afterward. That solves the authenticity problem most POAP-style protocols don't. The people walking in get the token. The people who didn't show up don't.
The product design deliberately targets event organisers and attendees who haven't worked with blockchain before. Wallet onboarding is hidden inside the app flow. The collectible appears as a simple object in a personal collection, with the on-chain mechanics invisible by default.
The story
Wakame is one of Holdex's quieter internal builds. The useful story is the product decision: make attendance proof harder to fake, hide wallet complexity from attendees, and give organisers a simple issuance path that works at the door.
