Fanlivecards

Context

Supported by renowned investors, Sponsorlive entrusted us with the mission of creating the first NFT platform dedicated to rugby: FanLiveCards. It consists of NFTs of the most recognized rugby players and coaches divided into several card categories: Gold, silver, black, platinum.

Metastudio

Context

Metastudio is a metaverse for entrepreneurs and influencers active on social networks. This new model will allow content owners to sell their creations and get rewarded with a token after each sale. They entrusted us with the development of their METAS token deployed on Polygon as well as the implementation of a Blockchain architecture for the metavers.

CodeNekt

Context

CodeNekt is a mobile application for the administrative management and technical monitoring of vehicles. The initial idea was to make life easier for the owner by allowing them to have all the information related to their vehicle in a single application. No more lost invoices, no more forgotten technical deadlines.

YouSov

Context

YouSov is a decentralized application, meaning it does not require a trusted third party to operate. The purpose of the YouSov application is to provide a solution for recovering important information, called a Secret, to a user without needing an identifier/password pair and regardless of their location. The user will need to answer personal questions they have pre-recorded, and the answers will then be validated by agents.

Push By Panelys

Context

Push by Panelys is a payment solution aimed at facilitating the financial inclusion of the rural population. The application allows the creation of an account linked to a physical or digital VISA card directly associated with the user’s mobile device, thereby providing access to all major digital financial services.

Bolero Music

Context

Bolero Music is a platform that allows you to invest in the music rights of your favorite tracks and earn royalties. Bolero’s goal is to democratize music investment in order to generate new revenue for creators while preserving their creative control.

EDF

Context

The client EDF R&D asked us to build their intranet talent platform. This platform called “Talent” allows EDF (R&D) employees to propose, choose and vote for Hackaton projects that would receive a budget to be realized. All the budget balances of employees, projects and campaigns are managed by an ERC20 token on the private blockchain “Parity”. Thus, the platform presents a kind of decentralized organization internally, based on a smart governance contract.
