Why did we start MCH +?


double CEO / CTO Hironobu Ueno

The concept of “NFT (Non-Fungible Token)” was born by the practical application of the smart contract standard “ERC-721”, which was mainly used for unique digital assets on the Ethereum blockchain.
With NFTs, digital items will shift from “digital commodities“ to “digital assets“, that have unique characteristics, verifiable histories, and provable supply. In a future where real and digital worlds are increasingly intersecting, NFT assets will hold real value similar to physical assets today.

Double's first blockchain game ”My Crypto Heroes” was built with the vision ”Time, money and passion for the game will become your assets (= NFT)”. The innovation of this game is the game ecosystem, centered around NFT asset value creation.
Unlike conventional digital items that are stored on servers, NFTs are stored on the blockchain and give users real ownership over their items. NFTs are stored in the users' wallets, where they can manage assets freely by buying, selling, gifting, or even importing their assets into another game.
This is the open “NFT ecosystem”, which is creating a brand new UX for users. To enable this whole new gaming experience, we are providing mechanisms to game developers to create NFTs that can be used across various game apps within the MCH + universe.

Based on our experience of developing and operating the #1 Blockchain Game My Crypto Heroes, we will provide game developers with 4 verticals: “NFT Economics Design, “Game Ecosystem Design, “Financial Support”, and “Training HR Support” for the development of this brand new industry

We will teach and apply all of our learnings from building ”My Crypto Heroes”.

”My Crypto Heroes” is the number one Blockchaing Game in the world in terms of Daily Active Users and NFT transaction volume. The development support program ”MCH + (MCH plus)” was started by the My Crypto Heroes team to spread the learnings.

By using the “MCH +” framework, a full-scale blockchain game can be quickly developed, even without the know-how of developing a blockchain game.

In addition to the development support, we connect our MCH + partners through cross-game assets, like turning your character into a My Crypto Heroes item and vice versa.
