Why we start MCH+?


double CEO / CTO Hironobu Ueno

The concept of “NFT (Non-Fungible Token)” was born by the practical application of the standard “ERC-721” , which was mainly used for managing digital assets on the Ethereum blockchain.
With NFT, digital items will shift from “digital commodities“ that can be copied as before to “digital assets“ with different meanings and different histories. And in the future, NFT assets will keep the certain amount of value in the world where real and digital are increasingly mixed.


double CEO / CTO Hironobu Ueno

The blockchain game represented by our ”My Crypto Heroes” was exactly the world where ”Time, money and passion for the game will become your assets (= NFT)”, by designing an ecosystem centered on NFT.
Unlike conventional digital items on servers, NFT guarantees ownership through blockchain, and it can jump out of the world of one game app. NFT can be displayed on different apps such as Wallet, users can transfer that freely through buying, selling, gifting.
This is the “NFT ecosystem”, which is creating a brand new UX for users.In order to make this UX even more valuable, we will provide a mechanism that allows NFT to be used across various game apps as MCH+.
NFT is a unique and valuable digital asset, so it will be handed down among users.
For the sustainable development of the NFT ecosystem, “MCH +” will provide a mechanism that the benefit will distribute to content creators according to the secondary distribution value.
Based on the know-how of the development and operation of NFT games obtained at MCH, we will provide mainly these 4 things as follow, “NFT game designing“, “ecosystem designing”, “financial support”, and “human resource development support” for the development of this brad new industry

We will provide development support program by using the knowledge that we learned through developing ”My Crypto Heroes”,
which keeps running top in the world in terms of Daily Active Users, and transactions.

”My Crypto Heroes” is the number one in the world in terms of Daily Active User, NFT transaction volume. The development support program ”MCH + (MCH plus)” has been newly provided from the My Crypto Heroes.

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

In addition to the development support, we aim to expand the blockchain game ecosystem by using game assets MCH+ partners' games such as My crypto Heroes.
