The distributed digital protocol based on blockchain technology is accelerating movement towards the ageof Web 3.0 in the world and driving investments in start-ups seen to be leading this new age with crypto asset
and Non-Fungible Tokens (NFTs). In Japan, however, unclear accounting rules and laws in the realm ofcrypto asset and NFT, coupled with a lack of expert insights, hinders entrepreneurship in this area, resulting
in a lower number of start-ups compared to overseas. To address this challenge, the company is stepping into support start-ups in the crypto asset and NFT fields who have potential to lead the Web 3.0 age. ThroughCoincheck Labs, the company shares its experiences and expertise gained through the process of developing
and operating its cryptocurrency transaction services, Coincheck, as well as its NFT marketplace, Coincheck
NFT (β version).
Some of the applications in recent years, for example, DeFi which came to the forefront in 2020, and NFT,
which grew rapidly in 2021, presuppose crypto asset as a natural protocol to transfer values, thus creating thenew digital economy. At this turning point, the company wishes to contribute to the crypto asset and NFT
areas in Japan, working with peers who are committed to taking on the challenge together.
