I came to Japan in 2018, founded Unisma Co., Ltd. during my first year at university, and was developing SNS apps and contract development for university students as my main business. After experiencing the NFT incubation business and smart contract No Code tool products in-house in 2022, we developed Kekkai and established a new company based on the Web3 security business. We provide KEKKAI, a tool to prevent Web3 phishing scams, and KekkAI SDK services that can detect fraud, etc.
