Purpose of the Event

KEKKAI is a company that specializes in Web3 security products. We are planning to host the "KEKKAI CryptoSec Conference" as a side event of TEAMZ WEB3 SUMMIT 2023. Our goal is to offer participants an opportunity to expand their knowledge in the field of encryption security and foster networking among professionals in the Web3 industry.

At this year's EthGlobal Tokyo, TEAMZ Web3 Summit, and various side events, many Web3 professionals gained new experiences and achieved growth. Distinguished foreign experts in the Web3 industry visited Japan and brought new opportunities and inspiration to the Japanese Web3 industry in terms of technology applications, market demands, resource sharing, and more.

Our networking event and "KEKKAI ZONE" held in April received excellent feedback. Therefore, we have decided to hold the "KEKKAI CryptoSec Conference" to share knowledge on encryption security and provide opportunities for industry professionals to form new collaborations.

We are a Tokyo-based web3 protocol that provides a wide array of on-chain security solutions and services. The total amount of crypto frauds in 2022 is estimated to be 490 billion yen, which is about three times the amount of the previous year, and is a major challenge for the industry.

In order to overcome this situation, KEKKAI is committed to providing a more secure experience to the industry as a whole and contributing to the improvement of the environment. Currently, we have released KEKKAI, a Web3 security plugin that enables risk detection through transaction simulation analysis, and an API service that enables NFT fraud detection and transaction simulation.

In the future, we plan to improve our current services and release products and services to improve user security from various angles.
