What KEKKAI does

KEKKAI is a Tokyo-based Web3 security company founded in 2023 that provides wallet protection and smart contract security services. Its product portfolio centers on the KEKKAI Plugin and mobile app, which detect and allow users to revoke dangerous wallet signatures, supplemented by a Dashboard for permission management and Alpha Network, an AI-augmented threat detection layer. Through KEKKAI Labs, the company sells enterprise services including smart contract and DApp audits, penetration testing, and API/SDK-based wallet security integration, targeting Web3 projects, DApps, and enterprise wallet builders.

The company operates a hybrid revenue model combining professional services (project-based security audits and penetration testing) with subscription/recurring revenue from enterprise security solutions and consumer products. Distribution runs through direct enterprise sales via KEKKAI Labs, self-serve consumer products (plugin, mobile app, dashboard), and embedded API/SDK integration. The company cultivated a registered community of white hackers and the KEKKAI University educational platform to build credibility in the Japanese Web3 market.

KEKKAI raised approximately JPY 50 million in pre-seed funding in February 2023 and roughly JPY 230 million in seed funding in January 2024 from investors including Decima Fund, Bixin Ventures, Sora Ventures, and a broader syndicate. In January 2026, the company was acquired by BitsLab and rebranded as BitsLab Safe, integrating its front-end wallet protection capability with BitsLab's back-end audit portfolio across Move, BSC, Ethereum, Solana, and TON ecosystems.
