KEKKAI

KEKKAI is a Web3 security company established in early 2023 with a vision to create a trusted environment for all users. The company, headquartered in Tokyo, Japan, provides security solutions for both individual and business clients.

The firm's core offerings include the KEKKAI Plugin, a browser extension, and the KEKKAI Mobile app. These products protect users by simulating blockchain transactions before execution. This process allows the detection of potential risks like phishing scams, honeypots, and malicious smart contracts, issuing warnings to the user to prevent asset loss. The tools support over 100 blockchains and are compatible with major wallets like MetaMask and Trust Wallet.

For corporate clients, the company offers enterprise solutions through KEKKAI Labs. This includes KEKKAI Audit, a service that reviews smart contracts and decentralized applications (DApps) for vulnerabilities before they are deployed. They also provide their fraud detection capabilities through an API and SDK for integration into other platforms, as well as penetration testing services. In October 2024, KEKKAI announced a rebranding to Alpha Network, shifting focus to build a decentralized AI data execution layer to address the shortage of AI training data while leveraging its Web3 security infrastructure.

The company was founded by Duma, who also serves as CEO. KEKKAI has secured significant funding, including a pre-seed round of JPY 50 million in February 2023 and a seed round of approximately $1.5 million (JPY 230 million) in January 2024 from investors such as Decima Fund and Bixin Ventures.
