PassiveBolt is a decentralized identity platform that provides Web3-based access control solutions for physical spaces. The company operates as a Tier1 supplier to lock manufacturers and access control companies, providing hardware and software components that enable cryptographic authentication for unlocking secure spaces. The platform utilizes blockchain registry for universally unique identifiers and cryptographic attestations to authorize access based on individual identity rather than physical objects like cards or secrets like PIN codes. This approach integrates Web3 identity wallets with physical access control systems. PassiveBolt's product portfolio includes hardware components such as Web3-capable locks, readers, and control panels that support both cryptographic and traditional credentials. The company has developed proprietary mechatronic technology featuring gearless direct actuation for locks, designed for energy efficiency and compact form factor. Their solutions also incorporate sensors with algorithms for door tracking, micro location, and touch detection. The company targets multiple market segments including hotels and car rental services, where they enable automated check-in processes and mobile key delivery. Their Tier1 supplier model allows lock manufacturers and access control partners to deploy solutions with reduced R&D costs and faster time to market. PassiveBolt provides connectivity modules supporting various protocols and develops decentralized applications (dApps) and decentralized web applications (DWA) to complement their hardware offerings.
