OIO Holdings Limited is a Singapore-based investment holding company that provides blockchain technology solutions, digital asset staking services, and mechanical and electrical engineering consultancy. Founded in 2017 and headquartered in Singapore, the company operates primarily across Singapore and the broader Asia-Pacific region, serving institutional clients, corporate enterprises, digital asset holders, and infrastructure development contractors.
The company operates through two core business segments: Blockchain Technology and Mechanical & Electrical Engineering Services. Its primary products and services include proof-of-stake (PoS) staking pool validation and staking infrastructure through the Moonstake platform; non-custodial multi-asset digital wallet solutions supporting cross-chain asset management; enterprise blockchain consulting, customized smart contract development, decentralized application (dApp) architecture, and distributed ledger integration; digital asset ecosystem support services for Web3 developers and institutional staking participants; turnkey mechanical and electrical (M&E) engineering contracting; project management, installation, testing, and commissioning of electrical, sanitary, plumbing, and fire protection systems; and engineering manpower provisioning and procurement advisory.
In recent developments, the company executed a strategic transformation, formerly operating as DLF Holdings Limited before rebranding to OIO Holdings Limited to signal its expansion from traditional engineering into Web3 and financial technology infrastructure. Following its acquisition and integration of the Moonstake staking ecosystem, OIO Holdings has focused on scaling its B2B staking validation operations, expanding protocol support for leading proof-of-stake networks, and developing enterprise-grade staking-as-a-service (SaaS) APIs. Concurrently, the group has restructured its legacy engineering and project management operations to optimize capital allocation toward digital asset services and Web3 advisory, while strengthening compliance and governance frameworks in alignment with evolving digital asset regulations under the Monetary Authority of Singapore.
