UD Blockchain

UD Blockchain is a Hong Kong enterprise blockchain provider whose work runs from underlying infrastructure to delivered applications. On the infrastructure side it offers blockchain-as-a-service for public, private and consortium chains, plus validator and RPC node hosting in Tier III or higher data centres, covering Ethereum, Polygon, BNB Chain, Solana, Cosmos, Cardano and Avalanche among major networks, and consortium frameworks such as Hyperledger Fabric.

On the application side it covers smart-contract development and auditing, asset tokenisation, NFT marketplace builds, a crypto payment gateway and over-the-counter exchange. Audits are handled in-house across code review, logic-flaw analysis and penetration testing; the payment gateway accepts both crypto and Visa or Mastercard and reconciles them in one back office. Clients are mainly Hong Kong retail, catering and brand businesses, with public work including NFT projects for TamJai and McLaren.
