USDX was a stablecoin pegged 1:1 to the US dollar and developed by Lighthouse Blockchain Technology GmbH, based in Frankfurt, Germany. Launched in 2017, it was designed to maintain price stability via overcollateralisation using LHT, the native token of the Lighthouse Blockchain. USDX operated on a proprietary blockchain built on the BitShares protocol and used Delegated Proof of Stake (DPoS) as its consensus mechanism. A smart contract managed issuance and enforced a minimum 200% collateral ratio. USDX was accessible through a dedicated mobile wallet that supported fee-free payments and transfers. It was intended for peer-to-peer transactions, savings, service payments, and remittances. The project is no longer active, with its website offline and no market activity reported. Lighthouse Blockchain Technology GmbH comprised a multidisciplinary team focused on delivering decentralised, bank-free payment infrastructure.
