Liquity USD (LUSD) is a decentralised stablecoin minted through the Liquity Protocol, a blockchain-based lending platform founded in 2021. Operating without direct centralised oversight, LUSD maintains a stable value pegged to the US dollar by collateralising Ether (ETH). Users deposit ETH to mint LUSD, promoting a mortgage-free borrowing process that ensures efficiency and stability. The system utilises an innovative mechanism called the Stability Pool, designed to handle liquidations efficiently. This system ensures LUSD remains stable even during volatile market conditions. By employing over-collateralisation and algorithmic adjustments to safeguard its value, Liquity USD is an essential tool for both decentralised finance (DeFi) enthusiasts and businesses seeking reliability without relying on centralised financial institutions.
