ARCx, a synthetic asset mining project, has launched STABLEx, a stablecoin pegged 1:1 to the US dollar. Users can lock yUSD (yyDAI, yUSDC, yUSDT, yTUSD) as collateral to create STABLEx, and can also exchange STABLEx for USDC, USDT, or DAI in liquidity pools, or deposit STABLEx into savings contracts to earn rewards.
