Usual is an innovative decentralized stablecoin project that uses U.S. Treasury bills as collateral and incorporates Ethereum smart contracts to provide transparency and security. It mints USD0 stablecoins through two methods: direct deposit of RWA (Real World Assets) or indirect deposit of USDC/USDT. Users can earn USUAL tokens or base interest yields by staking USD0. Usual has also launched a Pills activity where users can earn Pills by minting and holding USD0++ as well as providing liquidity, giving them an opportunity to receive USUAL airdrops. The project aims to combine the advantages of centralized stablecoins with the transparency of blockchain, offering users a safe and reliable stablecoin option.
