Just is a decentralised finance platform built on the TRON blockchain, focusing on lending and stablecoin issuance. It aims to provide a fair and open financial services platform where users can participate in staking, lending, and governance without intermediaries. Just utilises the JST token for governance, paying interest, and participating in other activities within the ecosystem. The platform's key feature is its stablecoin lending services, which allow users to stake TRX to generate USDJ, a stablecoin pegged to the US dollar.
