JUST

JUST (JST) is the governance token of the JustLend and Just ecosystem on the Tron blockchain. The Just protocol was one of the first significant decentralized finance systems built on Tron, offering collateralized stablecoin issuance and later a lending market.

The original product allowed users to lock TRX as collateral and mint USDJ, a dollar-pegged stablecoin, in a design broadly similar to the collateralized debt position model pioneered on Ethereum. The ecosystem later expanded into JustLend, a money market where users supply assets to earn interest and borrow against collateral, which became the largest lending venue on Tron.

Role of the token

JST is used for governance over the protocol's parameters, including collateral ratios, stability fees, and the assets the system supports. It is also used to pay certain fees within the ecosystem. Because Tron's transaction costs are low and its user base is heavily concentrated in stablecoin transfers, the Just ecosystem's activity profile differs from comparable protocols on Ethereum.

Supply

JST has a maximum supply of 9.9 billion tokens. Total and circulating supply both currently sit at roughly 8.19 billion, meaning the great majority of the maximum has already been issued and is in the market.

The project is closely associated with the wider Tron ecosystem and its founder, and that association is worth noting when evaluating governance: protocols with concentrated founding influence tend to have governance outcomes that reflect that concentration regardless of formal token voting. Anyone assessing JST should look at current protocol usage and revenue rather than at the token's early history.
