jstWhat is JUST?
JST is a TRC-20 token on TRON and the governance token used by the JUST/JustLend DAO ecosystem. The current protocol documentation links it to JustLend's lending markets, liquid TRX staking through sTRX, and Energy Rental. Holding JST is not the same as holding USDJ, a claim on reserves, or a guaranteed share of protocol revenue.
What problem does JUST solve?
TRON users may want to lend assets, borrow against collateral, stake TRX without giving up a transferable token, and obtain transaction Energy. JUST/JustLend groups these functions into on-chain markets and uses JST for governance and selected incentives. This describes the protocol's stated purpose, not a guarantee that every market, reward, or future feature will remain available.
How does JUST work?
JST is transferred as a normal TRC-20 token. For governance, holders deposit JST into the WJST voting wrapper at a 1:1 ratio and use the resulting voting power in GovernorBravo proposals; successful actions pass through a 48-hour Timelock. In JustLend markets, users supply supported TRON assets and receive jTokens representing their market position; borrowers over-collateralize assets, pay floating rates set by market utilization, and can be liquidated if collateral falls below the threshold. JST can also be distributed as an incentive in eligible lending and Energy Rental programs. The contract documentation identifies upgradeable proxy components, so governance-controlled upgrades are part of the risk model.
Key facts
- JST is a TRC-20 token on TRON; the documented mainnet token contract is TCFLL5dx5ZJdKnWuesXxi1VPwjLVmWZZy9.
- The tokenomics documentation lists an initial maximum supply of 9,900,000,000 JST; it also describes buyback-and-burn activity, so circulating supply can be lower than that ceiling.
- Governance uses a separate WJST wrapper: the governance reference documents 1 JST = 1 vote, a proposal threshold of at least 200,000,000 JST, quorum of more than 600,000,000 affirmative votes, and a 48-hour Timelock after queueing.
- Current documented JustLend products are supply-and-borrow markets, sTRX liquid staking, and Energy Rental; the documentation lists 17 active and 6 legacy jToken markets.
- The JustLend supply-and-borrow system is Compound-V2-inspired: suppliers receive jTokens, borrowers use over-collateralized positions, rates respond to utilization, and unhealthy positions can be liquidated.
- The project's MiCA white paper says JST launched in April 2020, the core supply-and-borrow market launched in December 2020, and sTRX/Energy Rental launched in April 2023; it says JustStable was discontinued in May 2025.
- JST voting or reward utility does not establish a claim to USDJ reserves, a fixed yield, a guaranteed redemption value, or legal ownership of protocol assets.
- The contract reference marks key Comptroller, market, oracle, and governance entrypoints as proxy-based and upgradeable through governance; users therefore face governance and implementation-change risk.

Frequently asked questions
Is JST the same as USDJ?
No. JST is the governance and utility token. USDJ was the ecosystem's USD-pegged stablecoin, and the project's MiCA white paper says the JustStable product was discontinued in May 2025.
What can a JST holder actually do?
A holder can transfer JST and, subject to the live governance rules, deposit it into WJST to vote on JustLend Improvement Proposals. JST may also be used or distributed in eligible lending and Energy Rental incentive programs. Voting power is not a claim on protocol cash or reserves.
Does JST pay holders a guaranteed yield or revenue share?
No guarantee is established by the cited documentation. Buybacks and burns are described as a tokenomics mechanism, while lending and Energy Rental rewards depend on eligible programs and their rules; market value and rewards can change.
What is the maximum JST supply?
The official tokenomics page lists an initial maximum supply of 9.9 billion JST. It also describes burns, so the circulating amount may be lower; check on-chain data for the current figure.
Can governance change the protocol?
Yes, within the documented governance path. JST is wrapped into WJST for voting, successful proposals are queued through GovernorBravo and executed after a 48-hour Timelock, and the contract reference identifies upgradeable protocol proxies.
What are the main risks of using JustLend with JST?
Users face smart-contract and oracle risk, liquidation and market-liquidity risk, TRON network and transaction-cost risk, governance-controlled upgrades, changing incentive rules, and the possibility that rewards or products are discontinued. JST itself can also lose value.
