JUST

What is JUST?

JUST (JST) is the governance token of the JUST DeFi ecosystem on TRON, including JustLend DAO, a lending market where users supply and borrow tokens such as USDT and TRX. JST holders vote on protocol settings, and since 2025 protocol revenue has funded JST buybacks and burns. The ecosystem is closely tied to TRON and its founder, Justin Sun.

What it’s used for

TRON users supply and borrow assets on JustLend DAO without needing JST. JST holders vote on proposals such as interest-rate models, collateral factors and new markets. Eligible JustLend and JUST ecosystem revenue is used to buy JST on the market and burn it.

Role of the JST token:

Evidence of real use

• JustLend's documentation describes JST as a TRC-20 governance token with an initial maximum supply of 9.9 billion and an ongoing buyback-and-burn program. Source
• The JustLend DAO community approved a JST buyback-and-burn proposal on October 21, 2025, and has announced completion of multiple burn rounds. Source
• In March 2026 the SEC filed a proposed settlement with TRON-linked Rainberry over wash trading and dismissed remaining claims against Justin Sun and TRON entities. Source

How JUST works

JustLend DAO is a pooled lending market on TRON. You supply a token, such as USDT or TRX, to earn interest from borrowers, or you post collateral and borrow against it. Rates rise and fall with demand, and if your collateral's value drops below the required level, your position can be liquidated. None of this requires JST; the token's job sits one level up, in governance and value capture.

JST holders vote on proposals that set interest-rate models, collateral factors, reserve settings and which markets are listed. Since late 2025, a community-approved program uses eligible JustLend and JUST ecosystem revenue to buy JST on the open market and burn it, which reduces supply over time. How much is burned depends on how much revenue the protocols earn. Burn rounds are announced publicly, so you can check the onchain records yourself.

Key moments

1. 2020JST launches on TRON in May, and the JustLend lending market follows later that year.
2. 2023The SEC sues Justin Sun and TRON-related entities over alleged unregistered offerings and wash trading.
3. 2025JustLend DAO approves a JST buyback-and-burn program in October and begins executing burns.
4. 2026The SEC resolves its TRON case in March with a $10 million proposed settlement for Rainberry and dismissal of other claims.

Supply

JST started with a maximum supply of 9.9 billion tokens on TRON. The community-approved buyback-and-burn program removes tokens over time using protocol revenue, so circulating supply shrinks as burns accumulate. The pace of burns depends on JustLend and JUST ecosystem earnings.

Risks to understand

• Ecosystem concentration: JUST depends heavily on TRON and on teams associated with Justin Sun, so issues there can spill over to JST.
• Smart-contract and liquidation risk: lending protocols can be exploited, and borrowers can be liquidated in fast markets.
• Governance concentration: a small number of large holders can effectively decide votes.
• US access: JustLend is a DeFi protocol rather than a US-licensed service, and JST is not listed on every US exchange, so check your platform and understand you are using unregulated software.
