What Is JustLend DAO? A Plain-English Guide to Lending on TRON
JustLend DAO is the largest lending protocol on the TRON network. It is built on the Compound V2 architecture, which is a fancy way of saying it works like a money market: people deposit assets to earn interest, and other people borrow those assets against collateral. If you have used a lending app on another chain, the shape will feel familiar. If you have not, this guide walks through the whole thing in plain English — what justlend is, how the moving parts fit together, and how to use it without getting liquidated.
The core idea: supply and borrow
Two sides, two roles. Suppliers put assets into a market and earn interest on them. Borrowers post collateral and borrow against it, paying interest for the privilege. The interest a supplier earns comes from the interest a borrower pays. The rate is not fixed; it moves with utilization — how much of a market's supplied pool is currently borrowed. A market that is nearly fully borrowed pays suppliers a high rate; a market sitting idle pays almost nothing.
JustLend DAO currently runs around fifteen token markets. You can see the full list on the dashboard or the Markets page, and you can filter by the token you already hold.
jTokens: the receipts you must not lose
When you supply an asset, the protocol gives you jTokens in return. A jToken is a receipt — proof that you supplied the underlying asset and that you are owed it back, plus the interest it has accrued. jTRX for supplied TRX, jUSDT for supplied USDT, and so on.
One rule matters more than the rest: do not transfer your jTokens to anyone. They are the claim on your deposit. Send them away and you have sent away the deposit and the yield it earned. Treat them like the keys to the position, because that is exactly what they are.
How to supply
Find the market you want to supply to on the dashboard or Markets page, and click Supply. The first time you supply to a market you will be asked to approve the contract — this is a one-time permission for that token. Make sure you have some TRX set aside for transaction fees (energy and bandwidth on TRON), or the supply transaction can fail before it lands.
Once you confirm, you receive the matching jTokens. If the market is enabled as collateral, your supplied assets also raise your borrow limit — meaning they now back any borrowing you do.
How to borrow (and the risk value that keeps you safe)
Before you can borrow, you need to have supplied assets to at least one collateral-enabled market. Then pick the asset you want to borrow, enter an amount, and sign.
The number to watch is the risk value. By default the safe upper limit is 80. You can raise it to 90 if you want to borrow more aggressively, but in that mode you should watch the risk bar closely. When the bar turns red, your account is one market move away from liquidation. Borrowing is useful; borrowing up to the line is how accounts get liquidated.
Repay and withdraw
Repaying returns the borrowed asset and reduces your risk value. Withdrawing pulls your supplied asset back out — but only up to the amount that is not currently locking a borrow. If your collateral is already backing a loan, you can only withdraw the part that is free.
Liquidation, and how to avoid it
If your risk value climbs to 100, your account is eligible for liquidation. A liquidator repays part of your debt and takes some of your collateral in return, usually at a discount. That discount is the liquidator's profit and your loss. The way to avoid it is the way you would expect: keep the risk value down, and do not borrow volatile assets against stable collateral without a buffer.
Beyond supply and borrow: sTRX and energy rental
JustLend DAO does more than lending. You can stake TRX to receive sTRX, a liquid-staked token that keeps your TRX productive while staying usable as collateral. There is also energy rental, which lets you rent TRON energy at a discount — useful if you transact often and want to cap your fee costs.
JustLend DAO and the JST token
The DAO part is not decoration. JustLend DAO is governed by holders of JST, the protocol's native governance token. JST holders stake it as stJST to vote on proposals — JustLend Improvement Proposals, or JIPs — that decide which markets get added, how parameters are tuned, and how mining rewards are distributed. If you use justlend seriously, holding and staking JST is how you get a say in how it evolves.
Getting started
The flow is the same one every time: connect a TRON wallet, supply an asset to a market you are comfortable with, decide whether to borrow against it or just earn, and keep an eye on the risk value if you do. The dashboard shows your positions, your health factor, and the rewards you have earned. Start small, learn how utilization and liquidation feel, and scale up only once the mechanics are intuitive.
The short version: justlend is a place to put idle TRON assets to work and to borrow against them at fair, utilization-driven rates. JustLend DAO is the protocol and the community that runs it. Used carefully, both are straightforward; used carelessly, both are expensive. The rest is practice.
