What Is JustLend? Step-by-Step Guide to Using It in 2025

JustLend is TRON’s flagship on-chain money market: you can supply assets to earn interest, turn deposits into collateral, borrow against that collateral, and take part in DAO governance with the JST token. Thanks to TRON’s fast finality and low fees, JustLend offers a smooth, cost-efficient way to manage on-chain credit in 2025.

Quick start: open the official app at JustLend.

What Is JustLend?

JustLend is a decentralized lending/borrowing protocol (money market) on TRON. When you supply an asset, you earn variable interest that auto-accrues. If the market supports it, you can enable the deposit as collateral and borrow other assets against it. Interest rates are algorithmically set per market and adjust with utilization (the ratio of borrowed to supplied liquidity). Protocol changes—like listings and collateral factors—are governed by the community via JST.

Why It JustLend Matters in 2025

Low friction: TRON’s low gas costs make frequent rebalances and repayments practical.

Capital efficiency: Utilization-driven rates and per-asset collateral factors help direct liquidity where it’s needed.

Self-custody & transparency: You keep your keys and can audit everything on-chain.

Community governance: JST holders can tune parameters (LTVs, caps, listings) through proposals and votes.

How JustLend Works

1) Supply → Earn → jTokens

Supplying an asset mints an interest-bearing representation (a jToken). Your jToken balance increases over time as interest accrues. If the asset allows, toggling “use as collateral” raises your borrow limit.

2) Borrow Against Collateral

Borrow power depends on per-asset collateral factors (LTV ceilings). Your account’s health (risk score) aggregates collateral value, borrowed value, and liquidation thresholds. If health hits the threshold, liquidators can repay part of your debt and seize collateral at a discount.

3) Interest-Rate Model

Rates move with utilization. Tight markets (high utilization) push borrow APR up—lifting supply APY—to attract liquidity and discourage excessive borrowing. Looser markets do the opposite. This feedback loop keeps markets liquid.

4) Risk Levers

Markets can include reserve factors, supply/borrow caps, and emergency pause switches. These controls help protect liquidity during volatility or oracle incidents.

Core Features at a Glance

Multi-asset markets: Supply/borrow across TRON-native and supported bridged assets.

Composability: Positions integrate with other TRON DeFi strategies and tools.

Real-time telemetry: Utilization, rates, and caps are transparent on-chain.

DAO governance (JST): Proposals can adjust LTVs, listings, and reserves.

Step-by-Step: Using JustLend Safely

Open the app & connect → Welcome to JustLend
and connect a TRON-compatible wallet (e.g., TronLink; hardware wallets via Web3 bridges).
Supply an asset → Start with a small test deposit; you’ll receive jTokens that accrue interest automatically.
Enable collateral (optional) → Toggle “use as collateral” on supported assets to increase your borrow limit.
Borrow conservatively → Stay well below the max; leave a 25–40% health buffer to absorb volatility.
Monitor & maintain → Track utilization, borrow APR, and your account health; repay or add collateral as conditions change.
Record-keeping → Export transactions for accounting/tax reporting; document your rebalance decisions.

Strategies to Maximize Net APY

Diversify collateral: Avoid highly correlated assets to reduce liquidation cascades.

Maintain a buffer: Keep room above liquidation thresholds; markets can move quickly.

Favor steady earners: Supplying stablecoins offers smoother APY; rotate only when utilization or premia justify it.

Repay tactically: If borrow APR spikes (high utilization), partial repayment can quickly restore health and cut interest drag.

Batch actions: TRON fees are low, but batching deposits/withdrawals and collateral toggles still saves over time.

Risks You Must Manage

Market/oracle risk: Fast moves can degrade health; set alerts and track dashboards.

Smart-contract risk: Audits help but don’t eliminate risk. Size positions prudently; keep long-term funds in cold storage.

Liquidity risk: Near 100% utilization, immediate withdrawals may be constrained; consider staged exits.

Governance risk: Parameter changes (LTVs, caps) can affect your borrow limit; follow proposals if you’re leveraged.

Fees & What You’ll Actually Pay (or Earn)

Borrow APR / Supply APY: Variable per market via utilization; previewed in-app before confirmation.

Reserves: A portion of interest can accrue to protocol reserves (an indirect cost to suppliers).

Network fees: TRON gas is typically low, but frequent compounding/rebalancing still adds up—optimize cadence.

Security, Audits & Transparency

Open-source contracts enable public review and independent audits; see JustLend GitHub

Guardian/pause controls (where implemented) can mitigate emergencies.

On-chain data (utilization, caps, rates) lets you self-verify assumptions in real time.

Who JustLend Is Best For

Passive earners supplying blue-chip assets for programmatic yield.

Active users borrowing against diversified collateral with prudent buffers.

Governance participants who want to influence listings and risk parameters via JST.

JustLend DAO FAQ (2025)

Q1: Do I need JST to use JustLend?
No. You can supply and borrow without JST. JST is required for governance (proposals/votes).

Q2: What are jTokens?
Interest-bearing representations of your deposits; balances grow automatically as interest accrues.

Q3: How is my borrow limit calculated?
By applying per-asset collateral factors to the USD value of your enabled collateral; volatile assets usually have lower LTV ceilings.

Q4: What triggers liquidation?
If your health hits the liquidation threshold (e.g., price drops or rising borrow APR), liquidators can repay part of your debt and seize collateral at a discount.

Q5: Can I withdraw anytime?
Generally yes—except when market utilization is extremely high (near 100%) and liquidity is temporarily tight.

Q6: Are rates fixed or variable?
Variable, set per market by utilization. You’ll see the current APR/APY before confirming a transaction.

Q7: How do I minimize liquidation risk?
Borrow less than the max, keep a healthy buffer, diversify collateral, and react early to volatility.

Q8: Are there extra rewards beyond interest?
Depending on program settings and markets, incentives may exist. Check the live app for current details.
