JustLend DAO Circular Lending Strategy
Within the TRON DeFi ecosystem, there is one structure that deserves a closer look:
A circular lending model built with sTRX + USDD.
What it does is actually quite simple:
It combines staking rewards + lending liquidity + reinvestment into a structure that can amplify returns.
1️⃣ Start with the most basic cycle
① TRX → sTRX (Earn staking rewards)
Stake TRX to receive sTRX (Staked TRX).
Current yield: approximately 4.69% APY (variable).
Essentially, this turns your TRX into a yield-bearing asset.
② sTRX → USDD (Unlock liquidity)
Deposit sTRX into the USDD Vault to mint USDD.
The key point is:
You do not sell your TRX, yet you obtain a usable amount of liquidity in the form of USDD.
2️⃣ From here, there are two paths
Once you receive USDD, you have two options:
Path A (Conservative): Deposit and earn interest
→ Deposit into JustLend DAO
→ Earn USDD deposit yield (for example, by participating in the current USDD V2.0 Phase 16 Deposit Mining Campaign, currently offering around 3.98% APY).
Your total return becomes:
sTRX staking rewards + USDD deposit yield
A straightforward dual-yield strategy.
Path B (Advanced): Swap back to TRX and repeat
USDD → TRX (swap via SUN or another DEX)
→ Stake again
→ Receive sTRX
→ Deposit into the USDD Vault
→ Mint USDD again
Then simply repeat:
TRX → sTRX → USDD → TRX → …
3️⃣ What is this strategy actually doing?
Once you begin looping, you’re effectively using the same initial capital to continually increase your exposure.
With each cycle:
Your sTRX holdings increase (earning more staking rewards).
Your USDD debt increases (your borrowing position grows).
Your total asset exposure increases (creating leverage).
4️⃣ Where do the returns come from?
This isn’t a single-source yield strategy—it combines three layers of returns.
① sTRX yield
Generated from:
Super Representative (SR) voting rewards
Energy rental income
② USDD capital utilization
Path A: Earn stablecoin deposit interest.
Path B: Convert USDD into additional TRX exposure.
③ The compounding effect of looping
One unit of capital creates a larger sTRX position, increasing the amount of yield-generating assets.
5️⃣ Why does this structure work?
Because all three of these conditions exist simultaneously:
The collateral itself generates yield (sTRX).
The borrowed asset (USDD) remains fully usable.
On-chain liquidity allows repeated conversion between TRX and USDD.
Your collateral continues earning while the borrowed funds are also put to work.
6️⃣ Risks
① Liquidation risk
If TRX falls in price, your collateral ratio declines, increasing the possibility of liquidation.
② Leverage risk
This strategy effectively creates a leveraged TRX position, meaning price volatility is magnified.
③ Interest rate risk
sTRX yield is variable.
USDD borrowing costs are also variable.
If the spread between returns and borrowing costs narrows, overall profitability decreases.
④ Liquidity risk
USDD ↔ TRX conversions rely on on-chain liquidity.
During extreme market conditions, slippage may increase significantly.
⑤ Protocol risk
This strategy depends on multiple components:
Staked TRX
USDD Vault
SBM
DEXs
Any issue within one component may affect the overall strategy.
7️⃣ Who is this for?
Suitable for users who:
Have DeFi experience.
Can actively manage collateral ratios.
Understand leveraged strategies.
Not suitable for users who:
Want completely passive, hands-off yield.
Cannot tolerate liquidation risk.
Summary
This is a classic structured on-chain strategy on JustLend DAO:
Use a yield-bearing asset as collateral to borrow liquidity, then convert that liquidity back into the underlying asset and repeat the process to amplify yield exposure.
