USD* Junior
USD*-J — The Amplified Tranche of USD*
1. What is USD*-J?
USD*-J is the junior tranche of USD*. It is a way to earn enhanced yield in exchange for defined first-loss exposure within the USD* capital stack.
Think of it this way: USD* generates yield for everyone. But not everyone takes the same amount of risk. USD*-J holders volunteer to stand at the front of the line — if something goes wrong, their position absorbs the impact first, shielding the senior holders (regular USD* holders) behind them. In return, they earn a meaningfully higher share of the yield.
It's not leverage. Rather, It is a deliberate choice to take on more responsibility and get paid for it.
2. How does it work?
There are 2 ways to access USD*-J via the Perena application ( perena.org/invest )
Directly Deposit into USD* Junior vault (Link)
Amplify your current USD* position by the “Amplify” toggle and allocate using the slider.
When you amplify USD* into the junior tranche, your tokens are held in an escrow vault. You still earn yield from the same USD* — but the yield is split differently.
Perena uses a dynamic leverage factor to divide yield between senior and junior holders. At launch, the base multiplier is 2x, meaning junior stakers earn roughly twice the APY of senior holders. But here's what makes it interesting: the fewer people who stake in the junior tranche, the higher the junior APY goes. The system self-balances, much like how a lending market adjusts interest rates based on utilization.
When yield is earned: Junior's share is calculated by weighting their TVL by the leverage factor. If junior represents 25% of TVL at a 2x multiplier, they receive a disproportionately larger slice of the total yield.
When a loss occurs: they are first applied to the junior tranche up to its allocated share of total capital. For example, if the junior tranche represents 25% of TVL, senior capital is insulated from losses until aggregate losses exceed that 25% threshold. Only after the junior allocation has been fully utilized would senior holders begin to experience impact.
Technical footnote: Yield distribution uses a weighted formula: junior weight = junior TVL × leverage factor, senior weight = senior TVL × 1x. Total yield is split proportionally by weight. The leverage factor scales dynamically as junior stake % drops below the 25% target, the multiplier increases (up to ~3x at very low stake levels), creating a natural incentive to rebalance.
3. What are the underlying assets?
USD*
The token you stake. You must already hold USD*
Your USD* moves into an escrow vault, and your USD*-J position is tracked on-chain.
4. What are the risks?
USD*-J is a medium-risk position. Here's what that means, honestly:
USD*-J positions absorb losses first. If USD* experiences a depeg, the staked position takes the hit before any senior holder is affected. USD*-J does not change the underlying counterparty risks of USD* .
Your returns are variable. The APY depends on how many people are staking in junior. More stakers = lower individual APY (but more total protection for senior). Fewer stakers = higher APY (but you're absorbing risk with a thinner buffer).
This is not a guaranteed return. In a severe scenario, you could lose part or all of your junior tranche USD*.
What protects you:
The diversified, market-neutral, premium quality of USD* already minimizes depeg risk
The dynamic leverage factor incentivizes rebalancing — if the junior tranche gets too thin, higher APY attracts new stakers to rebuild the buffer
Early redemption fees discourage panic exits that would destabilize the tranche

5. How do withdrawals work?
Redeeming from USD*-J is not instant by default. This is by design — the cooldown protects the tranche from sudden exits that would leave senior holders exposed.
Standard unstake
7 days
0.50% (50 bps)
Perena protocol revenue
Instant unstake
None
1.00% (100 bps)
Redistributed to remaining junior stakers
If junior stake drops below 10% of TVL (an emergency threshold), the instant unstake fee increases to 10% (1000 bps) to discourage further exits and protect the system.
When you unstake, you receive your proportional share of the junior tranche's current value — not your original stake amount. If the tranche has earned yield, you'll receive more than you put in. If it has absorbed losses, you'll receive less.
Important: Once you initiate a standard unstake, the 7-day clock starts. Your tokens remain in escrow during this period and continue to earn yield (and absorb risk) until the cooldown completes.
6. Who is this for?
USD*-J is for users who understand the tradeoff between risk and reward — and are willing to lean into it. If you believe USD* is fundamentally sound and want to earn more from the same underlying yield, junior is how you express that conviction. Think of it as the difference between holding an index fund and writing insurance on it: same underlying, different posture, different payout.
This is not for passive holders who want set-and-forget simplicity. For that, regular USD* is the right choice.
