How nUSDT works, end to end

No magic, one loop: your USDT collateralizes a TRX loan, the TRX becomes Energy, the Energy earns fees from the busiest stablecoin network on Earth.

1. The market that pays you

TRON is where USDT actually moves: $91.9B circulating, $22B+ transferred daily. Every transfer consumes a network resource called Energy. A wallet without Energy burns ~6.5–13 TRX per transfer; renting Energy costs 50–70% less, so wallets, exchanges and payment processors rent constantly. Whoever stakes TRX and delegates its Energy collects that rent — currently 10–15% APY on the TRX, plus ~3% for Super Representative voting. That is the fee stream nUSDT taps.

2. The delta-neutral loop

  1. Deposit. Your USDT is supplied to JustLend as collateral (earning ~2% supply interest by itself).
  2. Borrow. The vault borrows TRX against it, sized to stay well clear of the liquidation threshold, with automatic deleveraging if the market moves against it.
  3. Stake & delegate. Borrowed TRX is staked (Stake 2.0) and its Energy delegated to rental pools; votes go to SRs.
  4. Neutrality. The staked TRX asset exactly offsets the TRX debt. If TRX doubles or halves, both legs move together — your dollar value doesn't care.

Net yield = energy rent + voting + supply interest − borrow cost − operations. At August 2026 rates that nets out around 5–6% on capital.

3. How the rate you see is set

The vault publishes a rate (the one in the calculator) and accrues it into the nUSDT share price at daily clearings. The rate is floating: it is recalculated from realized trailing yield × 0.85 and can change on any clearing day — the retained 15% builds a smoothing buffer that covers weak weeks and pays out as visible bonuses in strong months. There is no promised level, in either direction; a rate that survives a bad month by decree is a rate someone is paying for out of sight. What the contract does enforce is speed: the share price cannot move more than 0.3% at any single clearing, nor more than 1.2% across any rolling 7 days. The rest of the trust story is the first-loss tranche that takes losses before you do, and the rate history above — every reading we have ever set, on-chain, bad months included.

4. The withdrawal lifecycle

  1. Request. You burn nUSDT; an exit ticket with your amount is recorded on-chain.
  2. Netting. Most tickets are paid from incoming deposits within days — money leaving meets money arriving, and only the difference touches the strategy.
  3. Unstake path. If netting isn't enough, the vault unstakes TRX — a 14-day timer set by TRON itself, plus up to 7 days of energy-pool notice. Hence the published 21-day SLA.
  4. Claim. Ticket flips to READY; you claim USDT minus the 0.3% fee.

The 14-day unstake is not a bug — it is the reason the yield exists. Capital that can't flee instantly is exactly what the energy market pays a premium for.

5. What the team runs vs what the code enforces

Our backend decides when to rebalance, route liquidity between pools, and run clearings. The contracts decide what is possible at all: hot keys can only move funds along whitelisted paths, deposits need AML-signed permissions, the alpha tranche eats losses first, and every position is publicly readable. If our servers vanished tomorrow, your shares, tickets, and the fund's positions would still be verifiable on-chain.
