How is USDe different from USDT?

USDT is backed by reserves (cash, US Treasuries) on Tether's accounts. USDe is a synthetic dollar backed by a delta-neutral strategy: long ETH (or other assets) + an equal short perpetual. Fundamentally different trust models.

Where does sUSDe yield come from?

Two sources: funding rate on short perps (when funding is positive the short receives payments) and staking yield on part of the collateral. As of May 2026 net yield has historically ranged 5–15% APR.

What happens if funding turns negative for a long stretch?

sUSDe yield falls or turns negative. Ethena maintains a Reserve Fund, but extended negative-funding regimes are economically challenging for the model. This is a known risk transparently disclosed in the docs.

Can USDe be used in TON DeFi?

Yes: USDe is available as a jetton via LayerZero OFT and is integrated into a subset of TON DEXes and lending protocols. Pool depth is smaller than USDT on TON, but growing.

USDe and sUSDe on TON: Ethena and the Synthetic Dollar

Ethena Labs is a protocol launched in 2024 on Ethereum that introduced a new class of DeFi instruments: USDe, a synthetic dollar backed by a delta-neutral strategy, and sUSDe, its yield-bearing version. As of May 2026 USDe is one of the largest stablecoins in crypto (per the project’s own data — in the top three by market cap), and via LayerZero OFT it is also available in the TON ecosystem.

This article unpacks the delta-neutral mechanics, how USDe differs from classic stables (USDT/USDC) and from algorithmic stables (historically UST), what risks the holder takes, and how the design is integrated on TON.

What USDe is and why it exists

USDe is a synthetic dollar. “Synthetic” here means that its backing is not dollars in a bank but a portfolio engineered to hold a stable USD value.

The base construction:

A user or market maker deposits ETH (or a liquid staking variant, stETH) into the protocol.
The protocol simultaneously opens a short perpetual on ETH on a centralized exchange for the same notional.
If ETH rallies, the long profits and the short loses an equal amount. If ETH drops — vice versa. Net P&L on ETH price = 0.
Additionally: while funding rate is positive, the short collects payments from longs — this is the portfolio’s yield.

Result: $1 of USDe is always backed by ~$1 equivalent that doesn’t depend on the price of ETH.

sUSDe: stake and yield

USDe itself doesn’t pay yield; to capture the funding-rate yield the user stakes USDe and receives sUSDe — a yield-bearing rebasing/wrapper token.

sUSDe yield is generated from:

Funding rate on short perps — main source in a bullish funding regime.
Staking yield on part of the collateral (if stETH/wstETH is used — that’s ~3% APR from the long leg).
Treasury yield on the reserve portion of USDe held in interest-bearing stables.

Per the project, average APY across 2024–2025 sat in the 5–15% range, with peaks above 20% in high-positive-funding moments.

Important: that yield is floating. During negative-funding periods (bear regime) it can drop below zero; Ethena uses its Reserve Fund to partially cushion those periods — but the fund is finite.

USDe on TON: the technical setup

USDe arrived on TON via the LayerZero OFT standard. In practice:

Ethereum, Arbitrum, BSC, and TON all hold the same token with a single supply.
Moving from Ethereum to TON: burn on Ethereum through the LayerZero channel → mint jetton on TON.
On TON USDe is a full-fledged TEP-74 jetton; it trades on STON.fi, DeDust, and can be used as stablecoin collateral in lending (EVAA Protocol).

Pool depth is smaller than native USDT on TON (where Tether ships a billion-cap native issuance) but grows as demand develops.

sUSDe on TON is more limited — at time of writing the main staking operation runs on Ethereum, so the convenient path for TON holders is: buy sUSDe on Ethereum → bridge to TON → use. No native TON staking for USDe exists yet (this may change by the time you read this).

Comparison to stables on TON

Parameter	USDT on TON	USDC (bridged)	USDe
Type	Fiat-backed	Fiat-backed	Synthetic delta-neutral
Issuer	Tether	Circle (via bridge)	Ethena Labs
TON form	Native jetton	Wrapped jetton	OFT jetton
Depeg resolves via	Tether reserves	Bridge contract	Ethena treasury
Yield	None natively	None natively	Via sUSDe
Main risk	Tether execution	Bridge security	Funding regime, exchange counterparty
Regulatory profile	Under pressure (MiCA)	MiCA-compliant	Contested

USDe is not “better” or “worse” — it is different. It’s a tool for those who want stablecoin-denominated yield without parking funds on a CEX.

Risks: what can actually go wrong

Ethena lists risks transparently in its own documentation; here’s the TON-user lens.

1. Funding rate

If funding stays negative (bear regime without short squeezes) sUSDe yield turns negative and the protocol spends Reserve Fund. A known design vulnerability. Historically across 2024–2025 funding was positive on average — no guarantee for the future.

2. Exchange counterparty

Short perps are open on CEXes (Binance, OKX, Bybit, Deribit, less often DEX perps). If a CEX defaults or freezes accounts (FTX scenario) the position is lost. Ethena diversifies across multiple CEXes and uses off-exchange settlement (Copper, Fireblocks), which reduces but does not eliminate the risk.

3. Regulatory

Synthetic stables sit in a gray zone. Under EU MiCA, USDe in its current form would not qualify as an e-money token; as of May 2026 the project is negotiating with regulators across jurisdictions. Regulatory pressure can limit distribution.

4. Liquid staking execution

Part of the long leg is stETH. A Lido incident (slashing, contract bug) hits the backing.

5. Bridge / OFT

For TON users this adds one more layer: integrity of the LayerZero channel. A LayerZero compromise could desync the USDe jetton on TON from L1 supply.

Use cases: where USDe / sUSDe make sense on TON

Yield without a CEX deposit. A TON holder unwilling to park funds on an exchange can hold sUSDe and earn funding yield on-chain. Comparable to CEX savings — without CEX custody risk.
Stablecoin collateral in DeFi. USDe on TON can serve as collateral for loans on EVAA Protocol (where integrated at time of reading).
Indirect hedge on ETH drawdown. sUSDe accrues funding yield regardless of ETH’s direction.
LP in stable pools. USDC/USDe or USDT/USDe pools (where available) — a standard stable LP with relatively low impermanent loss.

What USDe does NOT replace

Preservation of USD purchasing power (USD inflation hedge). USDe is $1, no more.
USDC-grade tax clarity. USDC is cleaner in most jurisdictions.
MiCA regulatory status. For users under MiCA jurisdictions USDe is a less convenient tool.
Protection from CEX systemic risk. USDe itself depends on functioning short infrastructure on CEXes.

Buying USDe and staking into sUSDe — in practice

Baseline path for a TON user:

Acquire USDT/USDC on any chain (Ethereum, Arbitrum, BSC) via CEX or a swap.
Swap to USDe on Ethereum (Curve), Arbitrum, BSC — or directly on a TON DEX if liquidity is there.
Stake into sUSDe on Ethereum via Ethena’s interface (signs in the Ethereum wallet).
Bridge sUSDe to TON via LayerZero if you want to use it in TON DeFi.

Alternative: buy USDe directly on TON via DEX and hold; stake later if a native TON option exists.

Fees: Ethereum gas for staking (when done there) + bridge fee dominate. For amounts under $500 fees take a noticeable cut; $5k+ is comfortable.

What this means for users: a checklist

USDe and sUSDe are not classic stables. Understand the construction.
Yield is floating; do not treat 10% APR as guaranteed.
Regulatory risk is higher than USDC; factor it into large positions.
Don’t hold 100% of stable allocation in one instrument; diversifying (USDT + USDC + USDe) reduces structural risk.
Watch Ethena’s Reserve Fund — public dashboard, check monthly.
USDe liquidity on TON is thinner than USDT; large swaps incur visible slippage.

Where the industry is heading

Several directions:

Collateral expansion beyond ETH. BTC, SOL, Solana liquid staking, basis trades on BTC — reducing single-asset funding dependence.
Institutional USDe products. DAO treasury management, yield vaults for funds.
MiCA-compliant version. A possible “USDe Europe” with different collateral and regulatory status.
Direct native TON integration. If Ethena ships a native staking contract on TON, UX for TON users improves significantly.

Conclusion

USDe and sUSDe are a notable innovation in stablecoin design, and their arrival on TON via LayerZero OFT expands the toolkit available to users. It’s neither “better than USDT” nor “the new UST” — it is a different asset class with a specific risk/reward profile.

For TON users willing to engage with the delta-neutral model and accept its risks (funding regime, CEX counterparty, regulation), sUSDe is a working route to stablecoin-denominated yield without depositing on an exchange. For those seeking maximum simplicity and regulatory clarity — USDT and USDC remain the baseline choice.
