Stablecoin cryptocurrencies have revolutionized the crypto market since their arrival more than ten years ago. Assets like USDT, USDC and other popular stablecoins have been instrumental in reducing crypto volatility and connecting the worlds of crypto and fiat currencies.
USDe is a synthetic dollar asset issued by Ethena that doesn't suffer from these common limitations of stablecoins. Backed by delta-hedging derivatives positions using perpetual and futures contracts, as well as short-term US government bond funds.
Key Takeaways:
USDe is a synthetic dollar cryptocurrency with pegged to USD, maintained via automated delta-hedging trading operations.
USDe's stability and dollar peg is ensured through opening and closing short perpetual positions for its underlying collateral assets.
USDe is a synthetic dollar asset that maintains a peg to the USD through delta hedging of its underlying assets during minting. USDe is issued by Ethena (ENA), a decentralized finance (DeFi) protocol on the Ethereum blockchain. Users can flexibly acquire, stake and sell their USDe holdings with 1:1 collateralization.
USDe can be staked for sUSDe, a globally accessible dollar savings asset redeemable for USDe. Over time, assuming the protocol is generating rewards, sUSDe should be redeemable for an increasing amount of USDe when unstaking the sUSDe for USDe.
Similar to USDe itself, sUSDe is also widely available as margin collateral on major crypto venues, though with a specific focus on decentralized trading platforms and borrow-lend protocols.
sUSDe brings dollar savings functionality to the masses, bypassing the high fees and inflexible terms often offered by traditional institutions. sUSDe provides dollar-based APY on decentralized rails, available to billions of users, right from a mobile or desktop device.
Important Note: As sUSDe accrues value against USDe, 1 tsUSDe (TON staked USDe) is equivalent to more than 1 USDe (current rate is approximately 1.18 USDe per sUSDe).
Ethena is the Ethereum-based DeFi protocol that issues USDe. Ethena Labs was founded in 2023 by its CEO, Guy Young, and the Ethena protocol launched its native cryptocurrency, ENA, in early April 2024. Although Ethena's vision extends beyond USDe, this synthetic dollar asset is its flagship product and primary focus.
To maintain apeg to the US dollar, USDe utilizes a delta-neutral strategy involving short positions on derivatives markets. This allows the value of USDe to remain stable despite being backed by volatile cryptocurrencies.
To mint USDe, KYC’d & whitelisted users provide assets such as USDC & USDT and receive USDe in return.. The protocol doesn’t require overcollateralization, which is often a burden in decentralized stablecoin systems like that of Dai (DAI). Instead, USDe maintains a 1:1 collateral ratio, which improves capital efficiency.
Once collateral is deposited, Ethena buys a digital asset such as BTC or ETH and opens a corresponding short perpetual futures position on a derivatives exchange via OES. This position offsets the price risk created by the BTC or ETH, ensuring the value of the backing assets remain constant in USD terms..
For example, when a user deposits USDT as collateral and the protocol purchases ETH & hedges the price risk with a perpetual contract:
If the price of ETH increases, the value of the collateral rises, but the short position incurs an unrealized loss; ensuring the USD value of the backing assets remains constant.
If the price of ETH decreases, the collateral loses value, but the short position incurs an unrealized gain, ensuring the USD value of the backing assets remains constant.
This delta-hedging model ensures that the total portfolio value remains stable, preserving the dollar peg of USDe.
All minting and redemption operations on Ethena are managed by smart contracts. To ensure pricing accuracy, Ethena integrates with multiple oracle systems, including Pyth and RedStone, and data feeds from centralized exchanges such as Bybit. This redundancy mitigates price manipulation risks and ensures robust peg maintenance.
Unlike traditional stablecoins that rely on single-custodian models, USDe adopts an Off-Exchange Settlement (OES) model. Collateral is held by independent custodians, separate from trading venues, reducing counterparty risk and improving systemic resilience.
The Ethena reserve fund serves as a critical stability mechanism for USDe. This dedicated pool of assets provides an additional layer of security and acts as a financial buffer against unexpected events in the crypto markets.
The fund consists primarily of highly liquid assets, including USDtb, USDC, USTB, sSUSDS, and sDAI. This diversified composition ensures that the reserve remains resilient across various market conditions.
During periods of negative funding rates or market incidents, the reserve fund is available to cover any losses to the backing assets of USDe to ensure USDe remains fully collateralized.
The reserve operates transparently, with regular updates on its composition and size. The Reserve Fund can be viewed onchain in real-time. Through Ethena's governance system, the reserve fund's management adapts to evolving market conditions, allowing for strategic adjustments to better secure USDe's stability as the DeFi industry changes.
USDe benefits from Ethena's governance framework, which allows for strategic adaptation and community input. Protocol decisions regarding reserve fund composition, collateral management policies and other key operational aspects can evolve through this system as market conditions change.
The protocol’s governance structure enables responsiveness to new market developments and regulatory landscapes. For example, Ethena can adjust which assets are accepted as collateral, or determine how the reserve fund is allocated across different instruments, based on changing liquidity conditions in the market.
This adaptability is particularly important for maintaining USDe's security and stability over time. As DeFi’s environment evolves, governance decisions can implement technical and risk management enhancements that protect Ethena's integrity and user assets.
Its governance mechanism provides transparency around protocol changes, with decisions about USDe's operations and security measures documented and accessible. This open approach helps build confidence among users that the platform can adapt, while maintaining its commitment to security and stability.
USDe is available on Bybit's Spot market through swap pairs with several leading large-cap cryptocurrencies, including BTC, ETH, SOL, USDT and USDC.
USDe includes many innovative features that users must evaluate when comparing it to traditional stablecoin options.
USDe's innovative delta-hedging model delivers key advantages over traditional dollar-pegged assets. USDe generates rewards in excess of retained by USDT & USDC and distributes those rewards to partners such as Bybit who shares them with users.
USDe’s backing assets are stored with custodians and on-chain in 24/7 auditable solutions. This structure enhances the security and accessibility of the collateral that backs USDe.
The synthetic dollar also has significant advantages over decentralized stablecoins. Probably the biggest advantage is the absence of over-collateralization requirements. Some decentralized stablecoins, such as Dai, require ample over-collateralization to ensure stability. However, for many users, it almost defies logic to provide 150% or even more in collateral value – quite a usual requirement for algorithmic assets – to secure stablecoin funds.
Owing to its unique peg-maintenance mechanism, USDe can operate without such onerous over-collateralization requirements. This mechanism also helps USDe achieve high levels of scalability, making it a useful asset for transaction and value storage within the DeFi ecosystem.
Theoretically, USDe faces funding risk during prolonged negative funding rates, which could affect its stability mechanism if it exceeds the Reserve Fund balance.
Although the Off-Exchange Settlement system is diversified, it still introduces some custodial risk if the entities that are managing collateral experience operational issues. Additionally, USDe depends upon the continued operation of the derivatives exchanges in which hedging positions are being maintained.
Ethena has implemented multiple safeguards to address these concerns, including its reserve fund and multi-exchange approach. These measures help mitigate potential vulnerabilities, though users should maintain awareness of underlying risk factors when incorporating USDe into their crypto strategies.
USDe stands apart in the stablecoin ecosystem through its innovative delta-hedging approach to maintaining a dollar peg. This technical architecture represents a significant advancement in the operation of US dollar pegged assets without the traditional weaknesses of alternate stablecoins. As USDe continues to mature, its unique combination of capital efficiency and proven stability positions it as a compelling option for users seeking a secure, dollar-pegged asset in the cryptocurrency space.
