Ethena (ENA)

Ethena (ENA) is the governance token of Ethena, a protocol that issues USDe, a synthetic dollar designed to hold a value of one US dollar without being backed by dollars in a bank. Instead, USDe is backed by crypto assets such as ether and bitcoin, paired with short positions in futures markets that cancel out their price swings. ENA holders vote on how the protocol is run and can stake the token for rewards.

ENA is a separate asset from USDe. USDe is the dollar-like token people hold and spend, while ENA is a volatile token whose value depends on the protocol's growth. Ethena also offers sUSDe, a staked version of USDe that earns the protocol's revenue, and USDtb, a more conventional stablecoin backed mainly by tokenised Treasury funds.

Imagine a farmer who owns a field of wheat but wants a steady income, not one that rises and falls with the wheat price. Before harvest, the farmer agrees to sell the crop at today's price. If wheat prices crash, the field is worth less but the agreement pays off; if prices soar, the field is worth more but the agreement costs money. Either way, the farmer's total stays roughly the same.

Ethena does the same with crypto. It holds coins and, at the same time, takes a bet that their price will fall. The two sides balance, so the combined pot stays near one dollar for each USDe issued. On top of that, traders on the other side of the bet often pay Ethena a regular fee, and that fee is the main source of the yield passed to people who stake USDe.

Ethena Labs was founded by Guy Young, and USDe launched publicly on Ethereum on 19 February 2024. It grew quickly, helped by high yields and a points campaign that rewarded early users. The ENA token launched on 2 April 2024, when 750 million tokens, 5 percent of the supply, were given away in an airdrop to early users. USDtb followed in December 2024. USDe's supply reached about $14.8 billion by early October 2025, then fell sharply after the market crash of 10 October 2025, dropping to around $6.4 billion within weeks as holders redeemed.

The method is a form of hedging called a delta-neutral position: for every unit of crypto Ethena holds, it opens an equal short position in perpetual futures. The value of the combined position is:

• $Q$ is the quantity of the crypto asset held, for example the number of ether.
• $P_0$ is the price when the position is opened.
• $P$ is the current price.
• $Q \times (P_0 - P)$ is the gain or loss on the short futures position.

For example, if Ethena holds 10 ether bought at 3,000 dollars each and shorts 10 ether of futures, the position starts at 30,000 dollars. If the price falls to 2,400 dollars, the ether is worth 24,000 dollars but the short has gained 6,000, so the total is still $10 \times 3{,}000 = 30{,}000$ dollars. The hedge removes price risk, not every risk. The collateral is held with off-exchange custodians while the shorts sit on major exchanges, and Ethena earns funding payments and staking income on the collateral. Direct minting and redemption of USDe are limited to approved firms that pass KYC checks; everyone else buys and sells it on the open market.

• Governance. ENA holders vote on risk settings, supported collateral and other parameters, part of the protocol's wider governance process.
• Staking. ENA can be staked as sENA, which earns rewards from partner projects and is the intended recipient of any future share of protocol revenue.
• Revenue sharing. In November 2024 the market maker Wintermute proposed a "fee switch" to pass part of Ethena's revenue to sENA holders; Ethena later set conditions for turning it on, with activation left to further governance steps.
• Collateral and trading. ENA is listed on most large exchanges and used as collateral in some lending markets.

ENA has a fixed total supply of 15 billion tokens, of which about 1.4 billion circulated at launch; the rest unlocks over several years for investors, contributors, the foundation and ecosystem funding.

USDe's yield depends on futures funding rates, which can turn negative when traders are pessimistic, so the protocol keeps a reserve fund to cover losses. Other risks include the failure of an exchange or custodian, and the gap between USDe's market price and its backing during panics. On 10 October 2025 USDe briefly traded as low as 65 cents on Binance, whose internal pricing relied on its own order book, while it stayed close to one dollar elsewhere; Binance later compensated affected users. Critics argue that a dollar token reliant on derivatives is closer to a fund than to a stablecoin, and holders should treat it as a yield-bearing product with risks that ordinary fiat-backed coins do not carry, including depegging.
