Ether.fi Launches USD Stablecoin on Ethena as Tether Share Slips to 80%

Ether.fi has launched a US dollar stablecoin called ether.fi USD, built on Ethena's whitelabel infrastructure, converting more than $300 million in existing deposits into the new token, crypto outlet BSCN reported. The company has not published the coin's backing mix. The launch lands as ether trades at $2,611.73, down 3.56% over 24 hours, with $13.24 billion in daily volume, and bitcoin sits at $83,854, down 2.14%, per live market data at 02:25 UTC today.

Context — why every crypto platform now wants its own dollar

A stablecoin is a crypto token designed to hold a steady value of one US dollar. The best known, Tether's USDT and Circle's USDC, are backed mainly by cash and short-term US government debt. That backing earns interest, and the issuer keeps it.

For a platform holding billions of dollars of someone else's stablecoin, that is income flowing out of the door. Blockchain infrastructure firm BlockEden estimated that Hyperliquid, a crypto derivatives exchange, held $5.97 billion in USDC, worth roughly $240 million a year in interest at a 4% Treasury yield. Platforms were effectively lending money interest-free to the stablecoin issuer.

Issuing a house stablecoin lets a platform keep that income, or share it with users. Hyperliquid launched its own coin, USDH, and wallet provider MetaMask has mUSD. The same BlockEden analysis found Tether and Circle's combined market share fell from 91.6% in March 2024 to about 80% by October 2025, as newer coins gained ground.

The catalyst is structural, not cyclical. Building a stablecoin from scratch means handling custody, reserves, exchange relationships and liquidity. Ethena sells a shortcut: a partner launches its own branded stablecoin while Ethena handles issuance, custody and reserve management. The partner controls product design and distribution, and Ethena says the process takes weeks rather than years.

Ether.fi fits that template. The platform, best known for staking ether, described itself in August as a next-generation crypto neobank, and a house dollar sits naturally alongside its staking and payment products.

Data — what the numbers show

Ethena's whitelabel roster now spans several chains. Jupiter, a trading platform on the Solana network, has jupUSD. Sui, a separate blockchain, has suiUSDe. MegaETH, a newer Ethereum-based network, has USDm, which it uses to help subsidise network fees. Ether.fi joins with more than $300 million in converted deposits.

The before-and-after on incumbent share is the sharpest figure. Tether and Circle commanded 91.6% combined in March 2024; by October 2025 that stood at about 80%, a decline of roughly 11.6 percentage points.

Metric	Value
Tether + Circle share, March 2024	91.6%
Tether + Circle share, October 2025	~80%
Hyperliquid USDC holdings	$5.97B
Implied annual interest at 4% Treasury yield	~$240M
Ether.fi deposits converted	>$300M

The peer comparison matters. USDtb, issued by Anchorage Digital Bank, is backed by US dollars and BlackRock's BUIDL fund, which holds short-term government debt. That is close to a traditional reserve-backed stablecoin. USDe is different: Ethena's own synthetic dollar holds crypto assets and offsets their price swings with short futures positions, so gains and losses on the two sides roughly cancel out. Much of its yield comes from funding rates, the regular payments between buyers and sellers of perpetual futures.

Jupiter's jupUSD combines USDtb and USDC, while suiUSDe combines USDe and USDC. Two coins that both say USD can therefore carry quite different risks.

Analysis — what it means for markets, sectors and tickers

The second-order effect runs through Ethena. Each new partner adds demand for its issuance infrastructure and potentially for USDe and USDtb as backing assets, which ties Ethena's growth to how many platforms sign up. That is a distribution bet as much as a product bet.

For incumbent issuers, the threat is gradual rather than sudden. Tether and Circle still hold the overwhelming majority of stablecoin value, and the roughly 11.6-point share decline took nineteen months to accumulate. House coins have to win deposits one platform at a time.

The risk for traders is fragmentation. Liquidity split across many smaller dollar tokens can mean wider spreads and slower redemptions under stress. A venue that settles in jupUSD cannot frictionlessly absorb flow denominated in suiUSDe or ether.fi USD without a conversion step, and each conversion is a place where slippage appears.

There is a counter-argument worth weighing. If house coins are mostly backed by USDtb, the ecosystem gains dollar tokens with genuinely bank-grade reserves, and fragmentation is a modest price. If they lean on USDe, the stablecoin label carries futures-market risk that holders may not expect. Ethena itself states that USDe is not the same as a fiat stablecoin like USDC or USDT. If demand for leveraged crypto bets weakens, funding rates fall and so does the yield. The structure also relies on exchanges and custodians.

Positioning follows the disclosure gap. Until backing mixes are published, the market cannot fully price the difference between these coins, and desks that need certainty will keep defaulting to the incumbents they can model.

Outlook — what to watch next

The first catalyst is Ether.fi's own disclosure. Watch whether the company publishes the backing mix for ether.fi USD, alongside whether holders earn yield and how redemptions work. A coin mostly backed by USDtb would behave much like a conventional stablecoin, while heavier reliance on USDe would tie it more closely to crypto futures markets.

The second is adoption. Growth beyond the converted deposits will show whether users choose the coin rather than simply receiving it. That distinction separates a genuine product from a balance-sheet relabelling.

The third is the share trend. If more platforms follow, stablecoin liquidity could split across many smaller brands, and the roughly 80% incumbent share becomes the level to watch for further erosion.

On price, ether at $2,611.73 and bitcoin at $83,854 give the risk backdrop. Both are lower over 24 hours, with bitcoin's $1.68 trillion market cap and $29.69 billion daily volume keeping it the deepest collateral pool in crypto.

Frequently Asked Questions

What does ether.fi USD mean for retail investors?

It means a new dollar token is available from a platform known for staking ether, but the label alone tells you little. Ether.fi has not published the backing mix, so retail holders cannot yet verify whether the coin behaves like a bank-reserve stablecoin or carries exposure to crypto futures funding rates. Before holding any new stablecoin, check what backs it, not just what it is called.

What happens next for Ethena's whitelabel partners?

Ethena handles issuance, custody and reserve management while partners control design and distribution, and it says onboarding takes weeks rather than years. That speed means more launches are plausible. Existing partners already span Solana, Sui and MegaETH, so the next signal is whether Ether.fi publishes its backing mix and whether holders earn yield.

Why did Tether and Circle's market share fall?

BlockEden's analysis attributes the decline to house stablecoins from platforms such as Hyperliquid and MetaMask, which let venues keep reserve interest instead of routing it to an outside issuer. Combined share moved from 91.6% in March 2024 to about 80% by October 2025. That is a nineteen-month drift, not a single event, which is why the incumbent position remains dominant.

Bottom Line

Ether.fi's dollar token extends Ethena's distribution, but undisclosed backing keeps its true risk unpriceable.
