Ether.fi launches own stablecoin ether.fi USD on Ethena's infrastructure

Stablecoins issued by crypto platforms are slowly eroding the market share of Tether and Circle. These house coins keep the interest from reserve assets within the platform instead of passing it to an external issuer. That poses a long-term risk to the incumbents rather than an immediate one. For Ethena, every new partner increases demand for its infrastructure and potentially for USDe and USDtb as backing assets, so its growth depends on how many platforms adopt the service. For traders, the downside is fragmentation: liquidity scattered across multiple smaller dollar tokens can lead to wider bid-ask spreads and slower redemptions during periods of stress. Without disclosure of backing compositions, the market cannot accurately assess the differences between these coins.

The name 'USD' on a stablecoin does not reveal the underlying risk profile, which depends entirely on the reserve assets. Ether.fi's entry into the stablecoin market underscores a broader shift: platforms no longer want to lend their users' deposited funds interest-free to Tether or Circle. Yet the label of a stablecoin says far less about its safety than what backs it.

• According to crypto outlet BSCN, Ether.fi has introduced ether.fi USD, built on Ethena's whitelabel infrastructure, and is converting over $300 million of existing deposits into the new token.
• Ether.fi has not disclosed the backing composition of the coin.
• Ethena's whitelabel service allows partners to launch their own stablecoins, with Ethena managing issuance, custody, and reserves.
• Current Ethena partners include Jupiter with jupUSD, Sui with suiUSDe, and MegaETH with USDm.
• Backing options range from USDtb, a bank-issued coin backed by dollars and BlackRock's BUIDL fund, to USDe, a synthetic dollar whose return is tied to futures funding rates.
• BlockEden data shows that Tether and Circle's combined market share dropped from 91.6% in March 2024 to around 80% by October 2025.

Crypto outlet BSCN reported that Ether.fi, a platform primarily known for staking ether, has launched a US dollar stablecoin named ether.fi USD, built on Ethena's infrastructure. The report says Ether.fi is converting over $300 million of existing deposits into this new token. The company has not yet released details on the coin's backing. This move is the latest in a trend where crypto platforms that previously depended on third-party stablecoins are now creating their own.

Crypto platforms have strong reasons to want their own dollar token. A stablecoin is a crypto token designed to maintain a value of one US dollar. The most well-known examples, Tether's USDT and Circle's USDC, are mostly backed by cash and short-term US government debt. That reserve earns interest, which the stablecoin issuer keeps. For a platform that holds billions of dollars of another company's stablecoin, that means a significant amount of income is leaving the platform. Blockchain infrastructure firm BlockEden estimated that Hyperliquid, a crypto derivatives exchange, held $5.97 billion in USDC, which at a 4% Treasury yield would generate roughly $240 million annually in interest. Essentially, platforms were providing an interest-free loan to the stablecoin issuer.

By issuing its own stablecoin, a platform can retain that interest income or distribute it to users. Hyperliquid launched its own stablecoin called USDH, and wallet provider MetaMask introduced mUSD. According to the same BlockEden analysis, the combined market share of Tether and Circle dropped from 91.6% in March 2024 to approximately 80% by October 2025, as these newer stablecoins gained traction.

When a platform issues its own stablecoin, the interest earned on the reserves remains within the platform instead of going to an external issuer.

Ethena offers a whitelabel service that simplifies stablecoin issuance. Creating a stablecoin from scratch involves managing custody, reserves, exchange relationships, and liquidity. Ethena provides a shortcut via its whitelabel service. Under this arrangement, a partner introduces its own branded stablecoin while Ethena takes care of issuance, custody, and reserve management. The partner has control over product design and distribution, and according to Ethena, the process can be completed in weeks instead of years.

Ether.fi would become one of multiple existing Ethena partners. Jupiter, a Solana-based trading platform, issues jupUSD. Sui, an independent blockchain, has suiUSDe. MegaETH, a newer Ethereum-based network, uses USDm to help cover network fees. For Ether.fi, which in August referred to itself as a next-generation crypto neobank, a house dollar aligns well with its staking and payment offerings.

Stablecoins with the same name can have vastly different backing. For users, the critical factor is not which entity issues a stablecoin, but what assets support it. Ethena's whitelabel coins can be backed by various assets, and partners have the ability to adjust the composition.

One backing option is USDtb, issued by Anchorage Digital Bank and supported by US dollars and BlackRock's BUIDL fund, which holds short-term government debt. This type is similar to a traditional reserve-backed stablecoin.

Another option is USDe, Ethena's 'synthetic dollar'. Instead of holding cash, USDe holds crypto assets and hedges price movements with short futures positions, so gains and losses approximately offset each other. Most of its return derives from funding rates, the recurring payments between long and short positions in perpetual futures. Ethena itself says USDe is different from fiat-backed stablecoins like USDC or USDT. If demand for leveraged crypto trading declines, funding rates drop, reducing the yield. The structure also depends on exchanges and custodians.

Partners may also use other approved stablecoins like USDC, or a combination. For instance, Jupiter's jupUSD is a blend of USDtb and USDC, while suiUSDe mixes USDe and USDC. Consequently, two stablecoins both labeled 'USD' can have markedly different risk profiles.

The primary point to watch is whether Ether.fi publishes the backing composition for ether.fi USD, along with details on yield for holders and redemption mechanics. A coin primarily backed by USDtb would function like a traditional stablecoin, while a greater reliance on USDe would link it more closely to crypto futures markets. Expansion beyond the initial converted deposits will indicate whether users actively choose the coin rather than just receiving it. On a larger scale, if more platforms follow suit, stablecoin liquidity could become fragmented across numerous small brands. The takeaway is straightforward: before using any new stablecoin, verify its backing assets, not just its name.
