June 12 brought two notable developments in stablecoins. Fidelity selected Uniswap as the liquidity infrastructure for its FIDD stablecoin, while Ethena partnered with Coinbase to launch the first USDe yield pool on Morpho. The announcements came from different corners of the market, but they point in the same direction: stablecoins are becoming the clearest meeting point between traditional finance and DeFi.
Fidelity puts FIDD liquidity on Uniswap
According to Uniswap’s post on X, Fidelity has officially chosen the Uniswap protocol as the liquidity infrastructure for FIDD, and the FIDD liquidity pool is already live. FIDD is issued by Fidelity’s stablecoin unit and was formally launched in February, with access open to both retail and institutional investors.
The choice matters because Fidelity did not rely on an in-house order book or a centralized market-making setup. Instead, it placed an automated market maker model at the center of its stablecoin liquidity design. The source material notes that Uniswap has processed more than $300 billion in cumulative trading volume, and that its v3 concentrated liquidity model allows market makers to quote deeper liquidity with lower capital usage.
The article also says Fidelity manages more than $800 billion in assets. When a large traditional financial firm assigns stablecoin liquidity to a decentralized protocol, the competitive frame shifts. The question is no longer limited to who can issue a stablecoin; it also extends to who can deliver the stronger liquidity infrastructure behind it.
USDe yield reaches users inside the Coinbase app
On the same day, Ethena said on X that its first product with Coinbase had gone live. The product, launched by SteakhouseFi, is built around Ethena’s USDe and runs on the Morpho protocol. It is now available directly in the Coinbase app for users in the United States and overseas markets.
Morpho is described in the source as a wallet layer for decentralized lending, letting users build custom lending strategies on top of base protocols. In this setup, the USDe yield pool routes capital through Morpho toward lending markets offering higher returns, giving Coinbase users app-level access to stablecoin yield with a simple in-app action.
This stands out because a DeFi yield product is being presented through a native exchange experience rather than through a separate on-chain workflow. The source says Coinbase has more than 8 million active users. For DeFi protocols, that model lowers the need for wallet switching and reduces the amount of on-chain know-how required from users.
A two-way convergence in stablecoin infrastructure
These two items look separate on the surface, but they mirror each other structurally. Fidelity represents a TradFi-to-DeFi route, with a traditional financial institution using a decentralized protocol as liquidity infrastructure. Ethena represents a DeFi-to-TradFi route, with a natively DeFi product reaching retail users through a major exchange channel.
The source frames this as a broader two-way convergence in stablecoin infrastructure. In that view, stablecoins are no longer just an intermediary asset inside crypto markets. They are becoming the point where liquidity depth, yield efficiency, and user distribution meet across both systems. The article also references moves outside this pair of announcements: Japan’s three major banks—Mitsubishi UFJ, Sumitomo Mitsui, and Mizuho—plan to jointly issue a stablecoin within 2026, while two licensed stablecoin issuers in Hong Kong are expected to launch regulated products around midyear. Taken together with the Fidelity and Ethena developments, the buildout of global stablecoin infrastructure is accelerating.
Using the source’s framework, the next stage of competition centers on three fronts: liquidity depth, yield efficiency, and distribution reach. The FIDD and USDe announcements each address a core part of that shift.
