Stablecoin Milestones! Fidelity chooses Uniswap for liquidity, Ethena partners with Coinbase on yield pools

June 12, the stablecoin ecosystem welcomes a double boost: Fidelity selects Uniswap as the liquidity infrastructure for FIDD stablecoin, and Ethena partners with Coinbase to launch the first USDe yield pool on Morpho. Both developments point to the same trend— the boundary between traditional finance and DeFi is rapidly converging, with stablecoins as the hub.

• Fidelity chooses Uniswap: the foundational DeFi layout for traditional finance
• Ethena partners with Coinbase: DeFi yields integrated into exchange apps
• Parallel trend: the "bidirectional integration" of stablecoin infrastructure

On June 12, two major developments occurred in the stablecoin field, advancing simultaneously from both TradFi and DeFi sides. Fidelity announced its choice of Uniswap as the liquidity infrastructure for its stablecoin FIDD, while Ethena collaborated with Coinbase to launch its first stablecoin yield pool on the Morpho protocol.

Fidelity chooses Uniswap: the foundational DeFi layout for traditional finance

Uniswap officially announced on X platform that Fidelity has formally selected the Uniswap protocol as the liquidity infrastructure for its stablecoin FIDD, with the FIDD liquidity pool now live. This indicates Fidelity views Uniswap’s automated market maker (AMM) mechanism as the core pillar of its stablecoin liquidity.

FIDD is issued by Fidelity’s stablecoin unit, launched in February, and open to both retail and institutional investors. Choosing Uniswap instead of building a proprietary order book or centralized market maker reflects Fidelity’s recognition of DeFi infrastructure maturity—Uniswap’s total trading volume has exceeded $300 billion, and its v3 concentrated liquidity model allows market makers to provide deeper quotes with lower capital efficiency.

This move by Fidelity is not just about its own product. When Fidelity, managing over $800 billion in assets, entrusts stablecoin liquidity to a decentralized protocol, the likelihood of other TradFi institutions following suit increases significantly. The next competitive dimension for stablecoins has shifted from “who issues” to “who provides better liquidity infrastructure.”

Ethena partners with Coinbase: DeFi yields integrated into exchange apps

Ethena also announced on X that its first product in collaboration with Coinbase is now live—the stablecoin yield pool launched by SteakhouseFi, based on Ethena’s USDe stablecoin executing on the Morpho protocol, now directly accessible within Coinbase App for users in the US and abroad.

Morpho is the “wallet layer” of decentralized lending protocols, allowing users to build custom lending strategies on top of underlying protocols like Aave. The USDe yield pool routes funds through Morpho to the highest-yield lending markets, enabling Coinbase users to earn stablecoin yields better than savings accounts with a single click.

This is the first time a DeFi product has entered mainstream visibility in the form of an “exchange-native experience.” Coinbase has over 8M active users, and Ethena’s collaboration with Morpho provides a replicable template for other DeFi protocols: no wallet switching required, no need to understand on-chain operations, yield products embedded directly into the exchange interface.

Parallel trend: the “bidirectional integration” of stablecoin infrastructure

These two pieces of news may seem independent but point to the same structural change: the stablecoin ecosystem is undergoing a “bidirectional integration.”

Fidelity’s path is TradFi → DeFi: traditional financial institutions choosing DeFi protocols as liquidity infrastructure. Ethena’s path is DeFi → TradFi: native DeFi products reaching retail through exchange channels. Both are mirror images, representing that stablecoins are no longer just “intermediary currencies” in crypto but are becoming a convergence point for TradFi and DeFi.

Combined with recent announcements from Japan’s three major banks (Mitsubishi UFJ, Sumitomo Mitsui, Mizuho) planning to jointly issue stablecoins by 2026, and two licensed stablecoin issuers in Hong Kong expected to launch regulated stablecoins mid-year, the global stablecoin infrastructure layout has entered an accelerated phase in 2026.

The next phase of stablecoin competition will focus on three key dimensions: liquidity depth (Uniswap providing AMM liquidity for FIDD), yield efficiency (Morpho routing USDe dynamically), and channel reach (Coinbase bringing DeFi yields into exchange apps). Whoever can excel simultaneously on all three fronts will define the standards for the next-generation stablecoin ecosystem.
