Robinhood’s week-old Earn product has a clear favorite, and it’s not even close. Ethena’s USDe synthetic dollar has emerged as the dominant collateral asset in the lending vault powering Robinhood’s new yield offering, with users overwhelmingly routing their deposits through the protocol.

The Earn product, which launched July 1 alongside Robinhood Chain itself, lets users lend USDG, a stablecoin issued by Robinhood, into a Morpho-powered vault curated by Steakhouse Financial. The estimated return: 7% APY from borrower interest.

How the vault actually works

Users deposit USDG into the vault, which then lends those funds to borrowers who post collateral. That collateral comes from three sources: Ethena’s USDe, Spark’s spUSDG, and Maple’s SyrupUSDG.

As of July 8, Ethena accounts for approximately $100 million of the stablecoin supply on Robinhood Chain. The total supply has surpassed $200 million, meaning Ethena represents roughly 50% of all stablecoins circulating on the chain. That’s a commanding position for a protocol that only listed its ENA governance token on Robinhood back in November 2025.

Insurance coverage for the vault has been arranged through Lloyd’s of London and RELM, covering risks associated with smart contracts and cyber threats.

Why Ethena keeps winning distribution battles

USDe works differently from traditional stablecoins like USDC or USDT. Rather than holding dollar reserves in bank accounts, Ethena maintains its peg through a delta-neutral hedging strategy, essentially holding crypto assets while shorting equivalent positions in perpetual futures. The yield comes from funding rates that perpetual futures traders pay.

What this means for investors

Robinhood had roughly 24 million funded accounts the last time it reported figures. For ENA token holders, more USDe demand generally means more protocol revenue. The token has been trading on Robinhood since November 2025, giving retail users a direct way to express a thesis on the protocol’s growth.

Ethena’s roughly 50% share of on-chain stablecoin supply suggests users and capital allocators are expressing a strong preference over the two other collateral providers, Spark and Maple. The exact asset allocation percentages among the collateral providers have not been disclosed.

The product is progressively rolling out to U.S. users. Smart contract vulnerabilities, funding rate compression, and regulatory scrutiny of yield products remain live concerns.
