The two largest retail-facing trading platforms in the US are now competing for your idle stablecoins, and they’ve both picked the same DeFi protocol to do it. Coinbase and Robinhood have each built yield products on top of Morpho, the decentralized lending infrastructure that has quietly amassed over $11B in total value locked.

Two platforms, two philosophies

Coinbase launched its onchain USDC lending product via Morpho back on September 18, 2025. The yields are variable, meaning they fluctuate with supply and demand in the lending markets, and the platform has advertised rates reaching as high as 10.8%.

On top of the base lending rate, Coinbase participants can earn MORPHO token rewards. These are claimable periodically, with Coinbase One subscribers reportedly getting enhanced access.

Coinbase has also introduced two risk-tiered vault options curated by Steakhouse Financial: “Prime” and “Higher Yield.” The Prime vault carries lower risk and lower returns, while Higher Yield does what the name suggests, with commensurately more exposure.

Robinhood took a different path entirely. Its “Robinhood Earn” product started rolling out around July 1, 2026, and it targets an estimated 7% APY on USDG, its own stablecoin. Rather than letting rates float, Robinhood is fixing the yield for a year.

The Robinhood vault operates on the Robinhood Chain and is backed by insurance from Lloyd’s of London.

Why Morpho is the quiet winner

Neither platform built its own lending protocol from scratch. Both chose Morpho, which functions as permissionless lending infrastructure that lets anyone create isolated lending markets, or “vaults,” with customizable risk parameters.

Neither platform requires lockup periods. Users can deposit and withdraw based on vault liquidity, with interest accruing instantly.

What this means for investors

Coinbase’s variable model rewards active participants who understand DeFi mechanics and are comfortable with rate fluctuations. When lending demand is high, you could earn well above 7%. The MORPHO token rewards add upside, but tokens are inherently volatile.

Robinhood’s fixed 7% is designed for people who want to set it and forget it. The Lloyd’s insurance backing adds a layer of confidence that’s unusual in crypto yield products. But fixed rates carry their own risk for the platform: if market rates drop below 7%, Robinhood is subsidizing the difference. If rates spike well above 7%, users miss out on the upside.

Both Coinbase and Robinhood are publicly traded, SEC-reporting companies offering yield products built on decentralized infrastructure. The fact that regulators haven’t blocked these products, at least so far, suggests a growing tolerance for DeFi integrations when wrapped in compliant, insured, consumer-friendly packaging.
