Mountain Protocol vs Ondo Finance: Yield-Bearing Stablecoin Comparison 2026
Mountain Protocol's USDM and Ondo Finance's USDY represent two approaches to yield-bearing stablecoins backed by US Treasuries. Both aim to bring treasury yields on-chain, but they differ in structure, accessibility, and compliance approaches. This comparison helps investors choose the right tokenized treasury product.
Product Overview
Mountain Protocol USDM is a yield-bearing stablecoin that automatically rebases to reflect treasury yield. Holders earn ~5% APY simply by holding USDM, with yield distributed through daily balance increases. The token is designed as a savings vehicle for dollar-denominated yield. Ondo Finance USDY is a tokenized note backed by US Treasuries and bank deposits. USDY earns yield (~5% APY) through the underlying treasury holdings. The token is designed for both retail and institutional users seeking compliant treasury exposure.Yield Mechanism Comparison
USDM Yield Mechanism
- Type: Rebasing stablecoin
- Yield Delivery: Daily balance increases
- Rate: ~5% APY (tracks short-term treasury rates)

USDY Yield Mechanism
- Type: Value-accruing token
