RedStone provides USDY with a price feed and SEP-40 contract, making it collateral-eligible on Stellar's lending protocols. The yield-bearing stablecoin, backed by U.S. Treasuries, joins Stellar's growing RWA ecosystem—now $2.96B in tokenized assets, including sovereign debt and Bitcoin products.
Ondo's USDY, a yield-bearing stablecoin backed by U.S. Treasuries with $2.1B circulating value, now has a price feed and SEP-40 contract support on Stellar via RedStone. This enables USDY to be listed as collateral on Blend and Templar, Stellar's primary lending protocols. Collateral eligibility is the difference between an asset sitting dormant and one functioning in DeFi. RedStone has been expanding SEP-40 infrastructure across Stellar throughout 2026, building feeds for USDC, EURC, XLM, sovereign debt instruments, Bitcoin products, and tokenized funds. The standard gives any protocol a unified interface to consume pricing without custom integration work. Stellar's RWA ecosystem has grown to approximately $2.96B in tokenized assets—roughly 3x since early 2025. USDY joining the SEP-40 pipeline reflects the progression of larger, higher-profile yield-bearing assets moving from issuance to DeFi utility.
