Pyth Network has introduced a USDY/USD price feed, giving decentralized finance protocols on Aptos and Sui access to real-time pricing for Ondo Finance's yield-bearing USDY asset. The feed went live this week, marking a step forward for integrating real-world assets into these two high-performance Layer 1 blockchains.
What USDY is and why it needs a price feed
USDY is not a typical stablecoin. It's a yield-bearing note, meaning its value accrues interest over time rather than staying pegged to a fixed dollar amount. That makes accurate, up-to-date pricing essential for any DeFi application that wants to use it as collateral, in lending pools, or as a trading pair. Without a reliable oracle, protocols can't safely price USDY or manage liquidations. Pyth's feed fills that gap.
Removing an infrastructure barrier
Aptos and Sui are relatively new Layer 1 networks that have been building out their DeFi and real-world asset (RWA) capabilities. Until now, USDY lacked a dedicated price oracle on these chains, which limited its use. The Pyth feed removes that barrier, giving developers and users a trusted data source. For Ondo Finance, which issues USDY, the launch opens the door to deeper liquidity and more use cases on Aptos and Sui.
Part of a broader RWA infrastructure push
The move fits a wider trend of building granular infrastructure for tokenized real-world assets. As more traditional assets move on-chain, the need for precise, decentralized pricing data grows. Pyth's expansion into these newer chains signals that the oracle network sees demand for RWA support beyond Ethereum and its main competitors. But whether the feed gains traction depends on whether DeFi protocols on Aptos and Sui actually build products around USDY. So far, no major integrations have been announced.
The feed is live now. Adoption will be the next test.
