Summary
This SIP proposes integrating Origin Dollar into the USDC mainnet (Lower Risk) vault in the Lazy Summer Protocol.
Adding OUSD will diversify USDC yield strategies, tap into Origin’s unique rebase model, and expand will Lazy Summer’s yield-generating sources beyond standard DeFi lending protocols.
@halaprix started research on building the OUSD Ark back in April 2025 from my original OUSD Ark proposal, maybe since it was started on it can be picked up from where it was left off. Since the 2025 proposal, OUSD has gone through a simplification, both via Snapshot and via onchain governance, to optimize OUSD for gas consumption and reducing code complexity - OUSD is now solely backed by USDC.
Motivation
- Expand yield sources – Provides exposure to Morpho strategies curated jointly by Yearn & Origin and operationally managed by Yearn via Origin’s stablecoin product, adding a complementary USDC yield stream and AMO alongside existing ARKs.
- Attract new user types – Engages current OUSD holders, the Yearn community, and Morpho user base, deepening penetration into the USDC staking ecosystem.
- Increase TVL – Adds a USDC ARK, supporting Lazy Summer’s USDC vault growth objectives.
