[DigitalToday reporter Chi-gyu Hwang (황치규)] Stablecoin yield infrastructure project Ocero has raised $13.5 million.

According to a recent report by CoinDesk, the investment round was co-led by the Sky ecosystem and Plasma. USDT0, Maple, Accountable, Four Pillars, RedStone, The Rollup, and angel investors from Kairos Research also participated.

Ocero is a project incubated by Stablewatch and Sorter Labs. The stablecoin market has exceeded $300 billion in size, based on DeFiLlama, but yields generated from the assets backing it remain concentrated with issuers such as Circle and Tether. As a result, holders find it difficult to earn yields directly, and fintech companies also struggle to offer stablecoin savings products unless they manage assets themselves.

Ocero offers 3 products. Ocero Earn is designed to let wallets, neobanks, custodians and exchanges attach the Sky Savings Rate to their own services. Deposits are linked to the Sky Savings Rate, while Ocero handles asset management, fund routing and risk-management infrastructure.

The Ocero app lets users access the rate directly across multiple chains. Ocero Foundry supports asset managers and structured product issuers in bringing yield products on-chain.

Sky has expanded distribution centered on USDS and sUSDS after changing its name from MakerDAO. Standard & Poor's last year assigned Sky a credit rating for the first time for a DeFi protocol, and the rating was B-. Projects backing Sky are also expanding into yield-bearing real-world asset products. Obex said in March it would allocate $1 billion to credit, energy and AI assets to expand stablecoin yields.

Plasma is developing a stablecoin-focused blockchain. Plasma raised $373 million through token sales amid oversubscription early last year.
