Plume and Sony’s Soneium join forces to bring real-world yields on-chain

Plume, a blockchain platform purpose-built for Real World Asset Finance, has announced a strategic partnership with Soneium, the Ethereum Layer-2 network developed by Sony Block Solutions Labs. 

The collaboration aims to bring real-world asset staking and yield directly to users in the Soneium ecosystem, leveraging Plume’s native interoperability layer, SkyLink, according to a note shared with crypto.news.

The announcement details how SkyLink will serve as the technical bridge allowing yield from tokenized U.S. Treasuries, private credit, and other real-world assets to stream cross-chain into Soneium. For the 5.1 million users within the Soneium network, this opens direct access to institutional-grade yield products, without needing to leave their home ecosystem.

“At Plume, we’re committed to advancing RWAs to grow the entire crypto ecosystem,” said Chris Yin, CEO of Plume. “We’re excited to partner with Soneium to accelerate previously inaccessible yield opportunities. The future of RWAfi isn’t about keeping assets siloed, but enabling real yield to move across chains.”

Soneium’s involvement 

Sony Block Solutions Labs, a joint initiative between Sony Group Corporation and Web3 firm Startale Group, develop Soneium. 

The blockchain is designed for consumer and creator use cases and is preparing to launch mini-apps through the LINE messaging platform.

 Soneium has also partnered with Plume ecosystem participant Moca Network to expand into areas such as anime IP (like Solo Leveling), gaming, and digital identity.

“The ability to offer access to real-world yield through tokenized assets is a major step forward in making blockchain relevant for mainstream finance,” said Ryohei Suzuki, Director of SBSL. “This partnership with Plume unlocks a compelling new layer of value for our ecosystem and users.”

With more than 180 projects already building on Plume, the network positions itself as the first full-stack RWA chain, offering EVM compatibility, a tokenization engine, and integrated financial infrastructure. 

The partnership with Soneium is seen as a major step in Plume’s vision of creating an interconnected RWAfi network—enabling real-world assets and their yields to flow between different blockchains.

PLUME is up 10% on the news, according to crypto.news data.
