Soneium enhances blockchain utility by providing access to tokenized financial assets in collaboration with Plume.

Soneium, Sony’s public blockchain, is collaborating with Plume, the full-stack layer 1 chain built for scaling Real World Asset Finance (RWAfi), to deliver real-world asset staking and yield opportunities to Soneium’s user base.

As part of the partnership, Soneium will integrate SkyLink—Plume’s native interoperability layer. This will enable real-world asset value and yield to flow securely cross-chain, Plume said in a recent announcement.

Through this integration, Soneium’s 5.1 million users can gain access to asset-backed yield products, including tokenized US Treasuries and private credit, directly from the Plume chain.

Plume CEO Chris Yin said the partnership supports the company’s mission to make real-world assets more accessible and interoperable across blockchain ecosystems.

The goal, he said, is to allow users to tap into institutional-grade yield products and help drive more mainstream adoption of RWA-based finance in crypto.

“The future of RWAfi isn’t just about assets living on a single chain, but enabling real yield to flow seamlessly wherever users are,” Yin stated.

Soneium, developed as a joint initiative between Sony Group Corporation and Startale Group, is preparing to launch blockchain-powered mini-apps through LINE. The platform recently partnered with Moca Network to expand into digital identity, anime, and gaming experiences.

Ryohei Suzuki, Director of Sony Block Solutions Labs, said the partnership with Plume allows Soneium to connect the world of blockchain with tangible financial returns from real-world assets. This makes Web3 and blockchain technology more practical and relevant to everyday financial activities.

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

Last month, YZi Labs, formerly known as Binance Labs, announced that it had made investments in Plume Network to expand the Real World Asset Finance ecosystem.

Plume’s blockchain, which is EVM-compatible, supports a diverse range of RWAs, including financial instruments, carbon credits, and collectibles, among others. The platform currently hosts over 180 projects built on its network.
