Soneium and Plume Bring Tokenized US Treasuries and Private Credit Yields Onchain

Plume , a modular Layer-2 blockchain for Real World Asset Finance ( RWAfi ), has partnered with Soneium , an Ethereum Layer-2 open blockchain developed by Sony Block Solutions Labs , to provide Soneium’s users with RWA staking and real-world yield through Plume’s native interoperability layer SkyLink.

Per the press release shared with Cryptonews, the SkyLink integration enables users to stream real-world asset value and yield securely cross-chain. Therefore, they get access and exposure to asset-backed yield products, including yield from tokenized US Treasuries and private credit from the Plume chain, the team claims.

The email states that the launch will “leverage a real-world asset distributor managing more than $4 billion in tokenized assets, including products from Ondo Finance , a major issuer of tokenized US treasuries.”

Furthermore, the integration forms “an interconnected RWAfi network” to speed up mainstream RWA adoption.

Plume CEO Chris Yin commented that the blockchain aims to advance RWAs in order to grow the crypto ecosystem as a whole. The partnership with Soneium will “accelerate previously inaccessible yield opportunities for over 5.1 million users in their ecosystem.”

“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 says.

According to Ryohei Suzuki, Director of Sony Block Solutions Labs, “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. This partnership with Plume unlocks a compelling new layer of value for our ecosystem and users.”

Plume Price and Soneium TVL Rising

Plume says it’s a full-stack RWA Chain and ecosystem with more than 180 projects building on it. It offers an end-to-end tokenization engine, a network of financial infrastructure partners, and an EVM-compatible environment for onboarding and managing diverse RWAs.

“Anyone can tokenize real-world assets, distribute them globally, and make them useful for native crypto users,” the team claims.

At the time of writing, the PLUME token trades at $0.189. It’s up 11% in a day, 8.3% in a week, and 12.4% in a month.

The coin hit its all-time high of $0.2475 in March 2025. It has decreased by 23.1% since.

Meanwhile, Soneium is a Layer-2 blockchain built on Optimism’s OP Stack , developed by Sony Block Solutions Labs, a joint initiative established by Sony Group Corporation and Startale Group.

Soneium’s total value locked (TVL) has recently surpassed $100 million, now standing at $155.48 million, according to DeFiLlama. It’s up 15% over the past 24 hours.

Earlier in April, Astar , a collective promoting Web3 adoption, partnered with decentralized protocol AltLayer and restaking protocol EigenLayer to build a Fast Finality Layer for Soneium .

In March, Soneium joined hands with game software and venture capital company Animoca Brands and San FranTokyo , a core contributor to Anime Foundation . Animoca Brands’ flagship digital identity infrastructure platform, Moca Network , will create a premier identity layer on this blockchain. With this move, Soneium aims to expand into digital identity, popular anime like Solo Leveling, and gaming experiences, the press release says.

Also in March, Soneium partnered with Japanese social media platform LINE to bring four gaming applications on-chain.
