Plume, a blockchain network focused on real-world asset finance, has partnered with OpenTrade to launch a new line of yield-bearing vaults through its staking protocol, Nest.
The vaults, backed by tokenized funds from asset manager WisdomTree, will offer stablecoin holders returns tied to regulated financial instruments, according to a company statement issued on Monday.
The collaboration integrates OpenTrade’s real-world asset (RWA) yield infrastructure with Plume’s on-chain environment, enabling users to earn returns on USDC and USDC.e through vaults that automatically accrue interest.
The system uses OpenTrade’s on-chain vault framework, which adheres to ERC-4626 and ERC-7540 standards to ensure transparent tracking between on-chain balances and underlying assets.
WisdomTree, which manages over $130 billion globally, provides the tokenized funds that underpin the new vaults.
The initial offerings include the WisdomTree Government Money Market Digital Fund (WTGXX) and the WisdomTree Private Credit and Alternative. Income Digital Fund (CRDT), both of which are expected to anchor future vault launches.
Plume said it has committed $2.5 million in USDC to seed liquidity for the initiative.
Users can deposit stablecoins into Nest to receive vault tokens representing their positions, with the ability to withdraw both principal and accrued yield at any time.
Teddy Pornprinya, co-founder and CBO of Plume, said the partnership “bridges institutional assets, compliant infrastructure, and on-chain distribution,” allowing DeFi users to access “transparent stablecoin yield backed by real, institutional-grade assets.”
OpenTrade, which is backed by a16z Crypto and Circle, will manage and scale the stablecoin yield products supporting Nest’s vaults.
The firm’s asset manager, Five Sigma, oversees fund transfers and reporting under UK Financial Conduct Authority supervision.
Maredith Hannon, Head of Digital Asset Business Development at WisdomTree, said the integration “highlights how regulated, tokenized strategies can serve as building blocks for on-chain finance.”
By pairing stablecoin deposits with regulated tokenized funds, Plume and its partners aim to provide users with access to predictable, real-world yields through blockchain-native interfaces.
