EtherFi, the crypto neobank and Ethereum restaking protocol with nearly $6 billion in total value locked (TVL), is integrating Plume Network's Nest Vault infrastructure to give its users access to tokenized real-world asset (RWA) yield.
The integration centers on Plume's nBASIS vault, powered by Superstate's USCC fund, which generates returns from basis spreads, the price differential between spot and futures markets, across multiple cryptocurrencies, including Bitcoin, Ether, Solana, and XRP.
The rollout will proceed in two phases. EtherFi will first re-allocate capital to the nBASIS vault, with a direct integration into EtherFi's user interface to follow.
“We're building a neobank where every yield source, whether onchain or offchain, lives under one roof. This partnership with Plume and Superstate is a major step toward making that real,” said an Etherfi spokesperson.
"DeFi yields are increasingly compressed in today's market," said Plume co-founder Teddy Pornprinya, adding that retail users onboarded through neobanks like EtherFi are seeking more sustainable and diversified return sources beyond native DeFi strategies.
Plume's Nest Vault framework handles compliance, risk parameters, and onchain reporting, reducing operational overhead.
From Restaking to Neobank
EtherFi began as a liquid restaking protocol on Ethereum, allowing users to stake ETH while retaining liquidity through its eETH token. The protocol launched a credit card product in mid-2024, positioning its Cash card as part of a broader product suite designed to let users save, invest, and spend crypto without off-ramping.
CEO Mike Silagadze has described the end goal as a full financial stack: salary deposits, savings, earning yield, and everyday spending, all within EtherFi. The project branded the concept a "defibank" blending traditional banking UI with DeFi-native yields and non-custodial infrastructure.
EtherFi migrated its Cash accounts and card program from Scroll to Optimism's OP Mainnet in February 2026, bringing over 70,000 active cards and roughly 300,000 user accounts to the Superchain as part of an enterprise partnership with OP Labs.
The Plume integration now adds an RWA yield layer, extending the platform's offerings beyond native DeFi strategies.
