R25 rcUSD Vault redefines stablecoin DeFi opportunities—delivering a potential fixed yield of 12% for a full 12-month cycle with flexible liquidity.

R25, the institutional-grade RWA protocol, and Ember Protocol, a leading provider of vault products on Sui incubated by the team behind Bluefin, today announced the upcoming launch of Ember Protocol’s flagship fixed-yield vault product in December as a part of R25 and Ember Protocol’s continuous collaboration. Ember Protocol’s R25 rcUSD Vault enables its users to enjoy rewards sourced from R25’s yield-bearing tokens and ecosystem incentives. In a strategic partnership with TopNod wallet, a decentralized self-custodial wallet built with security and simplicity, the R25 rcUSD Vault will unlock a rare opportunity to access a fixed 1-year yield with a potential base APY of 12%, plus an additional 2% boost for the first three months to eligible users.

Unlike traditional products, the R25 rcUSD Vault features flexible liquidity. Users of the vault can withdraw their deposits at any time without a lock-up period, with settlement payment available within 4 days (T+4). The R25 rcUSD Vault will officially open for deposits soon via TopNod Wallet, and the initial vault size is limited to $7 million USD.

The DeFi landscape has long been plagued by "predatory APY" — incentives that start unrealistically high to attract liquidity, only to suffer from rapid dilution shortly after.

Ember Protocol aims to break this cycle. “Our goal with Ember Protocol is to build a resilient financial infrastructure that democratizes wealth management,” said Ibra Brabery, Co-Founder of Ember Protocol. “This partnership with R25 and TopNod reflects a shared commitment to sustainable, long-term growth. By bringing institutional-grade real-world assets on-chain through a seamless and secure gateway, we are laying the foundation for a transparent ecosystem where users can allocate capital with confidence.”

To ensure this institutional-grade product is accessible to a broader audience with ease, R25 and Ember Protocol selected TopNod as the vault’s exclusive wallet partner. As a decentralized, self-custodial wallet which provides users with a secure and intuitive tool to view, manage, and interact with digital assets, TopNod lowers the barrier to entry for DeFi without compromising on security. The wallet offers a seamless "Seedless" onboarding experience where users can create an account using just an email and password, removing the friction of traditional seed phrase management.

Behind this simplicity lies TopNod’s Key Sharding and TEE (Trusted Execution Environment) technology. TopNod user's access code is cryptographically split into three shards, stored respectively on the user's mobile device, a TEE, and an enterprise-grade secure server.

This architecture ensures that the access code never exists in a single location and cannot be reconstructed without the user's authorization, making the user’s private key inaccessible to any single third party.

The R25 rcUSD Vault will officially open for deposits soon, and the initial cap is limited to $7 million USD. Users can download the TopNod wallet (topnod.com) and prepare their assets in advance to secure the allocation.
