Reservoir srUSD (SRUSD) is a yield-generating stablecoin created by the Reservoir protocol. It functions as a liquid savings instrument that permits users to generate returns on stablecoin holdings without requiring funds to be locked up, with returns sourced from a wide range of digital and real-world asset holdings.
srUSD represents a key product within the Reservoir protocol framework, which seeks to develop a scalable and decentralized stablecoin infrastructure. The protocol's objective centers on delivering a collection of financial products organized around its foundational stablecoin, rUSD, enabling participants to receive steady returns from a varied asset composition. The infrastructure operates on Ethereum with supplementary support across additional blockchains, including Berachain.
The Reservoir protocol encompasses multiple interconnected financial instruments. The foundational stablecoin, rUSD, can be generated by users using diverse collateral options. srUSD (Savings rUSD) serves as the protocol's primary savings option, enabling users to contribute rUSD in exchange for variable returns. For those preferring alternative yield mechanisms, the protocol provides trUSD, which accommodates time-restricted deposits with predetermined yields. The broader ecosystem includes open-access lending capabilities and a governance token designated as DAM. Returns on srUSD derive from the protocol's underlying holdings, which are selected to maintain superior quality standards and reduced fluctuation relative to competing protocols.
As of October 18, 2025, Reservoir reported cumulative locked assets of $526 million with an annual yield rate of 7.75% on srUSD holdings. The protocol highlights capabilities including backing from numerous asset types and rapid access to capital for its offerings. The srUSD asset is structured to permit continuous daily interest accumulation while preserving user access to their holdings.
The Reservoir protocol revealed plans for srUSD deployment on November 7, 2024, introducing it as an interest-accruing stablecoin without deposit duration restrictions. The product became operational on November 11, 2024. Upon introduction, srUSD delivered a 6% annual yield and launched with a maximum issuance of $25 million, with expansion capacity contingent on user participation growth. The introduction was attributed to Fortunafi, signaling their involvement in the protocol's technical advancement or organizational oversight.
A noteworthy milestone transpired on September 29, 2025, when Reservoir finalized a partnership arrangement with World Liberty Financial. This collaboration facilitated the creation and cancellation of rUSD directly matching World Liberty Financial's USD1 stablecoin on a uniform value basis. The capability was made accessible through the Reservoir platform, providing cost-free, multi-chain functionality. Reservoir communicated, "Reservoir stands among the initial stablecoin protocols to deliver this capability for USD1 participants." The partnership broadened the collateral foundation supporting Reservoir and generated expanded possibilities for both rUSD and derivative instruments like srUSD.
Reservoir srUSD functionality relies on integrated technical elements and operational procedures embedded within the Reservoir protocol. These frameworks regulate creation, termination, interest allocation, and security arrangements.
Core Architecture
A dedicated protocol subsystem called the Savings Module handles srUSD administration and operations. This module coordinates creation and redemption workflows. Users generate srUSD by transferring the protocol's base stablecoin, rUSD, to the module. The arrangement aims for accessibility, permitting effortless conversion between a non-interest-bearing stablecoin and an interest-bearing version.
Converting srUSD back to rUSD operates instantaneously, granting participants rapid withdrawal capability. This quick conversion depends on existing liquidity in a complementary system called the Peg Stability Module (PSM). The PSM preserves rUSD value consistency and facilitates direct conversion between rUSD and authorized collateral options, guaranteeing sufficient capital exists for srUSD withdrawals.
Yield Generation and Collateral
As of October 20, 2025, Reservoir srUSD (SRUSD) exhibits the following token characteristics and market information. The token operates across both Ethereum and Berachain ecosystems.
SRUSD exchanges occur on decentralized trading venues, with Uniswap V3 (Ethereum) representing the dominant exchange. The predominant exchange combination involves SRUSD paired with USDC.
The advancement and application of Reservoir and srUSD depend on cooperative arrangements and linkages with participants across the decentralized finance sector.
FAQ
Reservoir srUSD is a yield-generating stablecoin issued by the Reservoir protocol that enables holders to accumulate interest on their stablecoin balances. Supported by a diversified collection of digital and real-world assets, it functions on the Ethereum network with additional availability on other blockchains.
Reservoir srUSD Stablecoin maintains its dollar peg through over-collateralised crypto assets or fiat reserves. The specific mechanism — whether over-collateralisation, algorithmic rebasing, or fiat-backed reserves — determines its stability profile, capital efficiency, and risk characteristics. Full details are available in the protocol's documentation.
That depends on the type of stablecoin. Fiat-backed stablecoins hold cash or cash-equivalent reserves at a 1:1 ratio. Crypto-backed stablecoins like DAI are over-collateralised and hold more collateral than the stablecoins issued. Algorithmic stablecoins may not hold 1:1 reserves at all times. Check Reservoir srUSD Stablecoin's official documentation for the exact backing structure.
Reservoir srUSD Stablecoin's collateral composition is defined in its smart contract parameters and may include cryptocurrencies, tokenised real-world assets, or fiat-equivalent deposits. The current collateral breakdown is typically published in real time via the protocol's dashboard or on-chain analytics tools such as DeFiLlama.
No stablecoin is entirely risk-free. Reservoir srUSD Stablecoin carries risks specific to its peg mechanism, including collateral volatility, oracle failure, smart contract vulnerabilities, and regulatory action against its issuer or backing assets. Reviewing audit reports and understanding the peg mechanism is essential before holding significant amounts.
Risks include de-pegging events (where the stablecoin trades above or below $1), smart contract exploits, collateral liquidations, issuer insolvency (for fiat-backed variants), and regulatory restrictions. Historical de-peg events in the stablecoin market — including the collapse of TerraUSD in 2022 — underscore the importance of understanding each stablecoin's mechanism before committing capital.
Reservoir srUSD Stablecoin can typically be acquired on decentralised exchanges (such as Uniswap or Curve Finance) or centralised exchanges. Some stablecoins can also be minted directly through the issuing protocol by depositing the required collateral. Check CoinMarketCap or CoinGecko for a list of exchanges listing Reservoir srUSD Stablecoin.
Reservoir srUSD Stablecoin can be deposited into lending protocols such as Aave or Compound, supplied to DEX liquidity pools on Uniswap or Curve, or staked in the issuing protocol for protocol rewards. Yield rates fluctuate based on supply and demand. Always compare rates on aggregators like DeFiLlama's yield tracker before committing funds.
Reservoir srUSD Stablecoin was created by a team of blockchain developers or a decentralised protocol. Some stablecoins are issued by regulated companies (Circle issues USDC; Tether issues USDT), while others such as DAI are governed by a decentralised autonomous organisation (MakerDAO). Check the official Reservoir srUSD Stablecoin website for publisher information.
USDT (Tether) and USDC (Circle) are the two largest stablecoins by market capitalisation and are both fiat-backed. Reservoir srUSD Stablecoin may differ in its collateral type, decentralisation level, transparency, supported chains, and regulatory status. Decentralised stablecoins like DAI or USDe offer censorship resistance that fiat-backed alternatives cannot provide, at the cost of greater complexity and different risk exposures.
