Reservoir is a decentralized finance (DeFi) system operating on the Ethereum network that generates various stablecoins supported by a combination of blockchain assets and Real World Assets that have been tokenized (RWAs). The protocol's main offering is rUSD, with the objective of delivering a stablecoin ecosystem that is scalable, efficient, and produces yield returns.
Overview
Reservoir was created to tackle what its founders call the "Stablecoin Pentlemma," describing criteria that modern stablecoins must satisfy: decentralization, price stability, efficient capital use, strong utility, and sufficient decentralization. The protocol operates similarly to a blockchain-based bank, employing a smart contract system for asset and liability oversight to deliver products with yield while preserving price stability. By including RWAs, including tokenized U.S. Treasury Bills, within its backing assets, Reservoir seeks to create more reliable and long-term yield that shows less connection to cryptocurrency market swings.
Fortunafi, an RWA tokenization organization founded in 2020, developed Reservoir. Although created by Fortunafi, Reservoir operates as a distinct organization to concentrate on stablecoins and yield-generating solutions. The protocol's goal is to link RWA tokenization with DeFi services to enable new asset types to enter the market. Its primary audience encompasses stablecoin holders wanting yield on their holdings, cryptocurrency holders aiming to extract value from their positions, and corporate entities seeking streamlined entry to blockchain markets.
History
Reservoir's creation originated from Fortunafi's research, an organization established in 2020 with expertise in bringing RWAs into DeFi applications at scale. The Reservoir protocol was formally introduced by Fortunafi on May 29, 2024, with plans to establish it as an independent organization in June 2024.
The Ethereum mainnet received the protocol launch on August 22, 2024, accompanied by the introduction of a "Reservoir Points Reward System" designed to drive user adoption. Following this initial release, the protocol broadened its offerings by debuting srUSD, a stablecoin generating yield, on November 7, 2024. On November 8, 2024, Reservoir revealed cooperation with Morpho and Steakhouse to establish a dedicated rUSD vault on Morpho's platform, enabling users to obtain and borrow the stablecoin.
During 2025, the protocol broadened its services and connectivity across chains. A declaration regarding the launch of its native token came on June 2, 2025, later confirmed as DAM on July 24, 2025. A crucial advancement took place on September 8, 2025, when OneStable protocol launched—a multi-chain minting solution created with Enso, Stargate, and LayerZero. In late September on the 29th, Reservoir declared an alignment with World Liberty Financial, permitting users to directly produce and exchange rUSD utilizing the USD1 asset with 1:1 conversion.
Technology and Architecture
Reservoir functions as a Collateralized Debt Position (CDP) system, enabling participants to provide supported collateral to produce its stablecoins. The design incorporates segregated lending pools and risk management mechanisms to reduce exposure while generating income from its varied collateral holdings.
Token Ecosystem
The system comprises several tokens created to satisfy various uses, including stable transfers and yield production.
Key Smart Contract Modules
Multiple fundamental smart contract systems oversee the protocol's equilibrium and capabilities.
- rUSD: The primary stablecoin within the system, engineered to be over-collateralized, resistant to control, and usable throughout the DeFi landscape.
- srUSD (Savings rUSD): A liquid, yield-producing asset representing user contributions to Reservoir's savings layer. Participants receive earnings from the protocol's supported assets' performance.
- wsrUSD (Wrapped Savings rUSD): A version of srUSD designed for interoperability with other DeFi platforms that need particular token specifications.
- trUSD (Term rUSD): A duration-locked, yield-producing token intended for participants agreeing to lock resources for set durations in return for increased potential earnings.
- DAM Token: The protocol's forthcoming proprietary token. Its intended purposes, including participation in decisions or staking mechanisms, remained undefined at public announcement.
- Peg Stability Module (PSM): A system critical to keeping rUSD aligned with the U.S. dollar value. It enables users to exchange rUSD for other permitted stablecoins, such as USDC or USD1, maintaining a 1:1 rate without execution slippage, offering an arbitrage mechanism to support the peg.
- Credit Enforcer: An automated smart contract functioning as the protocol's risk controller. It enforces borrowing and solvency guidelines, restricts total rUSD and trUSD supply per governance decisions, and mechanically applies extra funds into yield tactics.
- Proof of Reserves: An integrated accounting system showing the protocol's financial standing in real-time on-chain. It grants openness by letting anyone examine the protocol's backed status, financial health, and available resources, refreshed with each transaction.
- Asset Adapters: Configurable smart contract implementations allowing the protocol to incorporate and supervise many kinds of blockchain and physical world collateral supporting the system's stablecoins.
Tokenomics
In October 2025, the Reservoir network included two principal active tokens, rUSD and srUSD, with joint market value near $397 million.
rUSD
srUSD
- Type: Dollar-pegged Stablecoin
- Maximum Supply: Unrestricted
- Blockchain Presence: rUSD operates on Ethereum, Solana, Base, Arbitrum One, BNB Smart Chain, and Avalanche.
- Type: Yield-Generating Stablecoin
- Maximum Supply: Unrestricted
- Blockchain Presence: srUSD is offered on Ethereum and Berachain.
Partnerships and Integrations
Reservoir has built important collaborative agreements to increase functionality and expansion.
- Fortunafi: As the founding organization, Fortunafi maintains close ties with Reservoir. Fortunafi's tokenization services for RWAs furnish quality, yield-bearing backing assets for the Reservoir network, while Reservoir's rUSD grants usability for RWA-related transactions.
- Enso, Stargate, and LayerZero: These systems partnered with Reservoir to establish and deploy OneStable, a multi-chain minting resolution.
- World Liberty Financial: An association disclosed in September 2025 made it possible for users to generate and redeem rUSD through World Liberty Financial's USD1 stablecoin directly, improving rUSD's market depth and user access.
- Morpho and Steakhouse: Through this collaboration, a specialized rUSD position was constructed within Morpho's lending framework, enabling users to acquire credit through collateral or manufacture rUSD inside the Morpho ecosystem.
Frequently Asked Questions
What is Reservoir?
Reservoir is a decentralized stablecoin system built on Ethereum that creates the rUSD stablecoin, backed by a diversified portfolio of blockchain-based assets and tokenized Real World Assets (RWAs). The protocol functions as...
How does Reservoir work?
Reservoir operates through smart contracts deployed on the Ethereum blockchain. Users interact directly with the protocol via a web interface or wallet integration — no account creation or KYC is required. All operations are settled on-chain and are publicly verifiable.
Is Reservoir safe to use?
Reservoir has undergone smart contract audits and is among the more established protocols in DeFi. However, all DeFi protocols carry inherent risks including smart contract vulnerabilities, oracle failures, and liquidation risk. Users should only commit funds they can afford to lose and review the protocol's audit reports before participating.
What blockchain is Reservoir built on?
Reservoir is primarily deployed on Ethereum. Many leading DeFi protocols are also expanding to Layer-2 networks such as Arbitrum, Optimism, and Base to reduce transaction costs and improve throughput.
What are the risks of using Reservoir?
Key risks include smart contract exploits, governance attacks, oracle manipulation, liquidity crises, and regulatory uncertainty. DeFi protocols are uninsured — losses from exploits are typically not recoverable. Always review audits and understand the mechanism before depositing funds.
How do I get started with Reservoir?
To use Reservoir, you need a self-custody wallet (such as MetaMask or Rabby), ETH for gas fees, and the relevant tokens for the action you want to perform. Visit the official protocol interface, connect your wallet, and follow the on-screen steps. Start with a small amount to familiarise yourself with the UX.
What token does Reservoir use?
Reservoir typically has a native governance token that allows holders to vote on protocol parameters, fee structures, and treasury allocations. Check the protocol's documentation for the current token ticker, total supply, and distribution schedule.
Who created Reservoir?
Reservoir was founded by a team of blockchain developers and DeFi researchers. The protocol is typically governed by a decentralised autonomous organisation (DAO), meaning ongoing development and parameter changes are decided collectively by token holders rather than a central company.
What is the total value locked (TVL) in Reservoir?
Reservoir's TVL fluctuates with market conditions and can be tracked in real time on DeFiLlama (defillama.com). TVL measures the total value of assets deposited into the protocol and is a key indicator of user confidence and liquidity depth.
How does Reservoir compare to other DeFi protocols?
Reservoir is differentiated by its specific mechanism, fee structure, and supported assets. Comparing protocols should include factors such as audited security posture, capital efficiency, governance maturity, cross-chain availability, and historical uptime. DeFiLlama and Dune Analytics provide side-by-side comparative data.
