In the fast-moving world of decentralized finance, stability is more than a promise—it’s a design challenge. When market turbulence strikes, not all stablecoins respond equally. The recent depegging of USDC in March 2025 laid bare the vulnerabilities in even the most trusted digital dollar projects. Yet amid the chaos, eUSD, an asset-backed stablecoin built on Reserve Protocol, stood firm—demonstrating a new benchmark for reliability in crypto.
How did eUSD maintain its integrity while its underlying collateral faltered? The answer lies in a sophisticated blend of overcollateralization, governance safeguards, and automated risk response—core principles embedded in the architecture of RTokens, the token standard powering eUSD.
The USDC Depeg: A Crisis of Confidence and Liquidity
On March 11, 2025, Circle, the issuer of USD Coin (USDC), disclosed that $3.3 billion of its $40 billion reserve assets were temporarily inaccessible due to the collapse of Silicon Valley Bank (SVB). The news sent shockwaves across crypto markets, triggering a rapid sell-off.
USDC, which had long maintained a 1:1 peg to the U.S. dollar, dropped to as low as $0.87—a devaluation of over 13%. While USDC is backed by cash and short-term U.S. Treasury bonds, a significant portion of its cash reserves was held at SVB, a bank that had heavily invested in long-dated mortgage-backed securities.

As the Federal Reserve raised interest rates throughout 2024 and into 2025, the market value of these securities eroded. When SVB was forced to liquidate $21 billion in assets at a $1.8 billion loss, panic spread among its depositors—primarily tech startups with balances exceeding the FDIC insurance limit of $250,000. A classic bank run ensued.
California regulators shut down SVB on March 10. The FDIC stepped in, but uncertainty around the availability of Circle’s reserves sparked a crisis of trust. Since USDC’s redeemability was partially compromised, traders lost confidence—proving once again that even centralized stablecoins are only as strong as their weakest link.
How eUSD Stood Strong: The Power of Smart Design
eUSD, created by MobileCoin using Reserve Protocol, is classified as an RToken—a decentralized, user-configurable stablecoin backed by a basket of assets. At the time of the SVB collapse, 50% of eUSD’s backing consisted of USDC derivatives (cUSDC and aUSDC). Despite this heavy exposure, eUSD never wavered from its peg.
The reason? Proactive risk mitigation baked into the protocol’s code.
Key Features of RTokens That Saved eUSD
- Dynamic Collateral Baskets: RTokens allow creators to define and update their collateral composition through governance.
- Overcollateralization via Staked RSR: Reserve Rights (RSR) token holders can stake their tokens to back an RToken, acting as first-loss capital during defaults.
- Automated Default Response: Oracles monitor price feeds; if a collateral asset depegs beyond a threshold, a 24-hour countdown begins toward default declaration.
Here’s how it played out:
- March 11 – Early Morning: Oracles detected USDC trading below $0.995. The protocol flagged cUSDC and aUSDC as “at risk,” initiating a 24-hour grace period.
- March 12 – Midday: With USDC still depegged, Reserve Protocol officially declared a default. It triggered on-chain auctions to liquidate the affected USDC derivatives.
- Collateral Swap: The protocol sold cUSDC and aUSDC at an average rate of $0.955, converting proceeds into USDT—the predefined emergency collateral.
- Backstop Activation: Post-auction, eUSD remained 98% collateralized. The missing 2% would be covered by selling staked RSR tokens.
A minor technical discrepancy—less than one-millionth of a token—delayed the final RSR sale. For safety, the protocol paused trading until governance approval, which requires a 7-day voting cycle. While this introduced a short delay, it ensured no losses occurred.
“The system worked exactly as intended: protect users first, resolve risks transparently, and never compromise on security.”

This incident proved that decentralized risk management can outperform centralized response times, especially when human panic amplifies market volatility.
Why eUSD Represents the Future of Stable Value
While traditional stablecoins rely on trust in institutions and custodians, eUSD shifts the trust layer to code and economic incentives. Its resilience wasn’t luck—it was engineered.
Core Advantages of eUSD and RTokens:
- Transparent Risk Response: Every step—from depeg detection to auction execution—is visible and verifiable on-chain.
- No Single Point of Failure: Diversified collateral and emergency mechanisms reduce reliance on any one bank or asset.
- User-Centric Governance: Communities can adapt collateral strategies in response to macro risks.
- Passive Protection for Holders: Users don’t need to act during crises; the protocol defends their value automatically.

Compare this to USDC holders during the SVB crisis: many sold at a loss out of fear, lacking visibility into recovery timelines. In contrast, eUSD holders observed real-time protocol actions—no speculation, no rumors, just data.
Frequently Asked Questions (FAQ)
Q: What is eUSD?
A: eUSD is an asset-backed stablecoin built on Reserve Protocol using the RToken framework. It maintains its peg through diversified collateral and overcollateralization via staked RSR tokens.
Q: How is eUSD different from USDC?
A: Unlike USDC—a centralized stablecoin backed primarily by cash and Treasuries—eUSD is decentralized, governed by smart contracts, and includes automatic risk response mechanisms like collateral swaps and staking backstops.
Q: Did eUSD lose its peg during the USDC depeg?
A: No. Despite holding 50% USDC derivatives, eUSD remained stable thanks to its protocol-level safeguards, including timely liquidation and emergency collateral conversion.
Q: What role does RSR play in eUSD’s stability?
A: RSR token holders stake their assets to support eUSD, acting as first-loss capital during collateral defaults. In return, they earn yield generated by eUSD’s reserve assets.
Q: Can anyone create an RToken like eUSD?
A: Yes. RTokens are permissionless—any team or community can launch one by defining its collateral basket and governance rules through Reserve Protocol.
Q: Is eUSD fully backed after the SVB event?
A: Yes. After selling defaulted USDC derivatives for USDT and preparing to auction staked RSR for the remaining gap, eUSD will return to full collateralization once governance approves the final step.
The Bigger Picture: Redefining Stability in Crypto
The SVB incident wasn’t just a test for USDC—it was a wake-up call for the entire stablecoin ecosystem. Trust in centralized custodians can evaporate overnight. Meanwhile, protocols like Reserve Protocol are proving that decentralized, rule-based systems can offer superior resilience.
eUSD’s performance underscores a growing trend: users are shifting toward stablecoins that offer not just peg stability, but transparency, automation, and user protection by design.
As regulatory scrutiny increases and macroeconomic risks persist, assets like eUSD may become preferred tools for preserving value—especially for those who prioritize decentralization without sacrificing reliability.

While RTokens are still emerging, their real-world performance during crises validates their potential. In an era where digital dollars must withstand both market storms and institutional failures, eUSD isn’t just surviving—it’s setting a new standard.
