The fallout from the KelpDAO hack has spilled into the broader decentralized finance ecosystem, driving a notable contraction in stablecoin balances over a seven-day period. According to the source material, the stablecoin sector shed roughly $892.8 million during the week as users unwound DeFi positions and moved capital in response to heightened protocol risk.
Even with that outflow, the market did not collapse. Total stablecoin capitalization remained at a substantial $320.65 billion, suggesting that this was less a full-scale exit from dollar-pegged crypto assets and more a targeted repositioning within the sector. In other words, capital appears to have rotated away from structures perceived as more vulnerable while concentrating in the most liquid and established issuers.
USDT Strengthens as Capital Seeks Relative Safety
The clearest beneficiary of this shift was Tether’s USDT, which retained its commanding lead in the market. USDT stood at $189.78 billion in market capitalization and accounted for 59.19% of the total stablecoin market. The report notes that USDT actually rose 1.55% over the week, adding about $2.89 billion in value even as the broader sector experienced net outflows.
That performance reinforces a familiar pattern in crypto stress events: when confidence in DeFi mechanisms weakens, users often prefer the largest and most battle-tested stablecoin for liquidity and settlement. Rather than abandoning stablecoins altogether, market participants frequently consolidate exposure into assets that are widely accepted across exchanges, protocols, and trading venues.
Circle’s USDC, the second-largest stablecoin, moved in the opposite direction. Its market capitalization was reported at $77.79 billion, but it declined 1.01% during the week. Between April 19 and April 26, that translated into a reduction of roughly $794 million. While the drop was far less severe than some of the more DeFi-linked products, it still reflected a risk-off environment across the sector.
DeFi Stress Spreads Beyond a Single Protocol
The article describes the KelpDAO incident as a catalyst for a broader DeFi contraction. Total value locked across decentralized finance reportedly fell sharply within days, and the impact extended to major protocols including Aave. As users rushed to reduce leverage and close positions, stablecoins became both the preferred exit route and the measuring stick for how capital was being redistributed.
This is a key distinction. The market data did not show indiscriminate panic across every major stablecoin. Instead, it pointed to deliberate capital movement. Some stablecoins lost supply, some held relatively firm, and a few posted gains. That pattern suggests investors were actively reassessing structural risk, not simply fleeing everything at once.
Among the larger names, USDS — associated with the rebranded Sky ecosystem, formerly MakerDAO — recorded a market capitalization of $8.27 billion and fell 1.89% over the week. Based on the figures in the source, that implies a reduction of about $159 million in value during the period.
Meanwhile, DAI, another stablecoin from the same ecosystem, moved higher. It held a market capitalization of $4.67 billion and posted a 1.55% weekly increase. The fact that DAI rose while other assets weakened indicates that stablecoin performance during this episode was highly differentiated and dependent on market perception, liquidity profile, and structural design.
The fifth-largest stablecoin in the ranking cited by the report was USD1 from World Liberty Financial. It reached a market capitalization of $4.39 billion and delivered the strongest weekly increase among the major stablecoins, gaining 4.34%. That made USD1 one of the few notable winners during an otherwise defensive week for the sector.
USDe Records the Sharpest Contraction
The most dramatic move came from Ethena’s USDe, which emerged as the leading casualty of the week’s deleveraging. The report states that USDe fell 34.39%, bringing its market capitalization down to $3.82 billion. More than $2 billion flowed out of USDe during the week as the KelpDAO situation unfolded.
This decline is especially significant because it highlights how quickly market confidence can deteriorate for stablecoin structures that are closely tied to complex DeFi strategies or perceived mechanism risk. While the report does not claim that USDe itself was the source of the hack, the market reaction suggests that investors were broadly reassessing risk in products linked to more intricate crypto-native financial engineering.
PayPal USD (PYUSD) also contracted sharply, falling 16.06% to a market capitalization of $3.445 billion. USDG declined 5.71% to $1.114 billion, while FDUSD slipped 1.46% to $2.34 billion. Other stablecoins such as FRAX and GUSD likewise posted seven-day declines, according to the report.
What the Numbers Suggest About Market Sentiment
The weekly data points to a market still processing shock rather than returning to equilibrium. The source explicitly frames the outflow not as random capital flight, but as a selective migration toward stronger issuers and away from more fragile structures. That interpretation is consistent with the divergence among top stablecoins: the largest incumbent expanded, some mainstream assets slipped modestly, and several risk-sensitive products suffered deep contractions.
In practical terms, this means trust remains the central variable. Stablecoins depend not only on peg maintenance, but also on confidence in redemption pathways, collateral arrangements, protocol integrations, and the resilience of associated DeFi infrastructure. When a security incident undermines that confidence, supply can contract rapidly even if the broader stablecoin category remains large.
The report argues that the next phase for the market will depend less on short-term price movement and more on whether confidence in core DeFi mechanisms can be restored. If users remain unconvinced that protocol-level risks are contained, capital may continue concentrating in dominant names such as USDT while products seen as structurally exposed could face further shrinkage.
For now, the headline takeaway is straightforward: the KelpDAO exploit triggered a meaningful DeFi unwind, the stablecoin market lost nearly $892 million in a week, and the redistribution of capital favored scale, liquidity, and perceived resilience over experimentation. The sector remains enormous at more than $320 billion, but recent flows show that under stress, not all stablecoins are treated equally.
