1inch TrustedVolumes Exploit: $5M Drained, White-Hat Returns $4.5M — What Leveraged DeFi Traders Must Know
Data Snapshot
Key Takeaways
- •~$5M was exploited from TrustedVolumes via an integer underflow flaw in 1inch's deprecated Fusion v1 resolver; ~$4.5M (~90%) was returned after white-hat negotiation.
- •1INCH is trading at $0.0968, already at its 24h low — 100x leveraged longs opened at the day's high ($0.0985) are near liquidation thresholds.
- •No core 1inch protocol or end-user funds were impacted; 1inch has redeployed updated contracts, which limits sustained downside.
- •Cross-market impact is minimal — ETH faces negligible pressure from 1,276 WETH liquidation; AAVE and COIN may see brief sentiment contagion but no fundamental damage.
- •The white-hat resolution sets a precedent but does NOT eliminate the DeFi legacy-contract risk — traders should monitor resolver migration to Fusion v2+ as a recovery signal.

Event Summary
According to Cointelegraph and Rekt.news, on March 5, 2026 (~6 PM UTC), a third-party market maker called TrustedVolumes was exploited for approximately $5 million via an integer underflow and callback vulnerability in a deprecated 1inch Fusion v1 resolver contract. The attacker drained ~2.4M USDC and 1,276 WETH, then — in an unusual twist — entered negotiations and returned roughly $4.5M to TrustedVolumes, retaining ~$450K as an informal bug bounty. As confirmed by 1inch's postmortem, no core protocol funds or end-user wallets were affected. 1inch has since redeployed updated contracts.
The incident is part of a broader DeFi structural reset pattern, where legacy contract debt accumulates until forcibly cleared by exploits. As detailed in our DeFi Reset 2026 guide, deprecated infrastructure remains one of the sector's most persistent tail risks.
Leverage Impact Analysis
1INCH is currently trading at $0.0968 (24h change: -1.53%, per live market data), with the 24h range between $0.0968–$0.0985 — already testing the intraday low.
For leveraged perpetual futures traders on CoinUnited.io, volatility compression is deceptive here: the tight range masks headline-driven downside risk.
- -Long scenario: A trader with 100x long 1INCH opened at $0.0985 (24h high) is already at ~1.7% drawdown. At 100x, that represents ~170% of initial margin — a position already near liquidation territory depending on margin posted.
- -Short scenario: A 50x short opened at $0.0985 targeting the $0.0850 level (historical support zone) carries a reward-to-risk profile that warrants tight stops above $0.0990, given the white-hat resolution caps catastrophic downside.
- -Key risk: Partial fund recovery ($4.5M of $5M returned) removes the worst-case sentiment shock. Funding rates on 1INCH perpetuals may normalize quickly — monitor open interest on CoinUnited.io for directional confirmation.
Cross-Market Impact
ETH/WETH: The 1,276 WETH drained (~$2.7M at time of exploit) represents minor sell pressure on Ethereum. No material price impact is expected, but it adds to the ambient negative sentiment around DeFi security.
AAVE: Aave and other DeFi lending protocols face secondary sentiment contagion. Exploits on adjacent protocols historically trigger brief TVL outflows across the sector as users reassess smart contract exposure. Monitor AAVE funding rates for signs of defensive positioning.
Coinbase (COIN): As a publicly listed crypto-adjacent equity, COIN is sensitive to DeFi security narratives that dampen retail onboarding sentiment. Impact here is minimal given the white-hat resolution, but bears watching if broader DeFi TVL outflows materialize.
Macro/Forex/Commodities: No meaningful spillover. This is a DeFi-specific event with contained resolution.
Trading Considerations
1INCH trades at $0.0968, already at its 24h low, with near-term resistance at $0.0985. The white-hat resolution is a meaningful bullish mitigant — without it, comparable DeFi exploits have historically produced 10–20% drawdowns per Rekt.news precedents. Key levels to watch: a sustained break below $0.0950 would signal continued selling pressure; a reclaim of $0.0985 with volume would suggest the event has been fully priced in.
Monitor on-chain resolver contract migration data and whether institutional market makers resume using 1inch Fusion v2 — resolver re-adoption is the clearest recovery signal. For broader DeFi context, see our DeFi Protocol Exploits resolution guide.
