复盘 Venus THE 攻击：如何在瞬间窗口中获利？
复盘 Venus THE 攻击：如何在瞬间窗口中获利？
Editor’s note: On March 15, 2026 (US date), abnormal activity hit the THE market on Venus Protocol, one of the largest lending protocols on BNB Chain. The token printed a brief “wick” (a rapid spike) of roughly +116% to ~$0.60, then quickly retraced over 60%. Venus stated it was actively investigating the abnormal activity around the THE pool and took precautionary steps to reduce further impact. This post is an original, educational recap inspired by trader Weilin (William) Li’s reflection (“how I profited”)—with a focus on mechanics, risk, and what users should learn, not on encouraging exploitation.
What happened: a fast oracle / liquidity shock in a lending market
Events like the Venus THE incident typically combine three ingredients:
- Thin spot liquidity for the collateral asset (THE) at a critical moment
- A lending market that temporarily accepts that spot price (directly or indirectly) for collateral valuation
- A “single-block” or near-instant execution window where collateral value looks high before markets (and liquidators) fully react
In practice, this creates a short-lived mismatch between:
- On-chain spot price (can be pushed by aggressive buys, low liquidity, or routing quirks)
- Oracle / reference price used by the lending protocol (often designed to resist manipulation, but not always immune to extreme microstructure events)
If you want to understand how liquidations propagate once a position becomes unhealthy, start with Venus’s own documentation on the liquidation process: Venus liquidation guide.
Why the “instant window” exists: timing is a risk surface in DeFi
DeFi lending is overcollateralized, but it’s also time-sensitive:
- A user can supply collateral and borrow against it very quickly.
- Liquidators need time and incentive to react.
- Oracles and safety modules may update on a cadence that is secure in normal conditions but still exploitable during sudden dislocations.
This is exactly why many modern protocols introduce circuit breakers and deviation checks (Venus has discussed mechanisms like a deviation sentinel concept in its v4 docs: DeviationSentinel reference).
Zooming out, oracle incidents are not new on BNB Chain money markets. Venus itself has previously documented oracle-related edge cases in isolated markets (historical example: LST Isolated Pool Oracle Incident)—a reminder that oracle design and liquidity reality must match.

“How people profited” (without exploiting): the realistic playbook is volatility capture, not magic
When traders say they “made money in the window,” most of the time it’s not because they hacked anything. It’s because they had systems ready to capture volatility and dislocations. Common (legitimate) ways traders may have profited during a wick-and-revert event include:
1) Selling into the wick (pre-positioned liquidity or limit sells)
Traders who already held THE (or had resting orders / liquidity) could sell into the spike—if they were positioned before the move. The key is that the best fills usually go to those who are already in the book, not those who chase after social media notices.
2) Mean-reversion trades after the spike (carefully sized)
A rapid wick followed by a sharp drop often triggers:
- forced deleveraging,
- liquidation cascades,
- panic selling, which can create overshoot to the downside.
Some traders profit by buying the capitulation and taking a quick rebound—while accepting that catching falling knives is extremely dangerous.
3) Hedged basis trades (if a hedge venue exists)
Sophisticated desks may hedge directional risk elsewhere (e.g., correlated assets or structured positions). The profit comes from price convergence, not from being “right” directionally.
Important: none of these are “safe.” In DeFi, the biggest hidden cost is execution risk: slippage, MEV, paused markets, sudden parameter changes, and liquidation bots repricing faster than humans.
The real lesson for everyday users: your liquidation risk can spike faster than your notifications
If you supplied THE as collateral, borrowed against it, or provided liquidity around the event, focus on defense:
- Check your Health Factor / borrowing power and reduce leverage quickly. Venus’s leveraged-position tooling (looping / boosting) can amplify risk in exactly these moments: Venus leveraged positions guide.
- Do not assume you’ll have time to react. In fast markets, you often don’t.
- Avoid concentration in thin-liquidity collateral (especially long-tail assets) when borrowing large caps or stablecoins.
- Keep a safety buffer instead of borrowing to the maximum.
A good “2025–2026 DeFi risk trend” to internalize: lending protocols have improved UX dramatically, but speed cuts both ways—it helps you leverage in one click, and it helps liquidators unwind you just as fast.
What protocols (and risk managers) should take from this
From a protocol-design perspective, these events keep pointing to the same hard questions:
- Are caps and collateral factors appropriate for the asset’s true liquidity?
- Does the oracle reflect a market that can be moved with one routing path?
- Are there borrow / supply cooldowns or dynamic LTV adjustments during extreme deviations?
- Is there a clear, fast incident process for pausing isolated markets without freezing unrelated users?
As BNB Chain DeFi keeps scaling, these controls matter more. (BNB Chain’s own ecosystem reports highlight how dominant on-chain volumes became through 2025: BNB Chain Half-Year Report 2025 (PDF).)
A self-custody angle: why signing hygiene matters even when the bug isn’t “your wallet”
Even if an incident is “just market structure,” users still lose money through:
- rushed approvals,
- signing transactions they don’t fully understand,
- interacting with clones during chaos.
A hardware wallet can’t stop oracle volatility—but it can reduce catastrophic key-loss and phishing outcomes by keeping private keys offline and adding friction to rushed signing. If you actively use BNB Chain DeFi, OneKey is a practical option for self-custody: it’s designed to keep keys isolated while still supporting everyday on-chain workflows (swaps, lending, staking) across multiple networks.
Closing: the best “profit strategy” is being hard to liquidate
The uncomfortable truth is that most traders who chase a wick lose money. The ones who consistently survive are those who treat DeFi security and risk management as part of their edge:
- avoid thin collateral for large borrowing,
- maintain buffers,
- monitor positions like a professional,
- and keep custody secure.
In the next market shock, the most valuable “instant window” might not be a profit opportunity—it might be the few minutes you have to avoid becoming liquidity for someone else’s strategy.
