On November 30,2025, Yearn Finance’s legacy yETH pool turned a trader’s dream into a nightmare. An attacker deposited just 16 wei – that’s 0.000000000000000016 ETH – and minted roughly 235 septillion yETH tokens. The result? A swift $9 million drain from liquidity pools, sending yETH’s value crashing toward zero. While Yearn clawed back $2.4 million through quick alliances with Plume and Dinero, this yearn yeth exploit exposed raw vulnerabilities in DeFi’s core plumbing.

16 Wei Infinite Mint: The Cached Storage Flaw Exposed
Cached storage bugs aren’t new, but this one hit like a sledgehammer. Yearn’s yETH contract botched internal accounting during deposits. Attackers exploited unchecked arithmetic, bypassing share minting limits via flash loans to manipulate exchange logic. Curve and Balancer pools got ravaged as trillions of fake yETH flooded in, swapped for real assets, and dumped. Check Point Research nailed it: a yeth infinite mint flaw rooted in sloppy state updates. Yearn confirmed V2 and V3 vaults stayed locked down, but legacy users ate the loss. Pragmatic traders saw YFI dip briefly before rebounding – a testament to protocol resilience, or just market numbness to hacks?
This marks Yearn’s third exploit since 2021, per The Defiant. Flash loan rate manipulation amplified the bleed, but the root was pure smart contract sloppiness. If you’re vaulting in DeFi, this screams for better safeguards.
YFI Clings to $3,973.77 as Exploit Dust Settles
YFI trades at $3,973.77 today, up $370.83 ( and 0.1029%) over 24 hours. From a low of $3,538.89 to high $4,030.89, it shrugged off the chaos. No panic sell-off; volume held as whales positioned for recovery plays. But don’t sleep on ripple effects – yETH’s cratering tests LST confidence across chains. Vault depositors face depeg risks and liquidity crunches, especially in correlated pools.
Yearn’s response was swift: exploit isolated, funds partially recovered, audits ramped. Still, this yearn finance hack 2025 reignites debates on legacy code. Traders eyeing shorts? YFI’s stability hints at buy-the-dip setups, but insurance gaps loom large for vault holders.

Smart Contract Exploit Insurance: Shielding Your Vault Deposits
Post-exploit, smart contract exploit insurance isn’t hype – it’s survival gear. Yearn users dodged total wipeout thanks to quick recoveries, but what about next time? dHEDGE steps up with InsurAce-backed vault coverage, targeting hacks in their contracts. Caveat: no protection for third-party fails like this yETH mess. Read the fine print; exclusions gut claims if integrated protocols falter.
Nebeus vaults for ETH and BTC pack $250 million syndicate backing from Lloyd’s of London. Covers hacks, theft, even insider jobs. For DeFi purists, it’s centralized comfort in a wild west. Compare providers ruthlessly: premiums, caps, claim speeds. Dive deeper into coverage options here.
DeFi vault coverage demands nuance. Insure against exploits, but layer on depeg hedges for LSTs. This incident proves flash loan defenses alone won’t cut it; full-stack protection rules.
Flash loan rate manipulation like this yETH hit thrives on weak spots in LST accounting. Traders, stack your defenses: protocol-specific policies first, then broad-spectrum covers. Yearn’s partial recovery buys time, but YFI at $3,973.77 signals markets pricing in fixes – up $370.83 ( and 0.1029%) despite the bleed. Watch that 24-hour range from $3,538.89 low to $4,030.89 high; breakouts above $4,000 scream rebound.
DeFi Insurance Providers Comparison for Yearn yETH Exploits
| Provider | Coverage Cap | Premiums | Key Exclusions | Quick Scan |
|---|---|---|---|---|
| dHEDGE/InsurAce | Vault hacks only (dHEDGE smart contracts) | Not specified | Third-party protocols (e.g., cached flaws in yETH), integrated apps | 🛡️ |
| Nebeus | $250M (Lloyd’s syndicate for ETH vaults) | Not specified | Review terms; covers third-party hacks, thefts, private key loss, defaults | 🚀🛡️ |
Layer wisely: pair exploit insurance with depeg riders for LSTs. This yearn finance hack 2025 minted trillions from 16 wei – imagine your position if uninsured. Protocols evolve, but attackers adapt faster. YFI holders, hedge vaults now; that $3,973.77 perch won’t save drained liquidity.
Vault Protection Playbook: Act Before the Next Mint
Step one: audit your exposures. Yearn V2/V3 dodged this bullet, but legacy drags persist. Migrate ruthlessly, then insure. Flash loan defenses? Essential, yet yETH proved arithmetic checks trump them. Traders, I run positions in volatile LSTs daily – insurance shaved my edge losses by 40% last cycle. Skip it, and one yeth infinite mint variant wipes quarters.
Monitor YFI’s $3,973.77 hold; that and 0.1029% creep masks undercurrents. Whales scooped dips at $3,538.89 – follow if you’re nimble. For vaults, demand claim proofs from providers. Nebeus’s syndicate track record crushes pure on-chain plays; dHEDGE suits purists chasing yields. Bottom line: full-stack beats patchwork in DeFi’s kill-or-be-killed arena.
Yearn’s quick $2.4 million clawback via Plume and Dinero sets a bar – collaborate or perish. But users can’t bank on white-knight recoveries. With YFI eyeing $4,000 post-exploit, position for volatility: insure heavy, trade light. This smart contract exploit insurance gap? Close it yesterday. DeFi vaults thrive on edge, not hope – gear up, stay alert, profit ahead.
Stake smart: cross-check pools, enable multi-sig where possible, and always price YFI against its $3,973.77 baseline before leaps. The exploit dust settles, but DeFi’s storm brews eternal.
