The heady days of triple-digit annual percentage yields on Ethereum-based DeFi protocols came to a brutal end in June 2022. The collapse of Celsius Network and the cascading contagion that followed erased billions of dollars in total value locked across decentralized finance platforms, marking what many analysts called the definitive end of the yield farming era that had defined DeFi since the summer of 2020. With Bitcoin trading at $26,762 and Ethereum at $1,445, the entire cryptocurrency market was in freefall — and DeFi was not spared.
TL;DR
- Celsius Network froze withdrawals on June 12, 2022, triggering a DeFi contagion
- Bitcoin dropped to $26,762 and Ethereum to $1,445 as the selloff intensified
- DeFi total value locked plummeted as cascading liquidations swept through lending protocols
- Major tokens like SOL (-20% weekly), AVAX (-28% weekly), and ADA (-12% weekly) suffered steep losses
- The yield farming model that defined 2020-2021 DeFi was fundamentally discredited
The Golden Age of DeFi Yields
From the summer of 2020 through late 2021, DeFi yield farming was the hottest trend in cryptocurrency. Protocols like Compound, Aave, Curve, and Yearn Finance offered users extraordinary returns for providing liquidity to decentralized lending and trading pools. Annual percentage yields routinely exceeded 100%, and in some cases reached into the thousands of percent, driven by token incentives and liquidity mining programs.
Total value locked in DeFi protocols surged from less than $1 billion in early 2020 to a peak of over $180 billion by November 2021, coinciding with Bitcoin’s all-time high near $69,000. The promise was intoxicating: deposit your crypto, earn massive yields, and withdraw anytime. It seemed too good to be true. As it turned out, much of it was.
The Unraveling Begins
The first crack appeared in May 2022 with the catastrophic collapse of the Terra ecosystem. Terra’s algorithmic stablecoin UST lost its dollar peg, and the associated LUNA token went from $60 to effectively zero in a matter of days, wiping out approximately $40 billion in value. The fallout from Terra exposed the interconnectedness and fragility of the crypto lending ecosystem.
Celsius Network was particularly exposed. The platform had deployed significant user funds into various DeFi protocols and staking strategies, including positions in stETH (Lido’s liquid staked Ethereum). When stETH began depegging from ETH in early June 2022, trading at an increasing discount to the underlying asset, Celsius’s positions came under severe pressure. The company had also reportedly suffered significant losses from the Terra collapse.
The June 12 Freeze and Its Aftermath
On June 12, 2022, Celsius Network announced it was freezing all withdrawals, swaps, and transfers, citing “extreme market conditions.” The platform held nearly $12 billion in assets under management, and the freeze left hundreds of thousands of users unable to access their funds. Alex Mashinsky, Celsius’s founder and CEO, had previously been one of the most vocal promoters of the “unbank yourself” movement, encouraging users to move their savings from traditional banks to Celsius to earn high yields.
The impact on the broader DeFi ecosystem was immediate and severe. As the market crashed, lending protocols across Ethereum experienced massive liquidation events. Borrowers who had used their crypto holdings as collateral to take out loans faced margin calls as the value of their collateral plummeted. Liquidation bots — automated programs designed to liquidate underwater positions — went into overdrive.
The Numbers Tell the Story
The price data from June 12, 2022, reveals the extent of the damage. Bitcoin was down 5.6% in 24 hours and 10.5% over the week. Ethereum had fallen 5.5% daily and nearly 20% weekly. Solana was off 20% over seven days, Avalanche had plunged 28%, and even major stablecoins showed signs of stress. The total cryptocurrency market cap had contracted by hundreds of billions of dollars from its peak.
For DeFi protocols specifically, the damage was measured in total value locked. As asset prices fell, the dollar value of deposits on platforms like Aave, Compound, MakerDAO, and Curve Finance declined precipitously. The liquidation cascade created a vicious cycle: falling prices triggered liquidations, which forced selling, which drove prices even lower, triggering more liquidations.
What Went Wrong With Yield Farming
The fundamental problem with the yield farming model that emerged in 2020-2021 was sustainability. Many of the extraordinary yields offered by DeFi protocols were not generated by genuine economic activity but were instead subsidized by token emissions. Protocols would print their own governance tokens and distribute them to liquidity providers, creating the illusion of sustainable high yields while inflating the token supply.
When token prices crashed, the real yields vanished. Users who had been earning 50% or 100% APY found that the tokens they were earning had lost 80% or 90% of their value. The yields were real in token terms but largely illusory in dollar terms. Celsius and similar platforms amplified this problem by layering additional risk on top — re-hypothecating user assets, taking on leveraged positions, and deploying funds into risky DeFi strategies without adequate risk management.
The DeFi Protocols That Survived
Not all DeFi protocols suffered equally during the June 2022 crisis. The ones that fared best shared common characteristics: transparent smart contracts, conservative risk parameters, and no reliance on token emissions to sustain yields. Aave and Compound, the two largest decentralized lending protocols, continued operating throughout the crisis. Their automated liquidation mechanisms worked as designed, and neither protocol experienced significant bad debt.
MakerDAO, the protocol behind the DAI stablecoin, also weathered the storm. Despite the extreme market volatility, DAI maintained its dollar peg, demonstrating the resilience of overcollateralized stablecoin designs. The contrast between DAI’s stability and the collapse of algorithmic stablecoins like UST was stark and instructive.
Why This Matters
The June 2022 DeFi crisis was not just a market crash — it was a reckoning. It exposed the unsustainable economics of yield farming, the dangers of centralized crypto lending, and the risks of opacity in financial products. The era of easy money in DeFi was over, replaced by a more sober understanding that sustainable yields require genuine economic value creation. The protocols that survived — Aave, Compound, MakerDAO, Curve — did so because they were built on sound principles: transparency, overcollateralization, and automated risk management. Going forward, the DeFi industry would need to rebuild trust through better risk management, more realistic yield expectations, and a commitment to the core principles of decentralization and transparency that made DeFi compelling in the first place.

triple digit apys were obviously unsustainable. any protocol offering 500% on a stablecoin pool was begging for a death spiral
the yield farming era gave us solid tech built on terrible incentive structures. still using aave and uniswap though, the survivors earned it
aave and uni survived because they had actual product market fit, not just yield incentives. the tech was always fine, the ponzi wrappers around it werent
500% apy on stablecoins was obviously ponzi economics. the real question is why anyone with basic math skills thought it was sustainable
500% on stablecoins and the yield came from… other people depositing stablecoins. it was a circle of yield with nothing generating actual revenue underneath
people with basic math also deposited because leaving early felt like walking out of a casino while the machines still paid. the math was never the hard part
yield_curmudgeon calling it obvious in hindsight is easy. when Celsius was paying 8% on BTC everyone including your mom was depositing
yield_curmudgeon calling 500 pct apy obviously ponzi in hindsight is easy. during the moment everyone including cetacean was depositing. the social proof was overwhelming
sol -20%, avax -28% in a single week. june 2022 was absolutely brutal across the board, not just defi
AVAX -28% in a week and people were still calling dips. june 2022 broke a lot of people who thought sub-1000 ETH was impossible
AVAX at -28% weekly and people were still doing the stablecoin LP shuffle hoping for recovery. the copium was insane
june 2022 was when i stopped chasing apy and started reading actual protocol revenue. changed my entire approach to defi
rustbucket_ same. june 2022 was the reset. stopped chasing APY and started looking at protocol fees and token burns
rustbucket_ switching from APY chasing to protocol revenue analysis was the correct pivot. june 2022 rekt the gamblers but educated the survivors
The Celsius collapse wiped out $4.2B in TVL virtually overnight. What people forget is that the cascading liquidations weren’t just in DeFi—they dragged down entire token ecosystems with 20-40% weekly drops across the board.
June 2022 was brutal for NFTs too. Floor prices on major collections dropped 60-80% as the broader crypto selloff washed over everything. The yield farming hype had made people forget about actual utility and fundamentals.
Celsius offering 8% on BTC deposits should have been the loudest alarm. where was the yield coming from? oh right, anchor protocol and 3AC
celsius_baggage_ 8% on BTC was obviously lent out to generate yield in riskier places. classic fractional reserve with crypto rails. people trusted the brand instead of reading the proof of reserves
the SOL at -20% and AVAX at -28% weekly numbers brought back memories. june 2022 was when the last bit of hopium died
BTC at 26K and ETH at 1445 during the celsius unwind. people forget how fast it cascaded. one week you are earning 8 pct on BTC the next your funds are frozen
That 8 pct on BTC line is the part I keep returning to. Celsius paid interest deposits could never legitimately earn. The freeze on June 12 should have ended the yield obsession for good.
8 percent on BTC deposits should have been the math test nobody passed. the June 12 freeze ended the yield era and half this industry still has amnesia about it
triple digit apy was only ever sustainable while new deposits paid the old ones. anchor promising 19.5 pct on UST was the tell, celsius just repackaged it behind a mobile app
anchor at 19.5 was the free option everyone priced as risk free. once the reserve top ups went public the exit was already jammed
the reserve top ups were the bank run starting in slow motion. everyone watched it happen over weeks and still left the exit for the same afternoon
ust_bagholder the reserve top ups were public for weeks before the depeg. the info was right there, the 19.5 was just louder
