The Ethereum ecosystem in July 2020 is experiencing a transformation that will define an entire era of cryptocurrency. Yield farming has exploded onto the scene, governance tokens are the hottest assets in crypto, and the launch of Yearn Finance’s YFI token has captured the imagination of a new wave of DeFi enthusiasts. On July 20, Ethereum trades at $236.19 as total value locked in DeFi protocols surges past $700 million.
TL;DR
- DeFi Summer 2020 in full swing with yield farming dominating Ethereum activity
- Yearn Finance launched YFI token in mid-July 2020, rallying from $3 to thousands within weeks
- DeFi TVL peaked at approximately $776 million on July 20, up from $17 million at the start of the year
- YFI’s “fair launch” with zero pre-mine set a new standard for token distribution
- LINK pulled back 11% to $7.24 on July 20 after a strong rally, WAVES surged 9.3%
The Birth of Yield Farming
If there is one phrase that defines the summer of 2020 in crypto, it is “yield farming.” The concept — providing liquidity to decentralized protocols in exchange for governance token rewards — turned the Ethereum ecosystem into a sprawling laboratory of financial innovation. Users could deposit assets into liquidity pools on platforms like Compound, Curve, and Balancer, earning newly minted governance tokens that often appreciated dramatically in secondary markets.
Compound’s COMP token distribution, which began in mid-June 2020, is widely credited as the spark that lit the yield farming fire. By rewarding lenders and borrowers with COMP tokens, Compound created a powerful incentive structure that attracted billions of dollars in liquidity within weeks. The model was quickly replicated across dozens of protocols, each launching their own governance tokens with varying degrees of sophistication.
Yearn Finance and the YFI Phenomenon
No project exemplifies the DeFi Summer ethos better than Yearn Finance. Created by South African developer Andre Cronje, Yearn Finance was originally launched as iEarn Finance in January 2020 — a simple yield aggregator that automatically shifted user funds between lending protocols to capture the highest returns.
In mid-July 2020, Cronje took a bold step: he launched the YFI governance token with what the community dubbed the fairest distribution in crypto history. There was no pre-mine, no investor allocation, no team reserve. YFI could only be earned by providing liquidity to Yearn’s pools. Cronje famously stated that YFI was “worth $0” — a statement that the market emphatically disagreed with.
The token launched at roughly $3 and began an extraordinary ascent. Within weeks, YFI would trade above $30,000, briefly surpassing Bitcoin’s price on a per-token basis. The rally was fueled by intense speculation, limited supply, and the narrative that YFI represented the purest expression of decentralized governance in the DeFi space.
DeFi TVL Explodes
The numbers tell a staggering story. Total value locked across DeFi protocols stood at approximately $17 million at the beginning of 2020. By July 20, that figure had surged to roughly $776 million — a growth of over 4,400% in just seven months. Ethereum-based protocols accounted for the vast majority of this growth, with Compound, MakerDAO, Aave, Synthetix, and Curve Finance leading the pack.
The explosion in TVL was driven primarily by yield farming incentives. Users deposited stablecoins, wrapped Bitcoin, and Ethereum into smart contracts, creating a self-reinforcing cycle: more TVL attracted more attention, which drove token prices higher, which attracted even more capital. Ethereum miners noticed too — data shows miners began stockpiling ETH in July 2020 for the first time, betting that the DeFi boom would push gas fees and ETH demand higher.
Market Action on July 20, 2020
The crypto markets showed mixed performance on July 20. Bitcoin held relatively steady at $9,163, down just 0.6% on Kraken. Ethereum traded at $236.19, down 1.4%. Total Kraken trading volume reached $123.4 million, in line with recent weekly averages.
Among altcoins, LINK — the year’s breakout star — experienced a sharp 11% correction to $7.24 after a week of strong gains. Despite the pullback, LINK had been one of the best-performing major assets of 2020, driven by adoption of its decentralized oracle network and partnerships across the DeFi ecosystem. WAVES bucked the trend, surging 9.3% to become the 10th most-traded asset on Kraken. XTZ dropped 7.4%, ADA fell 5.1%, and ATOM lost 7.6% in a broader altcoin cooldown.
Compound’s COMP token traded at $158.34 on July 20, down 3.1% for the day but still commanding a multi-billion dollar market capitalization. The yield farming pioneer had set the template that dozens of imitators would follow throughout the summer.
The Twitter Hack and Bitcoin’s Resilience
The week leading up to July 20 was also marked by one of the most significant security incidents in social media history. On July 15, attackers compromised at least 130 high-profile Twitter accounts — including those of Barack Obama, Joe Biden, Elon Musk, and Bill Gates — in a coordinated Bitcoin scam. The attackers managed to steal over $100,000 worth of Bitcoin, though major exchanges prevented at least $300,000 in additional losses.
Notably, the incident did not shake crypto markets. Bitcoin’s price barely reacted, and the broader narrative shifted toward the centralization risk of social media platforms rather than any inherent flaw in cryptocurrency. The consensus among analysts was that the hack was, paradoxically, good for Bitcoin — it demonstrated the resilience of the network and drew mainstream attention to digital assets.
Why This Matters
July 2020 marks the moment DeFi evolved from a niche experiment into a cultural force that would reshape the entire cryptocurrency landscape. The yield farming craze demonstrated that decentralized protocols could compete with traditional financial products for user attention and capital. More importantly, it showed that governance tokens could create powerful incentive structures — a lesson that would be applied across everything from NFTs to layer-2 networks in the years that followed.
The launch of YFI and the explosion of DeFi TVL also highlighted the creative power of Ethereum’s programmable blockchain. Developers could build and deploy entirely new financial instruments in days, with no gatekeepers and no permission required. This permissionless innovation would continue to accelerate, setting the stage for the even larger DeFi boom of 2021.
For anyone watching the crypto space in July 2020, the signals were unmistakable: Ethereum was becoming the platform of choice for financial innovation, and the DeFi movement was just getting started.

TVL went from 17M to 776M in 7 months and people still act like DeFi is a 2024 thing. the seeds were all planted that summer
YFI going from $3 to four figures in weeks broke every model people had. fair launch with zero pre-mine was the real innovation, not the yield farming itself
TVL going from 17 million to 776 million in 7 months was the craziest growth curve anyones ever seen in finance
the TVL jumping from 17M to 776M in seven months was pure speculation dressed as innovation. most of those protocols were recycled code with a token bolted on
Anders H. hard agree. everyone celebrates the TVL number but nobody mentions 80% of it was mercenary capital that vanished by september
dark_forest_ is right that 80%% of that 776M TVL was mercenary. but the 20%% that stuck around became the actual foundation of defi. yearn, aave, curve all trace back to july 2020
Andre Cronje distributing 100% of supply to the community with zero premine was unprecedented. No dev fund, no investor allocation. Pure fair launch
Andrej nailed it – zero premine set the standard that every project should follow
fair_launch_88 andre set the standard and then the entire industry ignored it. every launch since has had a team allocation, vc round, or hidden premine. YFI was genuinely one of a kind
YFI from 3 dollars to 40k in weeks. some of us farmed it and sold at 1k thinking we were geniuses lol
The gas fees during peak yield farming were brutal. Paying 50 bucks to move liquidity between pools
50 bucks to move liquidity between pools and people still did it because the yields were insane. gas was basically a tax on being early
yield_reaper_ selling YFI at 1k thinking genius move. we all did bro. we all did
50 gas fees for pool hops – that was peak DeFi insanity
zero premine but andre still got criticized for launching with no audit. dude literally gave away 100% of supply and people still found reasons to complain
pool_hopper_ the no audit thing was wild in hindsight. andre gave away 100% of supply and people still found reasons to complain. peak crypto entitlement
Lisa Chen 50 bucks to move liquidity and we still did it. the yields were so good the gas was just a tax on being early. peak degeneracy
gas_repentant_ 50 dollar gas to move liquidity was brutal but the yields were so good it didnt matter. until they werent and you were left holding farmed tokens worth nothing
i farmed YFI at 3 dollars, sold at 900 thinking i was a god, then watched it hit 40k a few weeks later. still havent recovered mentally
Anouk B. farmed at 3 sold at 900 and watched it hit 40K. thats the defining defi summer trauma. we all have our version of that trade
anouk same energy as selling eth at 14 dollars in 2017. the trauma is permanent lol
YFI going from 3 dollars to 40k in a few weeks broke everyones brain. nobody had seen a fair launch do that before and nobody has since
andre cronje set the standard with zero premine and then the entire industry spent 5 years ignoring it. every launch since has team allocation or VC rounds
YFI from 3 to 40k and back. the fair launch was real but the tokenomics were basically a velocity bomb. nobody held, everyone farmed and dumped
pool2_baggage_ YFI was a velocity bomb because there was no lockup no vesting no team allocation. pure market discovery with zero friction in either direction
