“DeFi Summer” was an event that has its place etched in crypto history books. It’s one of the catalyst events that led to bullish developments within DeFi(Decentralized Finance) and huge expansions in terms of technological infrastructure.
Occurring in the same year as the COVID-19 global pandemic, it propelled DeFi’s TVL(Total Value Locked) from millions to billions. Shocking investors who witnessed the massive growth amassed by an entire industry in just a few months.
The DeFi industry was by no means a newly built industry in 2020. However, it was the season that the industry reached new heights. Let’s take a dive into what exactly is the DeFi summer and the challenges it has faced in the crypto space.
What is DeFi Summer
DeFi Summer refers to the season of summer 2020. This period resulted in the emergence of viable alternatives to traditional centralized finance called decentralized apps that offered an array of inclusive financial services such as yield farming, lending and borrowing, and insurance.
DeFi Summer primarily stars “DeFi”, a type of financial service that uses blockchain technology, smart contracts, and Decentralized apps to offer financial services without relying on middlemen such as banks or governments. DeFi platforms such as Compound, Aave and Curve introduced its governance token that enabled users to earn rewards called “liquidity mining”.
Liquidity Mining allowed users to earn yields, participate in governance, and exchange it for fiat on Decentralized exchanges. Certain investors would even develop DeFi farming strategies by hopping between exchanges in hopes of getting the best APY.

The attractive prospect of earning passive income led to massive amounts of money flowing into the DeFi space. Early on, DeFi encountered a “chicken or egg” problem that was soon solved during the influx of capital and users in DeFi summer. The problem of liquidity was finally solved and it felt like it was going to be smooth sailing from now on.
Challenges
The DeFi industry had to face many challenges as the months went on. The space experienced numerous protocol hacks and a plethora of lazy copy-paste projects that sought to emulate the success of its predecessors. Harvest Finance, was hacked for $24 million while $7 million was stolen from Origin protocol within the same year.
In a decentralized space such as crypto, a lack of governing authority to verify legitimate from non-legitimate resulted in many of these challenges. The generation of many copy-paste DeFi farms also resulted in many naive DeFi investors who were looking for the next big protocol. An attitude of DYOR(Do Your Own Research) echoed throughout various social media spaces, suggesting to newer investors in crypto to watch out before pouring money into random protocols.
Final Thoughts
A fact that stands throughout the test of time are that markets are cyclical. The hype generated during the summer definitely wouldn’t last long and would soon deflate as time went on. Certainly, DeFi summer was a definite jaw-dropping experience that led to thousands of users gaining abrupt generational wealth. The success of DeFi in 2020 challenged everyone’s preconceptions about finance and may as well have laid both the psychological and technical foundations for better and more inclusive finance for all.
