Year over year, the blockchain and decentralized finance (DeFi) market keeps recording tremendous growth which underlines its appeal. This growth comes with the introduction of innovations, investor-friendly regulations, institutional adoption, and many others.
To an extent, decentralized finance in recent times has caught the most attention in the blockchain space. This key market segment is one of the major factors that has propelled digital assets towards global adoption.
More so, the DeFi space is flourishing due to how it offers individuals and institutions an alternative to centralized finance. According to Nansen, as of 2023, decentralized finance has accumulated a massive $50 billion, with a projection to hit $231 billion by 2030.
Despite posting impressive figures lately, how hackers mostly target DeFi projects is a matter of serious concern among all market participants. At the moment, the DeFi space is enduring a testing period where cyberattacks and breaches are on the rise.
While the sector’s growth has convinced more investors to come aboard, it has also attracted the attention of hackers. This article aims to discuss the growth and downsides of the DeFi space and how it has become a weak link for hackers to move millions.
Growing DeFi attacks
Like most financial markets, the DeFi space is battling many threats that cut across regulation and security. These setbacks are posing serious dents in investors’ confidence in the blockchain and cryptocurrency market.
Further, it is evident that the decentralized finance industry remains one of the most vulnerable areas in the blockchain and crypto space. Similarly, hackers are on the rampage and continually exploiting DeFi’s open architecture and smart contracts.
Ranging from flash loan attacks to bridge exploits, bad actors are moving rapidly with the introduction of various mechanisms targeted at liquidity platforms. This series of eye-catching hacks highlights some shortcomings in smart contract design, private key management, and governance systems.
Furthermore, these issues if not properly addressed could deter the future of the sector. Meanwhile, one of the major reasons why DeFi hacks have been on the rise is the increasing inflow of funds to the sector.
According to DeFiLlama, the DeFi market currently holds $113 billion in Total Value Locked (TVL). Around September 2025, the market’s TVL skyrocketed to $170 billion but the recent price dip that rocked the crypto market forced a price correction.
Despite that, the figure points to the growth of the decentralized finance market which only held $616 million TVL as of January 2020. While the advancement of the sector is evident and it has not only caught the attention of investors but also attracted bad actors.
Hacken in a report revealed that decentralized finance protocols lost more than $3.1 billion to cyberattacks in the first half of 2025. This figure significantly surpasses the $2.8 billion the crypto space lost to bad actors in the previous year.
Parting Words
However, despite the incessant attacks, one fact remains the same that the core blockchain technology is impenetrable. Thanks to its cryptographic setup, blockchain technology is immutable and designed to run around the clock without suffering a shutdown.
Therefore, the increasing loot of DeFi treasuries by hackers points to how the market sector is fast becoming a soft target. This menace is largely due to how most decentralized finance platforms fail to carry out regular smart contract audits.
Aside from mentioning protocols with poorly written code, most project teams only carry out checks on their protocol for marketing purposes. Also, internal audits and automated tools cannot pick out some loopholes, giving hackers the opportunity to attack.
Additionally, most DeFi users barely understand how the tools work leaving them vulnerable to lurking predators. Proper education will provide users and investors alike with the needed knowledge to safeguard their assets.
Don’t forget that decentralized finance stands out with its full-custody system that allows users to remain in control of their cryptocurrencies. Capitalizing on that, hackers often lure inexperienced users to give up their assets through phishing links.
So, it is imperative for all market participants to join forces and find a solution to these issues. Failure to bring the peril under control, the DeFi sector will continue to remain a weak link for hackers.
