What is DeFi?
DeFi, or Decentralized Finance, is a blockchain-based financial ecosystem that allows peer-to-peer transactions without intermediaries. By 2026, DeFi continues to grow, offering investment and innovation opportunities, but also presents significant risks that users should understand.
Risks at DeFi in 2026
Recently, the DeFi market has seen remarkable cases of significant losses due to factors such as extreme slippage and maximum value extraction bots (MEV) attacks.
Extreme Slippage
A recent example is the case of a trader who lost $50 million on an Aave trade. The user ignored extreme slippage warnings and ended up receiving only 324 AAVE tokens. Aave offered a $600,000 refund in fees as compensation, but the incident highlights the importance of understanding the risks of slippage in large transactions.
Attack by MEV Bots
Another case involving Aave showed how MEV bots can profit from poorly executed transactions. A bot earned $10 million in a $50 million trade that went wrong. These bots exploit inefficiencies in the market and can cause significant losses for traders.
Regulation and Safety
By 2026, regulation of the US cryptocurrency market is becoming clearer, with the SEC and CFTC signing an agreement to harmonize supervision of cryptocurrencies, derivatives and hybrid products.
Impact on the Brazilian market
In Brazil, the regulation of the cryptocurrency market is evolving, with the Securities Commission (CVM) and the Central Bank of Brazil (BCB) working on clear guidelines.
How to Protect
To protect yourself in the DeFi market, it is essential to understand the risks and take preventive measures.

Before you execute large transactions, check the fees and slippage. Platforms like Aave offer extreme slippage warnings, and ignoring them can lead to significant losses.
Use of reliable platforms
