Decentralized Finance (DeFi) is a system that delivers financial services via smart contracts on blockchains without relying on central intermediaries. As of 2026, DeFi has evolved from a speculative topic into core infrastructure for business design, with institutional investors driving the tokenization of Real-World Assets (RWA) and regulatory frameworks for stablecoins advancing under revised Payment Services Act legislation. This article explains the fundamentals of DEXs, lending, and liquidity provision, along with the essential risks you must understand.
How DEXs (Decentralized Exchanges) Work
A DEX is an exchange where users can directly swap cryptocurrencies with one another. Unlike Centralized Exchanges (CEXs), where a company manages assets, DEXs utilize smart contracts to automatically execute trades. A representative model is the AMM (Automated Market Maker), which employs liquidity pools. Users deposit two types of tokens into these pools, and prices are determined based on their ratio. Since all transactions are recorded on-chain, transparency is high; however, trading fees and slippage (price deviation) do occur. Fee rates vary by protocol and pool, so be sure to verify the latest rates via official sources before use.
How Lending Works
Lending is a service where you earn interest by lending out crypto assets, or borrow assets by depositing collateral. Smart contracts automatically match lenders and borrowers, with interest rates fluctuating based on supply and demand. Borrowers are generally required to provide over-collateralization; if the collateral value falls below a certain threshold, forced liquidation occurs. In 2026, lending backed by Real World Assets (RWA) has also emerged, enabling borrowing secured by physical assets. However, since interest rates and liquidation conditions vary by protocol, it is crucial to understand the specific terms beforehand.
How Liquidity Provision Works and Revenue Generation
Liquidity provision involves depositing tokens into a DEX liquidity pool to earn a share of trading fees. However, if the ratio of deposited tokens fluctuates, there is a risk of "impermanent loss," where assets withdrawn may be worth less than the initial principal. This risk is particularly pronounced in pairs with high price volatility, meaning liquidity provision does not guarantee stable returns. Additionally, there is no denying the possibility of losing deposited assets due to smart contract bugs or hacking incidents. When considering liquidity provision, please review the protocol's audit status and history of past incidents, and make decisions at your own responsibility.
Inherent Risks of DeFi
DeFi involves the following risks:
- Smart Contract Risk: Vulnerabilities in the code may result in assets being stolen or locked.
- Price Volatility Risk: Cryptocurrency prices can fluctuate significantly over short periods, potentially triggering forced liquidations due to a sharp decline in collateral value.
- Liquidity Risk: Low pool liquidity may prevent you from executing trades at your desired price.
- Regulatory Risk: Changes in regulations across different countries may render specific DeFi services unavailable.
- Principal Loss Risk: When engaging in lending or providing liquidity, there is a possibility that your principal amount may decrease.
Understanding these risks, ensure you invest only within the limits of your disposable funds and maintain a diversified portfolio.
Summary
DeFi is an innovative financial system that operates without a central administrator, but it also carries unique risks not found in traditional finance. As of 2026, with increasing institutional participation and advancing legal frameworks, DeFi is becoming more integrated with the real economy. However, risks such as price volatility, smart contract vulnerabilities, and regulatory changes still persist. When using DeFi, ensure you fully understand its mechanisms, verify the latest fees and terms via official sources, and act at your own responsibility.

Frequently Asked Questions
What is the difference between DeFi and a centralized exchange (CEX)?
DeFi operates without a central authority, using smart contracts for automated management, whereas a CEX is run by a company that manages user assets and facilitates trades. DeFi offers greater transparency but requires users to manage their own assets and assume full responsibility.
Is liquidity provision always profitable?
No. While liquidity providers earn trading fees, they also face risks such as impermanent loss and price fluctuations that can reduce their principal. Profits are not guaranteed, and losses are possible.
What do I need to start using DeFi?
You need a wallet that can store crypto assets (e.g., MetaMask) and some crypto to transact with (e.g., ETH). You will also need to pay network fees, known as gas fees, which vary. Always check the latest fee information on official sites.
What triggers a forced liquidation in DeFi lending?
If the value of the collateral you deposited falls below a certain ratio relative to your borrowed amount (e.g., 150%), a forced liquidation occurs. Assets with higher price volatility carry greater liquidation risk.
What are the key DeFi trends to watch in 2026?
Institutional adoption of real-world asset (RWA) tokenization and regulatory developments for stablecoins under revised payment laws are advancing. These trends are shifting DeFi from speculation toward a business infrastructure role.
