What is DeFi and how to invest in 2026

DeFi (Decentralized Finance) is a financial system that operates without banks or intermediaries, using blockchain and smart contracts to automate operations such as lending, investing, and cryptocurrency trading. Anyone with internet access and a digital wallet can access these financial services in a global and transparent manner.

The blockchain technology functions as a public and immutable ledger where smart contracts eliminate traditional bureaucracy. There is no credit analysis, institutional approval, or abusive fees. In 2025, the total value locked (TVL) in DeFi protocols exceeded US$ 300 billion, consolidating the sector as a real alternative to the traditional financial system.

Main DeFi protocols to invest in

Get to know the best DeFi protocols to start investing:

Uniswap: The largest decentralized exchange (DEX) on the market. It operates with liquidity pools where users deposit token pairs and earn a portion of transaction fees. Uniswap v3 allows for concentrated liquidity, maximizing returns.

Aave: Leader in DeFi lending. It allows users to lend and borrow crypto assets with competitive rates. Aave V3 introduced interoperability between blockchains and uses artificial intelligence for risk analysis.

Lido: A benchmark in liquid staking for Ethereum. You stake ETH and receive stETH in return, which can be used in other DeFi applications while generating rewards.

Compound: A pioneering platform for automated lending. Lend assets and receive interest or take out loans using crypto as collateral. Rates adjust automatically based on supply and demand.

Curve: Specialized in stablecoin swaps with very low fees and minimal slippage. Ideal for those seeking stability and consistent yield.

MakerDAO: Creator of the decentralized stablecoin DAI, backed by crypto assets. You lock ETH or other tokens to generate DAI, maintaining parity with the dollar.

4 Ways to earn passive income with DeFi

Investing in DeFi offers several return strategies:

1. DeFi Staking

You "lock" your crypto assets in a protocol to help secure the network and receive periodic rewards. In liquid staking (such as on Lido), you receive a derivative token that you can use in other applications while continuing to earn rewards.

2. Yield Farming

Provide liquidity to pools on decentralized exchanges like Uniswap and Curve. You deposit token pairs (e.g., USDC and DAI) and receive LP (Liquidity Provider) tokens that represent your share. In return, you earn a portion of transaction fees and additional rewards. Attention: there is a risk of impermanent loss when token prices fluctuate.

3. Lending

Lend your assets on protocols like Aave and Compound. Funds go into pools controlled by smart contracts that automate interest and payments. Rates vary according to supply and demand. Borrowers must provide collateral, reducing default risk.

4. Airdrops

Free distributions of tokens by new projects. Some are automatic for those holding certain assets; others require tasks such as trading on DEXs or participating in governance. Always verify if the airdrop is official; never share your private keys.

Important: Diversify your investments, research the protocols, and use only audited platforms. Returns can be attractive, but risks include volatility, bugs in smart contracts, and potential scams.
