DeFi Yield: What It Is and How to Earn Onchain

DeFi yield is one of the main reasons people use decentralized finance. Instead of only holding tokens in a wallet, users can deploy assets into onchain protocols and earn potential returns from trading fees, lending interest, staking rewards, liquidity incentives or other protocol-based revenue sources.

What Is DeFi Yield?

DeFi yield is the return generated when users deposit crypto assets into decentralized finance protocols. These returns can come from different activities, such as:

• Providing liquidity to decentralized exchanges
• Lending tokens to borrowers
• Staking assets to support blockchain networks or protocols
• Participating in farming or incentive programs
• Depositing into automated yield strategies
• Earning fees from onchain trading activity

Unlike traditional finance, DeFi yield is usually managed by smart contracts. Users connect a crypto wallet, deposit assets and interact directly with protocols without needing a bank account, broker or centralized intermediary.

Why DeFi Yield Matters

DeFi yield turns idle crypto assets into productive capital. For example, a user holding ETH, USDC or other tokens may choose to deposit them into a liquidity pool. That pool helps other users swap tokens. In return, liquidity providers may earn a share of trading fees or additional rewards. This creates a market where users can:

• Earn passive income onchain
• Access global financial opportunities
• Maintain more control over their assets
• Move capital between protocols and chains
• Compare yields transparently through public data

The key difference is that DeFi yield is open and programmable. Anyone with a wallet can participate, depending on the protocol, supported chain and asset availability.

Where Does DeFi Yield Come From?

DeFi yield is not magic. It comes from economic activity happening onchain.

1. Trading Fees From Liquidity Pools

Decentralized exchanges need liquidity so users can swap tokens. Liquidity providers deposit token pairs into pools, such as ETH and USDC. When traders use the pool, they pay swap fees. A portion of those fees may go to liquidity providers. This is one of the most common sources of DeFi yield.

2. Lending Interest

In lending protocols, users deposit assets that other users can borrow. Borrowers pay interest and depositors earn a portion of that interest. For example, someone may deposit USDC into a lending market. Borrowers who need USDC pay interest and the depositor earns yield.

3. Staking Rewards

Some networks and protocols reward users for staking tokens. Staking can help secure a blockchain, support governance or align users with a protocol's ecosystem. The reward structure depends on the network or protocol.

4. Liquidity Mining and Incentives

Protocols sometimes offer extra token rewards to attract liquidity. These incentives are often used to bootstrap new pools, chains or ecosystems. While incentive-driven APRs can look attractive, they may change quickly. Users should understand whether the yield comes from real usage, token emissions or both.

5. Automated Yield Strategies

Some platforms simplify yield by routing user deposits into selected strategies. These can include liquidity provision, auto-compounding, reward harvesting or multi-step DeFi actions. The goal is to make earning easier for users who do not want to manually manage every step.

Common Types of DeFi Yield Strategies

Different strategies come with different risk levels. Understanding the main categories helps users choose what fits their goals.

Liquidity Providing

Liquidity providing means depositing tokens into a pool used by a decentralized exchange.

Example: A user deposits ETH and USDC into an ETH-USDC pool. Traders swap between ETH and USDC using that pool. The liquidity provider earns a portion of swap fees.

Best for: Users who want to earn from trading activity.

Main risks: Impermanent loss, price volatility, smart contract risk and changing fee income.

Yield Farming

Yield farming usually refers to depositing assets into DeFi protocols to earn rewards. This may include LP fees, farming incentives or bonus tokens.

Best for: Users looking for higher reward opportunities.

Main risks: Reward volatility, token price drops, smart contract risk and unsustainable APRs.

Lending

Lending involves depositing assets into a lending protocol so borrowers can use them. Depositors earn interest.

Best for: Users who prefer simpler yield on assets like stablecoins.

Main risks: Borrower liquidation mechanics, protocol risk, liquidity risk and variable interest rates.

Staking

Staking involves locking or delegating tokens to help secure a network or participate in protocol-level systems.

Best for: Long-term holders of proof-of-stake assets or governance tokens.

Main risks: Lockup periods, validator risk, slashing risk and token price volatility.

Stablecoin Yield

Stablecoin yield focuses on assets like USDC, USDT or DAI. Since stablecoins are designed to track a fiat currency, this strategy can reduce price volatility compared with volatile token pairs.

Best for: Users who want lower market volatility.

Main risks: Stablecoin depeg risk, protocol risk, lower upside and changing APRs.

How APR and APY Work in DeFi

APR and APY are two common yield metrics.

APR, or annual percentage rate, shows the simple annualized return without compounding.

APY, or annual percentage yield, includes compounding. If rewards are reinvested regularly, APY can be higher than APR.

For example: If a pool shows 10% APR, that means the estimated annual return is 10% before compounding. If rewards are compounded frequently, the effective return may become higher.

However, DeFi APRs are not fixed. They can change based on:

• Trading volume
• Liquidity depth
• Token prices
• Reward emissions
• User participation
• Market volatility
• Protocol changes

A high APR today may be lower tomorrow.

What Is Impermanent Loss?

Impermanent loss is one of the most important risks in liquidity providing. It happens when the price ratio between tokens in a liquidity pool changes after a user deposits. If one token rises or falls significantly compared with the other, the value of the LP position may
