Liquidity mining has become one of the most powerful engines of growth in decentralized finance (DeFi). Since 2020, DeFi protocols have distributed more than $7 to $8 billion in fees directly to liquidity providers, alongside billions more in governance tokens such as UNI, CAKE, COMP, and AAVE. This makes liquidity mining one of the largest wealth-sharing mechanisms in crypto, rewarding participants with both income and governance rights.

The scale today is remarkable. Since 2018, Uniswap has generated nearly $4.9 billion in user fees, with more than $4.8 billion already paid out to liquidity providers (LPs). At current volumes of over $4.5 billion traded each day, that amounts to about $2.5 to $3.5 million in daily rewards shared among LPs. Other platforms tell a similar story. PancakeSwap has distributed nearly $3.3 billion to its liquidity providers since 2020, while Aave depositors have earned around $1.45 billion through lending interest and fee income.
From its experimental beginnings, liquidity mining has matured into a cornerstone of DeFi, delivering passive income opportunities for individuals while providing the deep liquidity needed to keep decentralized markets running smoothly.
What Is Liquidity Mining and How Does it Work?

Liquidity mining is the process of depositing crypto assets into decentralized finance (DeFi) protocols, most often decentralized exchanges (DEXs) or lending platforms, to provide liquidity. In return, participants earn rewards in several forms:
• Trading fees: A share of the fees generated whenever users swap tokens in the pool.
• Interest payments: Earnings from borrowers when liquidity is supplied to lending platforms.
• Governance tokens: Extra rewards such as UNI, CAKE, or COMP that give holders voting rights in protocol decisions.
At its core, liquidity mining ensures markets have enough liquidity for users to trade or borrow assets efficiently without excessive slippage.
The system works through liquidity pools, which are smart contracts that hold pairs of tokens. Automated market makers (AMMs) keep these pools balanced and set prices. When traders swap tokens, they pay a fee that is distributed to liquidity providers (LPs). Many protocols also add governance tokens to boost rewards.
By contributing tokens, users receive LP tokens representing their share of the pool, which can be redeemed for their assets plus rewards. For example, depositing ETH and USDC into a pool lets an LP earn a share of trading fees and incentives.
This model first gained traction with Compound’s COMP launch in DeFi Summer 2020. Since then, it has spread across major networks like Ethereum, Solana, BNB Chain, Base, and Arbitrum. Since 2020, DeFi protocols have distributed over $7–8 billion in fees to liquidity providers, making liquidity mining one of the largest wealth-sharing mechanisms in crypto and a cornerstone of DeFi.
History of Liquidity Mining: DeFi Summer 2020
Liquidity mining first gained widespread attention during the period known as DeFi Summer 2020. Before then, decentralized exchanges like Uniswap had introduced the concept of liquidity pools, but incentives were largely limited to trading fees. Everything changed in June 2020 when Compound Finance launched the COMP governance token.
Compound (COMP) not only rewarded users with interest for supplying or borrowing assets, but also distributed COMP tokens to those who participated. This new layer of rewards transformed providing liquidity into a yield-generating strategy and triggered a rush of capital into DeFi. Within weeks, Compound’s total value locked (TVL) surged from under $100 million to more than $600 million, and the wider DeFi market followed suit. According ot DefiLlama, by the end of 2020, DeFi TVL had skyrocketed from less than $1 billion at the start of the year to over $15 billion.

Other platforms quickly joined in. SushiSwap famously launched by “vampire attacking” Uniswap’s liquidity and distributing SUSHI tokens, while Curve and Balancer offered similar token incentives to bootstrap their ecosystems. This period established liquidity mining as more than a short-lived experiment. It demonstrated that incentivizing liquidity with both fees and governance tokens could bootstrap entire markets and accelerate DeFi adoption at a scale never seen before.
How to Become a Liquidity Provider on DeFi Protocols
Becoming a liquidity provider is one of the simplest ways to participate in decentralized finance. While the specific steps vary across platforms, the process generally follows a similar pattern:
Step 1: Set up a crypto wallet
Install a DeFi-compatible wallet such as MetaMask or Trust Wallet. Fund it with the tokens you plan to provide as liquidity.
Step 2: Choose a DeFi protocol
Decide where you want to provide liquidity:
• Decentralized Exchanges (DEXs): Deposit equal values of two tokens (e.g., ETH/USDC) into a liquidity pool. You’ll earn trading fees whenever users swap between those tokens, and often receive governance tokens like UNI or SUSHI.
• Lending Protocols: Supply a single token (e.g., ETH, USDT, or DAI) to platforms such as Aave or Compound. You’ll earn interest from borrowers plus potential protocol token rewards.
• Stablecoin Pools and Yield Aggregators: Contribute to specialized pools like Curve’s 3pool for steady stablecoin demand, or use yield aggregators such as Yearn Finance (YFI) or Beefy Finance (BIFI) that automatically optimize your liquidity across protocols.
Step 3: Deposit your assets
Connect your wallet to the chosen protocol and deposit the required tokens. In return, the protocol issues you LP tokens (or deposit receipts) that represent your share of the pool or lending market.
Step 4: Earn rewards
Rewards are generated over time in the form of trading fees, interest, or governance tokens. Many protocols allow you to claim rewards periodically or reinvest them for compounding growth.
Step 5: Withdraw when needed
At any time, you can redeem your LP tokens to withdraw your original assets along with the rewards you’ve earned.
Tip for beginners: Start with smaller amounts on well-established, audited platforms to learn how liquidity mining works before committing larger sums or experimenting with advanced strategies.
Providing liquidity allows you to put idle assets to work while supporting the wider DeFi ecosystem. Whether through DEXs, lending markets, or stablecoin pools, the basic structure remains the same: deposit assets, receive proof of contribution, and earn a share of the economic activity that flows through the protocol.
Liquidity Mining vs. Yield Farming: What Are the Key Differences
Yield farming is the broad strategy of moving assets across different DeFi protocols to maximize returns. It can involve lending, staking, borrowing, and reinvesting rewards in new pools to compound yields. Within this umbrella, liquidity mining is one of the most common approaches. It focuses specifically on supplying tokens to liquidity pools on decentralized exchanges or lending platforms, where providers earn a share of fees and often governance tokens as extra incentives.
In other words, liquidity mining is a subset of yield farming. The distinction matters because liquidity mining is usually simpler and more accessible for beginners, while yield farming as a whole tends to be more complex, requiring active management and a higher tolerance for risk.
Liquidity Mining vs. Liquid Staking: Which One Should You Choose
Liquidity mining and liquid staking are two of the most popular ways for crypto holders to earn passive income, but they work very differently.
Liquidity mining: Involves depositing assets into decentralized exchanges or lending pools to facilitate trading or borrowing. Rewards typically come from trading fees and governance tokens. Liquidity providers take on risks such as impermanent loss and token volatility but can benefit from higher potential yields.
Liquid staking: Allows users to stake tokens, such as ETH, on proof-of-stake networks while receiving a liquid derivative token (for example, stETH from Lido). This derivative can be used in DeFi while the original tokens continue earning staking rewards. Risks are lower compared to liquidity mining, but yields are usually more modest.
How to decide:
• Liquidity mining suits users who want exposure to active DeFi trading and can tolerate higher risks.
• Liquid staking is better for those who prefer a simpler, long-term strategy with more predictable returns.
Some investors combine both by using staked assets as collateral in liquidity pools, effectively stacking yields for higher overall returns.
Advantages of Liquidity Mining
Liquidity mining has become one of the most popular entry points into DeFi because it offers benefits that go beyond individual profit. It creates opportunities for passive income while also strengthening the foundations of decentralized markets. Key advantages include:
1. Passive income opportunities: By providing liquidity, users earn a share of transaction fees or interest, creating a steady income stream without the need for active trading. Additional governance tokens distributed by protocols can further boost returns.
2. Democratized market-making: In traditional finance, liquidity provision is dominated by institutions. DeFi opens this role to anyone with tokens, allowing retail investors to participate and benefit from rewards.
3. Portfolio diversification: Liquidity mining can give exposure to multiple assets within a pool. Stablecoin pools offer lower-risk options, while volatile token pairs allow users to capture upside potential.
4. Governance participation: Many protocols distribute governance tokens to liquidity providers, enabling them to vote on proposals and influence the direction of the platform.
5. Strengthening the ecosystem: Liquidity mining improves the efficiency of decentralized exchanges and lending platforms by reducing slippage, deepening liquidity, and attracting more users, which benefits the entire DeFi space.
Risks and Considerations Before Starting Liquidity Mining
While liquidity mining offers attractive opportunities for passive income, it also comes with risks that every participant should understand. Evaluating these factors before committing funds can help minimize losses and set realistic expectations.
1. Impermanent loss: When token prices in a pool move apart, providers may end up with fewer assets in dollar terms compared to simply holding them.
2. Smart contract vulnerabilities: Bugs, exploits, or flash loan attacks can compromise DeFi protocols and lead to the loss of deposited funds.
3. Token reward volatility: Incentive tokens earned through liquidity mining can fluctuate sharply in value, reducing actual returns.
4. Market risks: Trading volume and price trends directly affect fee generation. In bearish markets, yields for liquidity providers often decline.
5. Regulatory uncertainty: DeFi operates in a largely unregulated environment, and future regulations may affect participation or profitability.
Conclusion
Liquidity mining has matured from its early days in DeFi Summer 2020 into a fundamental part of decentralized finance. By supplying assets to exchanges and lending protocols, liquidity providers earn a share of transaction fees and governance tokens, all while ensuring that markets remain liquid and efficient. This democratized model has opened the door for anyone with crypto to participate in activities once reserved for institutions, turning passive assets into income-generating tools.
At the same time, liquidity mining is not without risks. Impermanent loss, token price volatility, smart contract exploits, and shifting market conditions can all affect returns. For newcomers, starting with smaller amounts on established platforms is a sensible way to gain experience before exploring more advanced strategies like yield farming or combining liquidity mining with liquid staking. As DeFi adoption grows and billions in daily trading volume flow through decentralized protocols, liquidity mining is likely to remain both a key income stream and a cornerstone of the broader crypto economy.
