Yield farming in DeFi: What it is and how it works

Yield farming is a feature of decentralised finance (DeFi) platforms that enables users to participate in liquidity provision and earn protocol-based incentives. However, what is yield farming in DeFi, and how does it work? This guide breaks down the basics, how yields are generated, and what risks to be aware of.

Understanding yield farming

Yield farming is a method where users lock or stake their crypto assets in a DeFi protocol to potentially earn additional tokens or fees. These rewards are typically paid in the form of new tokens, trading fees, or interest, depending on the platform.

Unlike traditional finance, which often involves banks and intermediaries, DeFi operates on open, blockchain-based networks. These networks use smart contracts to allow lending, borrowing, and trading without a central authority. Yield farming supports this ecosystem by helping to provide liquidity, one of the core elements that keeps decentralised applications functioning smoothly.

Yield farmers usually interact with DeFi platforms like automated market makers (AMMs), lending protocols, or liquidity pools. By contributing their tokens, users help power these services and may be compensated for their participation.

How does yield farming work?

Yield farming generally involves contributing crypto to a liquidity pool—a smart contract that holds funds for decentralised trading, lending, or borrowing.

The process generally follows a few key steps:

Providing liquidity

To get started, many users deposit a pair of tokens (e.g. ETH and USDC) into a liquidity pool. Other users can trade between these tokens, with the protocol charging a small fee per transaction.

Earning fees or tokens

In return, users often receive a portion of those transaction fees. In many cases, protocols also issue liquidity provider (LP) tokens. These represent the user's share in the pool and may be eligible for further incentives.

Staking LP Tokens

In certain cases, LP tokens can also be staked in other smart contracts. This adds another opportunity to earn rewards, often in the form of governance tokens or additional tokens.

Managing returns

Yields in farming can vary significantly. The rate of return may depend on factors like total value locked (TVL) in the pool, trading volume, and the reward structure of the protocol. These can change quickly, especially in fast-moving markets.

Although the details can vary by platform, the underlying concept stays consistent: users provide capital and are rewarded for doing so.

Risks of yield farming

Alongside the potential for returns, yield farming comes with a number of risks. Understanding these is important before engaging in any yield farming strategies.

Impermanent loss

This occurs when the value of tokens in a liquidity pool changes compared to when they were deposited. If the price moves significantly, the value of a user’s share may be lower than if they had held the tokens outside the liquidity pool.

For example, if the price of one asset rises or falls significantly in the liquidity pool, the pool automatically rebalances by selling the asset that’s increasing in value and buying the asset that’s decreasing or staying stable. This keeps the pool balanced, but it may leave you with less of the more valuable asset and more of the less valuable one.

Smart contract risks

Smart contracts are automated and self-executing, but they’re still written by people. A coding error or vulnerability can be exploited by malicious actors, potentially leading to the loss of funds. Even well-audited contracts carry some level of risk.

Volatility

The value of digital assets can fluctuate rapidly due to market dynamics, global news, and trading volume. This is a known characteristic of the crypto market, which underscores the importance of understanding price movements before participating.

Project Risks

A few projects have limited testing or short-term goals, while others attract deposits without offering real utility. In some unfortunate cases, developers have abandoned or exploited their own projects—a situation sometimes referred to as a rug pull.

These risks highlight the importance of doing thorough research before engaging with any DeFi platform. We encourage all our customers to stay informed. Visit the BTC Markets Learn page for more articles like this one.
