It is important to be aware of the risks when providing liquidity. One of the most well-known risks is impermanent loss, but others include market volatility, out-of-range positions, smart contract vulnerabilities, and untrusted or unverified token teams. All of these can impact a user's liquidity and potentially cause a loss of funds.
Impermanent Loss (IL): This occurs when the price of tokens in a liquidity pool diverges significantly from the price of those tokens on other protocols or exchanges. Over time, the IL can become significant, and may not become permanent. It's important for liquidity providers to consider this when supplying liquidity with large price variations externally.

Market Volatility: Changes in the prices of tokens in a liquidity pool can impact the value of the liquidity provider's position.
Out-of-range: When a position is out of range, it will not earn liquidity provider fees. LPs must manage the position range, keeping in mind the network costs of managing the position range.
Smart Contract Vulnerabilities: Liquidity pools operate on smart contracts, which can be susceptible to bugs or exploits, potentially causing funds to be lost.
Locked Liquidity and Rug Pulls: The Uniswap protocol is a permissionless, decentralized protocol. No central authority can restrict who can or cannot use it. Anyone can swap, provide liquidity, or create new markets at will. Given this, it's extremely important to do as much research as possible on the token and its creators (the “token team”). As an example, if the token team is the primary liquidity provider, users should check for locked liquidity. If the team's liquidity isn't locked, this means the token team can remove liquidity whenever they choose.
Other Risks: Liquidity risk can also arise from poor LP management, network costs, or lack of funding, just to name a few. This is why it's important to set up your LP based on your level of risk versus reward, keeping in mind the network costs of adding, managing, and removing liquidity.
