If you've ever tried to buy or sell a cryptocurrency only to realize you couldn't easily exit the trade, you've experienced the pain of low liquidity. Liquidity is one of the most important concepts in crypto markets, but is also one of the most misunderstood.
In this guide, we'll cover everything you need to know about liquidity in crypto — from what it means, how liquidity pools work, what locked liquidity is, and even how to check and calculate liquidity yourself.
At its core, liquidity measures how easily you can buy or sell an asset without drastically changing its price.
Liquidity is crucial because it determines:
A liquidity pool is a collection of tokens (commonly two tokens) locked in a smart contract that powers decentralized exchanges like Uniswap or Raydium.
Instead of traditional buyers and sellers placing orders in an orderbook, users trade directly against these pools. These liquidity pools ensure that there is always passive liquidity to trade against, provided by liquidity providers. This is compared to traditional order books made up of active liquidity, requiring liquidity providers (for order books, known as market makers) to actively provide liquidity and remove it as prices and market conditions change.
Liquidity pools are what make decentralized trading possible without centralized order books, such as those seen in stock exchanges like NASDAQ or the New York Stock Exchange.
Liquidity pools rely on Automated Market Makers (AMMs). The most common formula the Automated Market Maker uses to provide liquidity is: x * y = k.
The constant product k is determined when liquidity providers deposit into the pool. As people trade, the ratio of tokens shifts, changing the price. This automatically creates a market for the tokens in the liquidity pool.
Using the above formula, let's consider a liquidity pool comprised of ETH and USDC:
x = 10 (ETH)
y = 50,000 (USDC)
k = 500,000
If a user wants to swap 1 ETH for USDC, the pool will receive 1 ETH so x increases from 10 to 11. Given that k has to remain constant, the Automated Market Maker calculates that the new y will be 500,000 / 11 = 45,455. This means that the liquidity pool should have 45,455 USDC left after the swap. Thus, the user receives 50,000 (y before the swap) - 45,455 (y after the swap) = 4,545 USDC in return for his 1 ETH.
LPs benefit by earning a portion of trading fees. However, they face impermanent loss if token prices move unfavorably compared to simply holding the tokens independently outside the liquidity pool.
Locked liquidity refers to funds in a liquidity pool that are time-locked in a smart contract. Developers or liquidity providers cannot remove them until the lock expires. Another form of locked liquidity is when liquidity is burned, where the ownership of the deposited liquidity is forfeited, thus the liquidity is locked forever.
Why it matters:
Example: A new token might launch on pumpfun and lock its token/SOL pool liquidity by burning it.
"Exit liquidity" is a term for when new buyers are effectively the liquidity that allows early investors or insiders to sell their tokens at higher prices.
Understanding liquidity can help you avoid these scenarios by checking the amount in liquidity pools and what % of the token the top holders hold before entering a position. These are easily viewable in fomo by tapping on the "About" section of a token and viewing the liquidity and holder details.
Putting it all together:
Liquidity directly impacts:
Here are practical ways to evaluate liquidity:
Liquidity is often approximated by looking at pool reserves.
Example:
A Uniswap pool has 500 ETH and 1,000,000 USDC.
Liquidity (in USD terms) ≈ value of the reserves.
Note: Liquidity is not the same as market cap. A token can have a high market cap but low liquidity, making it hard to trade. This is an important factor as the token could theoretically be worth a lot, but as soon as holders start selling into low liquidity, the token price could rapidly drop.
Liquidity is the lifeblood of crypto markets.
If you're new to trading, make liquidity checks part of your due diligence. Use the fomo app to instantly check the liquidity of any token.
Liquidity measures how easily you can buy or sell a crypto asset without moving the price.
It means tokens in a pool are locked in a smart contract and can't be withdrawn for a set time or permanently, building trust.
A smart contract holding token pairs that traders can swap against on DEXs.
They use AMM formulas like x*y=k to determine prices automatically.
When late buyers are the ones insiders sell to — leaving them holding depreciating assets.
By using an app like fomo or checking order book depth on exchanges.
By summing the value of reserves in a liquidity pool, typically in USD terms.
