Basics

Making a crypto swap on a [decentralized exchange](https://blog.uniswap.org/what-is-a-decentralized-exchange) only takes a few clicks. The convenience and reliability of these onchain swaps is made possible, in part, by “liquidity providers” who supply tokens to liquidity pools, which are a cornerstone of [decentralized finance](https://blog.uniswap.org/what-is-defi). These pools enable trading, help balance prices, and can reward providers in return.

Discover how liquidity provisioning (or “LPing”) on [automated market makers](https://blog.uniswap.org/what-is-an-automated-market-maker) works and how to weigh the potential rewards against the risks and responsibilities of managing a liquidity position.
# What is liquidity provisioning?
Liquidity provisioning (or LPing) involves depositing a pair of tokens into a liquidity pool on a decentralized exchange like the Uniswap Protocol. These pools use smart contracts to enable permissionless, onchain trading.

By supplying liquidity, liquidity provisioners (or LPs) help ensure that traders can swap tokens efficiently, with minimal slippage when pool depth is high. In return, LPs earn a share of the trading fees — and in some cases, additional rewards.

Not all onchain activity involves LPs, but without them, the open markets that define DeFi wouldn’t exist.
# How do I become a liquidity provider on Uniswap?
Anyone can LP on Uniswap. There’s no minimum deposit required, and it’s easy to get started with just a pair of tokens. Some users add a little liquidity to learn, while others build more active strategies.

Becoming a liquidity provider starts with choosing a pool and depositing two tokens — like USDC and ETH. The amounts you deposit will be equal in market value. To LP on the Uniswap Protocol, this can be done directly through the [Uniswap Web App](https://app.uniswap.org/positions/?utm_medium=blog&utm_source=blog&utm_campaign=lp-blog&utm_content=uniswap-positions).

Once deposited, the tokens sit in a smart contract and provide liquidity for other users’ swaps. Every time someone trades against the pool, each LP that has contributed to the pool earns a portion of the trading fees, proportional to their share of the total liquidity.

LPs can add, remove, or adjust their position at any time — and they can collect their earned fees whenever they choose.

# Evaluating LP rewards and mitigating risks

Providing liquidity comes with tradeoffs, and understanding them can help you make smarter decisions if you choose to LP.

**1. Impermanent loss.** When the price of one token in your pair changes relative to the other, your position may be worth less than if you had simply held both tokens. Fees can help offset this, but not always. This loss, however, only becomes permanent if you withdraw your liquidity while prices are still out of balance.

**2. Market volatility.** Sharp price swings can increase the likelihood and impact of impermanent loss — which can be more common in volatile or uncorrelated pairs. 

**3. Fee variability.** LPs earn a portion of trading fees, but earnings depend on how much trading occurs — and whether your position is active within the pool’s price range.

**4. Price range exposure.** On Uniswap v3 and v4, you only earn LP rewards when the market price stays within your selected range. If the price moves out of range, your position may stop earning fees until you adjust it. In an earlier version of the Uniswap Protocol, v2, liquidity is always active across all price levels, and custom ranges are not available.
# More considerations for participation in onchain markets

With the right approach, LPing becomes a strategic way to participate in onchain markets. A few more considerations:

- **Choose token pairs you understand.** Get familiar with each token’s market dynamics — like what drives its price, how volatile it tends to be, and how it's used onchain.
- **Look for pools with steady trading and tokens that tend to move together in price.** These pairs — for example, many stable-stable pairs — often earn more consistent fees and are less likely to experience large impermanent losses.
- **Use platforms that offer control, transparency, and secure pools.** The [Uniswap Web App](https://app.uniswap.org/positions/?utm_medium=blog&utm_source=blog&utm_campaign=lp-blog&utm_content=uniswap-positions) lets you track performance, adjust your range, collect fees, and exit your position at any time.
- **Adjust your position based on how you think the market will move.** Tighter ranges concentrate your capital and can earn more fees — but they stop earning if the price moves out of range. [Learn how concentrated liquidity works →](https://docs.uniswap.org/concepts/protocol/concentrated-liquidity)

With a thoughtful setup and a bit of maintenance, LPing can be a practical way to participate in DeFi markets — and earn along the way. As with trading or any other DeFi activity, take time to understand what you’re participating in and do your own research.

Liquidity pools are the backbone of DeFi. Here’s what to know before you provide liquidity (LP) onchain.

Understanding Liquidity Provision in DeFi

Today we’re excited to announce Continuous Clearing Auctions (CCA), a permissionless protocol that helps teams bootstrap liquidity on Uniswap v4 and find the market price for new and low-liquidity tokens.

This is the first of several tools we’re building to help projects launch and deepen liquidity on the Uniswap protocol.

Built in collaboration with Aztec, the first project to launch with CCA, the protocol also includes an optional ZK Passport module that enables private, verifiable participation.

## What CCA solves

Liquidity formation often happens behind closed doors. That creates information gaps, privileges a few players, and can leave markets thin and unstable. We think there is a better way. CCA was designed around three core principles:

* **Onchain-native market creation.** The entire auction runs onchain, with pricing, bidding, and settlement happening transparently. No gatekeepers or offchain deals. 
* **Fair, gradual price discovery.** Supply is distributed over time through a continuous clearing process. This incentivizes bidding early, reduces sniping, limits volatility, and helps the market converge toward a fair value. 
* **Automatic liquidity seeding on Uniswap v4.** When the auction ends, proceeds automatically create a Uniswap v4 pool at the discovered price, deepening liquidity.

## How it works
<Video source="//videos.ctfassets.net/oc3ca6rftwdu/6pC1HQfR9sqCc1dJ2NOKdz/3cb11729cb594f8c697317bbdf8efb54/CCA-optimized-for-web.mp4" description="DESCRIPTION" />

**Setting up the auction**

Projects start off by defining how many tokens to sell, a starting price, and how long the auction will run. They can also customize with options like running in tranches, adding verification tools such as ZK Passport, or building entirely new modules on top of the platform.

**Placing bids**

Users then submit bids, specifying a maximum price and a total spend. Bids are non-withdrawable while in range (can be withdrawn if they’re out of range) but users can place as many as they like while the auction is live. Each bid is automatically spread across the remaining blocks of the auction, using the same max price for every split. A bid only fills if the block’s clearing price is at or below the bidder’s limit.

**Finding a price**

At the end of each block, the protocol sets a single market-clearing price – the highest price where all tokens for that block can be sold. Higher bids fill first, then bids at the clearing price, pro rata if needed. Everyone who fills in that block pays the same price.

As more bids come in and supply per block stays pre-set, clearing prices stay the same or trend upward. Early bidders tend to get a better average price since a larger portion of their bid can fill in earlier, cheaper blocks.

## What’s next

The Continuous Clearing Auction contract is live, and available for anyone who wants to use it. In the coming months, we’ll release additional modules to improve the experience for projects and communities launching with CCA.

Continuous Clearing Auctions: Bootstrapping Liquidity on Uniswap v4

If you’ve recently begun to explore and use DeFi apps, you may be surprised to see a “gas fee” added to the cost of your onchain transactions. Don’t worry, these fees are normal. 

Gas fees are set and collected by the blockchains that decentralized exchanges, NFT marketplaces, and other apps rely on to run properly — kind of like how payment networks collect fees on credit card transactions. And while they’re collected automatically when your transaction is submitted, there are a few helpful things to know about gas fees to avoid surprises or confusion. 

# Why are gas fees collected on every Ethereum transaction?
The gas fees you pay on your transactions help keep decentralized blockchains like Ethereum secure and working properly. 

Blockchains with high usage require a lot of computing power, plus the hardware used to run the network, and both of these come at a cost. Ethereum processes more than [one million daily transactions](https://etherscan.io/chart/tx) — so you can imagine the total costs required to keep things running smoothly. 

By charging a gas fee on every transaction, Ethereum can cover all of the expenses that come along with processing these transactions. 

## Who receives Ethereum gas fees?
The Ethereum blockchain is able to be decentralized thanks to a network of computers run by “validators” that work in harmony to submit blocks of transactions with no interruptions. 

Ethereum distributes gas fees as an incentive to validators, which motivates them to continue operating the network and keep it secure. 

__Reminder__: Gas fees are not collected by the app or wallet you’re using for your transaction — this is done by the blockchain that your app is deployed on.

# How are gas fees calculated?
Ethereum calculates gas fees using a [specific formula](https://ethereum.org/en/developers/docs/gas/). The formula ensures that fees are dynamic, meaning that they’re calculated fairly based on three factors: 

- The complexity of your intended transaction 
- The current demand on the blockchain network
- The speed that you want your transaction executed 

In other words, if your transaction is complex, submitted when network usage is high, and/or you want a network validator to prioritize it, you may need to pay a higher gas fee. As a result, your gas fees will differ from transaction to transaction. 

By default, your wallet uses this formula to run the numbers for you and provide an estimated gas fee for your transaction.
![Gas Fee on Uniswap Web App](//images.ctfassets.net/oc3ca6rftwdu/1f9Txb1o0R2pruLb5nizCr/b3d10c9807aec8e2d9e39d4fd7086f24/Gas_Fee_on_Uniswap_Web_App.gif)
*This demo shows how gas fees are displayed in the Uniswap web app.*
# How are gas fees paid?
Gas fees are paid in the form of a blockchain’s native token, and in Ethereum’s case that token is ETH.

Your gas fee won’t be paid unless you confirm your transaction. After confirming, the amount of ETH required to cover your gas fee will be automatically deducted from your ETH balance. 

If you don’t have enough ETH to pay the gas fee, the transaction won’t go through. If that happens, you can transfer funds from another wallet. 

Some crypto wallets, like [Uniswap wallet](https://wallet.uniswap.org/?utm_medium=blog&utm_source=blog&utm_campaign=eth-gas-fees&utm_content=uniswap-wallet), also offer fiat-to-crypto onramps so you can easily purchase the network's native token with a debit card or bank account. 
# Is there a way to limit or reduce gas fees?
High gas fees during heavy network usage times can be frustrating. Instead of paying a high gas fee, you can always:
1. __Choose another time.__ When gas fees are high, consider delaying your transaction until the network is less congested.
2. __Adjust your gas limit.__ Some apps and wallets allow users to adjust the gas fees they’re willing to pay. (But note that if you set your gas fee too low, your transaction may not go through.)
3. __Use a Layer 2 chain.__ An integral part of Ethereum’s scaling roadmap are Layer 2 networks like Unichain, Base, and Arbitrum, which are designed to execute transactions faster and at lower cost than Ethereum’s mainnet.

You can use several tools to check [current gas fees](https://etherscan.io/gastracker) and whether they are considered high at any given moment. 
# Don’t let gas fees slow you down
Gas fees keep the Ethereum network moving, so that your onchain activity is secure and seamless — whether you’re swapping tokens, minting NFTs and other collectibles, or exploring more advanced decentralized apps. 

__Need some ETH? Here are two easy ways to fill up your crypto wallet.__ First, [buy some ETH](https://blog.uniswap.org/web-fiat-on-ramp) using local currency with Uniswap Labs’ fiat onramp feature — available in the Uniswap web app or the Uniswap wallet app on mobile. Or [make a transfer](https://blog.uniswap.org/transfer-crypto-to-self-custody-wallet) from a centralized exchange like Coinbase or Robinhood. 

__Already have an ETH balance? It’s full speed ahead from here.__ Explore charts on Ethereum and more than dozen Ethereum-compatible Layer 2 networks, select a token, and make your very first swap. Connect your wallet to the [Uniswap web app](https://app.uniswap.org/?utm_medium=blog&utm_source=blog&utm_campaign=eth-gas-fees&utm_content=uniswap-web-app) and start swapping.

Ethereum and other blockchains collect network costs or “gas fees” on transactions. How much you’ll pay depends on several factors.
