TL;DR

A liquidity provider (LP) is anyone who deposits tokens into a DEX liquidity pool to enable trading. In return, they earn a share of the trading fees from every swap. During a token launch, the founder acts as the initial LP by depositing the liquidity portion of their budget alongside their token into the pool: this is what creates the market.

How It Works

A liquidity provider is the person who stocks the shelves of a decentralized exchange. Without LPs, there are no reserves to trade against, and the pool doesn’t function.

In practice, being an LP means depositing two tokens in equal USD value into a pool. For a TOKEN/USDC pool, you’d deposit $10,000 of TOKEN and $10,000 of USDC. The pool gives you LP tokens, receipts that track your percentage ownership of the total pool reserves. If you deposited 100% of the pool’s capital, you own 100% of the LP tokens.

Every time a trader swaps in the pool, a fee (commonly 0.3%) is charged and added to the reserves. Since you own a share of the reserves, your LP tokens now represent slightly more value. Over time, if the pool processes significant volume, these accumulated fees can be substantial.

For token launches, the founder is nearly always the first LP. Creating the pool means depositing the liquidity portion (L) of the TGE budget as the base asset, paired with a proportional amount of the newly minted token. This single act creates the market: it sets the initial price, establishes liquidity, and enables anyone in the world to buy or sell the token.

The tradeoff for LPs is impermanent loss. As the price ratio between the two tokens changes, the AMM rebalances the LP’s position, selling the appreciating asset and accumulating the depreciating one. For token launches, this is particularly relevant: if the token’s price increases substantially (the desired outcome), the founder’s LP position will underperform what they would have earned by simply holding the tokens and base asset separately.

This is why sophisticated launch planning considers the LP position not as a fixed deposit but as an active position with a known cost structure. The Token Launch Simulator models the founder as the initial LP and shows how the position evolves through the launch sequence.

Frequently Asked Questions

What does a liquidity provider do?

A liquidity provider deposits two tokens into a DEX pool (ETH and a new token, for example) in equal value. This creates the reserves that traders swap against. In return, the LP receives LP tokens representing their pool share and earns a portion of every trading fee. The LP can withdraw their share at any time by burning their LP tokens.

How do LPs make money?

LPs earn a percentage of every trade executed against the pool, typically 0.3% per swap in Uniswap v2-style pools. These fees accumulate in the pool reserves, increasing the value of LP tokens over time. Whether LPs profit overall depends on whether fee income exceeds impermanent loss from price changes between the paired tokens.

Is the founder always the first LP?

In a DEX-first launch, yes. Someone has to create the pool and deposit the initial reserves: that’s typically the founding team or treasury. The amount they deposit sets the initial liquidity and price. After launch, other LPs can add to the pool, but the founder’s initial provision is what enables the first trades.

What risks do LPs face?

The main risk is impermanent loss: if the price ratio between the two tokens changes significantly, the LP position underperforms simply holding the tokens separately. LPs also face smart contract risk (bugs in the pool contract) and the risk of the paired token losing value entirely. For token launch LPs specifically, there’s also the risk that low trading volume means fees don’t compensate for IL.
