🧾 LP Tokens Liquidity Provider Tokens
When you deposit a pair of assets into a liquidity pool on a DeFi exchange, the protocol mints you LP tokens in return. They are a receipt that proves your share of the pool, and burning them gives back your assets plus your cut of the trading fees.
🎟️ The simple version — a coat-check ticket
Picture handing two coats to a coat-check counter and getting one numbered ticket back. The ticket is not the coats, but it is the only thing that proves the coats are yours. That ticket is an LP token. You deposit a pair of assets into a liquidity pool, the protocol hands you LP tokens, and those tokens record your proportional share of everything in the pool. When you want out, you give the tokens back (this is called burning them) and receive your assets again, plus your slice of the fees the pool collected while you were in it.
⚙️ Where the fees come from
A liquidity pool prices trades with an automated market maker, classically the constant-product formula x · y = k that Uniswap made famous. Every trader who swaps against the pool pays a small fee, and that fee flows to the people who supplied the assets. Holding LP tokens is how you stake your claim to that stream of fees on a decentralized exchange.
🧩 Why they are more than a receipt
LP tokens are composable, which means other DeFi apps can use them too. You can stake them in a yield farm to earn extra rewards, post them as collateral for a loan, or simply transfer them to hand pool ownership to someone else. The receipt itself becomes a building block.
| What you do with them | What it means |
|---|---|
| 🔥 Burn (redeem) | Return the tokens to the pool and reclaim your assets plus earned fees |
| 🌾 Stake in a yield farm | Deposit LP tokens elsewhere to earn additional rewards on top of pool fees |
| 🤝 Transfer | Send the tokens to another wallet to pass on the claim to the pool |
📊 Forms differ by protocol: PancakeSwap gives pair tokens like CAKE-BNB, SushiSwap uses ERC-20 LP tokens, and Uniswap v3 issues each position as an NFT.
🚨 Things beginners should know
- 📉 Impermanent loss — If the prices of the two paired assets drift apart, you can end up worse off than if you had just held them. The loss locks in the moment you withdraw
- 🐛 Smart-contract risk — The pool is code. A bug or exploit in that code can drain the assets, and no one can reverse it
- 🔑 Lost token, lost assets — The LP token is your only proof of claim. If it is lost or stolen, the underlying assets are gone with it, permanently
- 🚪 Exit through the right door — Always redeem at the protocol you deposited into; do not try to sell LP tokens on a random swap
❓ FAQ
- Can I sell my LP tokens like any other token?
- You shouldn't. They are a claim receipt, not a tradable coin. Selling them on a random swap usually returns a tiny fraction of their value, and on-chain that loss can't be undone. The right exit is to redeem (burn) them through the same protocol where you deposited.
- What happens if I lose my LP tokens?
- You lose access to the assets in the pool. The LP token is the proof of your claim, so if it's lost or stolen, your deposited assets are gone with it. Think of it like a coat-check ticket: lose the ticket and you can't get your coats back.
- Is impermanent loss really temporary?
- Not really. The name is misleading. As long as you stay in the pool the loss is only on paper, but the moment you withdraw it becomes permanent. It is the gap between what you ended up with and what you'd have had by simply holding the two assets.
