An LP (Liquidity Provider) token is the receipt token issued to users who deposit assets into an AMM liquidity pool. It represents your proportional share of the pool and accrues trading fees automatically. Redeeming your LP tokens returns your share of the pool's assets at the current ratio.
LP tokens are one of DeFi's most fundamental primitives — they transform a claim on pooled liquidity into a tradeable, composable token that can be used across the broader DeFi ecosystem.
**How LP tokens work:**
When you deposit assets into an AMM pool, the protocol mints LP tokens representing your share: - Uniswap v2 pools issue UNI-V2 tokens (ERC-20) - Curve pools issue curve LP tokens (e.g., 3CRV for the 3Pool) - Balancer pools issue BPT (Balancer Pool Tokens)
The LP token represents a fractional claim on all the assets in the pool. As trading fees accumulate, the pool grows. Since your LP token represents a fixed percentage of the pool, it automatically accrues a growing share of the total pool value.
**Redemption mechanics:**
To exit a pool, you burn your LP tokens in exchange for the underlying assets. You receive your proportional share at the current pool ratio — which may differ from the ratio you deposited at (due to AMM rebalancing and impermanent loss).
**LP token composability (money legos):**
LP tokens are where DeFi composability shines. Instead of sitting idle, LP tokens can be: - **Staked in yield farms:** Many protocols accept LP tokens as staking deposits and pay additional token rewards on top of fee income - **Used as collateral:** Lending protocols like Abracadabra accept LP tokens (e.g., Curve LP tokens) as collateral for borrowing stablecoins - **Deposited into Curve gauges:** LP tokens deposited into Curve gauges earn CRV rewards proportional to gauge weight - **Wrapped into vault tokens:** Yearn and Beefy accept LP tokens and auto-compound the yield
**Uniswap v3 NFT LP positions:**
Uniswap v3 broke the standard LP token model — because each position has a custom price range, positions are non-fungible. Instead of ERC-20 tokens, Uniswap v3 positions are represented as ERC-721 NFTs. This makes v3 positions less composable than v2 (you can't easily use a v3 NFT position as collateral), though wrapper protocols like Arrakis have solved this by aggregating positions.
**Risks of holding LP tokens:** - Smart contract risk in the underlying pool - Impermanent loss reducing redemption value - Liquidity risk if pool TVL falls sharply - Potential exploit of composability — if a protocol accepting LP tokens as collateral has a bug, your LP tokens could be at risk

Frequently Asked Questions
Can I sell my LP tokens on secondary markets?
ERC-20 LP tokens can technically be transferred and traded on secondary markets, but in practice most LP tokens have thin secondary liquidity. Most LPs simply burn their tokens against the protocol to redeem. Uniswap v3 NFT positions can be listed on NFT marketplaces like OpenSea, but this is rare. The most practical secondary market for LP exposure is buying vault tokens (e.g., Yearn's yTokens) that represent managed LP positions.
What happens to LP tokens during a protocol exploit?
If a pool is exploited and drained, LP tokens lose most or all of their value — there are no assets left to redeem. This is the primary risk of providing liquidity: LP tokens are only as valuable as the underlying pool's security. Well-audited protocols and protocols with active bug bounties offer higher assurance, but no smart contract is fully exploit-proof.
Do LP tokens always represent a 50/50 split?
No. Standard Uniswap v2 pools are 50/50 by value, but other AMM designs differ. Balancer allows arbitrary weightings (80/20 ETH/DAI, for example), which reduces impermanent loss for the heavier-weighted asset. Curve pools can have three or more assets (the 3Pool: USDC/USDT/DAI). The LP token represents your fractional claim on whatever ratio the pool currently holds.

Impermanent Loss
Impermanent loss (IL) is the reduction in value a liquidity provider experiences compared to simply holding the same assets. It occurs because AMM rebalancing forces LPs to sell the appreciating asset and buy the depreciating one — the opposite of optimal holding behavior. IL becomes permanent if the LP withdraws before prices revert.
Constant Product Formula (x*y=k)
The constant product formula x*y=k is the mathematical invariant underlying Uniswap v1/v2 and most early AMMs. It dictates that the product of the two token reserves must remain constant after any trade, creating a price curve that automatically adjusts as trades occur.
Concentrated Liquidity (Uniswap v3)
Concentrated liquidity allows AMM liquidity providers to allocate capital within a specific price range rather than across the entire price curve. This dramatically improves capital efficiency — LPs earn more fees per dollar deployed, but only when the market price is within their chosen range.
Auto-Compounding in DeFi
Auto-compounding is the process of automatically reinvesting yield rewards back into the principal to earn compound returns. DeFi vaults and yield aggregators auto-compound by collecting reward tokens, selling them for more of the underlying asset, and redepositing — transforming APR into a higher effective APY.
