# Curve

> Liquidity provision on Curve Finance pools

## What this yield is

* **Protocol**: Curve Finance AMM
* **Networks**: Ethereum, Arbitrum, Optimism, Base, Polygon, Avalanche, Sonic
* **Receipt token**: Curve LP token (e.g., `3CRV`, `2CRV`, `stETH/ETH`)
* **Rewards**: Trading fees (reflected in LP token price appreciation)

<Note>
  Curve is a decentralized AMM optimized for efficient trading between assets with similar price behavior — stablecoins, LSTs, LRTs, and closely correlated tokens.
</Note>

## Pool types

<Tabs>
  <Tab title="Stablecoin pools">
    Pools for USD-pegged assets with minimal impermanent loss.

    Examples: USDC/USDT, crvUSD/stables, 3CRV (DAI/USDC/USDT)
  </Tab>

  <Tab title="LST/LRT pools">
    Pools for liquid staking and restaking tokens pegged to ETH.

    Examples: stETH/ETH, frxETH/WETH, rETH/wstETH, ezETH/WETH
  </Tab>

  <Tab title="Meta-pools">
    Pools referencing other LP tokens for deeper liquidity.

    Examples: LUSD/3CRV, FRAX/3CRV, MIM/3CRV
  </Tab>

  <Tab title="Tricrypto">
    Multi-asset pools combining USD, BTC, and ETH exposure.

    Examples: TricryptoUSDC, TricryptoUSDT, TricryptoLLAMA
  </Tab>

  <Tab title="BTC pools">
    Pools for Bitcoin-pegged assets.

    Examples: tBTC/WBTC, renBTC/WBTC, cbBTC/WBTC
  </Tab>
</Tabs>

## How it works

<Steps>
  <Step title="Add liquidity">
    Deposit one or more pool assets into a Curve pool
  </Step>

  <Step title="Receive LP token">
    Get the Curve LP token representing your pool share
  </Step>

  <Step title="Earn fees">
    Trading fees accrue via LP token price appreciation (price-per-share)
  </Step>

  <Step title="Remove liquidity">
    Burn LP tokens to receive underlying assets plus earned fees
  </Step>
</Steps>

## Required inputs

| Parameter | Description                    |
| --------- | ------------------------------ |
| `yieldId` | The specific Curve LP yield ID |
| `address` | User's wallet address          |
| `amount`  | Amount to deposit              |

## Pending actions

None. Trading fees accrue automatically to LP token value.

## Key considerations

<AccordionGroup>
  <Accordion title="Impermanent loss">
    Curve pools are LP positions. Users are exposed to relative price movements between pool assets. Even stablecoin pools carry IL risk if one asset depegs.
  </Accordion>

  <Accordion title="Multi-asset deposits">
    Some pools are 2-asset (USDC/USDT), others are N-asset (3pool, 4pool), and some are meta-pools (LUSD/3CRV). Users can deposit all available assets or a single asset.
  </Accordion>

  <Accordion title="APY variability">
    APY depends on trading volume. High-volume periods generate more fees; quiet periods generate less. APY is not fixed.
  </Accordion>

  <Accordion title="Gauge rewards">
    Some pools have gauges offering additional CRV rewards. Check individual pool details for incentive availability.
