Curve Fi

  • DEX running on Ethereum
  • Designed for swapping (directly) between stablecoins so as to reduce slippage as is the case w/ Uniswap (e.g. 500 USDC = 494.32 DAI)
  • uniswap for stablecoins” as it can be extremely useful for swapping between tokens that remain in a relatively similar price range (e.g. stablecoins or wrapped tokens like WBTC, renBTC, etc.)

Liquidity Pools (LP) in Curve

A liquidity pool is a smart contract holding pools of tokens (e.g. DAI and USDC) w/ a set ratio between the two (e.g. 1:1). If a trader comes and exchanges one for the other, the pool would become unbalanced forcing the exchange fee to go up (e.g. according to the AMM formula).1

LP recieve high APR because the pools are supplied to Compound to generate interest in combination to the fees when people trade.

How it Works

  1. Deposit coin (e.g. 100 USDC)
  2. Coin gets split up according to the reserves, so now you have 4 DAI, 30 USDC, etc. You’d get a bonus depositing the smallest reserve currency (i.e. DAI in this example) or withdrawing the largest currency (e.g. USDC in this example)
    DAI: 300k (4%)
    USDC: 2M (30%)
    ...
