- This protocol is susceptible to risks related to decentralized exchanges (DEXs), such as impermanent loss
- Uniswap is one of the most copied protocols in DeFi as it pioneered the concept of automated market makers (AMMs), as well as the concept of concentrated liquidity (Uni V3) that lets you choose your own price range to provide liquidity
How Uniswap V3 works
Uniswap V3 is an automated market maker (AMM) that introduces the concentrated liquidity model. Concentrated liquidity is a new AMM model where liquidity is allocated within a custom price range. Previously in V2, liquidity was distributed between 0 and infinity, uniformly along the price curve. V3 allows liquidity providers (LPs) to concentrate their capital on smaller price intervals or ticks. This offers traders deeper liquidity and allows LPs to earn more with less capital required. However, this also increases impermanent loss as rising and falling asset prices can result in the position's liquidity being out of range (e.g. position is fully one asset) and no longer earning fees.
How Uniswap V3 makes money
Uniswap makes money via protocol fees that can be optionally turned on by UNI holders through a community governance proposal. Whenever a liquidity pool is created, protocol fees are set to 0 by default. Uniswap could then receive a fraction of these transaction fees. Currently, the protocol does not charge protocol fees and all fees are earned by liquidity providers.
How you make money on Uniswap V3
In order to incentivize users to create trading markets on their platform, Uniswap must pay these users who are providing liquidity into these pools in the form of swap fees. Uniswap currently distributes all of the swap fees earned for each pool directly to the liquidity providers that is proportional to the amount they deposited. For Uniswap V3, the fee tiers charged for every transaction are 0.01%, 0.05%, 0.30%, or 1% depending on the specific pool.
