Uniswap is a place where developers, liquidity providers and traders converge to participate in an open and accessible financial marketplace. It is a Decentralized Finance project that gives control of the assets in the hands of its users. There is no central order book to match buyers or sellers but Liquidity Pools where liquidity is provided by liquidity providers.
With over 128 million all-time trades and a trading volume of more than $1.3 trillion, Uniswap(V3) is the largest decentralized cryptocurrency exchange as per CoinMarketCap data.
What is Uniswap?
Uniswap is a Decentralized Finance(DeFi) protocol built on the Ethereum blockchain. It was developed by Hayden Adams based on the idea of an Automated Market Maker(AMM) and launched in 2018. This open-source project uses smart contracts to enable peer-to-peer trades and ERC-20 token swaps.
Uniswap’s native coin is called UNI and it is an ERC-20 token. UNI token holders can vote for changes to the Uniswap protocol. This essentially establishes community ownership over the Uniswap protocol.
How does Uniswap Work?
Uniswap is a decentralized protocol. This means that there is no central entity controlling the order books or holding the customers’ assets on their behalf. Instead, Uniswap uses a model known as Automated Market Maker(AMM). An AMM is a collection of smart contracts that spell out how liquidity is to be provided, how liquidity pools are to be created and how assets are to be swapped.
A liquidity pool is an aggregation of digital assets locked in a smart contract. Uniswap uses the formula X*Y=K to determine the price of the tokens in the pool. Here, X and Y are the two tokens in the pool.
The people who provide liquidity to a pool are known as liquidity providers(LPs). They are compensated for staking their assets either by being given crypto or a percentage of the transaction fee charged. On Uniswap, LPs get a portion of the fee charged for swapping tokens in proportion to their contribution.
