Uniswap v2 opens in a new tab can create an exchange market between any two ERC tokens. In this article we will go over the source code for the contracts that implement this protocol and see why they are written this way. Basically, there are two types of users: liquidity providers and traders. The liquidity providers provide the pool with the two tokens that can be exchanged we'll call them Token0 and Token1. In return, they receive a third token that represents partial ownership of the pool called a liquidity token. Traders send one type of token to the pool and receive the other for example, send Token0 and receive Token1 out of the pool provided by the liquidity providers. The exchange rate is determined by the relative number of Token0 s and Token1 s that the pool has. In addition, the pool takes a small percent as a reward for the liquidity pool. When liquidity providers want their assets back they can burn the pool tokens and receive back their tokens, including their share of the rewards.

Seamlessly swap and provide liquidity on v2 on all supported chains directly through the Uniswap interface. With both v2 and v3 available across all supported networks, users have the flexibility to choose between simplicity with v2 and more advanced features with v3. While v3 offers advanced capabilities for more active liquidity providers LPs , v2 offers a more simple LP experience. Unlike v3, pools on v2 cover the entire price range of the pool by default — reducing the need for active management and monitoring as an LP. Users already save on gas fees when swapping with v3 on non-Ethereum chains. Plus, users benefit from almost no MEV on L2s, due to sequencers — particularly helpful for swapping longtail assets, which are more prone to losses due to MEV. For users looking to swap using v2, you can visit app. The Uniswap interface will route your swap through the version of the protocol with the best price which might be v2, but could also route through v3 or UniswapX.

You could call the core contracts directly, but that's more complicated and you might lose value if you make a mistake. If it is zero then there is no protocol fee and no need to calculate it that fee. Overall, there are more than 1, coins and tokens available for trading. Since it's a decentralized service, users can list tokens for trading without restrictions, as long as there is liquidity to support them. These state variables are necessary to implement the protocol fee see the whitepaper opens in a new tab , p. To create a new contract we need the code that creates it both the constructor function and code that writes to memory the EVM bytecode of the actual contract. The exchange rate is determined by the relative number of Token0 s and Token1 s that the pool has. In Uniswap 2. Access to storage is a lot more expensive than access to the volatile memory that is released when the function call to the contract ends, so we use an internal variable to save on gas. Here is a simple example.

Uniswap v2, the second iteration of the Uniswap protocol, has been deployed to the Ethereum mainnet! An audit report and formal verification has already been released and the Uniswap v2 Bug Bounty has been running for over a month.
