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.

Uniswap v2 is divided into two components, a core and a periphery. This division allows the core contracts, which hold the assets and therefore have to be secure, to be simpler and easier to audit. All the extra functionality required by traders can then be provided by periphery contracts.

In this article, we will answer some of the most common questions about Uniswap V2 and its features. What is Uniswap V2 and how does it work? Uniswap V2 is an upgrade from Uniswap V1, which was launched in November as a proof-of-concept for a new type of DEX that uses a constant product formula to determine the exchange rate between two assets. This enables more diverse and efficient liquidity pools, as well as better prices for traders.

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. Developers can begin building on Uniswap v2 immediately! Initial docs and example projects are already available. For full details on the benefits of Uniswap v2 for liquidity providers and traders, please read the Uniswap v2 announcement blog post. For more information on the launch please read below. The migration portal makes the process of withdrawing liquidity from Uniswap v1 and depositing it into Uniswap v2 fast and simple.

Uniswap V1 was the proof-of-concept for a new type of decentralized marketplace. As a venue for pooled, automated liquidity provision on Ethereum, the Uniswap protocol Uniswap functions without upkeep, providing an unstoppable platform for ERC20 token conversion. Uniswap V1 will continue to work for as long as Ethereum exists , and so far, it has worked very nicely for a wide variety of use cases. However, pooled automated liquidity remains nascent technology, and we have only just begun to realize its potential. For this reason, last year we raised a seed round and formed a dedicated team to research and develop Uniswap alongside the broader Ethereum community. Uniswap V2 is our second iteration of Uniswap and includes many new features and improvements. This article will serve as a high-level overview of these changes including:. Since ETH is the most liquid Ethereum-based asset, and does not introduce any new platform risk, it was the best choice for Uniswap V1. If two ERC20 tokens are not paired directly, and do not have a common pair between them, they can still be swapped as long as a path between them exists. Router contracts can be used to optimize between direct and multi-step swaps.

The simplest case of removing liquidity. Instead we calculate the optimal number of A tokens for the desired amount of B tokens. Both V2 and V2 offer game-changing protocols. This hash is the identifier for the transaction type opens in a new tab. They are also the maximum amounts of A and B to be deposited. We use cookies to offer you a better browsing experience. This is a long article of about 50 pages. Try again with a different term. Ranked in DEX: 2. There is no need to specify how many ETH the user wants to deposit, because the user just sends them with the transaction the amount is available in msg. If you made it here, congratulations! If the transaction cannot take place with these amounts or more, revert out of it. If not, send it to the next pair exchange. Uniswap V2 is a relatively new and experimental protocol that involves several risks for both traders and liquidity providers, such as: Smart contract bugs: Uniswap V2 is based on a set of smart contracts that have been audited and tested by reputable security firms and experts, but there is still a possibility of undiscovered bugs or vulnerabilities that could compromise the functionality or security of the protocol.

Uniswap is an automated liquidity protocol powered by a constant product formula and implemented in a system of non-upgradeable smart contracts on the Ethereum blockchain.

Transfer fee tokens are pretty rare, so while we need to accommodate them there's no need to all swaps to assume they go through at least one of them. Instead, the liquidity migrates between each version to ensure continuous access to the resources. The kLast state variable is located in storage, so it will have a value between different calls to the contract. Market 24h volume. If so, send the tokens received for the trade to the destination. Now that they have been migrated, it is no longer relevant. This function returns the reserves of the two tokens that the pair exchange has. Oracle manipulation can be prevented by using longer time intervals for querying the oracle, or by using other sources of price information. Forks -. That number can still be encoded as a UQx
