Because Ethereum transactions occur in an adversarial environment, smart contracts that do not perform safety checks can be exploited for profit. UniversalRouter integrates with Permit2, to enable users to have This repository contains routing logic for the Uniswap V3 protocol. Today, Uniswap Labs has released two new smart contracts: Permit2 allows token approvals to be shared and managed across different applications creating a more unified, cost-efficient, and safer UX. UniversalRouter integrates with Permit2, Uniswap Contract Deployments. In order to deploy this code to a local testnet, you should install the npm package @uniswap/v3-periphery and import bytecode imported from Check out the whitepaper to learn more on how liquidity and ticks work in Uniswap V3.

Uniswap has an open and ongoing bug bounty program. While the underlying architecture uses a callback system for swaps, developers can still use the Universal Router to execute swaps on v4 pools, just as you would for v2 or v3. The UniversalRouter contract is the current preferred entrypoint for ERC20 and NFT swaps, replacing, among other contracts, SwapRouter02. Universal Router unifies ERC20 and NFT swapping into a single swap router. Next, select the network drop-down in the upper right hand of the screen. Integrators should no longer assume that they are deployed to the same addresses across chains and be extremely careful to confirm mappings below. Penn Blockchain) is creating this proposal in partnership with Matter Labs to Deploy Uniswap V3 on zkSync. Our routing guide will There are several things to unpack here. When integrating Uniswap V2 into another on-chain system, particular care must be taken to avoid security vulnerabilities, avenues for manipulations, and the potential loss of funds. The examples below are implementations of the two styles of multi-hop swapping available on v3. The pages here contain guides and technical documentation for the Uniswap V3 Smart Contracts.
