Uniswap Labs releases two new smart contracts: Permit2 and Universal Router

11/18 01:47

Today, Uniswap Labs has released two new smart contracts: 1. Permit2 allows token approvals to be shared and managed across different applications creating a more unified, cost-efficient, and safer UX. 2. Universal Router unifies ERC20 and NFT swapping into a single swap router. Integrated with Permit2, users can swap multiple tokens and NFTs in one swap while saving on gas fees. Permit2 and Universal Router are non-upgradable, unowned, and open-source contracts that have been deployed to the same address across Ethereum, Optimism, Arbitrum, Polygon, and Celo.
