Uniswap Labs Releases Permit2 and Universal Router

Uniswap Labs announced the release of two new smart contracts, Permit2 and Universal Router.

Permit2 allows token approvals to be shared and managed across different applications creating a more unified, cost-efficient, and safer UX.

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.
