Permit2 and Universal Router, two new smart contracts, were made available by Uniswap Labs.
The token approval contract Permit2 enables secure token approval management and sharing across many smart contracts.
The contract can standardize token approvals across all apps as more projects link with Permit2. It will enhance the user experience by lowering transaction costs while enhancing the security of smart contracts.
Permit2 allows token approvals to be shared and managed across different applications creating a more unified, cost-efficient, and safer UX.
Next-generation router from Uniswap that combines token and NFT exchanges into a highly adaptable, gas-optimized, secure, and extensible swap router is called the Universal Router. It will soon replace all other swap routers as the standard swap router for all Uniswap swaps since it dramatically enhances both the product and user experience.
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.
DeFi is constantly innovating to attract users, the recent continuous problems of CEX exchanges have helped it develop more, but in any financial industry, there are many potential risks. Yesterday, the Uniswap website interface was stuck in the system, confusing many users.
