Uniswap Web App to Support 7,702 Smart Wallets with Pectra Upgrade

Uniswap has introduced a new recipient parameter in its Trading API, expanding functionality for developers building payment and transfer solutions. **Key Features:** - Enables checkouts, payouts, and cross-asset transfers - Allows tokens to be sent directly to specified recipients - Supports flexible payment flows beyond standard wallet-to-wallet swaps **Developer Impact:** The update gives developers more control over token routing, making it easier to build applications that require sending assets to third parties or implementing payment systems. Full technical documentation is available on the [Uniswap Developer Portal](https://developers.uniswap.org/docs/changelog/active-notifications/recipient-parameter-on-trading-api).

Uniswap has removed all interface fees on its Web App and Wallet, making it one of the most cost-effective platforms for token swaps. **Key Changes:** - Zero interface fees now active across Uniswap's web and wallet applications - Users only pay network gas fees and liquidity provider fees - Applies to swaps on Uniswap V2, V3, and V4 protocols This move eliminates an additional cost layer that some DEX interfaces charge, potentially saving users money on every transaction. The change positions Uniswap as a more competitive option in the decentralized exchange landscape.
