## Content

Optimism expanded its Actions SDK, evolving it from an early developer preview into a more complete framework for embedding DeFi directly into applications. The updated SDK introduces fully integrated onchain financial actions, allowing users to lend, earn yield, swap tokens, and make payments without needing external wallets. The Actions SDK supports lending through Aave and Morpho, and token swaps via Uniswap and Velodrome, with built-in routing and liquidity handling. A standardized action interface unifies all operations under a consistent structure, reducing integration complexity. The expansion deepens wallet infrastructure, adding embedded wallet integrations via Privy, Turnkey, and Dynamic, with support for EOAs, smart wallets, bundlers, and paymasters. The SDK enables multi-chain DeFi experiences across OP Stack chains.Disclaimer: Content is for informational purposes only, not endorsement or investment advice.
