According to online reports, Lido announced the launch of the Ethereum Pledge SDK, a TypeScript tool library for building offline integration. The SDK allows developers to seamlessly integrate Lido pledge functions into offline applications, providing core functions such as pledge, reward tracking, cash withdrawal and packaging. The newly released SDK has multi-chain support features, allowing pledge/de-pledge operations on networks such as OP Mainnet that do not require cross-chain. The tool includes pre-built methods and complete documentation that can be used to develop DeFi protocols, dashboards, or new pledge products.
