Lido announces the launch of the Ethereum staking SDK, a TypeScript toolkit for building off-chain integrations. This SDK enables developers to seamlessly integrate Lido's staking features into off-chain applications, providing core functionalities such as staking, reward tracking, withdrawals, and wrapping. The newly released SDK has multi-chain support features, allowing staking/un-staking operations on networks like OP Mainnet without cross-chain requirements. This tool includes pre-built methods and comprehensive documentation, suitable for developing DeFi protocols, dashboards, or new staking products.
