Lido announces the launch of an Ethereum staking SDK, a TypeScript tool library for building off-chain integrations. This SDK allows developers to seamlessly integrate Lido's staking features into off-chain applications, providing core functions such as staking, reward tracking, withdrawal and wrapping. The newly released SDK has multi-chain support features that allow for non-cross-chain staking/unstaking operations on networks like OP Mainnet. The toolkit includes pre-built methods and complete documentation suitable for developing DeFi protocols, dashboards or new types of staking products.
