Lido announced the launch of the Ethereum Staking SDK, a TypeScript library for building off-chain integrations. The SDK allows developers to seamlessly integrate Lido staking into off-chain applications, providing core features such as staking, reward tracking, withdrawal, and packaging. The newly released SDK features multi-chain support, allowing cross-chain staking/unstaking operations on networks such as OP Mainnet. The tool includes pre-built methods and full documentation for developing DeFi protocols, dashboards, or new staking products.
