Lido Staking Vaults (stVaults): Technical Design and Architecture Disclaimer! This is a living Work-in-Progress draft of the Lido stVaults technical design document. It outlines the core design principles, architecture, and mechanics at a high level. It's not a product specification or goals document—though those are briefly referenced for context. Detailed technical reference materials will follow in subsequent documents. 1. Abstract Lido Staking Vaults (stVaults) are modular primitives that connect stakers, node operators, and protocols—enabling them to define custom fee structures, tailor validator configurations, and fine-tune risk/reward. This flexibility is achieved without compromising decentralization, security, or access to stETH liquidity.
