King's Vault — Protocol Documentation

King's Vault is a permissioned, cross-chain yield aggregator built on the ERC-4626 Tokenized Vault Standard. It accepts Stablecoin deposits on Ethereum Mainnet and deploys capital into DeFi protocols across Ethereum and Hyperliquid (HyperEVM / HyperCore).

This documentation serves as the canonical technical reference for smart-contract auditors, integrators, and protocol operators.
