# The Core of Multistake The zkSync Home Vault serves as the core settlement and accounting layer of the Multistake protocol. It is the only component authorized to mint or burn shares, compute `totalAssets()`, and determine the canonical net asset value (NAV). Every system operation — including deposits, withdrawals, strategy allocation, rebalancing, and profit-and-loss (PnL) reconciliation — ultimately resolves within this vault. All external execution environments operate subordinate to this accounting layer. The vault is an ERC-4626-compliant contract deployed on zkSync, leveraging zkSync’s low-cost execution, fast finality, and validity-proof security model to provide a highly reliable settlement environment. Its primary role is not to execute strategy logic, but to maintain provably correct and deterministic accounting across multiple blockchain environments that may differ in latency, execution guarantees, and failure domains. This strict separation of settlement and execution ensures that faults, delays, or adverse behavior in any external execution environment cannot compromise vault solvency, accounting integrity, or user-facing ERC-4626 semantics. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://multistake-1.gitbook.io/multistake-docs/documentation/zksync-home-vault/the-core-of-multistake.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
