# TokenizedShareManager ### Overview * This module extends `ShareManager` and `ERC20Upgradeable`, making vault shares externally transferable and fully compliant with the ERC20 standard. * It is intended for vaults that require tokenized shares usable across external protocols, wallets, or DeFi integrations. * Core share logic (minting, burning, whitelisting, lockups) is delegated to the inherited `ShareManager`, preserving consistent permission enforcement. * Whitelist enforcement, lockup mechanics, and share claim logic are integrated into the overridden `_update` hook, which ensures all token transfers pass necessary checks and call `claimShares` for non-zero actors. * Suitable for use cases where share liquidity, composability, or token standard compatibility (e.g., ERC20, ERC4626 wrappers) is required. --- # 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.
