yield-vault-patterns

To prevent first-depositor attacks in an ERC-4626 vault, implement virtual shares and assets alongside safe initialization logic. This pattern mitigates early-depositor exploits by ensuring robust share math and capital efficiency from the very first deposit.

ERC-4626 share math calculations should use vault-favorable rounding rules to protect existing depositors. The pattern applies precise rounding during deposit, mint, withdraw, and redeem flows to ensure shares are rounded down for minting and up for burning.

A complete ERC-4626 tokenized vault implementation covers deposit, mint, withdraw, and redeem flows with automated share accounting. It aligns to the ERC-4626 standard, managing asset deposits and withdrawals while updating share prices accurately.

No external dependencies are required to build a yield-bearing vault with tokenized shares using this pattern. It provides a self-contained template for share math, asset management, and withdrawal logic that you can deploy directly with a test asset.

Inaccurate share pricing for early depositors in yield aggregator vaults is typically caused by missing virtual-share protection. Without safe initialization and vault-favorable rounding rules, first-depositor attacks can exploit share math to dilute subsequent deposits.
