Usage

Check	Token contract	Owner	Spender
Deposit token approval	Deposit token (e.g., USDC)	User’s address	`vault.communityCodeDepositorModuleId` (DistributorCodeDepositor)
Account share approval	BoringVault	User’s address	`vault.withdrawQueueModuleId` (WithdrawQueue)

If the returned allowance is less than the amount you intend to deposit or withdraw, you need to call approve() first. See the Deposits or Withdrawals guides for the full flow. Contract addresses are obtained via Account Discovery.
