RedirectingDepositHook

Overview

RedirectingDepositHook is a deposit time liquidity allocation hook implementing the IHook interface. It is designed to redirect newly deposited assets from a vault into its underlying subvaults, based on per-subvault risk and capacity constraints defined by a RiskManager.

This hook helps distribute liquidity optimally during deposit flows.

Purpose

• Automatically forwards newly deposited assets from the main vault into eligible subvaults.
• Delegates decision-making to the vault's configured RiskManager, which determines per-subvault deposit limits.
• Ensures that subvaults do not exceed their capacity constraints.

Key Function

callHook(address asset, uint256 assets)

Distributes a given amount of asset across available subvaults based on their individual deposit capacity.

Execution Logic:

1. Retrieves active vault context via IVaultModule(address(this)), configured RiskManager via vault.riskManager(), and the number of subvaults via vault.subvaults().
2. Iterates over each subvault and fetches max allowed deposit via riskManager.maxDeposit(subvault, asset). If allowed amount is zero, skip. Otherwise, pushes min(assets, allowed) via vault.hookPushAssets(), decrements assets accordingly, and stops early if the full amount has been distributed.

Components and Assumptions

• Vault must implement IVaultModule and support subvaults(), subvaultAt(index), hookPushAssets(subvault, asset, amount), and riskManager().
• Risk Manager must implement maxDeposit(subvault, asset) to return max allowed deposit into that subvault.
