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()

   • Number of subvaults via vault.subvaults()

2. Iterates over each subvault:

   • 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

     • Stops early if full amount has been distributed

Components and Assumptions

• Vault: Must implement IVaultModule:

  • subvaults() → number of subvaults

  • subvaultAt(index) → returns subvault address

  • hookPushAssets(subvault, asset, amount) → transfers tokens to subvault

  • riskManager() → returns associated IRiskManager

• Risk Manager: Must implement:

  • maxDeposit(subvault, asset) → returns max allowed deposit into that subvault
