## When should I deploy a Vault IAM?

* For streaming rewards: If you want to “stream” incentives, prorated among depositors.
* For ERC-4626 actions: If you currently use ERC-4626 Vaults or can easily configure your system.

## When should I deploy a Recipe IAM?&#x20;

* For lump sum rewards: If you want to pay a lump sum, paid per depositor.
* For actions that are not ERC-4626 actions: If the action I wish to incentivize cannot be represented as an ERC-4626 Vault.
* For actions with timelocks: If you wish for depositors to timelock their position/assets.

For IP conditional offers: If you wish to counter-offer for incentives as an IP.
