## Contracts this launch creates

Send the transaction to HoodieCreate v5 `0x3CDB4956CD35F8b865cc3E682a10906773DBe1Df`. For the salt and creator above, the created contracts are:

| Contract | Address |
|---|---|
| Fee vault V11 | `0xBc9Fcc4Dd4fDAe4Deb70F318b6984489879574f0` |
| Cost escrow V5 | `0x0BffA90dD6f0B2274Bc4E7358783d2Facfbb7f7a` |
| Whale budget V5 | `0xd60cBA3e2Ace9D2dD666d7CccDd114B1f4060207` |
| Distribution factory | `0xd67D2EBA0D3172D43DBe41F76a7bD85357F9d1C5` |

The reward reserve address is created inside the same transaction. The token address is in the `Launched` event on HoodieCreate.

`expectedEconomics` must match `previewLaunchEconomics(0, 0x0000000000000000000000000000000000000000)` on the factory at the moment of the launch. If that call returns a different bytes32, use the new one. The vault, cost escrow, and whale addresses stay the same as long as the creator, salt, tax, split, and pair stay the same.
