This sequence of actions demonstrates how the Swaps.io system handles the withdrawal of collateral. It includes the preparation for the withdrawal, the withdrawal itself, and the verification of the withdrawal.

1. **Preparation**:
   1. `CollalteralManager` emits a `WithdrawReport` event, signaling that it is prepared for the withdrawal of collateral.
   2. The Intent Agent sends an unlocking transaction by calling the `reportWithdraw` method of the `CollalteralManager` contract in the receive chain to prepare a withdrawal.
   3. `CollalteralManager` increases the amount of locked collateral by the order amount. Locked collateral is the amount of collateral that is currently locked and cannot be used for other orders.
2. **Withdrawal**:
   1. The Intent Agent instructs the `CollateralManager` to withdraw collateral, calling method `withdraw` and providing `reportProof`.
   2. `CollateralManager` checks to make sure the amount being withdrawn does not exceed the amount of locked collateral. If it does, the withdrawal is rejected.
   3. `CollateralManager`, with the help of Light Clients, verifies the proof of the `Withdraw` event provided with `reportProof`. If the proof is falsified, the withdrawal is rejected.
   4. `CollateralManager` decreases the total amount of collateral to reflect the withdrawal and updates its own state to reflect the new total amount.
   5. `CollateralManager` emits a `Withdraw` event, signaling that the withdrawal of collateral has occurred.
