Function: addBurnFeeRequest(uint256 assetID, OrderInfo orderInfo)

The function is used to add a burn-fee request for a given asset.

Inputs

• assetID

  • Control: Fully controlled by the caller.

  • Constraints: The contract is checked to be a fee manager of the asset.

  • Impact: A non-manager cannot create a burn request.

• orderInfo

  • Control: Fully controlled by the caller.

  • Constraints: The order should not have been used before for the asset swap. The order hash should match the hash computed over the order structure. The signature of the order is verified to have been made by the order maker.

  • Impact: Prevents invalid order from being passed or replayed to the same swap.
