AssetVault

_During the normal operation time, only Metahub contract is allowed to initiate asset return to the original asset owner. In case of emergency, the vault admin can switch vault to recovery mode, therefore allowing anyone to initiate asset return.

NOTE: There is no way to transfer asset from the vault to an arbitrary address. The asset can only be returned to the rightful owner.

Warning: All tokens transferred to the vault contract directly (not by Metahub contract) will be lost forever!!!_
