type SupplyLimit struct {
	Limit          sdk.Int       `json:"limit" yaml:"limit"`                       // the absolute supply limit for an asset
	TimeLimited    bool          `json:"time_limited" yaml:"time_limited"`         // boolean for if the supply is also limited by time
	TimePeriod     time.Duration `json:"time_period" yaml:"time_period"`           // the duration for which the supply time limit applies
	TimeBasedLimit sdk.Int       `json:"time_based_limit" yaml:"time_based_limit"` // the supply limit for an asset for each time period
