# Renew Territory

Used for user renewal of territory transactions. After the user has minted a territory, this transaction can be called to extend the expiration date of a certain territory. `days` indicates the number of days for renewal. The fee paid depends on the renewal time and the space size of the current territory. Use the territory name to specify which territory.
