SelfDestructible¶
Description¶
SelfDestructible allows an inheriting contract to be destroyed by its owner, who must announce an intention to destroy it, and then wait for a four week cooling-off period before it can be destroyed. Any ether remaining in the contract at this time is forwarded to a nominated beneficiary.
