Sarcophagus is an autonomous and incentivized dead man's switch application built on Ethereum and Arweave. The protocol works by giving a person a series of actions to complete in order to verify they are alive. If the person does not perform the actions, the deadman's switch will be triggered. When creating their "sarcophagus", a user provides the Ethereum address that will access a file when the protocol is triggered, as well as a recipient's public address and the date to try opening the sarcophagus. Sarcophagus was incubated by Decent Labs.
