Wealth3 is a deads-man switch protocol, that allows users to lock ETH and get yield, and uses it to run validator nodes on Ethereum.
Users can set up the fund lockup duration, and how much time should run by until they are considered inactive. It also lets them set up trusted wallets that should receive the funds in case the user goes inactive. This situation would trigger the distribution of their funds to their trusted wallets.
Proof of life is achieved by depositing Ether into the fund or by executing a method on the contract. Users will get reminded to interact with the contract via Push protocol. After the time is due, users will receive their funds and yield interest from running the node. The protocol keeps 1% of the yield generated as an asset management fee.
