About
The problem it solves Crypto funds stored in Blockchain Wallets might be frozen for eternity when the owner dies. As any other assets they should be passed on to the respective heirs as defined in the last will. ETVault allows owners of crypto assets stored in a Gnosis Safe to make their will on the blockchain and make sure that all inheritors get their share as defined.
How it's made
Challenges we ran into Figuring out, how transactions in Gnosis Safe can be controlled externally. We need to set up a Guard - which is actually a defined filter for transactions - which blocks the access to the assets while the owner is still among us and grants the to heirs after death. One of the challenges was to find out how to prevent the heirs - who should be granted access to the Safe - from just removing the Guard. Working with Solidity due to missing knowlage. Working with the wagmi library was a bit tricky at times. The fact what we had low resources on everything and that we just started to write actual code on saturday morning. Shots at midnight.
