Here are the three hardest jobs for this "Family Crypto Wallet":
1- Shared Keys (Control for Today): The money needs to be locked in a "shared safe" that requires two out of three family members to agree to open it (this is called "multi-sig"). The design must make sure the keys can be updated easily if someone loses their phone or a key is forgotten.
2- Passing the Money to the Children (Inheritance): How will the wallet work 20 years from now, when the children need the money? It must be simple for someone who is not a crypto expert to claim the assets. It should feel like a simple bank transfer, not a technical puzzle.
3- Working on Many Digital Roads (Multi-Chain): Families hold different coins on different digital networks (like Bitcoin, Ethereum, and the XRP Ledger for fast, low-fee projects). The wallet has to connect to all of these different networks, which is messy for the developers who build it.
I know that multi-chain part is a real headache. It's the kind of complex challenge that platforms like Lumos Core are built to solve.
If you are the designer, I would ask: Which network is the best digital "contract" (digital will) to use for the inheritance part? Ethereum or the cheap, fast XRP Ledger?
