What's the best product for this?

1. Neighbor kid does a chore for you.
2. You want to pay them in USDC. 
3. They only have an Apple Watch.

I’ve thought about this, probably not a massive market but some sort of piggy bank type wallet/app for parents/kids.

Wouldn’t work for this scenario but with own kids/family some sort of multisig where funds can be transferred at a certain date. Can get better APY then traditional savings account. 

This scenario is niche so very hard.

For sure. 

I can easily see a delightful product.

It’s harder to see a big business or venture scale outcome. 

Counter is that families make up for a large majority of consumer spend and this could be a wedge into some sort of network.
