quick demo of what i've been working on @base with the smart wallet team over the past few weeks: *automatic* sub accounts get rid of wallet confirmation popups in your app without having to worry about funding flows with 4 lines of code available on base sepolia in our sdk for now. docs in replies

This is ABSOLUTELY AMAZING! Such great work. Love sub-accounts. Super convenient. Do sub-accounts also solve security issues associated with potentially suspicious connections, because even if your sub-account gets rugged it's ring-fenced to the max draw down from your global account?

yep that's the idea. a malicious app only has access to as much as the spend limit permits. in the demo it's like $5/day and you can later go and revoke spend permissions at https://keys-dev.coinbase.com/settings/permissions if you no longer trust the app by the time this launches on mainnet you'll be able to see all the apps you have sub accounts with and you'll be able to pull the funds back into your global account all in one place

that is so great. i can see this massively increasing usage of newly discovered apps and pages. currently people are hesitant to simply connect to any app they haven’t heard of or seen on social, because you never know. also seems like a great way to do your own personal escrow / proof of funds. they can look to see that you’ve funded the sub-account associated with the transaction. wonder if you could set up so that the creditor has a control relationship and a security interest in the sub-account. if so could be a composable part of peer-to-peer secured lending. wondering if you could adapt something like this to solve the problem of on chain services contracts and payments.
