Base

You're building an app and can use:

1. Privy, et al that enable a simple, segregated wallet for your app alone

2. Single sign-on w/ unified wallet that enables users to bring their assets/identity everywhere

Assume for a moment they both offer seamless UX w/o janky app-switching, gas fees, etc.

Which do you choose?

3. Particle Network and ERC-4337 Accounts

Create your own validator or module to perform functions on your contracts. All they have to do is enable it the first time. Then you can do whatever you desire on the backend, sponsor their gas, submit batch transactions, etc.

Can also do custodial 4337 accounts w/ pks
