Opening Ceremony

Watch the recording of the livestream [here](https://nsb.dev/base-batches-2025-workshop-1).

Workshop 1 - Building Social with MiniKit

Explore Smart Wallet's newest feature; Sub Accounts, which allows your users to create unique app-specific wallet addresses tied to their main account. We will show how you can use Sub Accounts with Spend Limits in order to create a consumer experience similar (or superior) to offchain apps with onchain capabilities built-in.
