// # ✒️ Challenge 1: Basics of ink! and setting up a DAO contract
//
// - **Difficulty**: Easy
// - **Submission Criteria:** ink! contract must
//     - Have a constructor accepting a name parameter.
//     - Have a storage field for the DAO name.
//     - Implement the `BasicDao` trait methods.
//     - Unit test for constructor and setting DAO name.
//     - Be built and deployed on Pop Network testnet.
// - **Submission Guidelines:**
//     - Verify with R0GUE DevRel, and post on X.
// - **Prize:** sub0 merch
