Second Hand Music

Welcome to Second Hand Music. You can sell or buy used music products on blockchain like microphones here.

NOTE FOR NCD LOOM VIDEO: there was a problem causing the createMidi function not to work properly. createMic was working so i didnt noticed at the first sight. In the loom video i didnt noticed that too. The problem was on the model.ts , i forgot to write @Nearbindgen to Midis class. I fixed it. I hope you can review this accordingly.

Note 2: Updated Contract, added few more instruments and products.
