A note

Maestro allows you to place orders for components, not products. That might be a little counter-intuitive, but since we're often dealing with 3D printed products with multiple parts, each part must be ordered separately to self assemble the product.

Give it a spin

Start by creating an entry for a new product. In this example, I'll enter milk as a product. Not all products need to have multiple components, but in the milk example, milk is a product that consists of one component. A more complex example is our 3D-printed bike, which consists of 32 separate parts or components.

Each supplier is identified by an address on the Ethereum network. In this case, the supplier address of Harry's Market is {ethereum address}. (and then fill in the blanks in the image with 67, some ethereum address, 8, delivery person from Harry's Market, 3893, 3980 Balboa Drive, Oakland, CA 98239.
