Every Asset Layer app has a corresponding Handcash app. So if you don’t have a Handcash developer account, you are going to need one. Head to Handcash and create your account. Next you need to make Asset Layer an app extension for your test app, which allows users to authenticate for Handcash and Asset Layer simultaneously!
We recommend you create two Handcash apps for your Asset Layer app - one to use for developing locally, and another for deploying your app to production. From each app you will need both the HANDCASH_APP_ID & HANDCASH_APP_SECRET - which will be used for configuring your Environment Variables, discussed later.
Next configure the redirects for your Handcash apps. For local development, enter http://localhost:3000 for the redirects. For your production app, enter the url for your app. For example, the production redirect for the Sample App is https://nftsample.app .
The only setting you need to change to use Asset Layer is to add the Asset Layer extension to your Handcash apps. To do this, go to the Extensions menu and click the “+ Add extension” button. Paste in the Asset Layer app ID, 64cc28be6d72f643d8140436, press enter and you are good to go.
