This is an example of how to use the MetaMask provider within the 0xcert Framework v2.

The example is put in the context of a simple dApp to showcase not only functionalities but also the basic principles of handling blockchain communication through the 0xcert Framework. The main logic is isolated in the src/example.ts file while response handling is located in index.ts. The basic configuration needed for communication can be found in the src/config.ts file.

To keep the example as simple as possible, some values are hardcoded, such as order definition. You can change those in the src/config.ts file.

The src/config.ts file also contains some empty variables that you need to set for the example to work. Mainly, the valueLedgerId, which you got at deploying a new value ledger in the value management guide, and the MetaMask account (account1Id) that deployed the value ledger.
