+If you have your contract class in a Json file, you can use the abiwan CLI to generate the `abi.ts` typescript file

+You need to first get the **ABI** of the contract and export it in a typescript file, you can do so using one command combining both [`starkli`](https://github.com/xJonathanLEI/starkli) (tested with version 0.2.3) and `npx abi-wan-kanabi`:
