| # CIP-45 flow | ||
|
|
||
| This example is a Work In Progress. It shows how to use the `@marlowe.io/wallet/peer-connect` module together with the [https://github.com/fabianbormann/cardano-peer-connect](cardano-peer-connect) library. | ||
|
|
||
| ## How to run | ||
|
|
||
| 1. Build the project | ||
| ```bash | ||
| $ npm i | ||
| $ npm run build | ||
| ``` | ||
| 2. Serve the examples folder | ||
| ```bash | ||
| $ npm run serve-dev | ||
| ``` | ||
| 3. Open the browser at http://localhost:1337/examples/cip45-flow/ | ||
| 4. Use a cip45 wallet like eternl and scan the QR code to connect to the wallet | ||
| 5. After the prompt to connect, you can click the create contract button. |
