## Launching in Production

For production, the steps are almost identical, but some changes are required:

1. Create a developer account on the [production console](https://www.crossmint.com/console)
2. Create a production client API key on the [API Keys](https://www.crossmint.com/console/projects/apiKeys) page with the API scopes `users.create`, `users.read`, `wallets.read`, `wallets.create`, `wallets:transactions.create`, `wallets:transactions.sign`, `wallets:balance.read`, `wallets.fund`
3. Replace your test API key with the production key
