Mainnet Account Setup Guidelines

To deploy your smart contracts to the mainnet, follow the steps below to register, fund, and set up a new account.

Note: This account will be used for production purposes. Ensure proper key management. Using a Key Management Service (KMS) is the best practice. By default, this command generates an ECDSA key pair on the P-256 curve. Keep in mind that the Flow CLI is intended for development purposes only and is not recommended for production use. Handling keys using a Key Management Service is the best practice.

Create an account

You can easily create a new funded account on the mainnet using the Flow CLI. Execute the following command flow accounts create and choose a name for the account and the network, which in this case is mainnet. After that, the account private key is saved into a separate file called {name}.pkey. We advise switching to a KMS system for production use; you can read more about it here.
