How to create a Flow account from the command line

The Flow CLI provides a command to submit an account creation transaction to any Flow Access API.

⚠️ This command requires an existing Testnet or Mainnet account.

Example Usage

# Create an account on Flow Testnet
> flow accounts create \
    --key a69c6986e846ba6d0....1397f5904cd319c3e01e96375d5777f1a47010 \
    --signer my-testnet-account 

Address	 0x01cf0e2f2f715450
Balance	 10000000
Keys	 1

Key 0	Public Key		 a69c6986e846ba6d0....1397f5904cd319c3e01e96375d5777f1a47010
	Weight			 1000
	Signature Algorithm	 ECDSA_P256
	Hash Algorithm		 SHA3_256

In the above example, the flow.json file would look something like this:

  "accounts": {
    "my-testnet-account": {
      "address": "a2c4941b5f3c7151",
      "keys": "12c5dfde...bb2e542f1af710bd1d40b2"


Public Key

  • Flag: --key
  • Valid inputs: a hex-encoded public key in raw form.

Specify the public key that will be added to the new account upon creation.

Key Weight

  • Flag: --key-weight
  • Valid inputs: number between 0 and 1000
  • Default: 1000

Specify the weight of the public key being added to the new account.

When opting to use this flag, you must specify a --key-weight flag for each public --key flag provided.

Public Key Signature Algorithm

  • Flag: --sig-algo
  • Valid inputs: "ECDSA_P256", "ECDSA_secp256k1"
  • Default: "ECDSA_P256"

Specify the ECDSA signature algorithm for the provided public key. This option can only be used together with the --key flag.

Flow supports the secp256k1 and P-256 curves.

Public Key Hash Algorithm

  • Flag: --hash-algo
  • Valid inputs: "SHA2_256", "SHA3_256"
  • Default: "SHA3_256"

Specify the hash algorithm that will be paired with the public key upon account creation.


  • Flag: --signer
  • Valid inputs: the name of an account defined in flow.json.

Specify the name of the account that will be used to sign the transaction and pay the account creation fee.


  • Flag: --contract
  • Valid inputs: String with format name:filename, where name is name of the contract as it is defined in the contract source code and filename is the filename of the contract source code.

Specify one or more contracts to be deployed during account creation.


  • Flag: --host
  • Valid inputs: an IP address or hostname.
  • Default: (Flow Emulator)

Specify the hostname of the Access API that will be used to execute the command. This flag overrides any host defined by the --network flag.


  • Flag: --network
  • Short Flag: -n
  • Valid inputs: the name of a network defined in the configuration (flow.json)
  • Default: emulator

Specify which network you want the command to use for execution.


  • Flag: --filter
  • Short Flag: -x
  • Valid inputs: a case-sensitive name of the result property.

Specify any property name from the result you want to return as the only value.


  • Flag: --output
  • Short Flag: -o
  • Valid inputs: json, inline

Specify the format of the command results.


  • Flag: --save
  • Short Flag: -s
  • Valid inputs: a path in the current filesystem.

Specify the filename where you want the result to be saved


  • Flag: --log
  • Short Flag: -l
  • Valid inputs: none, error, debug
  • Default: info

Specify the log level. Control how much output you want to see during command execution.


  • Flag: --config-path
  • Short Flag: -f
  • Valid inputs: a path in the current filesystem.
  • Default: flow.json

Specify the path to the flow.json configuration file. You can use the -f flag multiple times to merge several configuration files.
