}
}

Configuration examples

Configuration for the CLI works like this:

In the current working directory for local runs

  1. Your configurations are in a local YAML configuration file .aptos/config.yaml, i.e., located in the current working directory where you run the CLI. In this case you must run your CLI commands from this current working directory for this configuration to be used.

  2. You can verify that the CLI is set to use this local configuration YAML file by running the command:

    aptos config show-global-config

    You should see the below output:

    {
    "Result": {
    "config_type": "Workspace"
    }
    }

    The Workspace value for the config_type indicates that the .aptos/config.yaml file is used for the CLI configuration.

In the home directory for the global runs

  1. Your configurations are in a global YAML configuration file ~/.aptos/global_config.yaml, i.e., located in your home directory.
  2. Set the CLI to use this global configuration YAML file by running this command:
    aptos config set-global-config --config-type global
    You will see the below output:
    {
    "Result": {
    "config_type": "Global"
    }
    }
    You can also show the global configuration with the show-global-config command.
    $ aptos config show-global-config
    {
    "Result": {
    "config_type": "Global"
    }
    }
Default configuration

If you did not set any global configuration, then the ./.aptos/config.yaml in the current working directory is used for configuration.

Setting up shell completion

You can set up shell completions with the generate-shell-completions command. You can lookup configuration for your specific shell. The supported shells are [bash, zsh, fish, powershell, elvish]. An example is below for oh my zsh.

aptos config generate-shell-completions --shell zsh --output-file ~/.oh-my-zsh/completions/_aptos

Initialize local configuration and create an account

A local folder named .aptos/ will be created with a configuration config.yaml which can be used to store configuration between CLI runs. This is local to your run, so you will need to continue running CLI from this folder, or reinitialize in another folder.

Step 1: Run Aptos init

The aptos init command will initialize the configuration with the private key you provided.

$ aptos init
Configuring for profile default

Aptos is now set up for account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696! Run `aptos help` for more information about commands

{
"Result": "Success"
}

Step 2: Changing the configuration

To change the configuration, you can either run the command aptos init or you can manually edit the .aptos/config.yaml that is in your current working directory.

Creating other profiles

You can also create other profiles for different endpoints and different keys. These can be made by adding the --profile argument, and can be used in most other commands to replace command line arguments.

$ aptos init --profile superuser

Aptos is now set up for account 18B61497FD290B02BB0751F44381CADA1657C2B3AA6194A00D9BC9A85FAD3B04! Run `aptos help` for more information about commands
{
"Result": "Success"
}

Account examples

Fund an account with the faucet

You can fund an account with the faucet via the CLI by using either an account address or with default (which defaults to the account address created with aptos init).

For example, to fund the account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696 that was created above with the aptos init command:

$ aptos account fund-with-faucet --account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696
{
"Result": "Added 10000 coins to account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696"
}
$ aptos account fund-with-faucet --account default
{
"Result": "Added 10000 coins to account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696"
}

View an account's balance and transfer events

You can view the balance and transfer events (deposits and withdrawals) either by explicity specying the accound address, as below:

$ aptos account list --query balance --account 00f1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696

or by specifying the default as below:

$ aptos account list --query balance --account default

Both the above commands will generate the following information on your terminal:

{
"Result": [
{
"coin": {
"value": "110000"
},
"deposit_events": {
"counter": "3",
"guid": {
"id": {
"addr": "0xf1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696",
"creation_num": "2"
}
}
},
"frozen": false,
"withdraw_events": {
"counter": "0",
"guid": {
"id": {
"addr": "0xf1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696",
"creation_num": "3"
}
}
}
}
]
}

Listing resources in an account

You can list the resources in an account from the command line. For example, see below for how to list the resources in the account you just created above:

$ aptos account list --query resources --account default

or

$ aptos account list --query resources --account 0xf1f20ddd0b0dd2291b6e42c97274668c479bca70f07c6b6a80b99720779696

Both the above commands will generate the following resource list information on your terminal:

{
"Result": [
{
"0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>": {
"coin": {
"value": "110000"
},
"deposit_events": {

"sequence_number": "0"
}
]
}

Listing modules in an account

You can pass different types of queries to view different items under an account. Currently, 'resources' and 'modules' are supported but more query types are coming. For example, to fetch modules:

$ aptos account list --query modules
{
"Result": [
{
"bytecode": "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",

Transferring coins

The Aptos CLI is a simple wallet as well, and can transfer coins between accounts.

$ aptos account transfer --account superuser --amount 100
{
"Result": {
"gas_used": 73,
"balance_changes": {
"742854f7dca56ea6309b51e8cebb830b12623f9c9d76c72c3242e4cad353dedc": {

Key examples

Generating a key

To allow generating private keys, you can use the aptos key generate command. You can generate either x25519 or ed25519 keys.

$ aptos key generate --key-type ed25519 --output-file output.key
{
"Result": {
"PrivateKey Path": "output.key",
"PublicKey Path": "output.key.pub"
}
}

Generating a peer config

To allow others to connect to your node, you need to generate a peer configuration. Below command shows how you can use the aptos CLI to generate a peer configuration and write it into a file named peer_config.yaml.

$ aptos key extract-peer --output-file peer_config.yaml

The above command will generate the following output on the terminal:

{
"Result": {
"8cfb85603080b13013b57e2e80887c695cfecd7ad8217d1cac22fa6f3b0b5752": {
"addresses": [],
"keys": [
"0x8cfb85603080b13013b57e2e80887c695cfecd7ad8217d1cac22fa6f3b0b5752"
],
"role": "Upstream"
}
}
}

The peer_config.yaml file will be created in your current working directory, with the contents as shown in the below example:

---
8cfb85603080b13013b57e2e80887c695cfecd7ad8217d1cac22fa6f3b0b5752:

Move examples

Compiling Move

The aptos CLI can be used to compile a Move package locally. The below example uses the HelloBlockchain in move-examples.

The named addresses can be either an account address, or a profile name.

$ aptos move compile --package-dir aptos-move/move-examples/hello_blockchain/ --named-addresses hello_blockchain=superuser

The above command will generate the below terminal output:

{
"Result": [
"742854F7DCA56EA6309B51E8CEBB830B12623F9C9D76C72C3242E4CAD353DEDC::Message"
]
}

Compiling and unit testing Move

The aptos CLI can also be used to compile and run unit tests locally. In this example, we'll use the HelloBlockchain in move-examples.

$ aptos move test --package-dir aptos-move/move-examples/hello_blockchain/ --named-addresses hello_blockchain=superuser

The above command will generate the following terminal output:

INCLUDING DEPENDENCY AptosFramework
INCLUDING DEPENDENCY AptosStdlib
INCLUDING DEPENDENCY MoveStdlib
BUILDING Examples

Test result: OK. Total tests: 2; passed: 2; failed: 0
{
"Result": "Success"
}

Proving Move

The aptos CLI can be used to run Move Prover which is a formal verification tool for the Move language. The below example proves the hello_prover package in move-examples.

aptos move prove --package-dir aptos-move/move-examples/hello_prover/

The above command will generate the following terminal output:

SUCCESS proving 1 modules from package `hello_prover` in 1.649s
{
"Result": "Success"
}

Move Prover may fail with the following terminal output if the dependencies are not installed and set up properly:

FAILURE proving 1 modules from package `hello_prover` in 0.067s
{
"Error": "Move Prover failed: No boogie executable set. Please set BOOGIE_EXE"
}

In this case, see Install the dependencies of Move Prover.

Debug and print stack trace

In this example, we will use DebugDemo in debug-move-example.

First, you need to include Move nursery in your Move toml file.

Now, you can use Debug::print and Debug::print_stack_trace in your DebugDemo Move file.

You can run the following command:

$ aptos move test --package-dir crates/aptos/debug-move-example

The command will generate the following output:

Running Move unit tests

Publishing a Move package with a named address

In this example, we'll use the HelloBlockchain in move-examples.

Publish the package with your account address set for HelloBlockchain.

Here, you need to change 8946741e5c907c43c9e042b3739993f32904723f8e2d1491564d38959b59ac71 to your account address.

$ aptos move publish --package-dir aptos-move/move-examples/hello_blockchain/ --named-addresses HelloBlockchain=8946741e5c907c43c9e042b3739993f32904723f8e2d1491564d38959b59ac71

You can additionally use named profiles for the addresses. The first placeholder is default

$ aptos move publish --package-dir aptos-move/move-examples/hello_blockchain/ --named-addresses HelloBlockchain=default
tip

When publishing Move modules, if multiple modules are in one package, then all the modules in this package must have the same account. If they have different accounts, then the publishing will fail at the transaction level.

Running a Move function

Now that you've published the function above, you can run it.

Arguments must be given a type with a colon to separate it. In this example, we want the input to be parsed as a string, so we put string:Hello!.

$ aptos move run --function-id 0xb9bd2cfa58ca29bce1d7add25fce5c62220604cd0236fe3f90d9de91ed9fb8cb::message::set_message --args string:hello!

Node command examples

Running a local testnet

You can run a local testnet from the aptos CLI, that will match the version it was built with. Additionally, it can run a faucet side by side with the local single node testnet.

$ aptos node run-local-testnet --with-faucet
Completed generating configuration:
Log file: "/Users/greg/.aptos/testnet/validator.log"
Test dir: "/Users/greg/.aptos/testnet"
Aptos root key path: "/Users/greg/.aptos/testnet/mint.key"
Waypoint: 0:d302c6b10e0fa68bfec9cdb383f24ef1189d8850d50b832365eea21ae52d8101
ChainId: TESTING
REST API endpoint: 0.0.0.0:8080
Fullnode network: /ip4/0.0.0.0/tcp/6181

Aptos is running, press ctrl-c to exit

This will have consistent state if the node is shutdown, it will start with the previous state. If you want to restart the chain from genesis, you can add the --force-restart flag.

$ aptos node run-local-testnet --with-faucet --force-restart

Genesis ceremonies

The aptos tool supports bootstrapping new blockchains through what is known as a genesis ceremony. The output of the genesis ceremony is the output of move instructions that prepares a blockchain for online operation. The input consists of:

  • A set of validators and their configuration
  • The initial set of Move modules, known as a framework
  • A unique ChainId (u8) that distinguishes this from other deployments
  • For test chains, there also exists an account that manages the minting of AptosCoin

Generating genesis

  • The genesis organizer constructs a Layout and distributes it.
  • The genesis organizer prepares the Aptos framework's bytecode and distributes it.
  • Each participant generates their ValidatorConfiguration and distributes it.
  • Each participant generates a genesis.blob from the resulting contributions
  • The genesis organizer executes the genesis.blob to derive the initial waypoint and distributes it.
  • Each participant begins their aptos-node. The aptos-node verifies upon startup that the genesis.blob with the waypoint provided by the genesis organizer .
  • The blockchain will begin consensus after a quorum of stake is available.

Prepare aptos-core

The following guide assumes that you have access to the Aptos-core repository or the associated tools. You can download and prepare Aptos-core from GitHub:

git clone https://github.com/aptos-labs/aptos-core.git
cd aptos-core
git checkout --track origin/testnet
./scripts/dev_setup.sh
source ~/.cargo/env

The layout file

The layout file contains:

  • root_key: an Ed25519 public key for AptosCoin management.
  • users: the set of participants
  • chain_id: the ChainId or a unique integer that distinguishes this deployment from other Aptos networks

An example:

root_key: "0xca3579457555c80fc7bb39964eb298c414fd60f81a2f8eedb0244ec07a26e575"
users:
- alice
- bob
chain_id: 8

Building the Aptos Framework

From your Aptos-core repository, build the framework and package it:

cargo run --package framework
mkdir aptos-framework-release
cp aptos-framework/releases/artifacts/current/build/**/bytecode_modules/* aptos-framework-release

The framework will be stored within the aptos-framework-release directory.

The ValidatorConfiguration file

The ValidatorConfiguration file contains:

  • account_address: The account that manages this validator. This must be derived from the account_key provided within te ValidatorConfiguration file.
  • consensus_key: The public key for authenticating consensus messages from the validator
  • account_key: The public key for the account that manages this validator. This is used to derive the account_address.
  • network_key: The public key for both validator and fullnode network authentication and encryption.
  • validator_host: The network address where the validator resides. This contains a host and port field. The host should either be a DNS name or an IP address. Currently only IPv4 is supported.
  • full_node_host: An optional network address where the fullnode resides. This contains a host and port field. The host should either be a DNS name or an IP address. Currently only IPv4 is supported.
  • stake_amount: The number of coins being staked by this node. This is expected to be 1, if it is different the configuration will be considered invalid.

An example:

account_address: ccd49f3ea764365ac21e99f029ca63a9b0fbfab1c8d8d5482900e4fa32c5448a
consensus_key: "0xa05b8f41057ac72f9ca99f5e3b1b787930f03ba5e448661f2a1fac98371775ee"
account_key: "0x3d15ab64c8b14c9aab95287fd0eb894aad0b4bd929a5581bcc8225b5688f053b"
network_key: "0x43ce1a4ac031b98bb1ee4a5cd72a4cca0fd72933d64b22cef4f1a61895c2e544"
validator_host:
host: bobs_host
port: 6180
full_node_host:
host: bobs_host
port: 6182
stake_amount: 1

To generate this using the aptos CLI:

  1. Generate your validator's keys:
cargo run --package aptos -- genesis generate-keys --output-dir bobs
  1. Generate your ValidatorConfiguration:
cargo run --package aptos -- \\
genesis set-validator-configuration \\
--keys-dir bobs \\
--username bob \\
--validator-host bobs_host:6180 \\
--full-node-host bobs_host:6180 \\
--local-repository-dir .
  1. The last command will produce a bob.yaml file that should be distributed to other participants for genesis.blob generation.

Generating a genesis and waypoint

genesis.blob and the waypoint can be generated after obtaining the Layout file, each of the individual ValidatorConfiguration files, and the framework release. It is important to validate that the ValidatorConfiguration provided in the earlier stage is the same as in the distribution for generating the genesis.blob. If there is a mismatch, inform all participants.

To generate the genesis.blob and waypoint:

  • Place the Layout file in a directory, e.g., genesis.
  • Place all the ValidatorConfiguration files into the genesis directory.
  • Ensure that the ValidatorConfiguration files are listed under the set of users within the Layout file.
  • Make a framework directory within the genesiss directory and place the framework release .mv files into the framework directory.
  • Use the aptos CLI to generate genesis and waypoint:
cargo run --package aptos -- genesis generate-genesis --local-repository-dir genesis

Starting an aptos-node

Upon generating the genesis.blob and waypoint, place them into your validator and fullnode's configuration directory and begin your validator and fullnode.
