Ignite CLI offers everything you need to scaffold, test, build, and launch your blockchain
Synopsis
Ignite CLI is a tool for creating sovereign blockchains built with Cosmos SDK, the world’s most popular modular blockchain framework. Ignite CLI offers everything you need to scaffold, test, build, and launch your blockchain.
To get started, create a blockchain:
ignite scaffold chain github.com/username/mars

ignite account
Commands for managing Ignite accounts
Synopsis
Commands for managing Ignite accounts. An Ignite account is a private/public keypair stored in a keyring. Currently Ignite accounts are used when interacting with Ignite relayer commands.
Note: Ignite account commands are not for managing your chain's keys and accounts. Use you chain's binary to manage accounts from "config.yml". For example, if your blockchain is called "mychain", use "mychaind keys" to manage keys for the chain.

ignite chain
Build, initialize and start a blockchain node or perform other actions on the blockchain
Synopsis
Commands in this namespace let you to build, initialize, and start your blockchain node locally for development purposes.
To run these commands you should be inside the project's directory so that Ignite can find the source code. To ensure that you are, run "ls", you should see the following files in the output: "go.mod", "x", "proto", "app", etc.
By default the "build" command will identify the "main" package of the project, install dependencies if necessary, set build flags, compile the project into a binary and install the binary. The "build" command is useful if you just want the compiled binary, for example, to initialize and start the chain manually. It can also be used to release your chain's binaries automatically as part of continuous integration workflow.
The "init" command will build the chain's binary and use it to initialize a local validator node. By default the validator node will be initialized in your $HOME directory in a hidden directory that matches the name of your project. This directory is called a data directory and contains a chain's genesis file and a validator key. This command is useful if you want to quickly build and initialize the data directory and use the chain's binary to manually start the blockchain. The "init" command is meant only for development purposes, not production.
The "serve" command builds, initializes, and starts your blockchain locally with a single validator node for development purposes. "serve" also watches the source code directory for file changes and intelligently re-builds/initializes/starts the chain, essentially providing "code-reloading". The "serve" command is meant only for development purposes, not production.
To distinguish between production and development consider the following.
In production, blockchains often run the same software on many validator nodes that are run by different people and entities. To launch a blockchain in production, the validator entities coordinate the launch process to start their nodes simultaneously.
During development, a blockchain can be started locally on a single validator node. This convenient process lets you restart a chain quickly and iterate faster. Starting a chain on a single node in development is similar to starting a traditional web application on a local server.
The "faucet" command lets you send tokens to an address from the "faucet" account defined in "config.yml". Alternatively, you can use the chain's binary to send token from any other account that exists on chain.
The "simulate" command helps you start a simulation testing process for your chain.

ignite chain build
Build a node binary
Synopsis
The build command compiles the source code of the project into a binary and installs the binary in the $(go env GOPATH)/bin directory.
You can customize the output directory for the binary using a flag:
ignite chain build --output dist
To compile the binary Ignite first compiles protocol buffer (proto) files into Go source code. Proto files contain required type and services definitions. If you're using another program to compile proto files, you can use a flag to tell Ignite to skip the proto compilation step:
ignite chain build --skip-proto
Afterwards, Ignite install dependencies specified in the go.mod file. By default Ignite doesn't check that dependencies of the main module stored in the module cache have not been modified since they were downloaded. To enforce dependency checking (essentially, running "go mod verify") use a flag:
ignite chain build --check-dependencies
Next, Ignite identifies the "main" package of the project. By default the "main" package is located in "cmd/{app}d" directory, where "{app}" is the name of the scaffolded project and "d" stands for daemon. If your your project contains more than one "main" package, specify the path to the one that Ignite should compile in config.yml:
build: main: custom/path/to/main
By default the binary name will match the top-level module name (specified in go.mod) with a suffix "d". This can be customized in config.yml:
build: binary: mychaind
You can also specify custom linker flags:
build: ldflags: - "-X main.Version=development" - "-X main.Date=01/05/2022T19:54"
To build binaries for a release, use the --release flag. The binaries for one or more specified release targets are built in a "release/" directory in the project's source directory. Specify the release targets with GOOS:GOARCH build tags. If the optional --release.targets is not specified, a binary is created for your current environment.
ignite chain build --release -t linux:amd64 -t darwin:amd64 -t darwin:arm64

ignite chain init
Initialize your chain
Synopsis
The init command compiles and installs the binary (like "ignite chain build") and uses that binary to initialize the blockchain's data directory for one validator. To learn how the build process works, refer to "ignite chain build --help".
By default, the data directory will be initialized in $HOME/.mychain, where "mychain" is the name of the project. To set a custom data directory use the --home flag or set the value in config.yml:
init: home: "~/.customdir"
The data directory contains three files in the "config" directory: app.toml, config.toml, client.toml. These files let you customize the behavior of your blockchain node and the client executable. When a chain is re-initialized the data directory can be reset. To make some values in these files persistent, set them in config.yml:
init: app: minimum-gas-prices: "0.025stake" config: consensus: timeout_commit: "5s" timeout_propose: "5s" client: output: "json"
The configuration above changes the minimum gas price of the validator (by default the gas price is set to 0 to allow "free" transactions), sets the block time to 5s, and changes the output format to JSON. To see what kind of values this configuration accepts see the generated TOML files in the data directory.
As part of the initialization process Ignite creates on-chain accounts with token balances. By default, config.yml has two accounts in the top-level "accounts" property. You can add more accounts and change their token balances. Refer to config.yml guide to see which values you can set.
One of these accounts is a validator account and the amount of self-delegated tokens can be set in the top-level "validator" property.
One of the most important components of an initialized chain is the genesis file, the 0th block of the chain. The genesis file is stored in the data directory "config" subdirectory and contains the initial state of the chain, including consensus and module parameters. You can customize the values of the genesis in config.yml:
genesis: app_state: staking: params: bond_denom: "foo"
The example above changes the staking token to "foo". If you change the staking denom, make sure the validator account has the right tokens.
The init command is meant to be used ONLY FOR DEVELOPMENT PURPOSES. Under the hood it runs commands like "appd init", "appd add-genesis-account", "appd gentx", and "appd collect-gentx". For production, you may want to run these commands manually to ensure a production-level node initialization.

ignite chain serve
Start a blockchain node in development
Synopsis
The serve command compiles and installs the binary (like "ignite chain build"), uses that binary to initialize the blockchain's data directory for one validator (like "ignite chain init"), and starts the node locally for development purposes with automatic code reloading.
Automatic code reloading means Ignite starts watching the project directory. Whenever a file change is detected, Ignite automatically rebuilds, reinitializes and restarts the node.
Whenever possible Ignite will try to keep the current state of the chain by exporting and importing the genesis file.
To force Ignite to start from a clean slate even if a genesis file exists, use the following flag:
ignite chain serve --reset-once
To force Ignite to reset the state every time the source code is modified, use the following flag:
ignite chain serve --force-reset
With Ignite it's possible to start more than one blockchain from the same source code using different config files. This is handy if you're building inter-blockchain functionality and, for example, want to try sending packets from one blockchain to another. To start a node using a specific config file:
ignite chain serve --config mars.yml
The serve command is meant to be used ONLY FOR DEVELOPMENT PURPOSES. Under the hood, it runs "appd start", where "appd" is the name of your chain's binary. For production, you may want to run "appd start" manually.

ignite network
Launch a blockchain in production
Synopsis
Ignite Network commands allow to coordinate the launch of sovereign Cosmos blockchains.
To launch a Cosmos blockchain you need someone to be a coordinator and others to be validators. These are just roles, anyone can be a coordinator or a validator. A coordinator publishes information about a chain to be launched on the Ignite blockchain, approves validator requests and coordinates the launch. Validators send requests to join a chain and start their nodes when a blockchain is ready for launch.
To publish the information about your chain as a coordinator run the following command (the URL should point to a repository with a Cosmos SDK chain):
ignite network chain publish github.com/ignite/example
This command will return a launch identifier you will be using in the following commands. Let's say this identifier is 42.
Next, ask validators to initialize their nodes and request to join the network as validators. For a testnet you can use the default values suggested by the CLI.
ignite network chain init 42
ignite network chain join 42 --amount 95000000stake
As a coordinator list all validator requests:
ignite network request list 42
Approve validator requests:
ignite network request approve 42 1,2
Once you've approved all validators you need in the validator set, announce that the chain is ready for launch:
ignite network chain launch 42
Validators can now prepare their nodes for launch:
ignite network chain prepare 42
The output of this command will show a command that a validator would use to launch their node, for example “exampled --home ~/.example”. After enough validators launch their nodes, a blockchain will be live.

ignite scaffold
Scaffold a new blockchain, module, message, query, and more
Synopsis
Scaffolding is a quick way to generate code for major pieces of your application.
For details on each scaffolding target (chain, module, message, etc.) run the corresponding command with a "--help" flag, for example, "ignite scaffold chain --help".
The Ignite team strongly recommends committing the code to a version control system before running scaffolding commands. This will make it easier to see the changes to the source code as well as undo the command if you've decided to roll back the changes.
This blockchain you create with the chain scaffolding command uses the modular Cosmos SDK framework and imports many standard modules for functionality like proof of stake, token transfer, inter-blockchain connectivity, governance, and more. Custom functionality is implemented in modules located by convention in the "x/" directory. By default, your blockchain comes with an empty custom module. Use the module scaffolding command to create an additional module.
An empty custom module doesn't do much, it's basically a container for logic that is responsible for processing transactions and changing the application state. Cosmos SDK blockchains work by processing user-submitted signed transactions, which contain one or more messages. A message contains data that describes a state transition. A module can be responsible for handling any number of messages.
A message scaffolding command will generate the code for handling a new type of Cosmos SDK message. Message fields describe the state transition that the message is intended to produce if processed without errors.
Scaffolding messages is useful to create individual "actions" that your module can perform. Sometimes, however, you want your blockchain to have the functionality to create, read, update and delete (CRUD) instances of a particular type. Depending on how you want to store the data there are three commands that scaffold CRUD functionality for a type: list, map, and single. These commands create four messages (one for each CRUD action), and the logic to add, delete, and fetch the data from the store. If you want to scaffold only the logic, for example, you've decided to scaffold messages separately, you can do that as well with the "--no-message" flag.
Reading data from a blockchain happens with a help of queries. Similar to how you can scaffold messages to write data, you can scaffold queries to read the data back from your blockchain application.
You can also scaffold a type, which just produces a new protocol buffer file with a proto message description. Note that proto messages produce (and correspond with) Go types whereas Cosmos SDK messages correspond to proto "rpc" in the "Msg" service.
If you're building an application with custom IBC logic, you might need to scaffold IBC packets. An IBC packet represents the data sent from one blockchain to another. You can only scaffold IBC packets in IBC-enabled modules scaffolded with an "--ibc" flag. Note that the default module is not IBC-enabled.

ignite scaffold chain
Fully-featured Cosmos SDK blockchain
Synopsis
Create a new application-specific Cosmos SDK blockchain.
For example, the following command will create a blockchain called "hello" in the "hello/" directory:
ignite scaffold chain hello
A project name can be a simple name or a URL. The name will be used as the Go module path for the project. Examples of project names:
ignite scaffold chain foo ignite scaffold chain foo/bar ignite scaffold chain example.org/foo ignite scaffold chain github.com/username/foo
A new directory with source code files will be created in the current directory. To use a different path use the "--path" flag.
Most of the logic of your blockchain is written in custom modules. Each module effectively encapsulates an independent piece of functionality. Following the Cosmos SDK convention, custom modules are stored inside the "x/" directory. By default, Ignite creates a module with a name that matches the name of the project. To create a blockchain without a default module use the "--no-module" flag. Additional modules can be added after a project is created with "ignite scaffold module" command.
Account addresses on Cosmos SDK-based blockchains have string prefixes. For example, the Cosmos Hub blockchain uses the default "cosmos" prefix, so that addresses look like this: "cosmos12fjzdtqfrrve7zyg9sv8j25azw2ua6tvu07ypf". To use a custom address prefix use the "--address-prefix" flag. For example:
ignite scaffold chain foo --address-prefix bar
By default when compiling a blockchain's source code Ignite creates a cache to speed up the build process. To clear the cache when building a blockchain use the "--clear-cache" flag. It is very unlikely you will ever need to use this flag.
The blockchain is using the Cosmos SDK modular blockchain framework. Learn more about Cosmos SDK on https://docs.cosmos.network

ignite scaffold list
CRUD for data stored as an array
Synopsis
The "list" scaffolding command is used to generate files that implement the logic for storing and interacting with data stored as a list in the blockchain state.
The command accepts a NAME argument that will be used as the name of a new type of data. It also accepts a list of FIELDs that describe the type.
The interaction with the data follows the create, read, updated, and delete (CRUD) pattern. For each type three Cosmos SDK messages are defined for writing data to the blockchain: MsgCreate{Name}, MsgUpdate{Name}, MsgDelete{Name}. For reading data two queries are defined: {Name} and {Name}All. The type, messages, and queries are defined in the "proto/" directory as protocol buffer messages. Messages and queries are mounted in the "Msg" and "Query" services respectively.
When messages are handled, the appropriate keeper methods are called. By convention, the methods are defined in "x/{moduleName}/keeper/msg_server_{name}.go". Helpful methods for getting, setting, removing, and appending are defined in the same "keeper" package in "{name}.go".
The "list" command essentially allows you to define a new type of data and provides the logic to create, read, update, and delete instances of the type. For example, let's review a command that generates the code to handle a list of posts and each post has "title" and "body" fields:
ignite scaffold list post title body
This provides you with a "Post" type, MsgCreatePost, MsgUpdatePost, MsgDeletePost and two queries: Post and PostAll. The compiled CLI, let's say the binary is "blogd" and the module is "blog", has commands to query the chain (see "blogd q blog") and broadcast transactions with the messages above (see "blogd tx blog").
The code generated with the list command is meant to be edited and tailored to your application needs. Consider the code to be a "skeleton" for the actual business logic you will implement next.
By default, all fields are assumed to be strings. If you want a field of a different type, you can specify it after a colon ":". The following types are supported: string, bool, int, uint, coin, array.string, array.int, array.uint, array.coin. An example of using custom types:
ignite scaffold list pool amount:coin tags:array.string height:int
Ignite also supports custom types:
ignite scaffold list product-details name description
ignite scaffold list product price:coin details:ProductDetails
In the example above the "ProductDetails" type was defined first, and then used as a custom type for the "details" field. Ignite doesn't support arrays of custom types yet.
By default the code will be scaffolded in the module that matches your project's name. If you have several modules in your project, you might want to specify a different module:
ignite scaffold list post title body --module blog
By default, each message comes with a "creator" field that represents the address of the transaction signer. You can customize the name of this field with a flag:
ignite scaffold list post title body --signer author
It's possible to scaffold just the getter/setter logic without the CRUD messages. This is useful when you want the methods to handle a type, but would like to scaffold messages manually. Use a flag to skip message scaffolding:
ignite scaffold list post title body --no-message
The "creator" field is not generated if a list is scaffolded with the "--no-message" flag.

ignite scaffold map
CRUD for data stored as key-value pairs
Synopsis
The "map" scaffolding command is used to generate files that implement the logic for storing and interacting with data stored as key-value pairs (or a dictionary) in the blockchain state.
The "map" command is very similar to "ignite scaffold list" with the main difference in how values are indexed. With "list" values are indexed by an incrementing integer, whereas "list" values are indexed by a user-provided value (or multiple values).
Let's use the same blog post example:
ignite scaffold map post title body
This command scaffolds a "Post" type and CRUD functionality to create, read, updated, and delete posts. However, when creating a new post with your chain's binary (or by submitting a transaction through the chain's API) you will be required to provide an "index":
blogd tx blog create-post [index] [title] [body] blogd tx blog create-post hello "My first post" "This is the body"
This command will create a post and store it in the blockchain's state under the "hello" index. You will be able to fetch back the value of the post by querying for the "hello" key.
blogd q blog show-post hello
To customize the index, use the "--index" flag. Multiple indices can be provided, which simplifies querying values. For example:
ignite scaffold map product price desc --index category,guid
With this command, you would get a "Product" value indexed by both a category and a GUID (globally unique ID). This will let you programmatically fetch product values that have the same category but are using different GUIDs.
Since the behavior of "list" and "map" scaffolding is very similar, you can use the "--no-message", "--module", "--signer" flags as well as the colon syntax for custom types.

ignite scaffold message
Message to perform state transition on the blockchain
Synopsis
Message scaffolding is useful for quickly adding functionality to your blockchain to handle specific Cosmos SDK messages.
Messages are objects whose end goal is to trigger state transitions on the blockchain. A message is a container for fields of data that affect how the blockchain's state will change. You can think of messages as "actions" that a user can perform.
For example, the bank module has a "Send" message for token transfers between accounts. The send message has three fields: from address (sender), to address (recipient), and a token amount. When this message is successfully processed, the token amount will be deducted from the sender's account and added to the recipient's account.
Ignite's message scaffolding lets you create new types of messages and add them to your chain. For example:
ignite scaffold message add-pool amount:coins denom active:bool --module dex
The command above will create a new message MsgAddPool with three fields: amount (in tokens), denom (a string), and active (a boolean). The message will be added to the "dex" module.
By default, the message is defined as a proto message in the "proto/{app}/{module}/tx.proto" and registered in the "Msg" service. A CLI command to create and broadcast a transaction with MsgAddPool is created in the module's "cli" package. Additionally, Ignite scaffolds a message constructor and the code to satisfy the sdk.Msg interface and register the message in the module.
Most importantly in the "keeper" package Ignite scaffolds an "AddPool" function. Inside this function, you can implement message handling logic.
When successfully processed a message can return data. Use the —response flag to specify response fields and their types. For example
ignite scaffold message create-post title body --response id:int,title
The command above will scaffold MsgCreatePost which returns both an ID (an integer) and a title (a string).
Message scaffolding follows the rules as "ignite scaffold list/map/single" and supports fields with standard and custom types. See "ignite scaffold list —help" for details.

ignite scaffold module
Scaffold a Cosmos SDK module
Synopsis
Scaffold a new Cosmos SDK module.
Cosmos SDK is a modular framework and each independent piece of functionality is implemented in a separate module. By default your blockchain imports a set of standard Cosmos SDK modules. To implement custom functionality of your blockchain, scaffold a module and implement the logic of your application.
This command does the following:
Creates a directory with module's protocol buffer files in "proto/"
Creates a directory with module's boilerplate Go code in "x/"
Imports the newly created module by modifying "app/app.go"
Creates a file in "testutil/keeper/" that contains logic to create a keeper for testing purposes
This command will proceed with module scaffolding even if "app/app.go" doesn't have the required default placeholders. If the placeholders are missing, you will need to modify "app/app.go" manually to import the module. If you want the command to fail if it can't import the module, use the "--require-registration" flag.
To scaffold an IBC-enabled module use the "--ibc" flag. An IBC-enabled module is like a regular module with the addition of IBC-specific logic and placeholders to scaffold IBC packets with "ignite scaffold packet".
A module can depend on one or more other modules and import their keeper methods. To scaffold a module with a dependency use the "--dep" flag
For example, your new custom module "foo" might have functionality that requires sending tokens between accounts. The method for sending tokens is a defined in the "bank"'s module keeper. You can scaffold a "foo" module with the dependency on "bank" with the following command:
ignite scaffold module foo --dep bank
You can then define which methods you want to import from the "bank" keeper in "expected_keepers.go".
You can also scaffold a module with a list of dependencies that can include both standard and custom modules (provided they exist):
ignite scaffold module bar --dep foo,mint,account
Note: the "--dep" flag doesn't install third-party modules into your application, it just generates extra code that specifies which existing modules your new custom module depends on.
A Cosmos SDK module can have parameters (or "params"). Params are values that can be set at the genesis of the blockchain and can be modified while the blockchain is running. An example of a param is "Inflation rate change" of the "mint" module. A module can be scaffolded with params using the "--params" flag that accepts a list of param names. By default params are of type "string", but you can specify a type for each param. For example:
ignite scaffold module foo --params baz:uint,bar:bool
Refer to Cosmos SDK documentation to learn more about modules, dependencies and params.
