Platform & Toolchain

Local development environment

  • Getting Started: Install the InfraBlockchain-Antelope platform in your local development environment.


The InfraBlockchain-Antelope platform is made up of the following components and toolchain:

  1. infra-node: the core InfraBlockchain-Antelope node daemon that can be configured with plugins to run a node. Example uses are block production, dedicated API endpoints, and local development.

  2. infra-cli: the command line interface to interact with the blockchain and to manage wallets.

  3. infra-keychain: the component that securely stores InfraBlockchain-Antelope keys in wallets.

  4. infrablockchain.cdt: toolchain for WebAssembly (Wasm) and a set of tools to facilitate smart contract writing for the InfraBlockchain-Antelope platform.

The basic relationship between these components is illustrated in the following diagram:

InfraBlockchain-Antelope also provides a frontend library for javascript development called Infrablockchain-js.


Infra-node is the core InfraBlockchain-Antelope node daemon. Infra-node handles the blockchain data persistence layer, peer-to-peer networking, and contract code scheduling. For development environments, Infra-node enables you to set up a single node blockchain network. Infra-node offers a wide range of features through plugins which can be enabled or disabled at start time via the command line parameters or configuration files.


infra-cli is a command line tool that interfaces with the REST APIs exposed by infra-node. You can also use infra-cli to deploy and test InfraBlockchain-Antelope smart contracts.


infra-keychain is a key manager daemon for storing private keys and signing digital messages. infra-keychain provides a secure key storage medium for keys to be encrypted in the associated wallet file. The infra-keychain daemon also defines a secure enclave for signing transaction created by infra-cli or a third party library.

infra-keychain can be accessed using the wallet API, but it is important to note that the intended usage is for local light client applications. infra-keychain is not for cross network access by web applications trying to access users' wallets.


Infrablockchain.cdt is a toolchain for WebAssembly (Wasm) and a set of tools to facilitate contract writing for the InfraBlockchain-Antelope platform. In addition to being a general-purpose WebAssembly toolchain, Antelope-specific optimizations are available to support building InfraBlockchain-Antelope smart contracts. This new toolchain is built around Clang 7, which means that InfraBlockchain.cdt has most of the current optimizations and analyses from LLVM.
