Instant, zero-config Terra blockchain and ecosystem.


What is LocalTerra?

LocalTerra is a complete Terra testnet and ecosystem containerized with Docker and orchestrated with a simple docker-compose file, designed to make it easy for smart contract developers to test out their contracts on a sandboxed environment before moving to a live testnet or mainnet.

LocalTerra comes pre-configured with opinionated, sensible defaults for a standard testing environment. If other projects mention testing on LocalTerra, they are referring to the settings defined in this repo.

The advantages of LocalTerra over a public testnet are that:

  • world state is easily modifiable
  • quick to reset for quick iterations
  • easy to simulate different scenarios
  • validator behavior is controllable

Requirements

Usage

$ git clone https://www.github.com/terra-project/LocalTerra
$ cd LocalTerra

Make sure your Docker daemon is running in the background and docker-compose is installed. Then start LocalTerra:

$ docker-compose up

You should now have an environment with the following:

If you need to turn off LocalTerra:

$ docker-compose down

To reset the world state, issue the following:

$ docker-compose rm

LocalTerra and...

Terra Station

Terra Station has built-in support for LocalTerra, which enables you to interact with your LocalTerra. Open up station and switch to the Localterra network:

station_localterra

terracli

Make sure you have the same version of terracli installed as LocalTerra. Then, you can use terracli to talk to your LocalTerra terrad node:

$ terracli status

This automatically works because terracli connects to localhost:26657 by default. More explicitly:

$ terracli status --node=tcp://localhost:26657

You should now be able to issue normal commands with terracli against your LocalTerra network:

$ terracli query account terra1dcegyrekltswvyy0xy69ydgxn9x8x32zdtapd8

Jigu

You can connect to the chain through LocalTerra's LCD server.

from jigu import Terra
terra = Terra("localterra", "http://localhost:1317")

Terra.js

You can connect to the chain using LCDClient against LocalTerra's LCD server.

import { LCDClient } from "@terra-money/terra.js";

const terra = new LCDClient({
  URL: "http://localhost:1317",
  chainId: "localterra",
});

Configuring LocalTerra

Since the majority of LocalTerra is implemented through a docker-compose.yml file, it is easily customizable and can be considered a starting template point for setting up your own local Terra testnet with Docker containers. Out-of-the-box, LocalTerra comes preconfigured with opinionated settings such as:

  • ports defined for RPC (26657), LCD (1317) and FCD (3060)
  • standard accounts (shown below)

Modifying Node Configuration

You can modify the node configuration of your validator in config/config.toml and config/app.toml.

Modifying Genesis

If you need to change the genesis.json file, you can alter it in config/genesis.json. This will get loaded when you reset your LocalTerra network.

Accounts

LocalTerra is pre-configured with one validator and 10 accounts with LUNA balances.
