Terrain

THIS REPO IS ARCHIVED IN FAVOR OF terra-money/terrain.

@iboss-ptk, original author, is actively working on similar tool called Beaker. That is started on Osmosis, but designed be adaptable on every cosmwasm enabled chain.

Terrain

Terrain – Terra development environment for better smart contract development experience

Terrain will help you:

scaffold your dapp project
ease the development and deployment process
create custom task for blockchain and contract interaction with less boilerplate code
- using terra.js directly could be cumbersome, Terrain gives you extensions and utilities to help you
console to terra blockchain, an interactive repl which have the same extensions and utilities as custom task
ability to predefine functions to be used in task and console

Terrain
Setup
set 'stable' as default release channel (used when updating rust)
add wasm as compilation target
for generating contract
Getting Started
for first time, you might want to npm install -g @iboss/terrain
or run npx @iboss/terrain new my-terra-dapp
since terrain npm module name is occupied by another module
Migrating CosmWasm contracts on Terra
Usage
Commands

Setup

Download LocalTerra

For local developement environment, you need LocalTerra.

note: if you are using m1 chip, you might need to update your Docker Desktop due to qemu bug

git clone --branch v0.5.2 --depth 1 https://github.com/terra-money/localterra
cd localterra
docker-compose up

Setup Rust

While WASM smart contracts can theoretically be written in any programming language, we currently only recommend using Rust as it is the only language for which mature libraries and tooling exist for CosmWasm. For this tutorial, you'll need to also install the latest version of Rust by following the instructions here.

Then run the following commands

# set 'stable' as default release channel (used when updating rust)
rustup default stable

# add wasm as compilation target
rustup target add wasm32-unknown-unknown

# for generating contract
cargo install cargo-generate --features vendored-openssl
cargo install cargo-run-script

Getting Started

Assumed that you have npm installed, let's generate our first app

# for first time, you might want to `npm install -g @iboss/terrain` 
# or run `npx @iboss/terrain new my-terra-dapp`
# since `terrain` npm module name is occupied by another module
npx terrain new my-terra-dapp
cd my-terra-dapp
npm install

Project Structure

The project structure will look like this:

.
├── contracts              # contracts' source code
│   ├── counter
│   └── ...                # more contract can be added here
├── frontend               # frontend application
├── lib                    # predefined functions for task and console
├── tasks                  # predefined tasks
├── keys.terrain.js        # keys for signing transacitons
├── config.terrain.json    # config for connections and contract deployments
└── refs.terrain.json      # deployed code and contract referecnes

You will now have counter example contract (no pun intended).

Deployment

We can right away deploy the contract on LocalTerra. Not specifying network will be defaulted to localterra.

npx terrain deploy counter --signer validator

npx will use project's terrain binary instead of the global one.

note that signer validator is one of a pre-configured accounts with balances on LocalTerra.

Deploy command will build and optimize wasm code, store it on the blockchain and instantiate the contract.

You can deploy to different network defined in the config.terrain.json (mainnet and testnet). But you can not use the pre-configured accounts anymore. So you need to first update your keys.terrain.js

// can use `process.env.SECRET_MNEMONIC` or `process.env.SECRET_PRIV_KEY`
// to populate secret in CI environment instead of hardcoding

module.exports = {
  custom_tester_1: {
    mnemonic:
      "shiver position copy catalog upset verify cheap library enjoy extend second peasant basic kit polar business document shrug pass chuckle lottery blind ecology stand",
  },
  custom_tester_2: {
    privateKey: "fGl1yNoUnnNUqTUXXhxH9vJU0htlz9lWwBt3fQw+ixw=",
  },
};

Apparently, there are some example accounts pre-defined in there. But DON'T USE THEM ON MAINNET since it is not a secret anymore.

For demonstration purpose, we are going to use custom_tester_1.

First, get some Luna from the faucet to pay for gas. Notice that it requires address but you only have mnenomic or private_key in keys.terrain.js.

The easiest way to retrive the address is to use console:

npx terrain console

terrain > wallets.custom_tester_1.key.accAddress
'terra1qd9fwwgnwmwlu2csv49fgtum3rgms64s8tcavp'

Now you can request for Luna on the faucet then check your balance in console.

terrain > (await client.bank.balance(wallets.custom_tester_1.key.accAddress))[0]

client is an LCDClient (LCD stands for "Light Client Daemon" as opposed to FCD a "Fulll Client Daemon", if you are curious) with some extra utility function. And wallets contains list of Wallet.

npx terrain deploy counter --signer custom_tester_1 --network testnet

Same goes for mainnet deployment, you might want to store your secrets in enviroment variable instead, which you can populate them through process.env.SOME_SECRET in keys.terrain.json.

You can also separate storing code from contract instantiation as using:

terrain code:store CONTRACT
terrain contract:instantiate CONTRACT

After deployment, refs.terrain.json will get updated. Refs file contains contract references on all network.

{
  "localterra": {
    "counter": {
      "codeId": "1",
      "contractAddresses": {
        "default": "terra18vd8fpwxzck93qlwghaj6arh4p7c5n896xzem5"
      }
    }
  },
  "testnet": {
    "counter": {
      "codeId": "18160",
      "contractAddresses": {
        "default": "terra15faphq99pap3fr0dwk46826uqr2usve739l7ms"
      }
    }
  }
}

This information is used by terrain's utility functions and also the frontend template.

But in order to use it with frontend, You sync this in to frontend/src since it can not import file outside its rootDir (src). Todo so, run:

npx terrain sync-refs

This is not ideal, ideas and contribution are more than welcome

With this, we can now start frontend:

cd frontend
npm run start

Switching network in your terra wallet extension will result in referencing to different contract address in the respective network.

Lib, Console and Task

With the template setup, you can do this

npx terrain console
terrain > await lib.increment()
...
terrain > await lib.getCount()
{ count: 0 }

npx terrain console --network <NETWORK> is also possible

Where does this lib functions comes from?

The answer is here:

// lib/index.js

module.exports = ({ wallets, refs, config, client }) => ({
  getCount: () => client.query("counter", { get_count: {} }),
  increment: (signer = wallets.validator) =>
    client.execute(signer, "counter", { increment: {} }),
});

With this, you can interact with your contract or the blockchain interactively with your own abstractions.

You can use the lib to create task as well:

// tasks/example-with-lib.js

const { task } = require("@iboss/terrain");
const lib = require("../lib");

task(async (env) => {
  const { getCount, increment } = lib(env);
  console.log("count 1 = ", await getCount());
  await increment();
  console.log("count 2 = ", await getCount());
});

To run this task:

npx terrain task:run example-with-lib

To create new task, run:

npx terrain task:new task-name

You might noticed by now that the env (wallets, refs, config, client) in task and lib are the ones that available in the console context.

Also, you can access terrajs in the console or import it in the lib or task to create custom interaction like in tasks/example-custom-logic.js or more complex one, if you are willing to do so, please consult terra.js doc.

// tasks/example-custom-logic.js

const { task, terrajs } = require("@iboss/terrain");

// terrajs is basically re-exported terra.js (https://terra-money.github.io/terra.js/)

task(async ({ wallets, refs, config, client }) => {
  console.log("creating new key");
  const key = terrajs.MnemonicKey();
  console.log("private key", key.privateKey.toString("base64"));
  console.log("mnemonic", key.mnemonic);
});

Migrating CosmWasm contracts on Terra

(Thanks to @octalmage)

On Terra it is possible to initilize contracts as migratable. This functionallity allows the adminstrator to upload a new version of the contract, then send a migrate message to move to the new code.

We'll be using Terrain, a Terra development suite to ease the scaffolding, deployment, and migration of our contracts.

This tutorial builds on top of the Terrain quick start guide: https://docs.terra.money/Tutorials/Quick-start/Initial-setup.html

Adding MigrateMsg to contract

There's two steps required to make a contract migratable:

Smart contract handles the MigrateMsg transaction.
Smart contract has an admin set, which is the address that's allowed to perform migrations.

To implement support for MigrateMsg you will need to add the message to msg.rs:

#[derive(Serialize, Deserialize, Clone, Debug, PartialEq, JsonSchema)]
pub struct MigrateMsg {}

You can place this anywhere, I usually stick it above the InstantiateMsg struct.

With MigrateMsg defined we need to update contract.rs. First update the import from crate::msg to include MigrateMsg:

use crate::msg::{CountResponse, ExecuteMsg, InstantiateMsg, QueryMsg, MigrateMsg};

Then add the following method above instantiate:

#[cfg_attr(not(feature = "library"), entry_point)]
pub fn migrate(_deps: DepsMut, _env: Env, _msg: MigrateMsg) -> StdResult<Response> {
    Ok(Response::default())
}

Calling migrate

In the previous Terrain tutorial we showed you how to deploy the contract, but we did not initilize it as migratable.

After adding MigrateMsg to the smart contract we can redeploy and add the --set-signer-as-admin flag. This tells Terra that the transaction signer is allowed to migrate the contract in the future.

npx terrain deploy counter --signer validator --set-signer-as-admin

With the new contract deployed you can make some changes, then migrate to the new code with the following command:

npx terrain contract:migrate counter --signer validator
