Practical overview
When it fits
Use Terrain to generate a Terra/CosmWasm application project and work through its documented contract deployment flow. The README recommends LocalTerra for testing and requires an RPC endpoint for deployment.
Who it is for
- Developers starting Terra or CosmWasm interchain application projects.
- Contract developers who want a generated frontend and project structure alongside a smart-contract template.
Documented uses
- Scaffold a starter contract and corresponding frontend.
- Create a structured project with predefined task helpers and connection and deployment configuration.
- Build, optimize, store, and instantiate a contract through Terrain’s deployment command.
Requirements & limits
Terrain is open-source software licensed under GPL-3.0 and distributed as an npm package.
- Terrain is a development environment, not a full Terra client or an LCD; the README points to terrad for full client functionality.
- Contract deployment needs an RPC endpoint. LocalTerra is the README’s recommended testing option.
- The documented runtime prerequisite is Node.js 16 with npm; the setup also recommends Rust and lists the CosmWasm build dependencies.
- The repository identifies TypeScript as its primary language.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Scaffold an interchain contract and frontend project
Generate a Terrain project containing smart-contract and frontend templates.
Before you start
- Node.js 16 and npm.
- Terrain installed globally, or locally in the project directory.
Steps
Install Terrain with npm: the command below.
npm install -g @terra-money/terrainGenerate the project with
terrain new my-terra-dapp.Change to the generated project directory with
cd my-terra-dapp.
Expected outcome
A project with a template smart contract, frontend, supporting task and console files, and Terrain configuration and reference files.
Guide limitations
- This procedure scaffolds a project; it does not deploy the contract.
- The README also documents local installation with npm and running commands through npx.
Deploy a generated contract to LocalTerra
Use Terrain’s documented deployment command to build and instantiate a contract on a local chain.
Before you start
- A generated Terrain project and Node.js 16/npm.
- LocalTerra running locally, as recommended for testing.
- A configured RPC endpoint and signer account; the example uses LocalTerra’s preconfigured
test1account. - Rust stable, the
wasm32-unknown-unknowntarget, andcargo-run-script, as specified in the setup instructions.
Steps
Set up and run LocalTerra using its repository instructions; the Terrain README shows
docker-compose upfrom the LocalTerra directory.From the Terrain project, run
terrain deploy my-terra-dapp --signer test1.If needed, add the
--networkflag to specify a network; without it, the README says the command defaults tolocalterra.
Expected outcome
Terrain builds and optimizes the Wasm code, stores it on-chain, and instantiates the contract.
Guide limitations
- Deployment requires an RPC endpoint; Terrain is not an LCD.
- The signer pays the deployment gas fee and is assigned as project owner. The documented
test1signer is a LocalTerra example.
