Spin up a multi-validator Terra Classic Core network locally with `make localnet-start`.

Prerequisites

  • git, make, Docker, and Docker Compose (depending on your setup)
  • 16-32 GB RAM recommended

Steps

  1. Clone the repository:

    BASH
    git clone https://github.com/classic-terra/core.git terra-core
cd terra-core

  2. Start a localnet:

    BASH
    make localnet-start

    This spins up a multi-validator local network with RPC and LCD endpoints. Keep it running in the background while you develop.

  3. Endpoints (typical defaults):

    • RPC: http://localhost:26657Copy http://localhost:26657
    • LCD: http://localhost:1317Copy http://localhost:1317
    • gRPC: http://localhost:9090Copy http://localhost:9090

  4. Chain ID:

    • Usually localterraCopy localterra or localnetCopy localnet (check the console output). Use this in your SDK configuration.

Using with CosmES

Example Keplr setup against localnet:

TS
import { KeplrController, WalletType } from "@goblinhunt/cosmes/wallet";

const controller = new KeplrController("<YOUR_WC_PROJECT_ID>");
const wallets = await controller.connect(WalletType.EXTENSION, [
  {
    chainId: "localterra", // or "localnet"
    rpc: "http://localhost:26657",
    gasPrice: { denom: "uluna", amount: "28.325" },
  },
]);
const connected = wallets.get("localterra");
console.log("address", connected?.address);

Warning

Make sure to add the chain information to keplr before connecting.

Tips

  • If ports conflict, stop other chain processes or change ports in Terra Core configs.
  • For contract workflows, use the same Msg*Copy Msg* transactions in CosmES as on mainnet or testnet—only the endpoints and chain ID change.
