Tezos SmartyPy Example Box

Note: Experimental. Currently designed for demo purposes only.

This box contains a Counter and SimpleStorage contract to display the basics of Tezos SmartPy integration with Truffle.

Prerequisites

• Docker
  • Used for SmartPy compilations and running a local sandbox Tezos node.
• NodeJS
  • v8.9.4 to v12.2.0

Installation

1. Install Truffle globally. Make sure you install truffle@tezos.

npm install -g truffle@tezos

2. Download the box. This also takes care of installing the necessary dependencies.

truffle unbox tezos-smartpy-example

Usage

• Compiling the example smart contracts

  truffle compile

• Starting the local ganache-cli sandbox Tezos node

  npm run start-sandbox

• Migrating contracts

  truffle migrate

• Running contract tests

  truffle test

Sandbox Management

An archive mode ganache-cli sandbox Tezos node is provided in this box with RPC exposed at port 8732 and ten accounts generously funded with 100 XTZ. For currently supported configurable options, see the ganache-cli documentation.

Commands

npm run start-sandbox

Interacting with Live Networks

• A test faucet key can be obtained from https://faucet.tzalpha.net/. Once saved, it can be imported inside truffle-config.js:

  const { mnemonic, secret, password, email } = require("./faucet.json");
  
  module.exports = {
    networks: {
      carthagenet: {
        host: "https://carthagenet.smartpy.io",
        port: 443,
        network_id: "*",
        secret,
        mnemonic,
        password,
        email,
        type: "tezos"
      }
    }
  };

• truffle@tezos also supports importing an activated account's secret key:

  module.exports = {
    networks: {
      carthagenet: {
        host: "https://carthagenet.smartpy.io",
        port: 443,
        network_id: "*",
        secretKey: "edsk...", // private key
        type: "tezos"
      }
    }
  };

  truffle migrate --network carthagenet
  truffle test --network carthagenet
