Pact makes designing safer smart contracts effortless, whether you’re writing your first contract or launching your fiftieth dApp. It’s fundamentally different from other contract languages. It’s readable by non-developers. It automatically detects bugs, freeing you from the exploits you’ll face on Ethereum and other unsafe platforms. And it has been battle-tested in production applications for over two years.

Pact Smart Contract Language

Kuro has been proven to support up to 8,000 transactions per second across 500 nodes, and is available for evaluation on AWS and Azure. Lightning+BTC powers El Salvador, but Chainweb's layer 1 scalability and Kuro's near instant finality can power the whole world.

Hello World

Language Basics

This tutorial introduces an essential feature in Pact known as modules. We’ll discuss what modules are, why they’re important, and how they relate to smart contracts.

Modules

This tutorial introduces another essential feature in Pact known as keysets. We’ll discuss what keysets are, why they’re important, and how they help regulate access to Pact modules.

Keysets

The goal of this tutorial is to get you familiar with what schemas and tables are, why they’re useful, and to demonstrate how to implement these within a Pact smart contract.

Schemas and Tables

The goal of this tutorial is to get you up and running with the Pact environment and the Pact Atom SDK to begin running Pact programs locally.

Atom SDK

The goal of this tutorial is to help you build an application that transfers value between two accounts. To do this, you’ll build a smart contract that implements this functionality named Simple Payments. This is an important function of smart contracts and will set you up to create more complex applications using accounts and transfers.

Accounts and Transfers

The goal of this tutorial is to learn the basics of building interactions between modules in Pact. You will go over some of the fundamentals, then build a smart contract that allows users to both make and authorize payments using multiple Pact modules.

Contract Interaction

Here you’ll create a smart contract named Rotatable Wallets that demonstrates many important Pact features that you learned throughout previous tutorials.

Rotatable Wallet

In this tutorial, you will build an example loans application using many of the techniques you learned in earlier tutorials

Loans

In this tutorial, you will learn the basics of testing in the SDK to build your own REPL file. This is a great start to begin testing the smart contracts you build locally.

Test in the SDK

Welcome to Pact

The goal of this tutorial is to help you connect your Pact development environment to a front end application.

Pact and JavaScript

In this tutorial, we’ll focus specifically on how Pact approaches control flow to ensure safety.

Safety Using Control Flow

Throughout this tutorial you’ll learn why interfaces are valuable and how to implement them with Pact.

Interfaces with Pact

In this guide, we will go through and explain specific built-in functions that are listed in the pact reference page

Built in Functions

The goal of this tutorial is to help you run and deploy a working Pact test server locally.
