Smart contracts development

Smart contracts are the building blocks of decentralized applications (dApps) on the TON Blockchain. If you're looking to develop your dApps, it's essential to understand how a smart contract works within the TON ecosystem.

Getting started

Use Blueprint

The following resources provide valuable information for developing smart contracts on the TON Blockchain:

• TON Hello World: Step-by-step guide for writing your first smart contract - a step-by-step guide for writing your first smart contract. Offers an accessible and concise introduction to the fundamentals of using JavaScript.
• How to work with wallet smart contracts - a detailed and structured explanation of smart contract basics, utilizing both JavaScript and Go.
• Learn smart contracts by examples - a collection of examples demonstrating smart contract development using the FunC and Fift languages.
• Speed run TON - 6 interactive challenges and step-by-step tutorials to learn smart contracts development.

DApp development

Decentralized applications (DApps) run on a peer-to-peer network—such as the TON Blockchain—rather than on a single server. They function similarly to traditional web applications but are built on a blockchain, making them decentralized, meaning no single entity controls the application.

Getting started

DeFi development

Explore key tools and concepts for building decentralized finance (DeFi) applications on the TON Blockchain:

• TON Connect — an integration and authentication for dApps.
• Off-chain payments processing — examples and concepts for processing payments.
• TON Jetton processing — examples and concepts for processing Jettons.
• Fungible (FT) / Non-fungible (NFT) tokens — smart contracts, examples, and tools.
