Develop smart contracts | Substrate

The Develop smart contracts tutorials guide you through how you can use the ink! programming language to build smart contracts that run on a Substrate-based blockchain. The tutorials in this section use a preconfigured contracts-node and a hosted Contracts UI. If you want to use the standard node template, you need to add the Contracts pallet and a few other components to your development environment. Preparing the node template for building smart contracts is covered in Configure the contracts pallet.

Prepare your first contract describes how to update your development environment and create a smart contract project using the ink! programming language.
Develop a smart contract demonstrates how to store, increment, and retrieve simple values using a smart contract.
Use maps for storing values extends the previous tutorial by illustrating how to use maps to store and retrieve values in a smart contract.
Build a token contract illustrates how you can build a simple smart contract for transferring ERC-20 tokens.
Troubleshoot smart contracts describes a few common issues that you might encounter when writing and deploying smart contracts.
