# Smart Contracts

The **Develop smart contracts** tutorials guide you through how you can use [the ink! programming language](https://use.ink) to build smart contracts that run on a Substrate-based blockchain.

The tutorials in this section use a preconfigured [`substrate-contracts-node`](https://github.com/paritytech/substrate-contracts-node) to keep your work focused on the basics of writing smart contracts.

If you use the [standard node template](https://github.com/substrate-developer-hub/substrate-node-template), you must manually add the [Contracts pallet](https://github.com/paritytech/polkadot-sdk/tree/master/substrate/frame/contracts) and make other changes to your development environment. You can compare the runtime code for the two nodes to see additional information about the differences between them.

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