If you are getting started with Solidity development we recommend you begin by reading the tutorials outline below. They will help you understand important core concepts in Ethereum smart contract development.
Solidity Integrated Development Environments (IDE) and tools
To begin set up your development environment and select an IDE. Our recommendation is to use Remix. Then become familiar with the other development tools using the link below. These tools will help you navigate the environment and trouble shoot issues. Make sure you know how to connect your IDE to the test environments (links below).
Introduction to Solidity with Examples
- Data types
- Pure and View
- Function modifiers
- Error handling
- Fallback function
- For Loop
- Payable modifier
- Import into a contract
- Contract cleanup
- Memory vs storage
- If statements
- New keyword
- Dynamic array
- Try catch
- Account abstraction
Sample Solidity smart contracts
After reading about each of the Solidity core concepts above read the sample contracts below. Rewrite the contracts in Remix or your favorite IDE and deploy them to the test network. Practicing syntax and concepts using real examples is the best way to learn.
- Sample contract
- Address book
- Hotel contract or vending machine
- Time lock
- Simple ERC20 token contract
- Shared wallet
- Trustless token swap
- Eth game deposit and win
- Delegate call to upgrade a contract
- Covered call option
- Uniswap clone
- Multi signature wallet
- Chain link oracle
- Chain link price feeds on Binance Smart Chain
- Yield farm

Getting started with Solidity? Below is a list of EVM compatible Mainnet and Testnet blockchain networks. Each link contains network configuration, links to multiple faucets for test ETH and tokens, bridge details, and technical resources for each blockchain. Basically everything you need to test and deploy Solidity smart contracts or decentralized applications on each chain. For a list of popular Ethereum forums and chat applications click here.
