Solidity Resources

Most development resources for developing with Soldity on Ethereum Mainnet also apply to development on Sei.

This page suggests a minimal set of resources for getting started with building a decentralized app for Sei EVM.

IDEs

Remix
An interactive Solidity IDE that is the easiest and fastest way to start coding and compiling Solidity smart contracts without any additional installations.
VSCode + Solidity extension

CryptoZombies
A great end-to-end introduction to building dApps on the EVM. It offers lessons suitable for complete beginners as well as developers from other disciplines.
Solidity by Example
Introduces Solidity concepts progressively through simple examples – ideal for developers with some programming background.
Blockchain Basics course by Cyfrin Updraft
Covers the fundamentals of blockchain, DeFi, and smart contracts.
Solidity Smart Contract Development by Cyfrin Updraft
Offers hands-on experience to become a smart contract developer.
Ethereum Developer Degree by LearnWeb3
A course designed to take you from no background in web3 to building multiple applications and understanding key protocols, frameworks, and concepts.

The Solidity Language
Official documentation providing an end-to-end description of smart contracts, blockchain basics, compiling, and deployment on an EVM.
Solidity Patterns
A repository of code templates with explanations of their usage.
Cookbook.dev
Offers interactive example template contracts with live editing, one-click deploy, and an AI chat integration for coding help.
OpenZeppelin
Provides a library of customizable template contracts for common Ethereum token deployments (e.g., ERC20, ERC721, ERC1155). Note that these are not gas optimized.
Uniswap
A professional, easy-to-digest smart contract of the Uniswap V2 pools that gives an overview of an in-production Solidity dApp. A guided walkthrough is available here . For the more advanced Uniswap Pools, check out the Uniswap V3 here and Uniswap V4 here .
