Solidity

The reference language for smart contracts on Ethereum and the EVM.

Solidity is a statically typed, contract-oriented language that compiles to EVM bytecode, Ethereum's virtual machine. It's the standard for writing on-chain smart contracts — ERC-20 tokens, ERC-721 NFTs, DeFi protocols, DAOs — deployable on Ethereum and every EVM-compatible chain (Polygon, Arbitrum, Base, BNB Chain).

[ Why Solidity ]

What Solidity brings to your project.

Typical use cases: DeFi smart contracts, tokens and NFT collections on Ethereum and EVM L2s.

  1. 01

    Statically typed and contract-oriented: inheritance, modifiers, interfaces.

  2. 02

    ERC standards (20, 721, 1155) and battle-tested OpenZeppelin libraries.

  3. 03

    Mature tooling: Hardhat, Foundry, Remix, testing and fuzzing.

  4. 04

    Portable across every EVM chain with no code rewrite.
