// Smart Contract Language

Solidity

EVM-compatible smart contract development with security focus.

4+ years, 25+ contracts deployed

// Overview

How we use Solidity

Solidity is our primary language for EVM smart contract development. We use Hardhat and Foundry for testing, OpenZeppelin for battle-tested base contracts, and Slither for static analysis — security is a first-class engineering concern, not an afterthought.

// Use cases

  • ERC-20 and custom token contracts
  • NFT contracts (ERC-721, ERC-1155)
  • DeFi protocol logic
  • DAO governance contracts
  • Multi-sig and access control contracts

// Why it matters

OpenZeppelin foundations

Audited base contracts for tokens, access control, upgradeable proxies, and governance — reducing custom code surface area and attack vectors.

Foundry for testing

Foundry enables fuzz testing with Echidna-style property-based tests, fork testing against mainnet state, and fast Solidity-native test authoring.

Type safety with viem

viem + TypeScript ABI types provide fully typed contract interactions on the frontend — eliminating a class of integration errors.
