What problem does it solve?

This Skill helps you design, implement, debug, and verify Solidity smart contracts and common Web3 protocol patterns without getting stuck on the many framework, security, and testing decisions.

Core Features & Use Cases

  • Architecture decision support: Choose the right contract standard and protocol shape for tokens, NFTs, DeFi components, governance, bridges, and smart-account flows (ERC-20/721/1155, ERC-4626, ERC-4337, Governor/Timelock).
  • Testing and verification guidance: Map unit/integration/fork/invariant/fuzz/formal-security approaches to the right toolchain (Foundry, slither, symbolic/static checks).
  • Security and gas-focused implementation patterns: Apply CEI and reentrancy protections, access control best practices, anti-MEV/oracle guidance, and common gas optimizations.

Quick Start

Use the blockchain-web3 skill to plan and implement a secure ERC-20 staking contract with Foundry tests, including a fuzz/invariant strategy and a security checklist for reentrancy, access control, and oracle assumptions.
