What problem does it solve? AI agents and developers often jump straight into writing Solidity without an architecture plan, over-engineer contracts, pick the wrong chain, or skip security and QA — leading to rewrites, vulnerabilities, and failed launches. This Skill provides a phased, opinionated workflow that routes you from dApp idea to deployed production app. ## Core Features & Use Cases - Architecture Planning (Phase 0): CROPS gate (Censorship Resistance, Open Source, Privacy, Security), onchain vs offchain litmus test, MVP contract count guidance, state transition audits, and chain selection across mainnet, Base, Arbitrum, Optimism, and ZK chains. - dApp Archetype Templates: Predefined contract architectures for token launches, NFT collections, marketplaces, lending/vaults, DAOs, and AI agent services, each with common mistakes and fetch sequences. - Phased Build Pipeline: Step-by-step guidance for writing contracts with OpenZeppelin, testing with Foundry (unit, fuzz, fork), auditing with a fresh agent, building frontends with Scaffold-ETH 2, and shipping to IPFS or Vercel. - Use Case: You want to launch a prediction market. The Skill tells you it needs 1-2 contracts (market + resolution oracle), routes you through security and testing skills, and walks you through deployment, multisig ownership transfer, and post-launch monitoring. ## Quick Start Ask the agent to plan and ship your dApp idea, starting with the architecture phase before writing any Solidity code.
