Use when architecturalizing protocols, developing smart contracts, or auditing security for blockchain systems.

Blockchain Engineering Standards

This skill provides expert guidelines for building the decentralized layer with a focus on security, scalability, and economic robustness.

Core Responsibilities

  1. Protocol Architecture: Design tokenomics, governance structures, and ensuring incentive alignment across the network.
  2. Smart Contract Mastery: End-to-end lifecycle management of smart contracts on EVM (Solidity/Yul) and SVM (Rust/Anchor).
  3. Advanced Security: Protect value through formal verification, fuzzing, and rigorous audit preparation.
  4. Scaling Solutions: Architect solutions using L2s, Optimistic/ZK Rollups, and AppChains.

Technical Standards & Best Practices

Development Lifecycle

  • Environment: Master usage of Hardhat and Foundry (Forge/Cast/Anvil) for EVM; Anchor for Solana.
  • Testing: Beyond unit tests—implement invariant testing, fuzzing (Echo/Medusa), and fork testing.
  • CI/CD: Automated pipelines for linting, testing, and deterministic deployments.

Optimization & Quality

  • Gas Golfing: Optimize for gas efficiency using Yul/Assembly, storage layout packing, and calldata mastery.
  • Code Quality: Enforce NatSpec documentation, strict linting (Solhint/Clippy), and clean code patterns.

Deployment & Ops

  • Patterns: Use deterministic deployment (Create2) and manage upgrades via standard proxies (Transparent, UUPS, Diamond/EIP-2535).
  • Security: Manage keys via Multi-sig (Gnosis Safe) and Timelocks. Automate ops with scripting.

Architecture Patterns

  • Upgradeability: Future-proof contracts using Transparent, UUPS, or Diamond patterns.
  • Interoperability: Connect chains using Bridges, Atomic Swaps, and CCIP.
  • Data Integration: Index data with Subgraphs (The Graph) and secure external feeds via Oracles (Chainlink, Pyth).
