Blockchain Developer: the all-in-one AI plugin

Skills for blockchain developers 17

• code debugging assistantTroubleshoots errors and stack traces, for example when a Hardhat deploy fails with a nonce or gas error.
• blockchain developerBuilds full Web3 features end to end, for example an ERC-20 staking contract plus its front end and deploy scripts.
• agency engineering solidity smart contract engineerHandles Solidity architecture, gas tuning, and upgradeable proxies, for example converting a contract to a UUPS proxy.
• solidity securityApplies secure Solidity patterns and fixes, for example adding a reentrancy guard to a withdraw function.
• agency engineering code reviewerReviews a pull request or diff with actionable feedback, for example flagging an unchecked external call before merge.
• test runnerRuns the test suite and explains failures, for example why a Foundry fuzz test fails only on large inputs.

Plus a start-here assistant, the prompt library and the app builder, and for members the daily brief.

Apps you can build with AI 6

• Source-linked code review and security consoleBuild this to catch security issues before merge while keeping reviewer control over every contract change. Demo included.
• Source-linked AI coding and review consoleBuild this to cut tool sprawl while every smart contract change stays under team review. Demo included.
• Source-linked code assistant and admin consoleBuild this to keep code, context, and review evidence in one workspace your team owns. Demo included.
• Source-linked test generation and maintenance consoleBuild this to keep contract tests current in your own repository without manual upkeep. Demo included.
• Source-linked code review and debugging consoleBuild this to shorten review and debugging cycles with a named engineer approving each change. Demo included.
• Source-linked code assistant and admin consoleBuild this to keep code and review evidence inside your own environment instead of scattered tools. Demo included.

AI agents 12

In the download. An agent runs a whole recurring task for you, step by step, and asks you before anything important. Ask your AI: "Run the Product Documentation Task Test Agent". Each one also has a guided set-up with sample data on its page.

• Product Documentation Task Test AgentDocs examples that work exactly as written.
• Blockchain Use Case Feasibility Screen AgentA fair, documented screen of a blockchain proposal with a clear recommendation
• Test Coverage Gap Closing AgentAdd tests to the riskiest untested code and prove that they catch real bugs
• Contract Static Analysis Triage AgentFind the real vulnerabilities among analyzer output and confirm each with a test
• Audit Finding Fix Verification AgentProve each audit fix works and breaks nothing else, with evidence for the auditors
• Oracle Dependency Risk AgentKnow what each external dependency can do to the contract and add safeguards that are tested
• Governance Proposal Impact AgentShow exactly what a proposal will change before the team votes
• Pull Request Review Prep AgentA pull request that passes checks and has a complete description before a human reviews it
• Stack Trace Root Cause AgentA reproduced bug with a proposed fix and a regression test
• API Integration Build AgentA working, tested integration with auth, error handling and field mapping
• Smart Contract Test and Review AgentA well-tested contract with known gas cost and reviewed risks before deployment
• Blockchain Event Indexer Health AgentThe indexer stays close to the chain head with no missing events

Connections (MCP servers) 12

A guide in the download. A connection lets your AI work in an app you already use. You add only the ones you use: ask your AI "Which apps can you connect to?" and follow the steps on each connection's page.

• OpenZeppelin Contracts MCP serverLets your AI generate ready-to-use smart contract code from OpenZeppelin templates when you ask. No install needed.
• Klever MCP serverLets your AI look up Klever blockchain code patterns, examples, and best practices while you build. Official. No install needed.
• EVM Blockchain MCP serverLets your AI read and simulate transactions on Ethereum and other blockchains for you.
• ARBuilder MCP serverLets your AI write Arbitrum code: Stylus contracts, bridges, full dApps, and Orbit chain setups. No install needed.
• Pentagonal MCP serverLet your AI check, audit, fix and write smart contracts for Ethereum, Solana and other chains. No install needed.
• M2M Sentinel MCP serverLets your AI check what a Base blockchain contract can actually do before you trust it. No install needed.
