Blockchain Developer
Ship production Web3 apps, smart contracts, and DeFi or NFT integrations without ad-hoc Solidity guidance.
Overview
Blockchain Developer is an agent skill most often used in Build (also Ship) that guides production-ready smart contracts, DeFi/NFT/DAO builds, and enterprise Web3 integrations.

npx skills add https://github.com/sickn33/antigravity-awesome-skills --skill blockchain-developerWhat is this skill?
- Solidity patterns: proxies, diamond standard, factory contracts
- Rust smart-contract and multi-ecosystem Web3 architecture guidance
- DeFi, NFT platforms, DAOs, and enterprise blockchain integration playbooks
- Security-first smart contract development emphasis
- Points to resources/implementation-playbook.md for deeper examples
Adoption & trust: 803 installs on skills.sh; 40.1k GitHub stars; 2/3 security scanners passed (skills.sh audits).
What problem does it solve?
You need to build or integrate on-chain systems but lack a consistent security and architecture playbook across Solidity, Rust, and multiple ecosystems.
Who is it for?
Indie builders shipping dApps, tokens, DeFi features, or internal blockchain pilots who want contract patterns and integration structure in one skill.
Skip if: Pure off-chain SaaS with no wallet or contract touchpoints, or teams that already have audited templates and only need one-line API docs.
When should I use this skill?
Working on blockchain developer tasks or workflows; needing guidance, best practices, or checklists for blockchain developer.
What do I get? / Deliverables
You get goal-aligned steps, Web3 best practices, and verifiable implementation guidance anchored to a dedicated implementation playbook when you need depth.
- Actionable implementation steps with verification
- Architecture and pattern choices for contracts and Web3 systems
- Reference path to implementation playbook for detailed examples
Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Build because the skill centers on implementing contracts, protocols, and dApp architectures—not distribution or ops runbooks. Smart contracts, chain integrations, and protocol logic are backend/system design work even when a separate frontend exists.
Where it fits
Decide whether a DAO or on-chain asset model belongs in the MVP before committing engineering time.
Implement factory-pattern Solidity contracts and chain integration for a solo-built dApp API.
Wire wallet flows and enterprise blockchain connectors alongside an existing product backend.
Apply contract security best practices and verification steps before mainnet or public testnet launch.
How it compares
Use as a Web3 build playbook in SKILL.md form—not a hosted RPC MCP server or a generic JavaScript backend skill.
Common Questions / FAQ
Who is blockchain-developer for?
Solo and indie developers building Web3 products, smart contracts, DeFi/NFT features, or enterprise chain integrations who want agent-guided architecture and security practices.
When should I use blockchain-developer?
During Build when implementing contracts and protocol logic; during Ship when hardening and reviewing contract security before release; and during Validate when scoping whether Web3 fits the product.
Is blockchain-developer safe to install?
Review the Security Audits panel on this Prism page and treat community-sourced Web3 guidance as advisory—always run independent audits before mainnet deployment.
