Blockchain & Web3
Software development skill, available on Zeplik
Blockchain & Web3 is a ready-to-run software development skill on Zeplik. Use when building smart contracts, dapps, or chain integrations -- Solidity security, DeFi protocols (staking, AMMs, governance), NFT standards (ERC-721/1155), wallets, Hardhat/Foundry testing. Ask in plain language and Zeplik applies the skill's method for you inside the conversation, on whichever AI model you prefer.
The Blockchain & Web3 skill loads automatically when your request matches it, or you can invoke it directly by typing /blockchain-web3 in any chat. It works with attachments, connectors, and any model that supports the task, so you get the same expert method every time without setting anything up.
What the Blockchain & Web3 skill can do
- Write secure Solidity contracts with pinned pragma and SPDX headers
- Implement DeFi protocols including staking, AMMs, lending, and governance
- Design NFT contracts with ERC-721/1155 metadata and royalty support
- Build Hardhat and Foundry test suites with fuzzing and invariant checks

How the Blockchain & Web3 skill works
/blockchain-web3
Umbrella skill for smart contract and web3 development: writing secure Solidity, implementing DeFi protocols (staking, AMMs, governance, flash loans), NFT standards and marketplace integration, and comprehensive contract testing with Hardhat and Foundry. The body of this skill is a dispatch table; the depth lives in references/. Pick the reference(s) matching the user's intent, read them, then answer. Security is the default posture in this lane: every contract you produce or review should be checked against the solidity-security reference, and anything handling user funds deserves explicit test coverage guidance.
Dispatch table
| Intent | Reference |
|---|---|
| DeFi protocol implementation: staking, AMMs, lending, governance, flash loans, production templates | references/defi-protocol-templates.md (+ --details) |
| NFT contracts: ERC-721, ERC-1155, metadata, minting strategies, royalties, marketplace integration | references/nft-standards.md (+ --details) |
| Contract security: common vulnerabilities, reentrancy, access control, secure Solidity patterns, audit checklists | references/solidity-security.md (+ --details) |
| Testing contracts: Hardhat and Foundry unit/integration tests, fuzzing, invariants, mainnet forking | references/web3-testing.md (+ --details) |
How to work
- Identify the intent and read the matching reference file(s) before answering; load the
--detailscompanion for depth. Contract work almost always combines references -- an NFT drop touches nft-standards plus solidity-security plus web3-testing. - Ask ONE clarifying question when the target is ambiguous: which chain/EVM version, which framework (Hardhat vs Foundry), and whether this is a new contract or an audit of existing code.
- Produce complete, compilable artifacts: full Solidity files with SPDX headers and pinned pragma, full test files, and deployment notes. For audits, list findings by severity with the vulnerable lines quoted and the fixed code shown.
- Flag economic and security risks unprompted: unchecked external calls, oracle manipulation, centralization of admin keys, upgradeability hazards. Recommend a professional audit before mainnet deployment of anything holding value.
- Redirect out-of-lane requests: generic backend or API design goes to backend-architecture; testing philosophy outside contracts goes to the relevant engineering lane.
