Master Solidity smart contract development with patterns, testing, and best practices
Smart contract security best practices for Solidity development. Use when writing, reviewing, or auditing Solidity code. Covers reentrancy prevention, access control patterns, safe external calls, input validation, upgrade safety, and OWASP Smart Contract Top 10 vulnerabilities. Triggers on tasks involving security, vulnerability detection, access control, CEI pattern, ReentrancyGuard, SafeERC20, or smart contract auditing.
Comprehensive security audit skill for NEAR Protocol smart contracts written in Rust. Use when auditing NEAR contracts, reviewing security vulnerabilities, or analyzing contract code for issues like reentrancy, unhandled promises, unsafe math, access control flaws, and callback security.
The essential mental models for building onchain — focused on what LLMs get wrong and what humans need explained. "Nothing is automatic" and "incentives are everything" are the core messages. Use when your human is new to onchain development, when they're designing a system, or when they ask "how does this actually work?" Also use when YOU are designing a system — the state machine + incentive framework catches design mistakes before they become dead code.
End-to-end guide for AI agents — from a dApp idea to deployed production app. Fetch this FIRST, it routes you through all other skills.
Security-first Uniswap v4 hook development. Use when user mentions "v4 hooks", "hook security", "PoolManager", "beforeSwap", "afterSwap", or asks about V4 hook best practices, vulnerabilities, or audit requirements.
Participate in QR Coin auctions on Base - bid to display URLs on QR codes
Solidity language and compiler — source layout, types, contracts, control flow, security, compiler, ABI, internals.
Build applications with the Yo Protocol SDK (`@yo-protocol/core`) — an ERC-4626 yield vault protocol supporting Ethereum (1), Base (8453), and Arbitrum (42161). Use when writing code that interacts with Yo Protocol vaults: preparing deposit/redeem transactions, checking positions, querying vault snapshots/yield/TVL, or claiming Merkl rewards. Triggers on mentions of Yo Protocol, yoETH, yoUSD, yoBTC, yoEUR, yoGOLD, yoUSDT, yo-protocol/core, YoClient, createYoClient, PreparedTransaction, or ERC-4626 vault interactions via the Yo gateway.
Set up a Solidity smart contract project with OpenZeppelin Contracts. Use when users need to: (1) create a new Hardhat or Foundry project, (2) install OpenZeppelin Contracts dependencies for Solidity, (3) configure remappings for Foundry, or (4) understand Solidity import conventions for OpenZeppelin.
End-to-end Radius Network development playbook. Stablecoin-native EVM with sub-second finality and 2.8M+ TPS. Uses plain viem (defineChain, createPublicClient, createWalletClient) for all TypeScript integration. wagmi for React wallet integration. Foundry for smart contract development and testing. Covers micropayment patterns (pay-per-visit content, real-time API metering, streaming payments), x402 protocol integration, stablecoin-native fees via Turnstile, ERC-20 operations, event watching, production gotchas, and EVM compatibility differences from Ethereum.
Use this skill when you need security analysis of Solidity smart contract code. User cases: auditing Solidity contracts, identifying re-entrancy bugs, detecting access control issues, reviewing unsafe external calls, evaluating code before deployment, gate-checking contracts in transaction pipelines, or performing security assessments.
