Add an ERC-721 NFT contract to a Scaffold-ETH 2 project. Use when the user wants to: create an NFT collection, deploy an ERC-721, add NFT minting, build an NFT gallery or transfer UI, or work with non-fungible tokens in SE-2.
AlgoKit CLI commands for building, testing, and deploying Algorand applications. Use when building or compiling smart contracts, running test suites, deploying to localnet, managing local Algorand network, or understanding the development workflow. Strong triggers include "build the contract", "run the tests", "start localnet", "deploy to localnet", "algokit project run", "localnet status".
Solidity smart contract development workflow. Use when modifying smart contracts in apps/eth-contracts/contracts/.
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 Stylus smart contract project with OpenZeppelin Contracts for Stylus on Arbitrum. Use when users need to: (1) install Rust toolchain and WASM target for Stylus, (2) create a new Cargo Stylus project, (3) add OpenZeppelin Stylus dependencies to Cargo.toml, or (4) understand Stylus import conventions and storage patterns for OpenZeppelin.
Solidity security patterns, common vulnerabilities, and pre-deploy audit checklist. The specific code patterns that prevent real losses — not just warnings, but defensive implementations. Use before deploying any contract, when reviewing code, or when building anything that holds or moves value.
Expert guidelines for Ethereum smart contract development with Solidity, OpenZeppelin, and Hardhat
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.
Master smart contract security best practices, vulnerability prevention, and secure Solidity development patterns.
[AUTO-INVOKE] MUST be invoked BEFORE writing or modifying any Solidity contract (.sol files). Covers private key handling, access control, reentrancy prevention, gas safety, and pre-audit checklists. Trigger: any task involving creating, editing, or reviewing .sol source files.
Create production grade smart contracts. Use this skill when the user asks to write smart contracts, specially if they are going to be deployed to production (to a mainnet, or used in a mainnet script).
Security audit of Solidity code while you develop. Trigger on "audit", "check this contract", "review for security". Modes - default (full repo) or a specific filename.
