Solidity smart contract gas optimization guidelines based on RareSkills. Use when writing, reviewing, or auditing Solidity code. Triggers on tasks involving smart contracts, EVM development, gas optimization, or Solidity best practices.
Interact with EVM-compatible blockchains using Foundry's cast tool for querying balances, calling contracts, sending transactions, and blockchain exploration. Use when needing to interact with Ethereum Virtual Machine networks via command-line, including reading contract state, sending funds, executing contract functions, or inspecting blockchain data.
TypeScript patterns for low-level EVM blockchain interactions using Viem. Use when writing Node scripts, CLI tools, or backend services that read/write to Ethereum or EVM chains. Triggers on contract interactions, wallet operations, transaction signing, event watching, ABI encoding, or any non-React blockchain TypeScript code. Do NOT use for React/Next.js apps with hooks (use wagmi skill instead).
Blockchain smart contract specialist for Solidity, EVM, security patterns, and gas optimizationUse when "smart contract, solidity, ethereum, evm, contract, web3, gas optimization, upgradeable contract, reentrancy, solidity, ethereum, smart-contracts, evm, web3, blockchain, defi, nft, security, gas" mentioned.
Master Ethereum development including EVM, gas optimization, and client interactions
Generate, build, and deploy custom ERC20 tokens on EVM networks. Use when users want to create and deploy their own ERC20 tokens with custom parameters like name, symbol, decimals, and initial supply. Supports deployment to various networks including Sepolia testnet and requires Foundry (forge/cast) for blockchain interactions.
Validate and create x402 payment endpoint responses (HTTP 402 Payment Required). Use when the user asks to: (1) validate an x402 config or 402 response, (2) create/generate an x402 payment config, (3) build an HTTP 402 endpoint that returns payment requirements, (4) debug why an x402 config is invalid, (5) convert between x402 v1 and v2 formats, (6) check EVM/Solana addresses for x402, or (7) work with CAIP-2 network identifiers for payment configs. Triggers on keywords: x402, 402 payment, payment-required header, paywall config, CAIP-2 payment.
Use when building blockchain applications or smart contracts across EVM (Solidity), Solana (Anchor/Rust), Cosmos (CosmWasm), and TON, including security/audit workflows, fuzz/invariant testing, upgrades, custody/signing, and backend integration (RPC, indexers, webhooks).
Solidity smart contract development for Ethereum and EVM chains. Use for .sol files.
Prevent silent decimal mismatch bugs across EVM chains. Covers runtime decimal lookup, chain-aware caching, bridged-token precision drift, and safe normalization for bots, dashboards, and DeFi tools.
Deploy ERC20 tokens on Base, Ethereum, Arbitrum, and other EVM chains using the Clanker SDK. Use when the user wants to deploy a new token, create a memecoin, set up token vesting, configure airdrops, manage token rewards, claim LP fees, or update token metadata. Supports V4 deployment with vaults, airdrops, dev buys, custom market caps, vanity addresses, and multi-chain deployment.
Analyze EVM wallet asset distribution and identify high-risk protocol exposure.
