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.

Real-time blockchain event monitoring with webhooks. Use when user asks about setting up webhooks, real-time event streaming, monitoring wallet addresses, tracking token transfers in real-time, listening to all addresses on a chain, creating/updating/deleting streams, adding/removing addresses from streams, or receiving blockchain events as they happen. Supports all EVM chains. NOT for querying historical or current blockchain state - use moralis-data-api instead.
Dune Sim API for real-time blockchain wallet and token lookups across EVM and SVM chains. Use when user asks about wallet balances, token prices, NFT holdings, DeFi positions, transaction history, wallet activity, token holders, stablecoins, or any real-time on-chain data for a specific address. Triggers: 'check wallet', 'token balance', 'NFT holdings', 'DeFi positions', 'transaction history', 'token holders', 'token price', 'stablecoin balance', 'wallet activity', or any request involving a blockchain address (0x... or Solana base58).
Use this skill when the user wants to purchase a virtual debit card using crypto, create a prepaid card via x402 protocol, check virtual card status, or set up an EVM wallet for card payments. Trigger on: "buy a card", "get a virtual card", "create card", "card status", "setup wallet for card", or any intent involving purchasing virtual Visa/Mastercard with cryptocurrency.
Educational techniques to assess honeypot-style token risk from verified source, bytecode clues, and observational on-chain history—EVM ERC-20 patterns (transfer gates, fees, blacklists), Solana SPL and Token-2022 hooks, and safe validation paths. Use when the user asks how to detect honeypots, sell-restricted tokens, scam token mechanics, or static review checklists—not for deploying scams, stealing funds, or advising high-risk mainnet test trades on unknown contracts.
