Query blockchain data across 40+ chains, create AI agents for crypto analytics, and build automated data pipelines. Use when working with blockchain data, crypto wallets, DeFi protocols, NFTs, token transfers, or on-chain analytics. Requires the Flipside CLI (https://docs.flipsidecrypto.xyz/get-started/cli).
ERC token standard implementation guidelines for Solidity. Use when implementing, extending, or reviewing ERC20, ERC721, ERC1155, or ERC4626 contracts. Covers interface compliance, common pitfalls, OpenZeppelin and Solady implementations, extension patterns, and testing strategies. Triggers on tasks involving token implementation, NFT contracts, vault standards, or ERC compliance.
Adapt React applications to MultiversX blockchain with wallet connection, transactions, and smart contract interactions. Use when app needs Web3, blockchain, wallet login, crypto payments, NFTs, tokens, or smart contract calls.
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).
Build onchain applications with React components and TypeScript utilities from Coinbase's OnchainKit. Use when users want to create crypto wallets, swap tokens, mint NFTs, build payments, display blockchain identities, or develop any onchain app functionality. Supports wallet connection, transaction building, token operations, identity management, and complete onchain app development workflows.
Configure host-based firewalls (iptables, nftables, UFW) and cloud security groups (AWS, GCP, Azure) with practical rules for common scenarios like web servers, databases, and bastion hosts. Use when exposing services, hardening servers, or implementing network segmentation with defense-in-depth strategies.
Linux networking expert for iptables, nftables, routing, DNS, and network troubleshooting
Use this skill to query Solana blockchain data via the Solscan Pro API. Triggers: look up wallet address, check token price, analyze NFT collection, inspect transaction, explore DeFi activities, get account metadata/label/tags, fetch block info, monitor API usage, search token by keyword.
