Check cryptocurrency wallet balances, token holdings, transaction history, token approvals, ENS name resolution, and on-chain activity. Use when asked about wallet balance, what tokens an address holds, transaction history, pending transactions, token allowances, ENS lookup, or address portfolio.

End-to-end Solana development playbook (Jan 2026). Prefer Solana Foundation framework-kit (@solana/client + @solana/react-hooks) for React/Next.js UI. Prefer @solana/kit for all new client/RPC/transaction code. When legacy dependencies require web3.js, isolate it behind @solana/web3-compat (or @solana/web3.js as a true legacy fallback). Covers wallet-standard-first connection (incl. ConnectorKit), Anchor/Pinocchio programs, Codama-based client generation, LiteSVM/Mollusk/Surfpool testing, and security checklists.

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.

Query blockchain data via Allium APIs. Token prices, wallet balances, transactions, historical data. Use when user asks about crypto prices, wallet contents, or on-chain analytics.

Choose and implement the right Circle wallet type for your application. Compares developer-controlled, user-controlled, and modular (passkey) wallets across custody model, key management, account types, blockchain support, and use cases. Use whenever blockchain wallet integrations are required for onchain application development. Triggers on: circle wallets, blockchain wallets, choose wallet, wallet comparison, which wallet, wallet types, EOA vs SCA vs MSCA, custody model, embedded wallet, smart account, programmable wallets, create wallet, onchain wallet.

Provide instructions on how to build with Arc, Circle's blockchain where USDC is the native gas token. Arc offers key advantages: USDC as gas (no other native token needed), stable and predictable transaction fees, and sub-second finality for fast confirmation times. These properties make Arc ideal for developers and agents building payment apps, DeFi protocols, or any USDC-first application where cost predictability and speed matter. Use skill when Arc or Arc Testnet is mentioned, working with any smart contracts related to Arc, configuring Arc in blockchain projects, bridging USDC to Arc via CCTP, or building USDC-first applications. Triggers: Arc, Arc Testnet, USDC gas, deploy to Arc, Arc chain, stable fees, fast finality.

Bitcoin L1 wallet for agents - check balances, send BTC, manage UTXOs. Extends to Stacks L2 (STX, DeFi) and Pillar smart wallets (sBTC yield).

This skill should be used when the user asks to 'check my wallet balance', 'show my token holdings', 'how much OKB do I have', 'what tokens do I have', 'check my portfolio value', 'view my assets', 'how much is my portfolio worth', 'what\\'s in my wallet', or mentions checking wallet balance, total assets, token holdings, portfolio value, remaining funds, DeFi positions, or multi-chain balance lookup. Supports XLayer, Solana, Ethereum, Base, BSC, Arbitrum, Polygon, and 20+ other chains. Do NOT use for general programming questions about balance variables or API documentation. Do NOT use when the user is asking how to build or integrate a balance feature into code.

Query any on-chain wallet address token balances and positions. Retrieves all token holdings for a specified wallet address on a given chain, including token name, symbol, price, 24h price change, and holding quantity. Use this skill when users ask about wallet balance, token holds, portfolio, or asset positions for any blockchain address.

Binance Onchain Pay enables users to buy cryptocurrency with fiat (e.g., EUR, USD) or send existing crypto from their Binance account directly to any external on-chain wallet address in a single flow—no manual withdrawal needed. Enables partners to integrate crypto buying services: - payment-method-list: Get available payment methods (Card, P2P, Google Pay, Apple Pay, etc.) with limits for a fiat/crypto pair - trading-pairs: List all supported fiat currencies and cryptocurrencies - estimated-quote: Get real-time price quote including exchange rate, fees, and estimated crypto amount - pre-order: Create a buy order and get redirect URL to Binance payment flow - order: Query order status and details (processing, completed, failed, etc.) - crypto-network: Get supported blockchain networks with withdraw fees and limits - p2p/trading-pairs: List P2P-specific trading pairs

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.

End-to-end Solana development playbook (Jan 2026). Prefer Solana Foundation framework-kit (@solana/client + @solana/react-hooks) for React/Next.js UI. Prefer @solana/kit for all new client/RPC/transaction code. When legacy dependencies require web3.js, isolate it behind @solana/web3-compat (or @solana/web3.js as a true legacy fallback). Covers wallet-standard-first connection (incl. ConnectorKit), Anchor/Pinocchio programs, Codama-based client generation, LiteSVM/Mollusk/Surfpool testing, and security checklists.

Provides Base network configuration including RPC endpoints, chain IDs, and explorer URLs. Use when connecting wallets, configuring development environments, or setting up Base Mainnet or Sepolia testnet. Covers phrases like "Base RPC URL", "Base chain ID", "connect to Base", "add Base to wallet", "Base Sepolia config", "Base explorer URL", "what network is Base", or "Base testnet setup".
