Use this skill whenever the user asks about: crypto wallet balances, portfolio values, token holdings or positions, DeFi positions (staking, lending, LP), wallet PnL (profit and loss), transaction history, token/fungible asset prices or charts, NFT holdings or NFT portfolio value, or any web3 wallet analytics. Triggers on mentions of wallet addresses (0x...), ENS names, token names/symbols, "portfolio", "positions", "PnL", "transactions", "balance", "holdings", "NFTs", or any crypto/DeFi analytics queries. Also use when building artifacts or dashboards that display wallet or token data.
