Does exactly what you'd expect: point it at a wallet address and get back token balances, portfolio values, and holdings across 20+ chains including XLayer, Solana, Ethereum, and Base. The skill handles the annoying parts like format validation between EVM and Solana addresses, automatic chain resolution, and pre-flight binary updates with checksum verification. Particularly solid for pre-swap balance checks or as an entry point before routing to other OKX skills for PnL analysis or trading. The command structure is clean and the multi-chain support actually works without wrestling with different RPC endpoints.
