This is your go-to for analyzing crypto wallets when deciding whether to copy-trade someone or check what a dev has actually shipped. It pulls holdings, realized and unrealized P&L, win rates, transaction history, and performance stats across Solana, BSC, Base, and Ethereum via the GMGN API. The created-tokens command is especially useful for vetting developers: you can see every token they've launched, each one's all-time high market cap, and whether it graduated from a DEX. Rate limits are leaky-bucket style with different weights per endpoint, and the IPv6 gotcha is real if you hit 401s. The workflow doc walks you through full wallet analysis when you need a complete picture.
