Overview

Live whale alerts: the largest recent USDC / WETH / cbBTC / USDT / WBTC transfers on Base or Ethereum, with USD value, from/to wallets, counterparty labels (contract? verified? scam-flagged?), tx hash and age. The smart-money / whale-watching feed trading agents poll to front-run big flows — a Nansen-style whale alert without the subscription. Each whale wallet chains into /crypto/smart-money (what is this wallet doing?) and /crypto/wallet (what does it hold?).
