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.

Each whale wallet chains into /crypto/smart-money (what is this wallet doing?) and /crypto/wallet (what does it hold?).
