EndpointWhale movements, newest first, in one feed: large on-chain transfers (Ethereum, Arbitrum, Base from $1M, stablecoins from $5M; Bitcoin from $1M, change excluded), exchange in- and outflows (exchanges’ own proof-of-reserves addresses), stablecoin mints / burns, bridge transfers, large swaps on the biggest Uniswap v3 / Aerodrome pools (from $500K) and Hyperliquid whale position changes and large Hyperliquid trades (from $1M). Labels only from cited sources; every other wallet is named by its address. USD: stablecoins at their latest fresh Chainlink answer (USDT, USDC, DAI / USD), WBTC at the Hyperliquid BTC mark × Chainlink WBTC / BTC, other assets at the Hyperliquid mark; no fresh price → usd null and priceSource "unavailable" (such items never pass minUsd). priceSource and details.value say which. CEX trade prints are not included.
