$139.56M WETH moved onchain – a major liquidity shift on Base.

A single whale address moved $139.56 million in WETH on the Base network in transaction 0x90072621d5cb87efe754ee1a4b30fc6b9f8318392a4ef09a27dfd935c31be63e. The transfer originated from 0xbbbb…ffcb, a wallet showing no mixer interaction, fresh creation, dispersal pattern, sanctions linkage, or bridge usage.

The size alone makes this one of the larger WETH flows on Base in recent memory. When exchange reserves trend lower and a whale moves this volume onchain rather than to a known exchange deposit address, it often signals a custody or cold-storage reorganisation, or a positioning move ahead of an expected leg higher.
