$137.49M WETH moved off a Base wallet in the largest tracked move on-chain right now.

A 32-day-old wallet — 0xbbbb…ffcb — pushed $137.49M in WETH off Base in a single transaction. This is not a sleepy address. In under five weeks, it has racked up 19,168 transfers while talking to only 8 distinct peer wallets across Base and Ethereum.

That is a dense, high-frequency web, not a one-off giant.

Where did the funds land? Within the depth we can trace, they did not hit an exchange, a mixer, a bridge, or any sanctioned address. They stayed in self-custody or somewhere in DeFi. For a move this size, the absence of a clear off-ramp or obfuscation hop stands out — it suggests internal repositioning rather than an exit.

Context: WETH exchange flows are leaning toward distribution right now, but this transaction is not part of that. It is a single, deliberate reshuffle from a young, hyperactive wallet with a tight counterparty circle.
