$336.86M in WBTC just moved off a 30-day-old wallet — the single largest tracked on-chain transfer right now.

The wallet, 0xbbbb…ffcb, sent the funds in one shot on Ethereum. It’s a young address — first activity only a month ago — but it’s been busy: over 16,000 transfers across Ethereum and Base, dealing predominantly in WETH alongside a 24% stablecoin mix.

Only eight distinct peers have ever touched this wallet, suggesting a tight, deliberate operational footprint rather than random DeFi farming.

The trace stayed clean. Within the depth we can see, the $336.86M did not touch an exchange, mixer, bridge, or sanctioned address — it remains in what appears to be self-custody or a DeFi position.

That matters because WBTC exchange flows over the last 24 hours lean heavily toward distribution: $20.22M in versus just $2.63M out across 130 transfers. A deep-liquidity asset seeing net inflows to venues while a single whale shifts a massive chunk off a private wallet is a supply split worth watching — one side may be preparing to sell, the other is pulling weight into cold storage or a protocol deployment.
