BlackRock-related addresses transferred a cumulative approximately $444 million in crypto assets to Coinbase Prime.

A wallet linked to BlackRock moved roughly $443.88 million in crypto to Coinbase Prime on November 12, comprising 4,189 BTC worth about $304.72 million and approximately 68,230 ETH valued near $139.16 million, according to OnchainLens. The transfer originated from an address tagged as BlackRock's Coinbase Prime deposit wallet, making it one of the larger single-day inflows tied to the asset manager. Such moves matter because Coinbase Prime serves as the custodian and execution venue for BlackRock's spot bitcoin and ether ETFs, so deposits often precede creation or redemption activity. The scale of the transfer suggests continued institutional-scale positioning in both major tokens rather than a rotation between them. Traders will watch subsequent flows into and out of the same deposit address, along with ETF share creation data, to determine whether the assets are being staged for purchases or moved as part of routine custody rebalancing.
