2,100 BTC and 37,060 ETH were transferred from BlackRock ($BLK) wallets

BlackRock-linked ETF wallets transferred 2,100 BTC and 30,760 ETH to Coinbase Prime within an hour on the night of the 13th, according to Onchain Lens, with the BTC valued at about $145.38 million and the ETH at about $60.21 million for a combined $205.59 million. The move represents roughly 0.27% of BlackRock's on-chain BTC holdings of about 787,100 coins and 1.08% of its roughly 2.859 million ETH, making the ETH share about four times larger relative to holdings. Coinbase Prime is the exchange's institutional arm, so the transfers may reflect routine custody or liquidity operations rather than directional trades. Watch for follow-on flows from the same wallets and whether the ETH-heavy skew continues.
