BlackRock ETF wallet moves more than $271 million in BTC and ETH to Coinbase Prime

A separate on-chain report later identified another July 28 transfer of about $10.07 million in Bitcoin and Ether from a BlackRock-linked ETF wallet to Coinbase Prime, underscoring continued but still ambiguous routing activity.

Fact Check
The specific assessable claim in the content — a separate July 28 transfer of about $10.07 million in BTC and ETH from a BlackRock-linked ETF wallet to Coinbase Prime — is directly and precisely confirmed by OnchainLens (dated 2026-07-28): 158.57 BTC (~$10.06M) plus 4.49 ETH (~$8,500) from IBIT and ETHB wallets, and corroborated by BlockBeats flash 358485. This event is factually accurate. However, the article's $271M headline transfer (2,019 BTC + 29,928 ETH) is verifiably dated December 22, 2025 by both the cited primary monitor Lookonchain and Whale Alert, meaning the coincu piece (published July 27, 2026) recycles an older on-chain event. The July 28 ~$10.07M transfer stands as true; the bundled $271M framing carries a date mismatch.
Summary

A BlackRock-linked ETF wallet transferred more than $271 million in Bitcoin and Ethereum to Coinbase Prime on July 28, according to on-chain monitoring reports including Onchain Lens and Lookonchain, and a separate later report identified another smaller transfer the same day worth about $10.07 million. The newer smaller move was reported as 158.57 BTC worth about $10.06 million and 4.49 ETH worth about $8,500 sent to a Coinbase Prime wallet. Earlier monitoring updates on the larger transfer cited slightly different token counts, including 3,310 BTC and about 28,370 ETH in one report, but consistently described a dual-asset move of roughly $271 million to Coinbase Prime. Because Coinbase Prime is an institutional crypto custody and execution platform used by U.S. spot ETF issuers, such transfers can be associated with custody changes, creations, redemptions, portfolio rebalancing, or execution activity, but the on-chain movements alone do not establish intent. No direct statement from BlackRock or Coinbase was attached to the transfers.
