Coinbase Migrates Internal Bitcoin and Ethereum Wallets in Planned Security Refresh

The exchange describes the onchain shift as a routine security measure to limit exposure from long-lived wallet addresses.

Overview

  • Large transfers seen on public ledgers reflect moves between Coinbase-controlled legacy wallets and new exchange addresses, not customer outflows.
  • Trading, deposits and withdrawals continue without interruption, and customer deposit addresses remain unchanged during the process.
  • Coinbase says the rotation was planned in advance and is unrelated to a breach or to market volatility.
  • The company warns of impersonation scams and stresses it will never ask for passwords, 2FA codes or seed phrases.
  • Industry commentary ties more frequent rotations to rising cyber risks such as AI-assisted reconnaissance and long-term quantum threats, and Coinbase will post a blog update when the migration completes.
