Coinbase has announced a scheduled migration of its internal BTC and ETH wallets to enhance security architecture. This routine operation is not prompted by any security incidents or market fluctuations. The migration will involve significant on-chain fund transfers but will not affect the normal operation of platform products, and user deposit and withdrawal addresses will remain unchanged. Coinbase advises users to be cautious of scams impersonating official personnel and to avoid sharing passwords, verification codes, or private key information.
