Coinbase Shifts Bitcoin and Ethereum as Part of Planned Security Upgrade

TLDR:

• Coinbase begins planned BTC and ETH wallet migration to refresh internal security infrastructure.
• Large onchain transfers will appear as funds move between Coinbase-controlled internal wallets.
• Customer trading, deposits, and withdrawals continue without interruption during the migration.
• Coinbase warns users against impersonation scams attempting to exploit the visible migrations.

Coinbase initiated a major onchain migration of its internal BTC and ETH wallets today as part of a scheduled security upgrade. The exchange said this is a routine process designed to refresh internal infrastructure and reduce long-term exposure of stored funds. 

Coinbase also noted the move is unrelated to market volatility or recent industry events. The company stated that customer access remains unaffected throughout the migration.

Coinbase Starts Onchain Migration for Internal BTC and ETH Wallets

Coinbase confirmed in its transparency update that it is shifting funds from legacy internal wallets to new addresses. The exchange described the effort as part of its standard approach to maintaining institutional-grade protection across its systems. 

Coinbase stated that periodic wallet rotation limits exposure time for stored assets. The announcement emphasized that the project has been planned well in advance by the internal security team.

Large onchain transfers will appear across BTC and ETH networks as older Coinbase-controlled wallets move funds to new ones. Many of the outgoing addresses are already labeled on several blockchain analytics platforms. 

Coinbase stated that customers may see very large movements of funds onchain, but all activity originates from exchange-owned wallets. The update clarified that these transfers should not be interpreted as unusual or reactive behavior.

Coinbase reported that no downtime is expected for any product during the migration window. Trading, deposits, and withdrawals remain fully operational while the internal shift continues. 

The company also confirmed that customer deposit addresses are not part of this migration and will stay unchanged. Users can continue handling assets without adjusting their activity.

Scam Warnings Issued as Onchain Transfers Gain Visibility

The company warned that the visibility of large transactions may attract impersonation attempts. The exchange urged customers to avoid responding to unsolicited calls or messages claiming to represent Coinbase staff. 

The update stated that the exchange will never request passwords, 2FA codes, or seed phrases under any circumstances. The company added that it will not call users to tell them to move funds during the migration.

The exchange cautioned that scammers may attempt to create urgency by referencing the wallet rotation. According to the update, users should disregard any messages asking them to transfer assets to new addresses. 

Coinbase said it will not provide new wallet addresses for customer use. The company encouraged users to remain alert and report suspicious contact attempts.

The exchange said it will update its blog once the internal migration is complete. 

The company described the process as part of its long-term approach to maintaining secure infrastructure. The exchange reiterated that the project is unrelated to market conditions. Coinbase stated that the upgrade reinforces its ongoing security practices.
