The Merge refers to the Ethereum network’s change of consensus mechanism from Proof-of-Work (POW) to Proof-of-Stake (POS). Check out our latest blog post.
Coinbase Prime will temporarily pause deposits, withdrawals, and transfers for Ethereum and ERC tokens during the Merge (on or around 9/14). ETH and ERC-20 token transactions will be available as soon as possible after ensuring the transition has been successfully reflected by our systems. We expect this could last several hours; however, it could also extend depending on network conditions. The best way to stay on top of the current status is via Twitter and the Exchange status page.
