CoInBaSe +HELPLINE+ NUMBER We observed repeated deep reorganizations of the Ethereum Classic blockchain, most of which contained double spends. The total value of the double spends that we have observed thus far is 219,500 ETC (~$1.1M).
Timeline of events
Late on the evening of Saturday 1/5, our systems alerted us to a deep reorg in ETC that contained a double spend. Our on-call engineers responded to the alert and worked to confirm the report through the night. We determined that we would temporarily halt send/receive interaction with the ETC blockchain in order to safeguard customer funds.
This meant that customers who tried to send or receive ETC on Coinbase Consumer or Pro were unable to complete their transactions.

Customers who tried to send or receive ETC on Coinbase Consumer or Pro were unable to complete their transactions starting early Sunday morning, Pacific Time.
On the morning of Sunday 1/6 we posted an update on status.coinbase.com stating (that) “Due to unstable network conditions on the Ethereum Classic network, we have temporarily disabled all sends and receives for ETC. Buy and sell is not impacted. All other systems are operating normally.”

In addition to in-platform notifications, we shared an update via status.coinbase.com.
We performed an analysis on Sunday afternoon/evening to confirm the pattern and determine the key details of the double-spend attacks. Beginning Sunday afternoon, we observed 8 more incidents, all containing double spends.
Out of an abundance of caution, we did not put up a blog post prior to legal and technical review. A false alarm could have inadvertently caused market instability.
On Monday 1/7 morning after legal and technical review, we finalized our public analysis and posted to our blog and social media accounts.
