Opensea warns API users of third-party security breach
Nonfungible token (NFT) marketplace OpenSea has warned users that one of its third-party vendors has experienced a security incident, potentially exposing users’ OpenSea API keys.

“However, your key could be used by external parties which will use its allocated rate limit,” OpenSea explained.
An application programming interface (API) key is code used to identify an application or user and is used for authentication in computer applications. According to OpenSea, its API helps developers build experiences using NFTs and its marketplace data.
The NFT firm called on its users to deprecate their existing key immediately and replace it with a newly generated key which will have the same permissions and rate limits as the existing keys.
Existing keys will expire on Oct. 2, OpenSea confirmed.
OpenSea didn’t disclose how many users were impacted by the security breach and what other information may have been collected.
On Sept. 20, blockchain analytics firm Nansen disclosed a similar breach, which resulted in users losing emails, passwords and blockchain addresses.

Nansen said only 6.8% of its users were impacted across the first 48 hours of the security breach.
The two security breaches prompted some members of the community to ponder whether the incidents are linked.

U.S. Bitcoin Corp, Arrington Capital, Proof Group, Steven Kokinos and Ravi Kaza will provide the capital, management team, and technology required to help get the new company off the ground, which will be carried out in accordance with Celsius’ Chapter 11 bankruptcy plan.
Arrington — who also founded TechCrunch — didn’t disclose exactly why he decided to depart, but admitted a few disagreements ultimately pushed him to remove himself from the board of directors.
“I disagree with some of the decisions made around board constitution and, in particular, the board observers. Because of this, I chose to remove myself from the board of directors.”
The Arrington Capital founder said he’s still looking to support Celsius creditors and shareholders from its bankruptcy proceeding in other ways.
“Apart from not joining the board of directors, our investment and active advisory role via Fahrenheit will go on as planned.”
