About Coinbase program

The cryptocurrency exchange runs a four-tier reward system where the amount of the remuneration depends on the severity of the bug: $200 for a low-impact issue, $2,000 for medium, $15,000 for high, and $50,000 for a critical issue.

“In order to be deemed valid, a report must demonstrate a software vulnerability in a service provided by Coinbase that harms Coinbase or Coinbase customers. Coinbase awards bounties based on the severity of the vulnerability. We determine severity based on two factors: impact and exploitability,” according to the company’s bounty terms.  

Thus, apparently, the revealed vulnerability was classified as something between high and critical.  

Also, last year, the company paid $10,000 for the vulnerability that allowed abusers to transfer unlimited amounts in Ethereum to their wallets.
