Coinbase ETH theft

Wallet provider compensated for discovering the exploit

According to report made public on Mar. 21, Biggest United States exchange service and digital wallet provider Coinbase has compensated a Dutch company with a $10,000 prize after it uncovered a smart contract glitch enabling users to steal “as much as they want” in Ethereum (ETH).

In January, for instance, there was a report regarding a website malfunction at, which enabled users to pay and request refunds in either Bitcoin or Bitcoin Cash, leading to huge profits for some users. For what it’s worth, Overstock and Coinbase have something in common, and that is their merchant integration API.
