Coinbase lost approximately $300,000 during the interaction with the "exchanger" contract of the 0x project.

Golden Finance reported that security researchers stated that Coinbase lost approximately $300,000 in accumulated Token fees due to a configuration error in the interaction with the 0x project's swap contract. User "deeberiroz" on platform X (a security researcher from Venn Network) reported on Wednesday that Coinbase interacted with a "swapper" smart contract of the decentralized peer-to-peer exchange 0x, which was not originally intended for Token authorization. The "exchanger" provided by the 0x project is a contract used for executing swap operations. This contract does not require permission, and anyone can call it to perform any operation without ownership restrictions. However, it is not designed to authorize the receipt of tokens, as doing so may expose the funds to risk. The researcher stated that this setup had previously caused known issues related to the airdrop claims of Zora on the Base Layer 2 network.
