Posting on X, Xu said anyone who could provide “conclusive evidence that the OKX Wallet has a backdoor” would receive the reward of 10 bitcoins. “We encourage the tens of millions of OKX Wallet users worldwide to supervise,” he added.
Open source
Xu noted that the wallet’s private key module and all related smart contracts are open source and available for testing on Github.
“Numerous companies across the industry, including competitors, rely on our open-source code. This reflects OKX's long-standing commitment to transparency, security, and open standards.
Non–private-key modules are not open-sourced, as they contain proprietary commercial components. Users are free to evaluate their needs and decide whether OKX Wallet is the right choice for them," Xu added.
Feedback request
Xu said that the OKX Wallet was one of the earliest MPC no-private-key wallets. OKX has since launched a next-generation no-private-key wallet called the CeDeFi Wallet. “We welcome everyone to try it out and provide feedback”, he said, pointing to the open-source code repository of https://github.com/okx
The crypto exchange operator was founded by entrepreneur Xu in 2017 as a subsidiary of the OK Group and was originally known as OKEx before rebranding as OKX in January 2022. Beyond the exchange, it has expanded into blockchain, Web3 services and a native blockchain called X Layer.
