Risk warning
OKC is an open-source, open decentralized public chain, and anyone can freely deploy projects. From the principle of blockchain technology, OKX cannot control the quality of any project on OKC, nor will it endorse and be responsible for any project.
There are certain risks in using any project on a decentralized public chain. Users need to identify the quality of the project themselves and be responsible for their own choices so as not to cause financial losses.
Before participating in any project on OKC, you need to know:
1. Before using any project on OKC, please confirm that you have understood all the designs behind it and are willing to take its risks;
2. All users and developers can participate in OKC’s mainnet and testnet for free, and OKC will not charge any fees;
3. Please make sure to distinguish between the OKC test environment and the main network environment. All assets in the test environment have no value. Beware of counterfeit currency fraud;
4. In the process of using any OKC chain project, you must manage your private key, do not disclose your private key to anyone, and be careful to authorize third-party projects.
