  When coding for cryptocurrencies, it's important to avoid hardcoding sensitive information such as private keys or API credentials. Storing these credentials in configuration files or using secure key management solutions is a better approach. Hardcoding sensitive information can expose your application to security risks if the code is ever compromised.

  When working with cryptocurrencies, it's crucial to avoid relying solely on third-party APIs. While APIs can provide convenient access to blockchain data and services, they can also introduce dependencies and potential points of failure. It's important to have backup plans and alternative solutions in case the APIs become unavailable or unreliable.
