The developer’s foundation of the Telos blockchain is RPC (Remote Procedure Call), which is an essential tool for the developer. It links to the blockchain network and allows for communications with it, like asking for data or completing transactions. However, developers often make common mistakes when they need help with RPC endpoints. Understanding and avoiding these mistakes can save time and prevent errors in your projects.
-
Incorrect Configuration of Telos RPC Endpoints
One of the most common mistakes is misconfiguring the Telos RPC endpoint. A bad URL or port number may be responsible for your app’s inability to sync with the blockchain. Make sure that the endpoint URL is what you intend it to be and also that it matches the network that you aim to interact with, either by main net or the testnet.
Solution
Double-check the RPC endpoint URL and port number. If necessary, refer to official Telos documentation or trusted sources to verify the correct configuration details.
-
Ignoring Rate Limits
Telos RPC endpoints are often designed with rate limits in mind to serve as a safeguard against abuses and fair treatment for API users. Failure to abide by these limitations can result in your requests being throttled or stopped, greatly affecting your application’s performance.
Solution
Be aware of the rate limits that the RPC provider may suggest. Implement exponential backoff or retry mechanisms in your code to handle rate limit responses gracefully.
-
Not Handling Errors Properly
One of the most common errors is the nonexistence of error handlings. Remember to treat errors like timeouts, network failures, or invalid responses. If you do not handle them, your application might crash or behave in unuseful ways.
Solution
Implement extensive error handling at the time of app development. Check for different types of errors and provide meaningful messages or fallback mechanisms to ensure smooth operation even when issues occur.
-
Using Insecure Connections
Security is of utmost importance, hence the reason for interacting with the blockchain networks. Instead of using HTTPS, which provides security, you expose your application to several threats, such as man-in-the-middle attacks, by using HTTP connections that are not secured.
Solution
To ensure the security of your RPC endpoint, always encrypt the data using modern techniques, including HTTPS. This methodology is a great security measure as it effectively guards information against eavesdropping or alteration.
-
Overlooking Version Compatibility
Telos RPC endpoints may have different versions, and using an incompatible version can lead to unexpected behavior or errors. This is particularly important when working with libraries or frameworks that depend on specific RPC versions.
Solution
Ensure that the version of the Telos RPC endpoint you are using is compatible with the tools and libraries in your development environment. Regularly update your dependencies and check for any version-related issues.
-
Failing to Optimize Queries
Such ineffective queries will add to the existing latency issue and cause increased strain on the RPC endpoint, which may negatively impact the entire application’s performance. This really applies when you are combining multiple inputs into a single equation and manipulating large datasets.
Solution
Improve the speed of your requests by loading only the wanted data and avoiding unnecessary requests. Paging large datasets using appropriate mechanisms and caching techniques can also prevent repetitive HTTP requests.
-
Ignoring Documentation and Updates
Neglecting to read the documentation or keep up with updates can result in missing out on essential changes or best practices. This oversight can lead to using deprecated features or missing out on performance improvements.
Solution
Review the official Telos documentation regularly to stay informed about updates and new releases. Join community forums or follow relevant channels to stay updated on best practices and changes in the Telos ecosystem.
Conclusion
Telos RPC requires attention to detail and best practices. Avoid common mistakes like wrong configuration, ignoring rate limits, improper error handling, insecure connections, version compatibility, non-optimized queries, and neglecting docs for smoother development and reliable apps. Stay informed and proactive to make the most of Telos RPC and its powerful capabilities.
