Updated: Deprecation of the Insecure Hedera Consensus Service (HCS) Mirror Node Endpoints
Hedera continues to enhance security by deprecating insecure HCS mirror node endpoints. An updated timeline has been released, detailing key dates for brownout periods and the final shutdown. Users should migrate promptly to secure endpoints to ensure uninterrupted service. Review the full updated schedule and migration details now.
Estimate Gas Dynamically: Best Practices for Smart Contract Development
Learn why hardcoded gas limits are fragile, how to use dynamic estimation with common EVM tools, practical tips like adding buffers and retry logic, and specific guidance for developers using both JSON-RPC and HAPI.
Local, Self-Hosted, or Third-Party? Selecting a JSON RPC Relay for Your Project
When developing smart contracts on Hedera, choosing the right JSON RPC relay setup significantly impacts your workflow, testing speed, and scalability. Should you use a Hedera Local Node for rapid isolated tests, run your own relay for maximum flexibility, or opt for a managed third-party provider to simplify infrastructure management? Each approach has unique strengths suited to different project stages and requirements—let’s explore how you can strategically select the best JSON RPC relay for your application.
How Hedera Ensures Quality in Releases of the Hiero Consensus Node
Hedera’s structured release process and multi-layered testing approach ensure that each code change is thoroughly vetted. New features to the Hiero Consensus Node codebase must pass through successive stages of validation before they are considered “production-ready.”
