Practical overview
When it fits
Use Etherflow when you have an Ethereum JSON-RPC endpoint and want to explore a call, troubleshoot its response or prepare a code example.
Who it is for
- Ethereum developers investigating JSON-RPC calls and responses.
- Developers who want sample client-library code from an RPC request.
- Contributors extending the project's front-end library support.
Documented uses
- Send Ethereum JSON-RPC requests without writing request code first.
- Inspect responses while debugging standard RPC methods or supported trace calls.
- Generate sample code for a selected method and library.
- Share a configured request with its endpoint and parameters encoded in the URL.
Requirements & limits
The repository README links to a hosted demo and documents local startup with npm. The project is licensed under MIT.
- You must supply an Ethereum JSON-RPC endpoint; Etherflow is an interface for sending requests, not a node.
- Shared URLs include the endpoint, preferred library, method and parameters.
- The documented trace support is for Parity/OpenEthereum's trace module.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
