# Non-standard Ethereum: Tracing

## Debug API & Trace Module <a href="#debug-api-trace-module" id="debug-api-trace-module"></a>

### Introduction <a href="#introduction" id="introduction"></a>

Geth's [debug](https://geth.ethereum.org/docs/interacting-with-geth/rpc/ns-debug) and [txpool](https://geth.ethereum.org/docs/interacting-with-geth/rpc/ns-txpool) APIs and OpenEthereum's [trace](https://openethereum.github.io/JSONRPC-trace-module) module provide non-standard RPC methods for deeper insight into transaction processing. Some of these non-standard RPC methods are supported as part of Phron's goal of providing a seamless Ethereum experience for developers. Supporting these RPC methods is an essential milestone because many projects like [The Graph](https://thegraph.com/) rely on them to index blockchain data.

This guide will cover the supported RPC methods available on Phron and how to invoke them using curl commands against a tracing node with the debug, txpool, and tracing flags enabled. You can access a tracing node in one of two ways: through a supported tracing RPC provider or by spinning up a tracing node of your own.

To view a list of tracing RPC providers, please check out the Network Endpoints page.
