# Introduction

Welcome to the Etn-sc Developer docs!

This section includes information for builders. If you are building decentralized apps on top of Etn-sc, head to the dapp-developer docs. If you are developing Etn-sc itself, explore the ETN-SC developer docs.

## Dapp developers <a href="#dapp-developers" id="dapp-developers"></a>

Etn-sc has many features that support dapp developers. There are many built-in tracers implemented in Go or Javascript that allow developers to monitor what is happening in Etn-sc from inside an app, and users can build their own custom tracers too. Etn-sc also includes a suite of tools for interacting with Electroneum smart contracts using Etn-sc functions using Go functions inside Go native applications.

* [Developer mode](/etn-sc-client/developers/dapp-developers/dev-mode.md)
* [Etn-sc in Go apps](/etn-sc-client/developers/dapp-developers/go-api.md)
* [Go contract bindings](/etn-sc-client/developers/dapp-developers/go-contract-bindings.md)
* [Account management in Go apps](/etn-sc-client/developers/dapp-developers/go-account-management.md)

## ETN-SC developers <a href="#geth-developers" id="geth-developers"></a>

Etn-sc developers add/remove features and fix bugs in Etn-sc. The ETN-SC developer section includes contribution guidelines and documentation relating to testing and disclosing vulnerabilities that will help you get started with working on Etn-sc.

* [Code review guidelines](/etn-sc-client/developers/etn-sc-developer/code-review-guidelines.md)
* [Contributing to Etn-sc](/etn-sc-client/developers/contributing.md)
* [Developer guide](/etn-sc-client/developers/etn-sc-developer/developer-guide.md)
* [Disclosures](/etn-sc-client/developers/etn-sc-developer/disclosures.md)
* [DNS discovery setup guide](/etn-sc-client/developers/etn-sc-developer/dns-discovery-setup-guide.md)

## EVM tracing <a href="#evm-tracing" id="evm-tracing"></a>

Tracing allows developers to analyze precisely what the EVM has done or will do given a certain set of commands. This section outlines the various ways tracing can be implemented in Etn-sc.

* [Introduction](/etn-sc-client/developers/evm-tracing/introduction.md)
* [Basic tracers](/etn-sc-client/developers/evm-tracing/basic-traces.md)
* [Built-in tracers](/etn-sc-client/developers/evm-tracing/built-in-tracers.md)
* [Custom tracers](/etn-sc-client/developers/evm-tracing/custom-evm-tracer.md)
* [Javascript tracing tutorial](/etn-sc-client/developers/evm-tracing/tutorial-for-javascript-tracing.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developer.electroneum.com/etn-sc-client/developers/introduction.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
