# 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.

## 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.
