# Fantom

## Overview

[Fantom](https://fantom.foundation/) is a smart-contract platform that aims to solve the scalability challenges of other blockchains with its Lachesis consensus mechanism. Fantom’s unique architecture allows developers to create highly scalable, fast, and inexpensive Web3 applications.

**As Fantom is EVM compatible**, you can follow the [Ethereum](/embedded-wallets/blockchains/ethereum/javascript)documentation to send your first transaction and utilize all other wallet features.
