# Overview

## What is LaunchSwap Protocol?

LaunchSwap is a novel token protocol based on ERC1155 and inspired by BRC20. It is a combination of **inscription** and **smart contract, also called smart inscription.** 

#### Simple

 It's very easy to deploy a token like BRC20. To deploy a token, you only need a tick(symbol), supply and limit per mint. You don't need to write any code.

#### Smart

LaunchSwap is based on ERC1155 that is multi token standard. ERC1155 can represent any number of fungile and none-fungible token types. The ERC-1155 Multi Token Standard allows for each token ID to represent a new configurable token type, which may have its own metadata, supply and other attributes.

#### Efficient

ERC20 require deployment of separate contracts per token type. But LaunchSwap can deploy any number of token in one contract, thus saving a lot of gas.

#### Fair

LaunchSwap adopts fair launch mode to distribute tokens. 

**The difference between ETHs, BRC20 and** LaunchSwap**.**
