Welcome to EASM

Learn how to write secure, high-performance smart contracts using Ethereum Assembly Language.

🚀 Your First Contract

📦 Installation

NPM Installation

$ npm install -g easm-lang
# Verify installation
$ easm --version
Install globally and verify the command line interface

Source Setup

$ git clone https://github.com/easm-lang
$ cd easm-lang
$ npm install
$ npm run build
$ npx easm
Build from source for developers and contributors

✍️ Your First EASM Contract

Create 'greeter.easm'

contract Greeter{
  owner: Address
  message: String

  fn constructor(initMsg: String) {
    owner = @sender
    message = initMsg
  }

  pub fn get() {
    return message
  }
}

Compile and Deploy

$ easm compile greeter.easm
Compiler OK: Wrote greeter.easm.bytecode
$ easm deploy greeter.easm.bytecode
Contract deployed to 0x3fA...
Compile your contract and deploy to Ethereum networks using the CLI tool
