What is Arbitrum?

Arbitrum is a layer 2 scaling solution for Ethereum that enables fast, low-cost transactions. It is an Ethereum Virtual Machine (EVM) compatible chain that allows developers to deploy smart contracts and dApps with ease. Arbitrum uses Optimistic Rollups, a technology that bundles transactions into a single batch and validates them off-chain, reducing congestion on the Ethereum network.

Building on Arbitrum

Building on Arbitrum is straightforward, and the process is similar to building on Ethereum. You will need to set up a development environment, write your smart contracts, and deploy them to the network.

Set up a development environment

To set up a development environment, you will need a few tools:

  • A text editor to write your code. We recommend Visual Studio Code or Sublime Text.
  • Node.js to run your code locally and interact with the network.
  • Truffle, a development framework for Ethereum, to compile and deploy your smart contracts.
  • Ganache, a personal blockchain for Ethereum development, to test your smart contracts locally.

Write your smart contracts

Once you have set up your development environment, you can start writing your smart contracts. Smart contracts are self-executing programs that run on the blockchain and enable dApps to be built. They are written in Solidity, a programming language for Ethereum.

To get started, you can use the OpenZeppelin library, a collection of reusable smart contracts that have been audited for security. The library includes contracts for token standards, access control, and more.

Deploy your smart contracts to Arbitrum

After writing your smart contracts, you can deploy them to the Arbitrum network. To do this, you will need to connect to the network using an RPC endpoint. You can use Infura or Alchemy to connect to Arbitrum.

Once you have connected to the network, you can deploy your smart contracts using Truffle. Truffle will compile your smart contracts, generate the deployment scripts, and deploy them to the network.

Creating Your dApps

Once you have deployed your smart contracts to Arbitrum, you can start building your dApps. dApps are decentralized applications that run on the blockchain and are accessible to anyone with an internet connection.

To build a dApp, you will need to create a user interface that interacts with your smart contracts. You can use frameworks like React, Angular, or Vue.js to build your user interface.

To interact with your smart contracts, you will need to use a library like Web3.js. Web3.js is a collection of libraries that allows you to interact with the Ethereum network from your dApp.


In conclusion, building on Arbitrum and creating your dApps is a straightforward process. With the right tools and knowledge, you can deploy smart contracts to the Arbitrum network and build decentralized applications that are fast, secure, and low-cost.
