How to Launch Dapps on Arbitrum? A Complete Guide

Find out how to run your decentralized applications on the Arbitrum protocol – with all the benefits that come with it

Building your dapps on the Arbitrum blockchain may grant better speed, scalability, and even privacy. But how do you do that? This article will guide you through launching dapps on this Ethereum Layer-2 protocol. Let’s get started!

What is Arbitrum?

Built to ​overcome some of the deficiencies of Ethereum-based smart contracts, Arbitrum is a layer-2 scaling solution for the leading blockchain. It facilitates the validation of smart contracts, preventing the Ethereum mainnet from clogging.

The layer-2 was also a top performer during this year’s crypto bear market and is particularly popular amongst DeFi developers.

“When we look at the Arbitrum transactions count, we can see that it has been in an ascendent trend since the beginning of the year, and it has increased 54.7% from August to September.”

Measuring the Impact of Ethereum’s Merge on Layer-2

What are Arbitrum’s benefits for dapp developers?

Among so many Ethereum scalability solutions, Arbitrum has stood out in the second and third quarters of 2022.

Some of the most used dapps in the industry have integrated with the layer-2 throughout the year, which can be explained due to Arbitrum’s benefits for dapp developers. Including:

• Security;
• Implementation ease;
• Superior performance;
• Fraud-proof mechanism.

Also, because Arbitrum is Ethereum Virtual Machine compatible, any developer can build their dapps within the Arbitrum mainnet without having to learn a new coding language – apart from Solidity.

Top Arbitrum dapps

Some of the most popular DeFi dapps on Arbitrum include SushiSwap, Uniswap, GMX, and Stargate. Regarding NFT dapps on Arbitrum, OpenSea, Stratos, and tofuNFT rank at the top.

They have contributed to making Arbitrum hit $1 billion in total value locked (TVL) in September 2022, a 36% increase from the previous quarter.

How to launch dapps on Arbitrum: Step-by-step

Whether you’re developing a brand new dapp or have it done and want to move it over from Ethereum, the process is very simple and open source. Follow the steps below.

Step 1: Compile your Solidity contracts

Assuming that your dapp contracts are already written in Solidity, all you need to do next is to format them for Arbitrum. This is done through the Arbitrum compiler, creating an Arbitrum Virtual Machine (VM).

In order to deploy your contracts onto an Arbitrum chain, you can use any Ethereum development framework, such as Truffle, Hardhat, Foundry, and Brownie.

Step 2: Define the validators to track your VM’s execution

Then it’s time to identify your dapp validators to make sure its VM’s execution is correct. It’s important to note that the layer-2 also provides an AnyTrust Guarantee for its developers so that validation runs smoothly as long as one of them is online and acting honestly.

Step 3: Communicate with EthBridge

The final step to your dapp’s migration to Arbitrum involves making a call to EthBridge to communicate your VM’s launch on Arbitrum and its validators. This smart contract will connect Arbitrum to Ethereum, allowing your dapp to send and receive Ether or any other Ethereum-based tokens to your VM.

At this stage, people using your dapp get to launch your front-end interface in their browsers – that will be interacting with your VM and messaging your validators. Welcome to Arbitrum!
