The Arbitrum Bridge Beginner’s Guide

5 Mins read

On the Ethereum blockchain, an increasing number of diverse applications have prompted the urgent need to address many common problems. The Ethereum blockchain continues to host a growing number and variety of applications, which causes network congestion. Imagine that thousands of users are using smart contracts to send transactions to the Ethereum blockchain for verification. How does a tutorial on Arbitrum bridges relate to Ethereum network congestion?

What is Arbitrum Bridge?

The Arbitrum project is a public, decentralized, and self-ruling platform that lets you create and trade virtual currency. Arbitrum is a layer-2 solution project designed to enhance Ethereum smart contracts in terms of speed scalability while adding additional privacy features to boot. The platform is designed to make it easy for developers to execute unmodified Ethereum Virtual Machine (EVM) contracts and Ethereum transactions at layer two while benefiting from Ethereum’s excellent layer-1 security. Arbitrum was created to address some of the shortcomings of current Ethereum-based smart contracts. As for the drawbacks, such as long transactions and high execution costs.

How Arbitrum works

Arbitrum uses a type of technology known as an optimistic roll-up which allows smart contracts from Ethereum to scale by sending messages between smart contracts and those in the Arbitrum second chain layer. At layer 2, the vast bulk of processing transactions will be finished, and Arbitrum will record the outcomes in the main chain.

 This methodology can substantially increase the system’s operational speed and relevance. Any validator can subsequently post a rollup block and validate the legitimacy of another block. The process of reassembling an entire chain history from optimised logs using public information is known as a “rollup” and is described by the term. The protocol makes sure the code will execute correctly. The AnyTrust channel and sidechain are two new modes that the Arbitrum project will incorporate in later iterations. The Arbitrum chain allows for individual node inclusion, like many other blockchains. Layer-1 transactions are blended with the assistance of validator nodes that monitor the chain’s state and full nodes.

While other user transaction fees are distributed to other network participants, such as validators, aggregators that send transactions to the layer-1 chain are rewarded in ETH. Other validators check the block’s accuracy and issue a “challenge” if they think it is false as part of the layer-2 solution project’s challenging step for block rollup. If the challenge is invalidated or the block is found to be incorrect, the assets of the dishonest validator will be seized. This procedure ensures that every validator always plays by the rules and takes responsibility for their actions. The Arbitrum Virtual Machine, a custom virtual machine, is also available on the platform (AVM). The Arbitrum Virtual Machine (AVM) sits atop EthBridge and serves as the execution hub for intelligent contracts.

   i. Steps for using the token bridge

  • Make sure you have a crypto wallet such as MetaMask, or any other wallet. Load the wallet with the necessary amount of ETH on the Ethereum main blockchain you want to transfer to a layer two solution through the token bridge.
  •  You need to add the ‘Arbitrum One’ network before offloading to the layer two solutions. 
  •  Choose the Arbitrum network in the drop-down menu, associated with the “Chain’s logo’ and carry out all tasks under the flow, starting with MetaMask, then moving towards Approve and adopting the Switch Network instructions.
  •  Upon switching networks, you can notice the Arbitrum Bridge Metamask logo on top of the wallet. 
  •  You have successfully set the Arbitrum One scalability platform and integrated it with a wallet. Access the website “” for connecting token assets and ensure that you have the wallet attached to the Ethereum mainnet. 

  ii. How Can You Bridge the Tokens?

  •  Open Arbitrum and locate the “L1” field, where you can enter details regarding the amount of ETH/tokens users want to transfer to an L2 solution. Click on “Deposit,” followed by submitting your transaction. 
  •  On the next page, the transaction would move to Arbitrum according to the network traffic. The transfer duration can vary from ten minutes to an hour based on network traffic. 
  •  Users must also ensure seamless connectivity between the Metamask wallet and the Arbitrum One network. It ensures that the fast Arbitrum bridge does not keep you in the dark about the arrival of your funds. You can rely on your crypto wallet to monitor and track ETH token transfers to layer two networks.

  iii. Can You Buy an Arbitrum Token?

The creators of Arbitrum don’t have any immediate plans to launch a native Arbitrum token. Simply put, the company that created Arbitrum didn’t want to make another pass and permitted the use of any cryptocurrency based on Ethereum. As a result, you should be wary of any Arbitrum exchange airdrop schemes that could be a cover for fraud.

 iv. Examples of Projects on Arbitrum

The best Arbitrum bridge projects and applications may provide additional insight into the tool. Several notable projects, including Curve, Sushiswap, Synapse, Abracadabra, and AnySwap, use Arbitrum. Uniswap recently asked governance token owners if they would support the DEX to Arbitrum One.

Advantages of Arbitrum

 i. Low price 

Arbitrum is not only intended to boost Ethereum transaction throughput as a layer-2 scaling solution. However, it also keeps transaction costs to a minimum simultaneously. With the help of this incredibly effective roll-up technology, Arbitrum can significantly reduce costs. 

Although transaction costs are lower, the project still offers validators enough incentives.

  ii. Solid toolkit

To reduce bottlenecks when developing a layer-2 solution, the project team has explored a variety of approaches. As a result, they have created thorough developer documentation for Arbitrum, and programmers can now use tools already available on Ethereum. Nothing particular to this project, like a plugin or a compiler like Hardhat or Truffle, is required for developers to download.

 iii. Decentralised ecosystem

This result depicts alliances with numerous Ethereum infrastructure projects and decentralised applications (DApps), including Uniswap, DODO, Sushiswap, and many others.

Disadvantages of Arbitrum

      i. High Transaction Fees

Transaction fees are the fundamental problem in blockchain networks that Arbitrum seeks to address. What process does Arbitrum use to determine transaction fees? The execution costs for various transactions on the Arbitrum network are tracked by Arbitrum using ArbGas. It’s also crucial to remember that every instruction in the Arbitrum virtual machine requires an ArbGas cost.

    ii. There’s no arbitrum token.

The company that created Arbitrum, Off-chain Labs, does not have a native token for the platform. The creators of Arbitrum also don’t have any immediate plans to launch a native Arbitrum token. Simply put, the company that created Arbitrum didn’t want to make another pass and permitted the use of any cryptocurrency based on Ethereum.


Entering a trade may initially seem intimidating due to the high fees and several steps taken to verify an account. Early L1s like Ethereum and Bitcoin prioritised security and decentralisation over scalability. However, by implementing Optimistic Roll Ups that meet all three criteria, Arbitrum hopes to resolve this blockchain trilemma. The Ethereum community may think that instituting zk-Rollup will provide a more long-term, comprehensive solution. Since Arbitrum is the most advanced L2 platform, it is hoped that it will continue to use the most recent new technologies to scale the platform and encourage its growth.
