How to deploy a token on Arbitrum in 3 steps (with no-code alternative)

In this guide I will show you how to deploy an ARC-20 token on Arbitrum using Smart Contracts with Solidity. In addition, I will provide you with a non-programming option, in case you prefer a simpler solution.

Arbitrum is a second layer (L2) solution over Ethereum that offers fast and cost-effective transactions without sacrificing the security provided by the Ethereum network.

The tokens deployed on Arbitrum use the ERC-20 standard and are compatible with DeFi applications, wallets and exchanges that support the Arbitrum network.

By supporting the Ethereum Virtual Machine (EVM), any smart contract or decentralized application (dApp) created for Ethereum can be easily adapted to run on Arbitrum.

Smart and Solidity: How to Deploy an token

To create an ARC-20 token on Arbitrum, you need to write a smart contract using Solidity, which is the most common language for development on EVM-compatible blockchains like Ethereum and Arbitrum. Here's how to do it step-by-step.

1. Configure your development environment

First, you need to set up a development environment. There are several tools that make it easier to create smart contracts:

• Remix: An online development environment that supports Solidity without the need for additional configuration.
• Hardhat or Truffle: Frameworks that you can install locally to compile, test and deploy contracts. These frameworks can be connected to MetaMask to manage your wallets.

You will also need to connect MetaMask to the Arbitrum network.

2. Write the ERC-20 contract

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyToken is ERC20 {
    constructor(uint256 initialSupply) ERC20("MyToken", "MTK") {
        _mint(msg.sender, initialSupply);
    }
}

Here we are using OpenZeppelin' s ERC-20 implementation to simplify the process. In this example:

• The builder initializes the token name token MyToken) and its symbol (MTK).
• The _mint function creates tokens and assigns them to the contract creator.

Key functions of the ERC-20 standard:

• transfer: allows token holders to send their tokens to another address.
• approve: sets a limit on the number of tokens that a third party can spend on behalf of the holder.
• transferFrom: transfers tokens from one account to another according to a previously established permission.

3. Compile and deploy the contract

Once you have your contract ready, you need to compile it. You can do this from Remix or using command line tools like Truffle or Hardhat. Here is an example of how you could deploy the contract using Truffle:

truffle migrate --network arbitrum

Deploying a contract on Arbitrum ETH Arbitrum) to cover gas fees, which are much lower than on Ethereum to its Layer 2 architecture. The cost of deploying a token Arbitrum range from just a few cents to a few dollars, depending on network congestion.

4. Gas cost optimization

Although gas fees on Arbitrum are considerably lower than on Ethereum, it is still important to write efficient contracts to avoid unnecessary costs. Here are some tips to optimize gas usage:

• Minimizes warehousing operations: storing data in Solidity is expensive. It uses variables of type memory instead of storage when possible.
• Bundle transactions: If you can, make multiple trades in a single transaction to minimize gas commissions.
• Use external libraries: Take advantage of optimized and secure code from libraries such as OpenZeppelin.

5. Testing and safety

Before deploying your token the mainnet, it is essential to conduct thorough testing on a testnet. For Arbitrum, the testnet is Arbitrum . Use tools like Hardhat to simulate the deployment and write unit tests to ensure that the contract complies with the ERC-20 standard.

Common mistakes to avoid:

• Reentrancy attacks: occur when an external function calls the contract again before its execution is finished.
• Overflow and underflow: Newer versions of Solidity (0.8.x) already handle these problems, but in older versions you will need to use SafeMath.

When you are sure that everything is working correctly, deploy first on the testnet before moving on to the mainnet at Arbitrum.

The no-code alternative: Smithii Tools

If you have no programming skills or prefer to avoid the technical complexity, you can use Smithii Tools to create your token on Arbitrum easily and without writing code using the Smithii Token Creator.

How to create a token on Arbitrum using Smithii in 3 steps

1. Enter your token name: Type the name you want for your token.
2. Select the symbol: Choose a symbol of up to 8 characters.
3. Set the total supply: Decide how many tokens will be available, typically between 10 million and 100 billion.

Advanced options

• Airdrop : Prevents your token from token tradable until you activate it.
• bot: Imposes a time limit between transactions to lock bots.
• Anti-whale: Limits the size of transactions to prevent large players from influencing the market too much.

The cost of creating a token Arbitrum Smithii is 0.01 ETH gas fees, one of the lowest rates available.

Contract verification and modification at Arbiscan

Once you've deployed your token, you can add social media links and logos to increase its visibility. If you used Smithii , the contract verification required to add the social media links is done automatically. If not, follow this step-by-step guide to do it manually.

What to do after creating the token on Arbitrum? Launch your Liquidity Pool

After creating your token, we recommend launching a liquidity pool on Uniswap an Arbitrum DEX. This will allow users to trade your token. You can check out our guide on how to do this without any coding.

In the same way, you can implement a VolumeBot for Arbitrum that will allow you to artificially increase the volume and amount of makers of your coin. This way your community will catch the hype and you can attract more investors organically.

Is it safe to use Smithii create a token?

Smithii Tools has been audited by CoinFabrik under the Mantis protocol, which guarantees the security of our products. You can read more in this audit report.

Conclusion

In this article we saw how to deploy an ARC-20 token on Arbitrum using Solidity, and also how to do it non-programmatically using Smithii Tools. Both options are valid, and the no-code alternative simplifies the process by avoiding complex technical steps.
