How MemeCoins are created, from a Smart-Contract to the decentralized exchanges.

Memecoins are a trend again, after the huge success of Doge, Shiba, and many others, PEPE took the market's attention after getting to a market cap of more than 700M dollars, and for what reason? being a famous meme. In this article, we will explore the steps required to create a meme coin on Ethereum, including how smart contracts are written, deployed, and how do the coins get to the public.

Step 1: Writing the Smart Contract

The first step in creating a meme coin on Ethereum is to write a smart contract. A smart contract is a self-executing program that runs on the Ethereum blockchain, and it contains the rules and parameters for your meme coin.

The smart contract for a meme coin should include several key elements, including the name of the coin, the symbol, the total supply, and the number of decimal places. It's important that it includes functions that allow users to transfer and mint coins, as well as a function for setting the initial supply of the coin.

To write the smart contract developers use Solidity, a programming language that is specifically designed for creating smart contracts on the Ethereum blockchain. A well know option used to write solidity is Remix IDE, a web-based development environment, to write, test, and debug a smart contract.

Here is an example of a simple smart contract for a meme coin:

pragma solidity ^0.8.0;

contract MemeCoin {
    string public name = "MemeCoin";
    string public symbol = "MEME";
    uint256 public totalSupply = 1000000;
    uint8 public decimals = 18;

    mapping(address => uint256) balances;

    constructor() {
        balances[msg.sender] = totalSupply;
    }

    function balanceOf(address _owner) public view returns (uint256 balance) {
        return balances[_owner];
    }

    function transfer(address _to, uint256 _value) public returns (bool success) {
        require(balances[msg.sender] >= _value);
        require(_to != address(0));
        balances[msg.sender] -= _value;
        balances[_to] += _value;
        emit Transfer(msg.sender, _to, _value);
        return true;
    }

    function mint(address _to, uint256 _amount) public returns (bool) {
        require(_amount > 0);
        require(totalSupply + _amount <= 1000000000);
        totalSupply += _amount;
        balances[_to] += _amount;
        emit Transfer(address(0), _to, _amount);
        return true;
    }

    event Transfer(address indexed _from, address indexed _to, uint256 _value);
}

This smart contract creates a meme coin called MemeCoin with the symbol MEME. It has a total supply of 1,000,000 coins and 18 decimal places. The contract includes functions for transferring coins, checking balances, and minting new coins.

Step 2: Deploying the Smart Contract

Once the smart contract is written and tested, it should be deployed to the Ethereum blockchain. To deploy a smart contract, the required tools are Remix or Truffle.

As for Remix, the steps to deploy the smart contract are:

1. Opening Remix and selecting the "Solidity" tab.
2. Pasting the smart contract code into the text editor.
3. Compiling the smart contract by clicking the "Compile" button.
4. Clicking the "Deploy & Run Transactions" button.
5. Selecting the "Injected Web3" environment.
6. Choosing an account to deploy the contract from.
7. Clicking the "Deploy" button.

Once the smart contract is deployed, the creator receives a transaction hash useful to track the progress of the deployment on the Ethereum blockchain. A blockchain explorer like Etherscan is convenient to view the status of the transaction and check if the contract has been successfully deployed.

Step 3: Adding Liquidity After the smart contract has been deployed

Now to make the coin tradable, the creator of the smart contract should add liquidity to the smart contract. When a liquidity pool is created on a decentralized exchange like Uniswap, users can trade the meme coin with other cryptocurrencies in the pool, such as Ether, which provides liquidity to the market.

A liquidity pool is a smart contract that holds a reserve of two different tokens, which users can trade with each other. Liquidity can be added to a meme coin by creating a liquidity pool on a decentralized exchange (DEX) like Uniswap.

The steps to add liquidity to a meme coin on Uniswap are:

1. Going to the Uniswap website and connecting an Ethereum wallet.
2. Clicking on the "Pool" tab and selecting "Add Liquidity."
3. Choosing the meme coin and the other token to compose a pool with (usually Ether).
4. Entering the amount of both tokens that will be added to the pool.
5. Then Uniswap will automatically calculate the exchange rate and the amount of liquidity tokens that will be received in return.
6. Lastly, confirming the transaction and waiting for it to be processed.

Once the liquidity pool is created, users can buy and sell the meme coin on Uniswap using Ether or other tokens in the pool. The price of the meme coin will be determined by the market demand and supply in the liquidity pool.

Conclusion

Creating a meme coin on Ethereum is a fun and creative way to experiment with blockchain technology. By writing a smart contract, deploying it to the Ethereum blockchain, and adding liquidity to a DEX like Uniswap, you can create a new cryptocurrency that can be traded on the open market. However, it is important to remember that creating a meme coin is not a guarantee of financial success, the purpose of this blog is to spread knowledge on blockchain and blockchain development.

Memecoins are only one of the many use cases for blockchain technology such as NFTs, decentralized applications, and Token Gating.
