Binance Smart Chain (BSC) has emerged as a popular blockchain network, offering advantages such as low fees, fast transaction processing, and compatibility with the Ethereum Virtual Machine (EVM). One of the key features of BSC is the ability to create and deploy your own tokens. This article will provide a comprehensive step-by-step guide on how to create a token on the Binance Smart Chain.
Step-by-step instructions on how to create a Binance Smart Chain token
1. Set up BSC Chain Wallet:
To begin creating your token on BNB Smart Chain, you need to set up a BSC chain wallet. One popular option is MetaMask, a browser extension that allows you to interact with various blockchain networks. Install the MetaMask extension and follow the instructions here to create a new wallet:
To set up your wallet to connect to the QuickNode, navigate to the networks tab and select “Custom RPC.” You will then need to complete the required fields, as illustrated in the image provided, to configure the connection.
With the configuration in place, your wallet is now able to establish a connection with the QuickNode.
2. Obtain BSC Testnet Tokens:
Before deploying your token on the mainnet, it is advisable to test it on the BSC testnet. Testnet tokens hold no real value and allow you to experiment without any financial risks. Visit a BSC faucet website, such as https://faucet.quicknode.com/binance-smart-chain, and follow the instructions to obtain BSC testnet tokens for your wallet.
To receive BNB, you can copy your wallet address from the MetaMask browser extension and paste it into the designated field. Once you’ve done that, BNB will be sent to your wallet. With newly acquired BNB in hand, you can proceed to utilize it as desired.
3. Connect Wallet to BSC Testnet:
Once you have the testnet tokens in your wallet, connect your wallet to the BSC testnet. Open your MetaMask extension, click on the network dropdown, select “Custom RPC,” and enter the BSC testnet’s URL: https://data-seed-prebsc-1-s1.binance.org:8545.
4. Create a Smart Contract for Your Token:
To create your token, you need to develop a smart contract. Solidity is the most commonly used programming language for smart contracts. Open the Remix IDE (https://remix.ethereum.org/) and create a new file named “YourTokenName.sol.” Write the Solidity code for your token, including necessary functions such as token name, symbol, total supply, and transfer functions.
You can write the provided code in a new file as follows:
// contracts/BEP20.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import “@openzeppelin/contracts/token/ERC20/ERC20.sol”;
contract BEP20 is ERC20 {
constructor(uint256 initialSupply) ERC20(“BEP20Test”, “BPT”) {
_mint(msg.sender, initialSupply);
}
}
Explanation of the code:
- Line 1/2: These lines indicate the license and the desired location of the file.
- Line 3: The solidity compiler is set to version 0.8.0.
- Line 5: The ERC20 package from OpenZepplin is imported, allowing us to utilize its specifications to implement the new token. This standard ensures easy integration with other wallets and programs.
- Line 7: A new contract is defined. You have the flexibility to rename “BEP20” to any desired name, while the “ERC20” part signifies the intention to utilize the ERC20 package imported in line 5.
- Line 8: The constructor function is called when the contract is deployed onto the BSC Testnet. It takes a single parameter, “initialSupply,” of type uint256. Within the constructor, we use the ERC20 functionality imported from OpenZepplin. This functionality requires two parameters: the name of the token (“BEP20Test” in this case) and its ticker symbol (“BPT”).
- Line 9: The “_mint” function, implemented in the ERC20 contract, is called. It creates the token and sends all the newly minted tokens to the “msg.sender,” who is the one deploying the contract onto the testnet. In this case, it will create the specified number of tokens based on the value passed to the “initialSupply” parameter.
Note: The “initialSupply” parameter represents the token amount in WEI format, which is 1e-18. For example, to create 100 tokens, the function should be called with the value 100000000000000000000.
You can also use OpenZeppelin’s ERC20 contract as a starting point.
5. Deploy & Test on Testnet:
Compile your smart contract in Remix and ensure there are no errors.
Once you have successfully compiled the contract, you are now prepared for deployment. Proceed to the “Deploy & Run Transactions” tab in Remix and switch the “Environment” tab to “Injected Web 3.” If you haven’t connected Remix with MetaMask previously, it may prompt you for confirmation.
After establishing the connection between MetaMask and Remix, you will find your wallet address displayed in the “Account” field. At this point, you can select the BEP20 contract from the dropdown menu. You will notice an orange “deploy” button and a corresponding form on the right side. This is where you can provide the argument for the earlier defined “initialSupply” parameter.
To create 100 tokens, enter the value “100000000000000000000” and proceed by clicking “Deploy.” Please note that you will be required to approve the MetaMask transaction, as deploying something onto the network incurs a cost in BNB.
If all the preceding steps have been executed correctly, you should receive a success message in the terminal, indicating a successful deployment.
To access the contract address, navigate to the “Deployed Contracts” tab and copy the provided contract address. You can then visit the bscscan website and search for the contract using the copied address. Upon inspection, you will observe your wallet address in the “from” field, along with the confirmation that 100 BPT tokens have been sent to your wallet.
6. Adding the Token to your Wallet
To view the newly created token in your MetaMask user interface, follow these steps:
- Click on the “Add Token” option located under the “Assets” tab in MetaMask. This action will direct you to a menu containing three fields.
- Paste the Contract address obtained from Remix into the designated field. As you do so, you will notice that all the fields automatically populate with the relevant information of the token.
- Verify that the populated information is correct and matches the details of your token. Once you have confirmed the accuracy, proceed by accepting the token.
By the end of this process, you should be able to see the token listed in your MetaMask wallet, along with its associated details.
