Step 5 - Deploy your first contract / Launch your own token
This tutorial is based on the description provided by QuickNode. You can find the original tutorial here. The video is made by Simple Crypto.
Set up MetaMask and get BTC on Botanix testnet
To get started, you will need the Metamask browser extension to create an EVM wallet and some test Bitcoin, which you can get by following the steps laid out in Step 2 - Get test funds.
Implement contract
Head over to the Ethereum Remix IDE and make a new Solidity file, for example Botanix-token.sol
. Paste the following code into your new Solidity script:
Replace the following values:
Line 62: symbol = "QKC"; Choose your own symbol
Line 63: name = "QuikNode Coin"; Choose your own name
Line 64: decimals = 2; set the decimal (value in which tokens can be divided, 0 to 8 decimal units can be used) and establish a total supply value as you wish
Line 65 _totalSupply = 100000; Choose a total supply
Line 66: balances[YOUR_METAMASK_WALLET_ADDRESS] = _totalSupply; Please change YOUR_METAMASK_WALLET_ADDRESS to your own wallet address (This one can be found in your MetaMask interface)
Line 67: emit Transfer(address(0), YOUR_METAMASK_WALLET_ADDRESS, _totalSupply);
Note: The total supply value must have additional trailing zeros as specified by the decimals field. For example, the decimals value in this contract is 2 and we need a total supply of 1000 tokens, so we’ll have to set the total supply variable to 100000 (simply because it won’t allow a decimal point).
Compile the smart contract. Make sure you select the right compiler based on the chosen Solidity version.
Deploy it using injected Web3 (make sure to select Botanix testnet on MetaMask before compiling the contract) and select the right contract to be deployed. Approve the transaction from MetaMask.
Note: We need to deploy the main token contract, select the name of the contract appropriately under the contracts section before deploying the contract (BotanixTestToken here).
If you receive an error message before deployment “This contract may be abstract”, make sure to select the appropriate contract under the Contract tab. Confirm the transaction in Metamask.
That’s it! your token contract is now deployed on Bitcoin’s Botanix testnet!
Get token in MetaMask
To get the token in Metamask, go to the “Deployed Contracts” section in Remix and copy the deployed contract’s address using the copy button near the contract’s name.
Open Metamask, go to the Token tab and click on the Import Tokens button. Paste the contract’s address in the first field. Metamask will fetch the Token Symbol and decimals automatically.
