CREATE YOUR FIRST GRC-20 TOKEN
The body of a GRC-20 token contains the methods and events a GRC-20 token must have.
A GRC-20 token must be able to:
- Transfer tokens from one account to another
- Return the balance of an account
- Return the total tokens available in the token
- Transfer tokens to an account
This is an example of how to create and deploy a simple GRC-20 token on the Gather testnet. You can follow the same steps for the mainnet after changing the configuration from testnet to mainnet.
- 1.Metamask or any web3 wallet configured with Gather testnet.
- 2.Testnet GTHs.
For this guide, we will be using remix as IDE and MetaMask as our wallet.
- 1.
- 2.In contracts create a new file
token.sol
and add the following code there. You can get the code from here as well - https://github.com/GatherNetwork/GRC-20-Token.git// SPDX-License-Identifier: MITpragma solidity ^0.8.3;import "@openzeppelin/contracts/token/ERC20/ERC20.sol";import "@openzeppelin/contracts/access/Ownable.sol";contract Token is ERC20, Ownable {constructor(string memory _name, string memory _symbol, uint256 _initialSupply) payable ERC20(_name, _symbol) {_mint(msg.sender, _initialSupply);}function mint(uint256 amount) public onlyOwner {_mint(msg.sender, amount);}} - 3.Compile
token.sol
- 4.Switch to Gather Testnet Network in your MetaMask.
- 5.In environments of Remix, select injected web3 and connect an account with enough testnet GTHs.
- 6.Fill in the details for the deployment section and deploy your contract.Please note that the unit provided for the field initial supply is in WEI.Eg: For creating 1,000 tokens, for the initial supply you need to enter1,000 * 1,000,000,000,000,000,000 = 1,000,000,000,000,000,000,000In this case, the total number of DEM tokens minted will be 1000000000000 * 1e-18.
- 7.This will open your MetaMask extension and ask you to confirm the pending transaction. Click the Confirm button on the MetaMask popup.
- 8.You have successfully created and deployed a GRC-20 token on the Gather test network. You check your contract details on the gather testnet block explorer.
