Prerequisites
Foundry
For this tutorial, we will be using Foundry toolkit to develop, compile, and deploy our contracts. If you do not have Foundry installed, follow the Foundry installation instructions.Setup
First, we need to create a new directory for our project.Implementing the Contract
Before writing our contract, we first need to rename the template contract toNewInitiaERC20.sol
InitiaCustomERC20
contract from the @initia/initia-evm-contracts
package.
src/NewInitiaERC20.sol
InitiaCustomERC20
contract and add the constructor to initialize the contract with the name, symbol, and decimals of our custom ERC20. For this tutorial, we will simply customize the base contract by adding a logic to mint tokens to the contract deployer. during deployment.
src/NewInitiaERC20.sol
forge compile
, we will get an error.
This is because the default Counter.t.sol
expects the original Counter.sol
contract to be available. To fix this, we will rename Counter.t.sol
to NewInitiaERC20.t.sol
.
test/NewInitiaERC20.t.sol
forge compile
should work without any errors.
Deploying the Contract
Now that Our contract is compiled and ready, we can deploy it to the MiniEVM. To accomplish this, we will use Foundry’sforge create
command
cast call
command.
