Preparation

In this tutorial, we will transpile the ERC-20 contract from OpenZeppelin.

Preparation

Before we run the program, we will make some adjustments to the ERC-20 file. We will add the events from the IERC-20 interface to our contract. We do this because later in the contract, we want to emit these events. Another thing we will change is to rewrite all functions _msgSender() to msg.sender. We do this because we want to demonstrate how to call msg.sender in ink!.

Running Sol2Ink

Running Sol2Ink is easy. First we need to navigate to the folder where we saved sol2ink and we will call ./sol2ink path, where path is the path to our ERC20 file. The output file will be stored in the newly created folder generated, containing all of the files of the contract. Now we will try to build it!
