This repository contains the smart contracts for ZetaChain. The smart contracts are written in Solidity, and the repository includes scripts to compile the contracts and generate Go bindings.

As a dApp developer, you can install the protocol contracts package into your project:

yarn add --dev @zetachain/protocol-contracts

Importing ZetaInterfaces and ZetaInteractor for cross-chain messaging:

import "@zetachain/protocol-contracts/contracts/evm/interfaces/ZetaInterfaces.sol";
import "@zetachain/protocol-contracts/contracts/evm/tools/ZetaInteractor.sol";

Importing ZRC20 and the system contract for omni-chain smart contracts:

import "@zetachain/protocol-contracts/contracts/zevm/interfaces/IZRC20.sol";
import "@zetachain/protocol-contracts/contracts/zevm/interfaces/zContract.sol";
import "@zetachain/protocol-contracts/contracts/zevm/SystemContract.sol";

Before you can contribute to this project, you must have the following installed:

• Node.js
• Yarn
• jq
• abigen

To get started with this project, you should first clone the repository:

git clone https://github.com/zeta-chain/protocol-contracts

Once you have cloned the repository, you can navigate to the project directory and run the following command to install the project dependencies:

yarn

To compile the contracts, run the following command:

yarn compile

This will compile the Solidity contracts and output the resulting JSON artifacts to the artifacts directory.

To generate Go bindings for the Solidity contracts, run the following command:

yarn generate

This will use abigen to generate Go bindings for the contracts and output the resulting Go files to the pkg directory.
