plugin created with the purpose of efficiently integrating openzeppelin defender modules with hardhat
yarn add --dev hardhat-openzeppelin-defender
or
npm install --save hardhat-openzeppelin-defender
Import the plugin in your hardhat.config.js
:
require("hardhat-openzeppelin-defender");
Or if you are using TypeScript, in your hardhat.config.ts
:
import "hardhat-openzeppelin-defender";
put the administration credentials of your openzeppelin defender OpenzeppelinDefenderCredential
module.exports = {
OpenzeppelinDefenderCredential: {
apiKey: API_KEY,
apiSecret: API_SECRETE,
}
};
This plugin extends the Hardhat Runtime Environment by adding an OpenzeppelinDefender
which contains all the modules of openzepelin defender
import { OpenzeppelinDefender } from "hardhat";
main samples repository
check and get the name of the network by its chainId
OpenzeppelinDefender.Utils.fromChainId(97) // bsctest
extract the abi in string format from the contract interface
OpenzeppelinDefender.Utils.AbiJsonString(abiInterface)
extracts the parameters of a function or event by using its abiInterface
abiInterface : smart contract interface
name : name of the event or function to which the parameters will be extracted
type : specifies whether the extraction of parameters will be from a function or an event
interface AbiInterfaceParams {
abiInterface: Interface;
name: string;
type: "function" | "event";
}
//response
interface AbiInterfaceParamsResponse {
name: string;
signature: eventSignature | functionSignature;
inputs: any[];
fragment: string;
}
example
get the AbiInterfaceParams from the Transfer event of an ERC721 token
const params= {
abiInterface: abiInterface,
name: "Transfer",
type: "event",
};
const result = OpenzeppelinDefender.Utils.getAbiInterfaceParams(params);
//response
/*{
name: 'Transfer',
signature: { eventSignature: 'Transfer(address,address,uint256)' },
inputs: [
{ name: 'from', type: 'address' },
{ name: 'to', type: 'address' },
{ name: 'tokenId', type: 'uint256' }
],
fragment: 'Transfer(address,address,uint256)'
}*/
MyToken smart contract deployment and add to openzeppelin admin module
import { ethers,OpenzeppelinDefender } from "hardhat";
async function main() {
const contractName='MyToken'
const {chainId}=await ethers.provider.getNetwork()
const Contract = await ethers.getContractFactory(contractName);
const contract = await Contract.deploy();
const {interface:abi,address}=await contract.deployed();
//get the abi in json string using the contract interface
const AbiJsonString= OpenzeppelinDefender.Utils.AbiJsonString(abi)
//Obtaining the name of the network through the chainId of the network
const networkName = await OpenzeppelinDefender.Utils.fromChainId(chainId);
//add the contract to the admin
const option={
network:networkName ,
address: address,

abi:AbiJsonString
}
await OpenzeppelinDefender.AdminClient.addContract(option);

Add MyToken to module admin and create a proposal
