How to verify your smart contracts on Pools Chain

Hardhat: Verify Your Contracts

After you deploy your PRC20 Contract successfully, the next step is to verify the source code for your Solidity contracts. This plugin adds the Pool network to the verify task provided by Hardhat-Etherscan

Step 1. Install the package

We need the Hardhat plugin for integration with Poolcan's contract verification service. This plugin needs to be used in conjunction with the Hardhat-Etherscan plugin (v3.1.0 or above).

# Install hardhat-etherscan plugin
npm install --save-dev @nomiclabs/hardhat-etherscan@^3.1.0

And make sure you also have the following dependencies:

npm install ethers dotenv @openzeppelin/contracts
npm install --save-dev solidity-coverage
npm install --save-dev hardhat-gas-reporter

Step 2. Import the plugins

Under Hardhat, add the following statement to your hardhat.config.ts:

...
import "@nomiclabs/hardhat";
import "@nomiclabs/hardhat-etherscan";
...

};

Step 3. Check the supported network list:

Check the list of supported networks:

npx hardhat verify --list-networks

Step 4. Verify the Smart Contract

Obtain your deployed contract address when you deployed the contract (Step 8 in the previous section).

In your hardhat project, run the verify task as shown below. Replace DEPLOYED_CONTRACT_ADDRESS with your deployed contract address, and the constructor arguments that were used to deploy it (if any):

Verify on Pool (Mainnet):

npx hardhat verify --network pool DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1""Constructor argument 2"

Verify on Pool Testnet

npx hardhat verify --network poolTestnet DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1""Constructor argument 2"

Example:

npx hardhat verify --network poolTestnet "0x00e9fd0eaea8325dc31a64e23d91607fdd60d2d1" "My token name" "My token symbol"

​You should now be able to see your contact is verified on Poolscan or Testnet Poolscan and start to read and write your smart contracts.
