Performing a Liquidation

Now, we'll execute the script to perform the liquidation.

1. Identify Liquidatable Accounts

The script contains a list of accounts that are eligible for liquidation. You can get these accounts through this API on the testnet:

• Liquidatable Accounts API

The "Liquidatable Accounts API" for the Hedera mainnet will be made available soon.

2. Configure the Liquidation Parameters

In the script, the liquidate function is set up to liquidate a specific user. Update the parameters accordingly.

async function liquidate() {
  const user = liquidatables[2]; // Index of the user in the list
  const collateralReserve = "0xCollateralAssetAddress"; // Collateral asset address
  const debtReserve = "0xDebtAssetAddress"; // Debt asset address
  const borrowed = ethers.utils.parseUnits("100", 18); // Amount to cover

  // ... rest of the code
}

• user: The address of the user to liquidate.

• collateralReserve: The address of the collateral asset.

• debtReserve: The address of the debt asset.

• borrowed: The amount of debt to cover (in wei).

Replace the placeholders with the actual values based on the user's positions.

3. Execute the Script

Run the script using Hardhat:

npx hardhat run scripts/liquidationFlashLoan/liquidate.ts --network hedera_testnet

4. Monitor the Output

The script will output the progress of the liquidation:

User: 0x78c3edaf3ae5dc69e688d7f41f85c4745ccd552c
Caller address: 0xYourWalletAddress
Collateral Reserve: 0xCollateralAssetAddress
Debt Reserve: 0xDebtAssetAddress
Borrowed: 100

Flash loan successful

If the liquidation is successful, you'll see a confirmation message. If there are errors, the script will output the error details.
