Deleveraging

Constructing the DeleverageStruct

Deleveraging requires constructing a DeleverageStruct that specifies how to unwind your position:

// Define how much collateral to withdraw
const collateralAmount = ethers.utils.parseUnits('300', 18);
const repayAmount = ethers.utils.parseUnits('200', 18); // Amount of debt to repay

// Create swap data to convert collateral to borrow asset
// Note: This is an array of swaps, allowing for multi-hop routes
const swapData = [{
  target: '0x1111111254EEB25477B68fb85Ed929f73A960582', // 1inch router
  inputToken: underlyingAsset,
  outputToken: borrowUnderlying,
  inputAmount: ethers.utils.parseUnits('250', 18), // Amount needed to convert to repay debt
  call: '0x...', // Encoded swap call data
}];

// Construct deleverage data
const deleverageData = {
  positionToken: P_TOKEN,
  collateralAmount: collateralAmount,
  borrowToken: E_TOKEN,
  swapData: swapData,
  repayAmount: repayAmount,
  auxData: '0x' // Optional for specialized protocols
};

Executing the Deleverage Operation

// Set slippage tolerance (1%)
const slippage = ethers.utils.parseUnits('0.01', 18);

// Execute the deleverage transaction
const tx = await positionManagement.deleverage(
  deleverageData, 
  slippage,
  2000000
);

const receipt = await tx.wait();
console.log(`Position deleveraged! Tx hash: ${receipt.transactionHash}`);
