How to execute a new loan

In this section, you'll learn how to request ready-to-use transaction data (bytecode) for a new loan.

Prerequisites

• How to Quote for a New Loan

As in the How to Quote for a New Loan section, you can choose either the explicit path or the protocol-agnostic (less explicit) path to get the transaction data.

A) Protocol-Specific Approach (Explicit)

Use this when you want to work with a specific lending protocol.

1. Request Transaction Data Fetch specific protocol information using:

   GET /strategies/:id/bytecode

   Required Parameters:

   Parameter	Description	Example
   action	Type of operation	borrow
   chainId	Blockchain network ID	137 (Polygon)
   protocol	Protocol name	aave
   amount	Borrow amount	10000000 (with decimals)
   asset	Asset to borrow	USDC
   collateralAsset	Collateral asset	ETH
   collateralAmount	Amount of collateral	900000000000000000000000 (0.009 ETH with decimals)

   Example Request:

   GET /strategies/3341412233111/bytecode?action=borrow&chainId=137&protocol=aave&amount=10000000&asset=USDC&collateralAsset=ETH&collateralAmount=900000000000000000000000

   Response:

   {
    "bytecode": [
    	{
    		"to": "0x3c499c542cef5e3811e1192ce70d8cc03d5c3359",
    		"value": "0",
    		"data": "0xa9059cbb0000000000000000000000005900efdd79bc1541cf1f9fd0f56c0a869194430300000000000000000000000000000000000000000000000000000000000003e8"
    	},
    	{
    		"to": "0x794a61358D6845594F94dc1DB02A252b5b4814aD",
    		"value": "0",
    		"data": "0x617ba0370000000000000000000000003c499c542cef5e3811e1192ce70d8cc03d5c335900000000000000000000000000000000000000000000000000000000000f3e58000000000000000000000000d90aa547a8c6b535e8cdce7b67f01b41035d925e0000000000000000000000000000000000000000000000000000000000000000"
    	}
    ]
   }

Our API returns the transaction data as an array of objects. Each object contains to, value, and data fields.

B) Protocol-Agnostic Approach (Less Explicit)

Let our system automatically select the optimal protocol for your needs.

1. Use the Generic Endpoint

GET /strategies/0x0/bytecode

Use the same parameters as the explicit approach above, excluding protocol.

Example Request:

GET /strategies/0x0/bytecode?action=borrow&chainId=137&amount=10000000&asset=USDC&collateralAsset=ETH&collateralAmount=900000000000000000000000

The response format will be identical to the explicit approach.

1. Execute the Transaction You'll need to sign and propagate the transaction data to the blockchain. This happens on your end - we don't touch your funds, custody remains yours.

Next Steps

After executing the loan, you can:

• Manage Loan Positions
• Quote for a New Loan
