Claim Collateral / Rent

This page provides instructions on how to claim collateral or rent using the UniBridge SDK.

To ensure proper execution, it is essential to follow the prerequisite steps before proceeding with the current page.

UniBridge Collateralized

Import the UnibridgeCollateralized and PaymentToken modules from the SDK.

const { UnibridgeCollateralized, PaymentToken } = require('@unibridge/sdk');

Instantiate a lender object through the module, providing the lender wallet as a parameter.

const unibridgeLender = new UnibridgeCollateralized(lenderWallet, "<optional_address_to_fill>");

To initiate the stopLending() function, it is necessary to construct the suitable payload object containing the requisite fields and values. Once the payload object is prepared, it can be supplied as an argument while calling the stopLending() function, as demonstrated below.
```
txn = await unibridgeLender.claimCollateral(
    E721_ADDR,
    E721_TOKENID,
    lendingID,
    { gasLimit: 400_000, gasPrice: "400000000000" }
);

receipt = await txn.wait();
console.log(`Claim Collateral Success: ${receipt.transactionHash}`);
```

To ensure the proper execution of the NFT claiming process via UniBridge SDK, the structure of the payloads should be in accordance with the example demonstrated in the previous pages for renting/return or as described in the technical description provided earlier.

UniBridge Collateral Free

Import the UnibridgeCollateralFree and PaymentToken modules from the SDK.

const { UnibridgeCollateralFree, PaymentToken } = require('@unibridge/sdk');

Instantiate a lender object through the module, providing the lender wallet as a parameter.

const unibridgeLender = new UnibridgeCollateralFree(lenderWallet, "<optional_address_to_fill>");

To initiate the stopLending() function, it is necessary to construct the suitable payload object containing the requisite fields and values. Once the payload object is prepared, it can be supplied as an argument while calling the stopLending() function, as demonstrated below.
```
txn = await unibridgeLender.claimRent(
    E721_ADDR,
    E721_TOKENID,
    lendingID,
    { gasLimit: 400_000, gasPrice: "400000000000" }
);
receipt = await txn.wait();
console.log(`Claim Rent Success: ${receipt.transactionHash}`);
```
