NFT-Backed Loan Repayment Tool

WHAT IT DOES

NFT-Backed Loan Repayment Tool lets you repay outstanding NFT-backed loans and reclaim your collateral NFTs. When you take out a loan using your NFTs as collateral, you must repay the principal plus accrued interest to get your NFTs back. Instead of manually calculating the repayment amount and submitting separate transactions, you add the loan IDs you want to repay, verify the loan status and amount owed, and execute a batch repayment transaction. The tool checks that the loans belong to your wallet, calculates the total repayment amount, and handles the transfer to the lending contract. This is essential for borrowers who want to settle their debts and recover their collectibles.

HOW TO USE

Connect your EVM wallet and select the network. Enter the lending contract address where you originated the loans. In the input area, list the loan IDs you want to repay (one per line). Click "Add loans" to load them, then click "Check loans" to verify each loan's status—the tool checks whether the loan is active, belongs to your wallet, and the total amount owed (principal + interest). Review the status, then click "Repay loans" to execute the repayment transaction. The tool transfers the repayment amount (in native currency) to the lending contract and reclaims your collateral NFTs.

TECHNICAL MECHANISM

The tool first queries the lending contract for each loan ID using a view function that returns the borrower address, collateral count, principal, interest, due date, and repayment status. It filters for active loans where the connected wallet is the borrower. It then calculates the total repayment amount as the sum of principal and interest for all active loans. The tool verifies that the wallet has sufficient native balance to cover the total repayment, then calls the lending contract's repayLoan() function for each loan, sending the repayment amount as value. The lending contract transfers the repayment, marks the loan as repaid, and returns the collateral NFTs to the wallet. The tool uses receipt.effectiveGasPrice for accurate gas reporting and provides progress feedback during the repayment process.

WHAT IT CANNOT SEE

This tool cannot repay loans that are not owned by the connected wallet—ownership is verified before proceeding. It relies on the lending contract supporting repayment via its contract interface; contracts that use non-standard repayment mechanics (e.g., requiring approval of a token, using a different function signature) are not supported. The tool cannot guarantee that the collateral NFTs will be returned if the loan is in default or if the contract has been paused. It also does not handle partial repayments or early repayment discounts beyond what the contract supports.

PLEASE NOTE

Repayment amounts must include both principal and accrued interest—the tool calculates the total owed from the contract. Ensure you have sufficient native tokens (ETH, BNB, etc.) to cover the repayment. The lending contract must be trusted; verify its security and audit status before use. This tool is for EVM chains only and does not support non-EVM networks.
