Tokenized Invoice Repayment Tool

WHAT IT DOES

This tool provides on-chain repayment and settlement of tokenized invoices, enabling debtors to repay their obligations and settle outstanding debts. It reads your connected wallet address, invoice token contract address, invoice ID, invoice amount, repayment amount, due date, current block timestamp, invoice status, and repayment history. You can then sign and send transactions to repay tokenized invoices, settle debts, and record repayment metadata on-chain. All invoice parameters are displayed in a clear review panel before you sign, so you know exactly what you are repaying. The tool also logs transaction hashes, confirmation status, and gas costs, providing a complete audit trail of all repayment activities.

HOW TO USE

Connect your wallet using the built-in wallet bridge, choose the network that matches your invoice token contract, and paste the contract address. Enter the invoice ID, the repayment amount in raw units, and token decimals for display purposes. The review panel shows all inputs, the current invoice amount, status, and due date before you sign. Use the numbered action buttons: check invoice to view current invoice status, amount, funded amount, due date, and repayment history; repay invoice to make a repayment for the specified amount; or settle debt to fully settle the outstanding debt. You can also view repayment history to see all past repayment timestamps for the invoice. Each transaction is signed sequentially, and the tool displays transaction details and confirmation status.

THE REAL MECHANISM

This tool uses ethers.js v5.7.2 to build and send transactions through the wallet's signer. It does not rely on any hardcoded contract addresses – you paste the invoice token contract you are using, so you are in full control. When you repay an invoice, the tool constructs a contract call to the repayInvoice function, which transfers the repayment amount from your wallet to the funder and updates the invoice's funded balance. When you settle a debt, the tool calls settleDebt, which transfers the remaining amount to fully settle the outstanding debt and marks the invoice as repaid. The tool reads invoice state via getInvoice, which returns the issuer, debtor, amount, funded, due date, discount rate, duration, creation timestamp, and repaid status, as well as getRepaymentHistory for the full history. All transactions are sequential to prevent nonce conflicts, and gas costs are calculated using effectiveGasPrice for accurate post-EIP-1559 reporting.

WHAT IT CANNOT SEE

This tool cannot verify off-chain invoice authenticity, validate debtor creditworthiness, detect invoice fraud, or ensure that the invoice token contract handles repayments correctly. It cannot detect if the invoice is legitimate or if the debtor is creditworthy. The tool also cannot verify that the invoice token contract correctly handles edge cases like partial repayments, overdue invoices, or settlement logic. It cannot simulate the outcome of a transaction before you sign it, nor can it guarantee that the repayment will be processed correctly if the contract is not properly implemented.

PLEASE NOTE

This tool works only on EVM-compatible chains supported by your wallet and provider. Always double-check the contract addresses and invoice IDs before signing. Use testnet first. The tool is a transaction-signing interface and invoice repayment management tool, not a invoice authenticity or creditworthiness verification system.
